2 illustrates correlation data in accordance with some embodiments of the present disclosure.

The correlation data 200 may include information on the degree of correlation 220 between arbitrary items. The correlation data 200 may include correlation information between items belonging to one class or a plurality of classes. The correlation data 200 may be expressed as a two-dimensional or more matrix including a plurality of correlation information.

In the present disclosure, the degree of correlation may be data expressing the degree to which a plurality of items have been related to the same fact or event during a previous point in time. The degree of correlation may be calculated by synthesizing indices related to a plurality of items. The degree of correlation of the plurality of items may be calculated based on a correlation index between the individual items and weight indicators between the individual items.

The relevance indicator between the individual items may be an indicator regarding the frequency with which the individual items are related to the same event. The relevance index between individual items may be recognized based on at least one of metadata and representative data related to the event. For example, the metadata may include event identification information, event-related identification information on a subject, event occurrence time information, and the like. Representative data related to an event may include an event name, an image, an image, a thumbnail, and a voice representing the event. As an example, when the item recommendation method according to the present disclosure is implemented for intellectual property application work, the metadata may include applicant name information, applicant code information, application date, application publication date, registration date, and the like. In this case, the representative data may include a trademark name expressed in text, an image, an image, an audio mark, and a thumbnail thereof. The above-described example is merely an example of the types of metadata and representative data, and the types of metadata and representative data are not limited thereto.

In the present disclosure, the processor 110 may identify events having the same or similar metadata and representative data information, and may identify information on items related to the corresponding events. The processor 110 may generate a relevance index based on the identified item information. As described above, the relevance index may relate to an index in which individual items are related to the same event.

In the item recommendation method according to the present disclosure, the weight index between individual items may be an index quantifying the similarity between intrinsic/non-essential properties of the individual items. The intrinsic property of the item may include intrinsic characteristics of the item, for example, whether the item is a good or a service, whether the item is tangible or intangible, and what object the item is a target of. The non-essential attribute of the item may include a class to which the item belongs, identification information of a group of similar items, and the like. Specifically, the weight index of the plurality of items is determined by whether a common attribute possessed by the individual items exists, the degree of similarity between the attributes possessed by the individual items, whether the individual items appear within the same or similar event, It can be calculated using whether the items belong to the same class. However, this is only an example of factors for determining the weight index, and the elements for determining the weight index are not limited thereto.

The processor 110 may further consider additional factors as well as the above-described examples in determining the weight index. In addition, the processor 110 may selectively determine factors to be considered when determining the weight index. Accordingly, at least one factor affecting the determination of the weight index may be different depending on the execution time of the item recommendation method according to the present disclosure. For example, the processor 110 may determine the weight index based only on whether the attribute information of the item matches. Alternatively, the processor 110 may determine the weight index based on only the item class information. Alternatively, the processor 110 may determine the weight index by using all available weight index determining factors. In addition, with respect to the determination of the weight index, each element may have a different weight, and the weight of each element may be different depending on the execution time of the item recommendation method according to the present disclosure. For example, the weight index may be calculated using a weighted average of values of at least one element selected for determining the weight index. In this case, as described above, the weighted average weight of each element may be different depending on the execution time of the item recommendation method according to the present disclosure. Alternatively, the weight index may be a maximum value, a minimum value, and a median value of values of at least one element selected for determining the weight index. The processor 110 may use various statistical techniques using the at least one factor to determine the weight index. The above-described method of determining the weight index is merely exemplary, and the method of determining the weight index is not limited thereto.

As described above, the processor 110 according to some embodiments of the present disclosure may calculate a degree of correlation between a plurality of items based on the relevance index and the weight index. For example, the processor 110 may derive a degree of correlation by applying a weight index to the relevance index. For example, the processor 110 may derive a degree of correlation based on a four rule operation between the relevance index and the weight index. Alternatively, the processor 110 may derive the correlation by modifying the weight index and applying it to the relevance index. That is, the processor 110 may apply a value obtained by performing a preset operation on the weight index to the relevance index. For example, the preset operation may be a reciprocal number or a formula prepared for specific types of items.

Alternatively, in the present disclosure, the correlation 220 included in the correlation data 200 may be a predicted correlation between items. The predicted correlation may be generated using an eigenvalue decomposition (EVD) or a singular value decomposition (SVD) technique. Specifically, the processor 110 may calculate the raw correlation using the correlation index and the weight index by using the above-described correlation generation technique. The processor 110 may generate predictive correlation data by applying at least one of EVD and SVD techniques to the generated raw correlation data including a plurality of raw correlations. In this way, when the SVD technique is applied, the processor 110 may determine the generated prediction correlation data as the correlation data 200 .

Since the previously collected correlation data is finely adjusted for the various needs of applicants, it may not contain a general tendency for a specific designated product. Accordingly, if an item to be designated together is recommended by applying SVD as described above, a more generalized list of recommended items can be generated.

Also, when one or more first items input to generate a list of recommended items are input, the processor 110 may change the degree of correlation between the first item and related items. That is, when one or more first items are input, the processor 110 may consider that an event has already occurred for all combinations of a plurality of input items. In this case, the processor 110 may increase or decrease the correlation for all combinations of the plurality of items. The processor 110 may generate a list of recommended items based on the degree of correlation to which the change is performed and the correlation data.

This is merely an example of various factors for deriving a degree of correlation using a degree of correlation index and a weight index between items, and factors considered when calculating the degree of correlation and relevance in the present disclosure are not limited thereto.

As described above, the correlation 220 between items may be determined based on one or more events associated with two or more items. In the present disclosure, an event may mean a fact or phenomenon that occurs by using at least one of one or more items and data as the object. When an event occurs, data representing the object of the event and the event itself and metadata information about the event may be generated together.

For example, the event may be the fact of viewing the item, the fact of visiting the item, or the filing of an intellectual property right for the item. In this case, if the event is a viewing of an item, when the event occurs, information about the title of the item, the thumbnail of the item, the identification code of the item, the genre classification of the item, the viewing time of the item, the viewer of the item, etc. can occur Alternatively, if the event is the fact that an intellectual property right for an item is filed, information on the name of the item, representative data related to the item, the identification code (application number) of the application, the time of filing, the applicant, the identification code of the applicant, etc. may occur together. Such information may be used to derive a degree of correlation between a plurality of items by being used to calculate a relevance index and a weight index when calculating the degree of correlation as described above. When the item according to another embodiment of the present invention is a point of interest, the event may include an interaction with the corresponding POI. In this embodiment, the interaction may include a visit fact, a review fact for the POI, a review score for the POI, and the like. In this case, when an event occurs, object information of the POI, thumbnail information of the POI, a hash value of review data for the POI, and the like may be generated together. The processor 110 may calculate a degree of correlation based on such data.

The above description is merely an example of the event, and the type of data representing the event is not limited thereto.

In the present disclosure, the item 210 may be an object that is a target of an event. As described above, an item can have intrinsic and non-essential attributes. Here, the essential attribute of an item may mean an attribute defined without an external attribute definition procedure for the item. The non-essential attribute of an item may mean an attribute defined by an external attribute definition for the item.

For example, the essential properties of the item may include whether the item is a good or a service, whether the item is tangible or intangible, what object the item is a target of, and the like. On the other hand, the non-essential attribute of the item may include identification information of an externally defined item class or similar item group.

The essential and non-essential properties of these items may be pre-stored in the memory 120 and read by the processor 110 . The processor 110 may recognize items related to each of a plurality of events and properties of the items in order to determine a weight index used to calculate a degree of correlation between the plurality of items.

The processor 110 may calculate a weight index between items based on both intrinsic and non-essential properties of the items. However, at least one attribute selected by the processor 110 to calculate the weight index may be variable. Accordingly, the properties of items used to calculate the weight index may be different depending on the execution time of the item recommendation method according to the present disclosure.

Specifically, one item may be associated with at least one of any class and any item group identification information. That is, at least one of the first class and the first similar item group may have items A to F, and at least one of the second class and the second similar item group may include items G to item Z. However, the set of items included in the class and the set of items included in the similar item group are not mutually exclusive. That is, the first item may be included in one or more item groups or one or more classes.

Specifically, the item recommendation method according to the present disclosure may be related to the field of trademark application. In this case, the item 210 may be a designated product and a designated product name.

The item 210 may be recognized from an item database pre-stored in the memory 120 . Alternatively, the item 210 may be input by a user using the item recommendation method according to the present disclosure through an input device (not shown) related to the computing device 100 .

The above-mentioned content is only exemplary content regarding the item, and the content regarding the property of the item, the relationship between the item and the class and the group of similar items, etc. is not limited thereto.

As described above, the item 210 according to the present disclosure may be related to at least one of a class or a group of similar items. In the present disclosure, a class or similar item group may be defined as a type of identification data assigned to items having similar properties.

In the present disclosure, although the properties of items are used to provide class and similar item group information, the properties of the items used are not necessarily dependent on the essential properties of the above-described items. Accordingly, in the present disclosure, non-essential properties of items such as class and similar item group information may be arbitrarily defined.

Therefore, in the present disclosure, a class and a similar item group may be identification information for a set of one or more items having the same and similar essential properties. Alternatively, in the present disclosure, a class and a similar item group may be identification information for a set of one or more items having the same and similar arbitrary properties.

Alternatively, the class or similar item group may be a set of items in which a similarity between items calculated based on a distance between correlation vectors satisfies a preset condition. Here, the correlation vector may include correlation values between an arbitrary item and other items. Referring back to FIG. 2 , the correlation vector for item A may be (0, 1, 4, 5, 14, 7). Also, the correlation vector for the item E may be (14, 6, 22, 1, 0, 4). The processor 110 may determine items having the shortest distance between the correlation vectors as the items corresponding to the first item. The correlation vector may mean a frequency of designation of one item with another item. Accordingly, when the correlation vectors are similar (ie, when the distance between the correlation vectors is short), the two items can be regarded as similar items. Accordingly, since the correlation vector for similar items can be reflected in the list of recommended items, the protection of trademark rights can be further three-dimensionally promoted.

Non-essential attributes such as class and similar item group information for an item may be stored in the memory 120 and read by the processor 110 . Accordingly, when calculating the degree of correlation between the plurality of items, the processor 110 recognizes each of the plurality of items, and reads, if necessary, at least one or more class and similar item group information for each of the items from the memory 120 . can be recognised.

For example, when items A to F in the correlation data 200 shown in FIG. 2 have in common the essential properties of “food” and “service industry,” they may belong to the first class or the first group of similar items. can This is only an example related to a class or similar item group, and the content regarding the class and similar item group is not limited to the above-described content.

One or more non-essential attributes of these items may exist. As described above, the processor 110 may determine the weight index using whether the non-essential properties are the same, the similarity between the non-essential properties, and the like. Specifically, the processor 110 may recognize a measure of identity and similarity between non-essential attributes (ie, degree of similarity). The similarity between these non-essential attributes may be pre-stored in the memory 120 and read by the processor 110 . Alternatively, when the class or similar item group information is text information, the processor 110 performs a conventional calculation method of similarity between strings, such as Levenshtein Distance, Hamming Distance, Smith-Waterman, and Sørensen-Dice Coefficient, or a neural for text processing. The similarity between non-essential attributes can be calculated using a network-based word similarity technique. Alternatively, the processor 110 may calculate the similarity between information of a class or similar item group in the form of text information based on a neural network that calculates a similarity between texts in which non-essential properties of items are expressed.

Since the above description is only exemplary, the method of calculating the similarity between non-essential information, particularly a class and a group of similar items, should not be limited to the above-described example.

The processor 110 may calculate a weight index by using the similarity between the calculated non-essential attributes. As an example, the processor 110 may assign a higher weight as the non-essential properties are similar, and conversely assign a lower weight as the non-essential properties are different. Conversely, in order to recommend several items having different non-essential properties, the processor 110 may give a lower weight as the non-essential properties are similar, and may give a higher weight as the non-essential properties are different. As described above, the processor 110 may perform such a series of selections without direct instruction from the user. For example, when the user grants "multi-class selection", the processor 110 may assign a higher weight index as the non-essential properties are different based on this input. Furthermore, when the classes of at least two items among the plurality of first items selected by the user to receive the item recommendation are different, the processor 110 automatically recognizes this as "multi-class selection" and weights it as non-essential properties are different. indicators can be given high. Conversely, when the classes of the plurality of first items selected by the user to receive the item recommendation are all the same, the processor 110 automatically recognizes this as "single class selection", and gives a higher weight index as the non-essential properties are similar. You can do it.

Based on various similar methods, the processor 110 may calculate correlation and correlation data so as to generate an item recommendation list suitable for a user's needs.

In FIG. 2, only items A to F are shown in the first class. However, a class can contain a very large number of items. In this case, when the correlation data 200 is expressed as a two-dimensional or more matrix, most of the elements of the matrix may be zero. In this case, the correlation data 200 may be a sparse matrix.

The processor 110 may express the correlation data 200 as a compressed sparse matrix. Alternatively, the processor 110 may store the correlation data 200 using a dictionary key, a list of lists (LIL), a coordinate list (COO), a compressed sparse row (CSR), or the like. However, since these are merely examples of a method for compressing and expressing correlation data, a method for compressing and expressing correlation data is not limited thereto.

The processor 110 may save memory space by compressing and expressing the correlation data 200 . When the item recommendation method according to the present disclosure is applied in relation to a trademark application, the item 210 may correspond to a designated product. Since there are hundreds of thousands of known designated product names, memory space can be greatly saved by using the sparse matrix compression method according to some embodiments of the present disclosure.

3 illustrates metadata and representative data according to some embodiments of the present disclosure.

As described above, in order to calculate the degree of correlation by the method according to the present disclosure, metadata information related to an event may be generated. In the present disclosure, the metadata 300 may mean secondary information related to an event. As described above with reference to FIG. 2 , the metadata may include event identification information, event-related identification information on a subject, event occurrence time information, and the like. In addition, as shown in FIG. 3 , when the item recommendation method according to the present disclosure is used to recommend a designated product when applying for a trademark, the metadata 300 may include an applicant, an application date, an application number, and the like.

In some embodiments, the processor 110 may increase the relevance index for calculating the relevance based on the identity and similarity of the meta data. For example, the processor 110 may recognize one or more events corresponding to the same metadata. Here, the processor 110 may recognize all one or more items related to one or more events corresponding to the same metadata. As another example, the processor 110 may determine a degree of similarity between metadata and recognize all one or more items related to one or more events related to similar metadata. Specifically, the processor 110 may calculate the similarity between meta data using the method of determining the similarity of text and images and the neural network-based methods as described above with reference to FIG. 2 . The above-described example is merely an example of a method for the processor 110 to recognize one or more items from one or more events corresponding to the same and similar metadata, and the method for recognizing the one or more items is not limited thereto.

The processor 110 may increase the relevance index for the recognized combination of the one or more items. For example, when a plurality of items are related within the same event, the processor 110 may increase the relevance index for all combinations of the plurality of items. Alternatively, the processor 110 may increase the relevance index for all combinations of a plurality of items related to a plurality of events corresponding to similar metadata. When increasing the relevance index between items related to a plurality of events corresponding to the similar metadata, the processor 110 may apply the similarity between the metadata of each event. For example, when the similarity between the first meta data related to the first event and the second metadata related to the second event is 0.6, the processor 110 performs the first item related to the first event and the second metadata related to the second event. When increasing the relevance index between 2 items, 0.6 can be applied (multiplied) to 1 to increase 0.6.

When the processor 110 increases the relevance index with respect to a plurality of events related to similar metadata, the processor 110 may regard events having similar metadata as one event. In this case, the processor 110 may increase the relevance index only once for all items related to the event corresponding to the same and similar metadata.

Conversely, when increasing the relevance index with respect to a plurality of events related to similar metadata, the processor 110 may consider each event as a separate event and increase the relevance index overlappingly.

An embodiment in which the item recommendation method according to the present disclosure is used to provide a list of recommended designated products in a trademark application will be described with reference to FIG. 3 .

In this case, the processor 110 may recognize a plurality of trademark application cases having the same similar applicant, the same and similar applicant code, the same and similar application number, and the same and similar application time. The processor 110 may recognize all items included in a plurality of recognized trademark application cases. Furthermore, the processor 110 may calculate a degree of similarity between applicant information, a degree of similarity between applicant codes, a degree of similarity between application numbers, and a degree of similarity between filing times in a plurality of trademark application cases.

The processor 110 may increase the relevance index for all combinations of recognized items. As described above, in order to increase the relevance index, the processor 110 may recognize all the trademark application cases as a single trademark application event, and increase the relevance index by 1 for all combinations of related items. Alternatively, the processor 110 may increase the relevance index for each individual trademark event. When the processor 110 increases the relevance index for a combination of items for each individual trademark event, the processor 110 may increase the relevance index for the combination of items by reflecting the similarity value between the computed metadata. there is.

Since the above is only an example of a method for increasing the correlation between items using the metadata 300 , the method for increasing the correlation between items is not limited thereto.

If a trademark applicant operates a single industry and wants multiple protections for similar trademarks, it is highly likely that similar trademarks will be applied continuously for the same designated product. In this case, if the correlation is increased for each application, there is a high possibility that the correlation value between the designated products will be biased. Accordingly, the degree of correlation and the correlation data may be different even when a multi-class application for a trademark and a plurality of single-class applications for a trademark are performed for substantially the same purpose. By using these characteristics, in the present disclosure, according to a specific method of increasing the correlation using metadata, the correlation data 200 that meets the needs of the applicant can be generated.

For example, if the applicant wants broad protection for trademark rights, increasing the correlation according to the applicant (or applicant code) can control the bias in the correlation value between designated products, so correlation for acquiring a wide range of trademark rights Data 200 may be generated.

Conversely, when the applicant desires overlapping protection for trademark rights, the degree of correlation (relevance index) can be increased for each of a plurality of applications (events). Accordingly, correlation data 200 suitable for overlapping protection of trademarks may be generated.

In the present disclosure, the representative data 400 may be data serving to represent the event itself.

In some embodiments according to the present disclosure, representative data (related to an event) may include an event name representing the event, an image, a video, a thumbnail, a voice, and the like. Furthermore, the representative data may be multimedia data in which the event name, image, video, thumbnail, voice, and the like are combined. Since the above description is only an example of the type of representative data, the type of representative data is not limited thereto.

In the present disclosure, the processor 110 may generate a representative data group. As for the representative data group, the processor 110 may determine the degree of similarity between the representative data to generate the representative data group. For example, the processor 110 may determine the similarity between the representative data based on a neural network model that detects the similarity of images or words. When the determined similarity satisfies a preset criterion, the processor 110 may include representative data in one representative data group. Since the above description is only an example of a method for forming the representative data group, the method for generating the representative data group is not limited thereto.

It will be described with reference to FIG. 3 . As illustrated in FIG. 3 , the representative data 400 may be a mark in the form of an image. Alternatively, the representative data 400 may be a brand name indicated by 'CHANEL'. In addition, the representative data may include both a mark and a name in the form of an image shown. Furthermore, the representative data may include only a core part of the data (hereinafter, referred to as a 'subject'). For example, referring to the representative data 400 shown in FIG. 3 , for some representative data, an additional figure or pattern is appended to the 'CHANEL' text. In this case, the processor 110 may recognize only the 'CHANEL' portion excluding the appended figures as the representative data 400 rather than recognizing the entire image of the corresponding mark as the representative data 400 .

Since this is only an example of the type of representative data, the type of representative data according to the present disclosure is not limited thereto.

The processor 110 may generate a representative data group and increase correlation between items corresponding to the representative data group. In the present disclosure, a representative data group may mean a set of similar representative data. Referring to FIG. 3 , the illustrated 'CHANEL' and similar marks may be grouped into one representative data group. The processor 110 may determine the similarity between the representative data to generate the representative data group. For example, the processor 110 may determine the similarity between the representative data based on a neural network model that detects the similarity of images or words. When the determined similarity satisfies a preset criterion, the processor 110 may include representative data in one representative data group. The processor 110 may recognize items designated in each of the trademark applications included in the representative data group, and increase a correlation index between the items. In this case, the processor 110 may recognize the trademark applications included in the representative data group as one trademark application, and increase the relevance index by 1 for all combinations of each of the items.

Alternatively, the processor 110 may overlap the relevance index by reflecting the degree of similarity between the calculated representative data for each trademark application, regardless of whether the representative data group is generated. For example, when the similarity between the representative data of the first application and the representative data of the second application is 0.6, the processor 110 sets the relevance index by 0.6 in a combination between the items to which one or more items included in the second application are related. can increase

Alternatively, when the degree of similarity between the representative data is applied when the degree of relevance is increased, the reciprocal number of the degree of similarity between the representative data may be reflected in the degree of relevance. That is, when the similarity between the representative data is 0.2, when the relevance index is increased, 5, which is the reciprocal of the similarity, is multiplied by the reciprocity index increase value 1 to increase 5. In this case, the amount of increase in the correlation between the trademark applications with low similarity between the representative data will be larger.

When a trademark applicant operates in a single industry, relates to a single brand, or wants overlapping protection for similar trademarks, it is highly likely that similar trademarks will be applied continuously for the same designated product. In this case, if the correlation is increased only for each application, there is a high possibility that the correlation value between designated products will be biased.

Accordingly, the correlation data 200 that meets the needs of the applicant may be generated according to which metadata is used to increase the correlation in the item recommendation method according to the present disclosure.

For example, if the applicant wants broad protection for trademark rights, increasing the correlation according to the applicant (or applicant code) can control the bias in the correlation value between designated products, so correlation for acquiring a wide range of trademark rights Data 200 may be generated.

Conversely, when the applicant desires overlapping protection for trademark rights, correlation data 200 suitable for overlapping protection of trademarks may be generated by increasing the correlation for each application.

This depends on how to evaluate the similarity of the representative data 400 when the same items are overlapped and designated together. For example, when the applicant desires overlapping protection for trademark rights, the processor 110 may determine to reflect the similarity in increasing the relevance index. Conversely, when the applicant wants broad protection for trademark rights, the processor 110 may determine to consider all applications included in the representative data group as a single application.

4 illustrates an item, an item class, and a similar item group according to some embodiments of the present disclosure.

As described above with reference to FIG. 2 , an item may have intrinsic properties and non-essential properties, and information about a class and a group of similar items is related to the non-essential properties of the items. As described above, information about a class and a group of similar items is not necessarily determined based on essential properties of a plurality of items. Accordingly, it should be understood that a class and a group of similar items may be determined based on arbitrary properties of the items regardless of the description below.

It will be described with reference to FIG. 4 as an example.

Referring to FIG. 4 , the items (designated products) listed on the right side of the table are all related to the distribution business. Therefore, the common essential property of items can be said to be "distribution business". In this case, the processor 110 may determine "35 class" corresponding to "distribution business" as a class.

Based on this class, the processor 110 may recognize a class of each of the items that are designated together, and when items belonging to a different class are designated together, the correlation value may be increased by weighting it.

One or more non-essential attributes of these items may exist. As described above, the processor 110 may determine the weight index using whether the non-essential properties are the same, the similarity between the non-essential properties, and the like. Specifically, the processor 110 may recognize a measure of identity and similarity between non-essential attributes (ie, degree of similarity). The similarity between these non-essential attributes may be pre-stored in the memory 120 and read by the processor 110 . Alternatively, when the class or similar item group information is text information, the processor 110 performs a conventional calculation method of similarity between strings, such as Levenshtein Distance, Hamming Distance, Smith-Waterman, and Sørensen-Dice Coefficient, or a neural for text processing. The similarity between non-essential attributes can be calculated using a network-based word similarity technique. Alternatively, the processor 110 may calculate the similarity between information of a class or similar item group in the form of text information based on a neural network that calculates a similarity between meanings implied by non-essential properties of items. Since the above-mentioned contents are merely exemplary, the method of calculating the similarity between non-essential information, in particular, a class and a group of similar items should not be limited to the above-described example.

The processor 110 may calculate a weight index by using the similarity between the calculated non-essential attributes. As an example, the processor 110 may assign a higher weight as the non-essential properties are similar, and conversely assign a lower weight as the non-essential properties are different. Conversely, in order to recommend several items having different non-essential properties, the processor 110 may give a lower weight as the non-essential properties are similar, and may give a higher weight as the non-essential properties are different. As described above, the processor 110 may perform such a series of selections without direct instruction from the user.

For example, when the user grants "multi-class selection", the processor 110 may assign a higher weight index as the non-essential properties are different based on this input. Furthermore, when the classes of at least two items among the plurality of first items selected by the user to receive the item recommendation are different, the processor 110 automatically recognizes this as "multi-class selection" and weights it as non-essential properties are different. indicators can be given high. Conversely, when the classes of the plurality of first items selected by the user to receive the item recommendation are all the same, the processor 110 automatically recognizes this as "single class selection", and gives a higher weight index as the non-essential properties are similar. You can do it.

Based on various similar methods, the processor 110 may calculate correlation and correlation data so as to generate an item recommendation list suitable for a user's needs.

5 is a schematic diagram illustrating a network function according to an embodiment of the present disclosure;

Throughout this specification, computational model, neural network, network function, and neural network may be used interchangeably. A neural network may be composed of a set of interconnected computational units, which may generally be referred to as nodes. These nodes may also be referred to as neurons. A neural network is configured to include at least one or more nodes. Nodes (or neurons) constituting the neural networks may be interconnected by one or more links.

In the neural network, one or more nodes connected through a link may relatively form a relationship between an input node and an output node. The concepts of an input node and an output node are relative, and any node in an output node relationship with respect to one node may be in an input node relationship in a relationship with another node, and vice versa. As described above, an input node-to-output node relationship may be created around a link. One or more output nodes may be connected to one input node through a link, and vice versa.

In the relationship between the input node and the output node connected through one link, the value of the data of the output node may be determined based on data input to the input node. Here, a link interconnecting the input node and the output node may have a weight. The weight may be variable, and may be changed by a user or an algorithm in order for the neural network to perform a desired function. For example, when one or more input nodes are interconnected to one output node by respective links, the output node sets values input to input nodes connected to the output node and links corresponding to the respective input nodes. An output node value may be determined based on the weight.

As described above, in a neural network, one or more nodes are interconnected through one or more links to form an input node and an output node relationship in the neural network. The characteristics of the neural network may be determined according to the number of nodes and links in the neural network, the correlation between the nodes and the links, and the value of a weight assigned to each of the links. For example, when the same number of nodes and links exist and there are two neural networks having different weight values of the links, the two neural networks may be recognized as different from each other.

A neural network may consist of a set of one or more nodes. A subset of nodes constituting the neural network may constitute a layer. Some of the nodes constituting the neural network may configure one layer based on distances from the initial input node. For example, a set of nodes having a distance of n from the initial input node may constitute n layers. The distance from the initial input node may be defined by the minimum number of links that must be passed to reach the corresponding node from the initial input node. However, the definition of such a layer is arbitrary for description, and the order of the layer in the neural network may be defined in a different way from the above. For example, a layer of nodes may be defined by a distance from the final output node.

The initial input node may mean one or more nodes to which data is directly input without going through a link in a relationship with other nodes among nodes in the neural network. Alternatively, in a relationship between nodes based on a link in a neural network, it may mean nodes that do not have other input nodes connected by a link. Similarly, the final output node may refer to one or more nodes that do not have an output node in relation to other nodes among nodes in the neural network. In addition, the hidden node may mean nodes constituting the neural network other than the first input node and the last output node.

The neural network according to an embodiment of the present disclosure may be a neural network in which the number of nodes in the input layer may be the same as the number of nodes in the output layer, and the number of nodes decreases and then increases again as progresses from the input layer to the hidden layer. can Also, in the neural network according to another embodiment of the present disclosure, the number of nodes in the input layer may be less than the number of nodes in the output layer, and the number of nodes may be reduced as the number of nodes progresses from the input layer to the hidden layer. there is. In addition, the neural network according to another embodiment of the present disclosure may be a neural network in which the number of nodes in the input layer may be greater than the number of nodes in the output layer, and the number of nodes increases as the number of nodes progresses from the input layer to the hidden layer. can The neural network according to another embodiment of the present disclosure may be a neural network in a combined form of the aforementioned neural networks.

A deep neural network (DNN) may refer to a neural network including a plurality of hidden layers in addition to an input layer and an output layer. Deep neural networks can be used to identify the latent structures of data. In other words, it can identify the potential structure of photos, texts, videos, voices, and music (e.g., what objects are in the photos, what the text and emotions are, what the texts and emotions are, etc.) . Deep neural networks include convolutional neural networks (CNNs), recurrent neural networks (RNNs), auto encoders, generative adversarial networks (GANs), and restricted boltzmann machines (RBMs). machine), a deep belief network (DBN), a Q network, a U network, a Siamese network, and a Generative Adversarial Network (GAN). The description of the deep neural network described above is only an example, and the present disclosure is not limited thereto.

In an embodiment of the present disclosure, the network function may include an autoencoder. The auto-encoder may be a kind of artificial neural network for outputting output data similar to input data. The auto encoder may include at least one hidden layer, and an odd number of hidden layers may be disposed between the input/output layers. The number of nodes in each layer may be reduced from the number of nodes of the input layer to an intermediate layer called the bottleneck layer (encoding), and then expanded symmetrically with reduction from the bottleneck layer to the output layer (symmetrically with the input layer). The auto-encoder can perform non-linear dimensionality reduction. The number of input layers and output layers may correspond to a dimension after preprocessing the input data. In the auto-encoder structure, the number of nodes of the hidden layer included in the encoder may have a structure that decreases as the distance from the input layer increases. If the number of nodes in the bottleneck layer (the layer with the fewest nodes located between the encoder and decoder) is too small, a sufficient amount of information may not be conveyed, so a certain number or more (e.g., more than half of the input layer, etc.) ) may be maintained.

The neural network may be trained using at least one of supervised learning, unsupervised learning, semi-supervised learning, and reinforcement learning. Learning of the neural network may be a process of applying knowledge for the neural network to perform a specific operation to the neural network.

A neural network can be trained in a way that minimizes output errors. In the training of a neural network, iteratively input the training data into the neural network, calculate the output of the neural network and the target error for the training data, and calculate the error of the neural network from the output layer of the neural network to the input layer in the direction to reduce the error. It is a process of updating the weight of each node in the neural network by backpropagation in the direction. In the case of teacher learning, learning data in which the correct answer is labeled in each learning data is used (ie, labeled learning data), and in the case of comparative learning, the correct answer may not be labeled in each learning data. That is, for example, learning data in the case of teacher learning related to data classification may be data in which categories are labeled in each of the learning data. Labeled training data is input to the neural network, and an error can be calculated by comparing the output (category) of the neural network with the label of the training data. As another example, in the case of comparison learning related to data classification, an error may be calculated by comparing the input training data with the neural network output. The calculated error is back propagated in the reverse direction (ie, from the output layer to the input layer) in the neural network, and the connection weight of each node of each layer of the neural network may be updated according to the back propagation. The change amount of the connection weight of each node to be updated may be determined according to a learning rate. The computation of the neural network on the input data and the backpropagation of errors can constitute a learning cycle (epoch). The learning rate may be applied differently according to the number of repetitions of the learning cycle of the neural network. For example, in the early stage of learning of a neural network, a high learning rate can be used to enable the neural network to quickly obtain a certain level of performance, thereby increasing efficiency, and using a low learning rate at a later stage of learning can increase accuracy.

In the training of neural networks, in general, the training data may be a subset of real data (that is, data to be processed using the trained neural network), and thus, the error on the training data is reduced, but the error on the real data is reduced. There may be increasing learning cycles. Overfitting is a phenomenon in which errors on actual data increase by over-learning on training data as described above. For example, a phenomenon in which a neural network that has learned a cat by seeing a yellow cat does not recognize that it is a cat when it sees a cat other than yellow may be a type of overfitting. Overfitting can act as a cause of increasing errors in machine learning algorithms. In order to prevent such overfitting, various optimization methods can be used. In order to prevent overfitting, methods such as increasing the training data, regularization, and dropout that deactivate some of the nodes of the network in the process of learning, and the use of a batch normalization layer are applied. can

A computer-readable medium storing a data structure is disclosed according to an embodiment of the present disclosure.

The data structure may refer to the organization, management, and storage of data that enables efficient access and modification of data. A data structure may refer to an organization of data to solve a specific problem (eg, data retrieval, data storage, and data modification in the shortest time). A data structure may be defined as a physical or logical relationship between data elements designed to support a particular data processing function. The logical relationship between data elements may include a connection relationship between user-defined data elements. Physical relationships between data elements may include actual relationships between data elements physically stored on a computer-readable storage medium (eg, persistent storage ). A data structure may specifically include a set of data, relationships between data, and functions or instructions applicable to data. Through an effectively designed data structure, the computing device can perform an operation while using the resource of the computing device to a minimum. Specifically, the computing device may increase the efficiency of operations, reads, insertions, deletions, comparisons, exchanges, and retrievals through effectively designed data structures.

A data structure may be classified into a linear data structure and a non-linear data structure according to the type of the data structure. The linear data structure may be a structure in which only one piece of data is connected after one piece of data. The linear data structure may include a list, a stack, a queue, and a deck. A list may mean a set of data in which an order exists internally. The list may include a linked list. The linked list may be a data structure in which data is linked in such a way that each data is linked in a line with a pointer. In a linked list, a pointer may contain information about a link with the next or previous data. A linked list may be expressed as a single linked list, a doubly linked list, or a circularly linked list according to a shape. A stack can be a data enumeration structure with limited access to data. A stack can be a linear data structure in which data can be manipulated (eg, inserted or deleted) at only one end of the data structure. The data stored in the stack may be a data structure (LIFO-Last in First Out). A queue is a data listing structure that allows limited access to data, and unlike a stack, it may be a data structure that is stored later (FIFO-First in First Out). A deck can be a data structure that can process data at either end of the data structure.

The non-linear data structure may be a structure in which a plurality of data is connected after one data. The nonlinear data structure may include a graph data structure. A graph data structure may be defined as a vertex and an edge, and the edge may include a line connecting two different vertices. A graph data structure may include a tree data structure. The tree data structure may be a data structure in which one path connects two different vertices among a plurality of vertices included in the tree. That is, it may be a data structure that does not form a loop in the graph data structure.

Throughout this specification, computational model, neural network, network function, and neural network may be used interchangeably. Hereinafter, the neural network is unified and described. The data structure may include a neural network. And the data structure including the neural network may be stored in a computer-readable medium. Data structures, including neural networks, also include preprocessed data for processing by the neural network, data input to the neural network, weights of the neural network, hyperparameters of the neural network, data obtained from the neural network, activation functions associated with each node or layer of the neural network, and neural networks. It may include a loss function for learning of . A data structure comprising a neural network may include any of the components disclosed above. That is, the data structure including the neural network includes preprocessed data for processing by the neural network, data input to the neural network, weights of the neural network, hyperparameters of the neural network, data obtained from the neural network, activation function associated with each node or layer of the neural network, and neural network It may be configured to include all or any combination thereof, such as a loss function for learning of . In addition to the above-described configurations, a data structure including a neural network may include any other information that determines a characteristic of a neural network. In addition, the data structure may include all types of data used or generated in the operation process of the neural network, and is not limited to the above. Computer-readable media may include computer-readable recording media and/or computer-readable transmission media. A neural network may be composed of a set of interconnected computational units, which may generally be referred to as nodes. These nodes may also be referred to as neurons. A neural network is configured to include at least one or more nodes.

The data structure may include data input to the neural network. A data structure including data input to the neural network may be stored in a computer-readable medium. The data input to the neural network may include learning data input in a neural network learning process and/or input data input to the neural network in which learning is completed. Data input to the neural network may include pre-processing data and/or pre-processing target data. The preprocessing may include a data processing process for inputting data into the neural network. Accordingly, the data structure may include data to be pre-processed and data generated by pre-processing. The above-described data structure is merely an example, and the present disclosure is not limited thereto.

The data structure may include the weights of the neural network. (In this specification, weight and parameter may be used interchangeably.) And the data structure including the weight of the neural network may be stored in a computer-readable medium. The neural network may include a plurality of weights. The weight may be variable, and may be changed by a user or an algorithm in order for the neural network to perform a desired function. For example, when one or more input nodes are interconnected to one output node by respective links, the output node sets values input to input nodes connected to the output node and links corresponding to the respective input nodes. A data value output from the output node may be determined based on the weight. The above-described data structure is merely an example, and the present disclosure is not limited thereto.

By way of example and not limitation, the weight may include a weight variable in a neural network learning process and/or a weight in which neural network learning is completed. The variable weight in the neural network learning process may include a weight at a time point at which a learning cycle starts and/or a weight variable during the learning cycle. The weight for which neural network learning is completed may include a weight for which a learning cycle is completed. Accordingly, the data structure including the weights of the neural network may include a data structure including the weights that vary in the neural network learning process and/or the weights on which the neural network learning is completed. Therefore, it is assumed that the above-described weights and/or combinations of weights are included in the data structure including the weights of the neural network. The above-described data structure is merely an example, and the present disclosure is not limited thereto.

The data structure including the weights of the neural network may be stored in a computer-readable storage medium (eg, memory, hard disk) after being serialized. Serialization can be the process of converting a data structure into a form that can be reconstructed and used later by storing it on the same or a different computing device. The computing device may serialize the data structure to send and receive data over the network. A data structure including weights of the serialized neural network may be reconstructed in the same computing device or in another computing device through deserialization. The data structure including the weight of the neural network is not limited to serialization. Furthermore, the data structure including the weights of the neural network is a data structure to increase computational efficiency while using the resources of the computing device to a minimum (e.g., B-Tree, Trie, m-way search tree, AVL tree, Red-Black Tree). The foregoing is merely an example, and the present disclosure is not limited thereto.

The data structure may include hyper-parameters of the neural network. In addition, the data structure including the hyperparameters of the neural network may be stored in a computer-readable medium. The hyper parameter may be a variable variable by a user. Hyperparameters are, for example, learning rate, cost function, number of iterations of the learning cycle, weight initialization (e.g., setting the range of weight values to be initialized for weights), Hidden Unit The number (eg, the number of hidden layers, the number of nodes of the hidden layer) may be included. The above-described data structure is merely an example, and the present disclosure is not limited thereto.

In the present disclosure, the neural network as described above includes event-related metadata including event identification information, event-related entity identification information, event occurrence time information, etc., event name, event image, event image, It may be used to derive a degree of similarity between representative data related to an event including an event thumbnail, an event voice, and the like, an essential attribute of an item, and a non-essential attribute of an item, such as a class or similar representative data group.

Specifically, in the present disclosure, the similarity between representative data may be based on a similarity measurement method between images using a convolutional neural network (CNN) or a similarity measurement method between words using a natural language processing technique.

6 illustrates a list of recommended items according to some embodiments of the present disclosure.

In the present disclosure, the processor 110 may generate a list of recommended items based on the degree of correlation.

In the present disclosure, the recommended item is an item that is recommended to be designated together with the first item, and may be determined based on the correlation 220 included in the correlation data 200 .

Referring to FIG. 6 , items E, F, and D were determined as recommended items for item A. The processor 110 may determine the recommended items in the order in which the correlation with the item A is high.

The list of recommended items for item A illustrated in FIG. 6 is exemplary, and the number of recommended items and criteria for determining the recommended items are not limited thereto.

7 is a flowchart illustrating a process in which a processor performs an item recommendation method according to some embodiments of the present disclosure.

The processor 110 may generate correlation data between items ( S100 ).

As described above in FIG. 2 , the correlation data 200 includes information on the correlation 220 between one or more items. The correlation data 200 may be expressed as two-dimensional or more matrix information. In order to space-efficiently store the correlation data 200 in the memory 120 , the processor 110 may express the correlation data 200 as a compressed sparse matrix. Alternatively, the processor 110 may store the correlation data 200 using a dictionary key, a list of lists (LIL), a coordinate list (COO), a compressed sparse row (CSR), or the like. However, since these are merely examples of a method for compressing and expressing the correlation data, the method for compressing and expressing the correlation data 200 is not limited thereto.

The processor 110 may save memory space by compressing and expressing the correlation data 200 . When the item recommendation method according to the present disclosure is applied in relation to a trademark application, the item 210 may correspond to a designated product. Through this, the memory 120 can be used efficiently and the input/output speed for the correlation data 200 can be very fast.

The processor 110 may extract one or more items corresponding to the first item ( S200 ).

In the present disclosure, the first item may be a target on which an event is performed. In particular, when the event is a trademark application, the first item may be any designated product that the applicant intends to apply for. The first item may be directly input by the user through the input device.

One or more items corresponding to the first item extracted by the processor 110 may be items determined to be similar to the first item. As described above in FIG. 2 , for example, the degree of similarity of any two items may be determined based on the similarity of their essential/non-essential properties. The processor 110 may determine that the two items are similar when the degree of similarity between any two items satisfies a preset condition.

For example, the processor 110 may determine that items belonging to the same class or belonging to the same similar item group are similar. Alternatively, the processor 110 may determine the similar item by using the essential attribute of the first item. For example, with respect to the intrinsic attribute of the first item, it may be determined that the second item having the intrinsic attribute matching a certain ratio or more is an item similar to the first item. The processor 110 may determine an item similar to the first item based on a model using a neural network as shown in FIG. 5 or a conventional text similarity analysis algorithm such as Levenshtein Distance. The processor 110 may extract the determined similar items as one or more items corresponding to the first item.

Alternatively, one or more items extracted corresponding to the first item may be a set of items in which a distance between correlation vectors satisfies a preset condition. The correlation vector may be a vector expressing correlation values of an arbitrary item with one or more other items. Referring back to FIG. 2 , the correlation vector for item A may be (0, 1, 4, 5, 14, 7). Also, the correlation vector for the item E may be (14, 6, 22, 1, 0, 4). The processor 110 may determine items having the shortest distance between the first item and the correlation vector as the item corresponding to the first item.

The correlation vector may mean a frequency in which one item is related to another item in the same event. Accordingly, when the correlation vectors are similar (ie, when the distance between the correlation vectors is short), the two items can be regarded as similar items. Accordingly, since the correlation vector for similar items can be reflected in the list of recommended items, the protection of trademark rights can be further three-dimensionally promoted.

Alternatively, the processor 110 according to some embodiments of the present disclosure may extract one or more items corresponding to the first item based on the distance between the correlation vectors.

Here, the correlation vector may include correlation values between an arbitrary item and other items.

Referring back to FIG. 2 , the correlation vector for item A may be (0, 1, 4, 5, 14, 7). Also, the correlation vector for the item E may be (14, 6, 22, 1, 0, 4).

The processor 110 may determine items having the shortest distance between the correlation vectors as the items corresponding to the first item.

The correlation vector may mean a frequency of designation of one item with another item. Accordingly, when the correlation vectors are similar (ie, when the distance between the correlation vectors is short), the two items can be regarded as similar items. Accordingly, since the correlation vector for similar items can be reflected in the list of recommended items, the protection of trademark rights can be further three-dimensionally promoted.

The processor 110 may generate a list of recommended items for the first item based on the correlation data between the items and the extracted one or more items ( S300 ).

In the present disclosure, a recommended item is an item recommended to appear together with a first item in the event, and may be determined based on the correlation 220 included in the correlation data 200 . As an example, it is assumed that the second item and the third item are extracted as items corresponding to the first item.

In this case, the processor 110 may recognize correlation information of the first item, the second item, and the third item from the correlation data 200 . The processor 110 may aggregate (eg, add correlation values for the same item) of the recognized relevance information of the first to third items. The processor 110 may generate a list of recommended items from the synthesized relevance information in an order of increasing relevance information.

Since this is only an example of a method for generating a list of recommended items, the content of the present disclosure is not limited thereto.

The processor 110 may calculate a weight index by using the similarity between the calculated non-essential attributes. As an example, the processor 110 may assign a higher weight as the non-essential properties are similar, and conversely assign a lower weight as the non-essential properties are different. Conversely, in order to recommend several items having different non-essential properties, the processor 110 may give a lower weight as the non-essential properties are similar, and may give a higher weight as the non-essential properties are different. As described above, the processor 110 may perform such a series of selections without direct instruction from the user. For example, when the user grants "multi-class selection", the processor 110 may assign a higher weight index as the non-essential properties are different based on this input. Furthermore, when the classes of at least two items among the plurality of first items selected by the user to receive the item recommendation are different, the processor 110 automatically recognizes this as "multi-class selection" and weights it as non-essential properties are different. indicators can be given high. Conversely, when the classes of the plurality of first items selected by the user to receive the item recommendation are all the same, the processor 110 automatically recognizes this as "single class selection", and gives a higher weight index as the non-essential properties are similar. You can do it.

When generating the recommended item list, the processor 110 includes only items corresponding to the same class or similar item group as the first item in the recommended item list, or only items corresponding to a different class or different similar item group from the first item. can be included in the list of recommended items.

According to the above-described method, it is possible to prevent a situation in which unnecessary items are recommended depending on whether the applicant desires a single-class application or a multi-class application.

8 is a flowchart illustrating a process in which a processor performs a method of generating correlation data between items according to some embodiments of the present disclosure.

The processor 110 may recognize the class of each of the plurality of items (S110).

In the present disclosure, a class or similar item group may be defined as a type of identification data assigned to items having similar properties. In the present disclosure, although the properties of items are used to provide class and similar item group information, the properties of the items used are not necessarily dependent on the essential properties of the above-described items. Accordingly, in the present disclosure, non-essential properties of items such as class and similar item group information may be arbitrarily defined.

Therefore, in the present disclosure, a class and a similar item group may be identification information for a set of one or more items having the same and similar essential properties. Alternatively, in the present disclosure, a class and a similar item group may be identification information for a set of one or more items having the same and similar arbitrary properties.

Alternatively, the class or similar item group may be a set of items in which a similarity between items calculated based on a distance between correlation vectors satisfies a preset condition. Here, the correlation vector may include correlation values between an arbitrary item and other items. Referring back to FIG. 2 , the correlation vector for item A may be (0, 1, 4, 5, 14, 7). Also, the correlation vector for the item E may be (14, 6, 22, 1, 0, 4). The processor 110 may determine items having the shortest distance between the correlation vectors as the items corresponding to the first item. The correlation vector may mean a frequency of designation of one item with another item. Accordingly, when the correlation vectors are similar (ie, when the distance between the correlation vectors is short), the two items can be regarded as similar items. Accordingly, since the correlation vector for similar items can be reflected in the list of recommended items, the protection of trademark rights can be further three-dimensionally promoted.

The processor 110 may give weights when increasing the correlation between items having different classes ( S120 ).

Non-essential attributes such as class and similar item group information for an item may be stored in the memory 120 and read by the processor 110 . Accordingly, when calculating the degree of correlation between the plurality of items, the processor 110 recognizes each of the plurality of items, and reads, if necessary, at least one or more class and similar item group information for each of the items from the memory 120 . can be recognised.

Specifically, non-essential attributes such as class and similar item group information for an item may be stored in the memory 120 and read by the processor 110 . Accordingly, when calculating the degree of correlation between the plurality of items, the processor 110 recognizes each of the plurality of items, and reads, if necessary, at least one or more class and similar item group information for each of the items from the memory 120 . can be recognised.

The processor 110 may determine whether the classes of the first item and the second item are the same, and when the classes are different, the processor 110 may assign a weight index to increase the degree of correlation between the first item and the second item.

Specifically, the processor 110 may determine the weight index by using whether the non-essential properties are the same, the similarity between the non-essential properties, and the like. Specifically, the processor 110 may recognize a measure of identity and similarity between non-essential attributes (ie, degree of similarity). The similarity between these non-essential attributes may be pre-stored in the memory 120 and read by the processor 110 . Alternatively, when the class or similar item group information is text information, the processor 110 performs a conventional calculation method of similarity between strings, such as Levenshtein Distance, Hamming Distance, Smith-Waterman, and Sørensen-Dice Coefficient, or a neural for text processing. The similarity between non-essential attributes can be calculated using a network-based word similarity technique. Alternatively, the processor 110 may calculate the similarity between information of a class or similar item group in the form of text information based on a neural network that calculates a similarity between meanings implied by non-essential properties of items.

Since the above description is only exemplary, the method of calculating the similarity between non-essential information, particularly a class and a group of similar items, should not be limited to the above-described example.

The processor 110 may calculate a weight index by using the similarity between the calculated non-essential attributes. As an example, the processor 110 may assign a higher weight as the non-essential properties are similar, and conversely assign a lower weight as the non-essential properties are different. Conversely, in order to recommend several items having different non-essential properties, the processor 110 may give a lower weight as the non-essential properties are similar, and may give a higher weight as the non-essential properties are different. As described above, the processor 110 may perform such a series of selections without direct instruction from the user. For example, when the user grants "multi-class selection", the processor 110 may assign a higher weight index as the non-essential properties are different based on this input. Furthermore, when the classes of at least two items among the plurality of first items selected by the user to receive the item recommendation are different, the processor 110 automatically recognizes this as "multi-class selection" and weights it as non-essential properties are different. indicators can be given high. Conversely, when the classes of the plurality of first items selected by the user to receive the item recommendation are all the same, the processor 110 automatically recognizes this as "single class selection", and gives a higher weight index as the non-essential properties are similar. You can do it.

Based on various similar methods, the processor 110 may calculate correlation and correlation data so as to generate an item recommendation list suitable for a user's needs.

9 is a flowchart illustrating a process in which a processor generates correlation data between items according to some embodiments of the present disclosure.

The processor 110 may generate a representative data group including one or more similar representative data (S130).

In some embodiments according to the present disclosure, representative data (related to an event) may include an event name representing the event, an image, a video, a thumbnail, a voice, and the like. Furthermore, the representative data may be multimedia data in which the event name, image, video, thumbnail, voice, and the like are combined. Since the above description is only an example of the type of representative data, the type of representative data is not limited thereto.

In the present disclosure, the processor 110 may generate a representative data group. As for the representative data group, the processor 110 may determine the degree of similarity between the representative data to generate the representative data group. For example, the processor 110 may determine the similarity between the representative data based on a neural network model that detects the similarity of images or words. When the determined similarity satisfies a preset criterion, the processor 110 may include representative data in one representative data group. Since the above description is only an example of a method for forming the representative data group, the method for generating the representative data group is not limited thereto.

It will be described with reference to FIG. 3 again. As illustrated in FIG. 3 , the representative data 400 may be a mark in the form of an image. Alternatively, the representative data 400 may be a brand name indicated by 'CHANEL'. In addition, the representative data may include both a mark and a name in the form of an image shown. Furthermore, the representative data may include only a core part of the data (hereinafter, referred to as a 'subject'). For example, referring to the representative data 400 shown in FIG. 3 , for some representative data, an additional figure or pattern is appended to the 'CHANEL' text. In this case, the processor 110 may recognize only the 'CHANEL' portion excluding the appended figures as the representative data 400 rather than recognizing the entire image of the corresponding mark as the representative data 400 .

Since this is only an example of the type of representative data, the type of representative data according to the present disclosure is not limited thereto.

The processor 110 may generate a representative data group and increase correlation between items corresponding to the representative data group. In the present disclosure, a representative data group may mean a set of similar representative data. Referring to FIG. 3 , the illustrated 'CHANEL' and similar marks may be grouped into one representative data group. The processor 110 may determine the similarity between the representative data to generate the representative data group. For example, the processor 110 may determine the similarity between the representative data based on a neural network model that detects the similarity of images or words. When the determined similarity satisfies a preset criterion, the processor 110 may include representative data in one representative data group.

The processor 110 may increase the correlation between the plurality of items corresponding to the representative data group ( S140 ).

The processor 110 may recognize items designated in each of the trademark applications included in the representative data group, and increase a correlation index between the items. In this case, the processor 110 may recognize the trademark applications included in the representative data group as one trademark application, and increase the relevance index by 1 for all combinations of each of the items.

Alternatively, the processor 110 may overlap the relevance index by reflecting the degree of similarity between the calculated representative data for each trademark application, regardless of whether the representative data group is generated. For example, when the similarity between the representative data of the first application and the representative data of the second application is 0.6, the processor 110 sets the relevance index by 0.6 in a combination between the items to which one or more items included in the second application are related. can increase

When a trademark applicant operates in a single industry, relates to a single brand, or wants overlapping protection for similar trademarks, it is highly likely that similar trademarks will be applied continuously for the same designated product. In this case, if the correlation is increased only for each application, there is a high possibility that the correlation value between designated products will be biased.

Accordingly, the correlation data 200 that meets the needs of the applicant may be generated according to which metadata is used to increase the correlation in the item recommendation method according to the present disclosure.

For example, if the applicant wants broad protection for trademark rights, increasing the correlation according to the applicant (or applicant code) can control the bias in the correlation value between designated products, so correlation for acquiring a wide range of trademark rights Data 200 may be generated.

Conversely, when the applicant desires overlapping protection for trademark rights, correlation data 200 suitable for overlapping protection of trademarks may be generated by increasing the correlation for each application.

This depends on how to evaluate the similarity of the representative data 400 when the same items are overlapped and designated together. For example, when the applicant desires overlapping protection for trademark rights, the processor 110 may determine to reflect the similarity in increasing the relevance index. Conversely, when the applicant wants broad protection for trademark rights, the processor 110 may determine to consider all applications included in the representative data group as a single application.

10 is a flowchart illustrating a process in which a processor generates a representative data group according to some embodiments of the present disclosure.

The processor 110 may calculate a degree of similarity for each of one or more representative data included in the representative data group (S131).

The processor 110 may generate a representative data group and increase correlation between items corresponding to the representative data group. In the present disclosure, a representative data group may mean a set of similar representative data. Referring to FIG. 3 , the illustrated 'CHANEL' and similar marks may be grouped into one representative data group. The processor 110 may determine the similarity between the representative data to generate the representative data group. For example, the processor 110 may determine the similarity between the representative data based on a neural network model that detects the similarity of images or words. When the determined similarity satisfies a preset criterion, the processor 110 may include representative data in one representative data group. The processor 110 may recognize items designated in each of the trademark applications included in the representative data group, and increase a correlation index between the items. In this case, the processor 110 may recognize the trademark applications included in the representative data group as one trademark application, and increase the relevance index by 1 for all combinations of each of the items.

The processor 110 may assign a weight corresponding to each of the one or more representative data based on the degree of similarity ( S132 ).

The processor 110 may generate a representative data group and increase correlation between items corresponding to the representative data group. In the present disclosure, a representative data group may mean a set of similar representative data. Referring to FIG. 3 , the illustrated 'CHANEL' and similar marks may be grouped into one representative data group. The processor 110 may determine the similarity between the representative data to generate the representative data group. For example, the processor 110 may determine the similarity between the representative data based on a neural network model that detects the similarity of images or words.

In this case, the processor 110 may recognize the trademark applications included in the representative data group as one trademark application, and increase the relevance index by 1 for all combinations of each of the items.

Alternatively, the processor 110 may overlap the relevance index by reflecting the degree of similarity between the calculated representative data for each trademark application, regardless of whether the representative data group is generated. For example, when the similarity between the representative data of the first application and the representative data of the second application is 0.6, the processor 110 sets the relevance index by 0.6 in a combination between the items to which one or more items included in the second application are related. can increase

Alternatively, when the degree of similarity between the representative data is applied when the degree of relevance is increased, the reciprocal number of the degree of similarity between the representative data may be reflected in the degree of relevance. That is, when the similarity between the representative data is 0.2, when the relevance index is increased, 5, which is the reciprocal of the similarity, is multiplied by the reciprocity index increase value 1 to increase 5. In this case, the amount of increase in the correlation between the trademark applications with low similarity between the representative data will be larger.

When a trademark applicant operates in a single industry, relates to a single brand, or wants overlapping protection for similar trademarks, it is highly likely that similar trademarks will be applied continuously for the same designated product. In this case, if the correlation is increased only for each application, there is a high possibility that the correlation value between designated products will be biased.

Accordingly, the correlation data 200 that meets the needs of the applicant may be generated according to which metadata is used to increase the correlation in the item recommendation method according to the present disclosure.

For example, if the applicant wants broad protection for trademark rights, increasing the correlation according to the applicant (or applicant code) can control the bias in the correlation value between designated products, so correlation for acquiring a wide range of trademark rights Data 200 may be generated.

Conversely, when the applicant desires overlapping protection for trademark rights, correlation data 200 suitable for overlapping protection of trademarks may be generated by increasing the correlation for each application.

This depends on how to evaluate the similarity of the representative data 400 when the same items are overlapped and designated together. For example, when the applicant desires overlapping protection for trademark rights, the processor 110 may determine to reflect the similarity in increasing the relevance index. Conversely, when the applicant wants broad protection for trademark rights, the processor 110 may determine to consider all applications included in the representative data group as a single application.

11 is a flowchart illustrating a process in which a processor performs a method of generating correlation data between items according to some embodiments of the present disclosure.

The processor 110 may determine one or more items having similar properties to an item to increase the correlation among a plurality of items included in the item database ( S150 ).

Thereafter, the processor 110 may increase the correlation with respect to one or more items having similar properties ( S160 ).

In the present disclosure, the item database may be a database in which information about an item is stored. For example, the item database may include information about the name of each item, essential properties and non-essential properties of each item.

Specifically, when it is desired to increase the correlation between item A and item B, the processor 110 may process as follows.

The processor 110 may recognize items having similar properties to item B from the item database. Thereafter, the processor 110 may increase the correlation between the item A and the item B and items having similar properties to the recognized item B.

The degree of similarity of any two items may be determined based on the similarity of their essential/non-essential attributes. The processor 110 may determine that the two items are similar when the degree of similarity between any two items satisfies a preset condition.

For example, the processor 110 may determine that items belonging to the same class or belonging to the same similar item group are similar. Alternatively, the processor 110 may determine the similar item by using the essential attribute of the first item. For example, with respect to the intrinsic attribute of the first item, it may be determined that the second item having the intrinsic attribute matching a certain ratio or more is an item similar to the first item. The processor 110 may determine an item similar to the first item based on a model using a neural network as shown in FIG. 5 or a conventional text similarity analysis algorithm such as Levenshtein Distance. The processor 110 may extract the determined similar items as one or more items corresponding to the first item.

Alternatively, one or more items extracted corresponding to the first item may be a set of items in which a distance between correlation vectors satisfies a preset condition. The correlation vector may be a vector expressing correlation values of an arbitrary item with one or more other items. Referring back to FIG. 2 , the correlation vector for item A may be (0, 1, 4, 5, 14, 7). Also, the correlation vector for the item E may be (14, 6, 22, 1, 0, 4). The processor 110 may determine items having the shortest distance between the first item and the correlation vector as the item corresponding to the first item.

The correlation vector may mean a frequency in which one item is related to another item in the same event. Accordingly, when the correlation vectors are similar (ie, when the distance between the correlation vectors is short), the two items can be regarded as similar items. Accordingly, since the correlation vector for similar items can be reflected in the list of recommended items, the protection of trademark rights can be further three-dimensionally promoted.

Alternatively, the processor 110 according to some embodiments of the present disclosure may extract one or more items corresponding to the first item based on the distance between the correlation vectors.

Here, the correlation vector may include correlation values between an arbitrary item and other items.

Accordingly, since the correlation vector for similar items can be reflected in the list of recommended items, the protection of trademark rights can be further three-dimensionally promoted.

In this case, the processor 110 may recognize one item most similar to item B.

In general, when a trademark application is made, it cannot be said that consideration is given to the attributes of all designated goods. Accordingly, omissions for similar designated products may occur. Accordingly, the correlation value may be distorted. To compensate for this, it is possible to find designated products similar to the designated products to be designated and to increase the degree of correlation and increase the degree of correlation together. Through this, it is possible to overcome the distortion of correlation caused by omission of designation in the original data.

12 is a flowchart illustrating a process in which a processor determines one or more items having similar attributes to an item to increase a correlation, according to some embodiments of the present disclosure.

The processor 110 may calculate the similarity between the item to be increased in relation to and one or more items having similar properties ( S151 ).

The degree of similarity of any two items may be determined based on the similarity of their essential/non-essential attributes. The processor 110 may determine that the two items are similar when the degree of similarity between any two items satisfies a preset condition.

For example, the processor 110 may determine that items belonging to the same class or belonging to the same similar item group are similar. Alternatively, the processor 110 may determine the similar item by using the essential attribute of the first item.

The processor 110 may assign a weight to each of one or more items having similar attributes based on the similarity ( S152 ).

The processor 110 may generate a weight by using the similarity. For example, the processor 110 may determine the similarity as a weight as it is. Alternatively, the processor 110 may determine the reciprocal of the similarity as a weight.

This depends on how to evaluate the similarity of the representative data 400 when the same items are overlapped and designated together. For example, when the applicant wants overlapping protection for trademark rights, the processor 110 may determine the similarity as a weight as it is. Conversely, when the applicant wants broad protection for trademark rights, the processor 110 may determine the reciprocal of the similarity as a weight.

13 is a flowchart illustrating a process in which a processor generates a list of recommended items according to some embodiments of the present disclosure.

The processor 110 may recognize correlation data related to the first item ( S310 ).

The processor 110 may recognize the class of the first item and the class of each of the one or more items having a correlation between the class and the first item ( S320 ).

The processor 110 may assign weights to one or more items having different classes from the first item (S330).

When an applicant desires multiple applications, items in the same class may be excluded when generating a list of recommended items by the above-described method. Accordingly, an appropriate list of recommended items may be generated and provided without an expert's intervention.
