Description

System and method for providing cross searching service of audiovisual information and contents information}

The present invention relates to a method and a system for providing a cross-search service of audiovisual information and content information. More particularly, the present invention relates to a method of providing audiovisual information and content information in association with a knowledge node connection structure having a graphic topology structure that defines associations between related words. The present invention relates to a method and a system for providing a cross search service.

Existing search system provides a search server simply search the search database by the search word received from the user to simply list the data in order. These search systems are designed for depth search on specific search terms, and simply list the search result information. Therefore, there is a limit that the user must arbitrarily grasp the relevance of each information included in the search result based on his intellectual ability.

Many users want to get various contents information through the search system. For example, users can access a search system on the Internet faster than newspapers or TVs to access the latest articles, and search for and browse the desired articles even if they do not go to the library. You can also access bulletin boards, read posts posted by other users, and retrieve reports written by other users on the same assignment. As such, users access relevant information by using the search function of the search system to obtain a large amount of content information in text form such as newspaper articles, articles, books, posts, reports, and the like.

In addition, in recent years, the demand for searching for audiovisual information such as multimedia, which is easier and more interesting, has been explosively increased. For example, a user may search for and watch a video such as a live or recorded program of a TV, a music video of a singer, a movie trailer, and the like through the Internet. In addition, images are searched to see faces of celebrities or sports players in question, and web maps are searched to find out the movement route before leaving for a specific place. In particular, in recent years, since individuals can easily create User Created Contents (UCC) such as videos, personally created UCCs create social issues, and in this case, users want to immediately search for and enjoy these UCCs. do.

As such, despite the rapid increase in the search demand for audiovisual information in addition to the content information search, the existing search system searches for the content information and the audiovisual information respectively, and takes the form of dividing each search result. have. For example, when a user enters a specific search term, the text information search result box may search for and list 'text information including the search term in the content', and the video search result suggestion may include Search for 'video' and list and search for 'image containing the search term in the title' in the image search result presentation box.

Since the existing search result presentation form presents content information and audiovisual information separately as a search result, it is difficult to grasp the relation between the searched content information and the searched audiovisual information.

Therefore, in order for the user to access other relevant audiovisual information after accessing the content information or to access other related content information after accessing the audiovisual information, the user must select specific information by himself, and the search system can Selecting specific content information or audiovisual information does not present relevant audiovisual information or content information. That is, the existing search system only presents content information and audiovisual information in response to a user's search request, and does not provide relevant audiovisual information and content information with respect to the content information and audiovisual information presented as a search result.

Therefore, in order for the user to obtain other information related to the information presented as a search result, the user had to infer a new search term that is relevant and input it. In other words, the search results presented by the existing search system depend on the user's intellectual ability to enter a suitable search word to the last, and cannot provide related information that the user cannot provide as a search word.

By using such existing search system, it is difficult for a user to expand the search results with relevant and relevant knowledge, which is inappropriate for creating new knowledge through assembling and combining information. In other words, a user using the existing search system can obtain content information and audiovisual information in a limited range, and has a lot of difficulty in expanding his or her knowledge based on the organic relevance of the content information and audiovisual information.

Accordingly, the present invention has been devised to solve the above problems, and is a three-dimensional and integrated knowledge acquisition and retrieval through cross-research of content information and audio-visual information in connection with a knowledge node connection structure in which correlations between individual data are defined. It is an object of the present invention to provide a method and system for providing a cross-search service of audiovisual information and content information linked to a knowledge node connection structure for enabling the same.

The knowledge node linkage structure used in the present invention defines a specific word as a core word, lists at least one related word derived according to the association from the core word, and configures the core word and each related word as one knowledge node. Refers to a collection of nodes in a graphical topology.

Here, the graphical topology is defined as the knowledge of several words, and the main or final relationship between words is expressed in geometric structure using figures and lines according to the importance of each word or the relationship between words.

As an example, the graphical topology may have a horizontal-vertical expansion structure as shown in FIG. 1.

Referring to FIG. 1, when a1 is defined as a key word, related words derived from a1 are a2, a3, and a4, and these a1, a2, a3, and a4 constitute one unit knowledge node connection structure. The unit knowledge node connection structure is indicated by a dotted line in FIG. 1. In addition, a3 is a related word of a1, but may be a new key word. In FIG. 1, related words including a3 as a key word are a5 and a6. Thus, a3, a5, and a6 may constitute another unit knowledge node connection structure. Similarly, the related word for a6 as a key word is a7, and a6 and a7 constitute another unit knowledge node connection structure. In this way, the unit knowledge node connection structure may be combined to form a combination knowledge node connection structure of a horizontal-vertical extension structure.

As another example, the graphical topological structure may have a concentric circular expansion structure as shown in FIG. 2.

Referring to FIG. 2, when a1 is defined as a key word, related words derived therefrom are a2 and a3, and a1, a2 and a3 constitute one unit knowledge node connection structure. Similarly, unit knowledge node linking structure with a1 as key word and a4 and a5 as related words, unit knowledge node linking structure with a1 as key word and a6, a7 and a8 as related words. Multiple unit knowledge node connection structures can be constructed. In this way, the unit knowledge node connection structure may be combined to form a combination knowledge node connection structure of concentric circular expansion structures.

As another example, the graphic topology may have branch extension structures as shown in FIG. 3.

Referring to FIG. 3, a unit knowledge node connection structure may be configured by using a1 as a key word and a2, a3, and a4 as related words, and a5 and a6 as related words using a2 as a key word. The unit knowledge node connection structure can be constructed. In addition, another unit knowledge node connection structure may be configured by using a1 as a core word and a7, a8, and a9 as related words. In this way, a plurality of unit knowledge node connection structures may be combined to form a combination knowledge node connection structure of branch extension structures.

Meanwhile, the embodiment of the graphic topology may be modified in addition to the above-described embodiments. Therefore, in the present invention, one knowledge is defined as several words, and the main or final relationship between the words is expressed in geometric structure using shapes and lines according to the importance of each word or the relationship between the words, and the plurality of words displayed as described above. The geometrical structure of the geometrical structure assembled in various forms will be collectively referred to as the graphical topology.

4 is a diagram illustrating a schematic configuration of a system 110 for providing a cross-search service for audiovisual information and content information linked to a knowledge node connection structure of a graphic topology according to an embodiment of the present invention.

Referring to FIG. 4, the cross-search service providing system 110 for audiovisual information and content information according to an embodiment of the present invention includes a knowledge node connection structure providing module 111, a knowledge node selecting module 112, and 1. And a vehicle information providing module 113, a cross-search information providing module 114, and a database 117. In addition, the cross-search service providing system 110 for the audiovisual information and the content information is connected to the user terminal 120 through the wired or wireless communication network 130 to transmit and receive various information and data from the user.

The knowledge node connection structure providing module 111 may include a knowledge node connection structure including at least one combination of content information, a knowledge node configuration word given priority, and a unit knowledge node connection structure of a graphic topology structure in which audiovisual information is linked. to provide.

Here, the knowledge node configuration word preferably includes a core word and at least one related word connected to the core word. At this time, it is preferable that the knowledge node connection structure is further connected with connection reason information of a core word and a related word. That is, while providing key words and related words in the knowledge node connection structure, it is possible to present specific information about the reason why the related words are connected to the key words.

Meanwhile, in the present invention, the priority means only an arbitrary order of receiving knowledge node configuration words when the knowledge node connection structure is generated, and does not necessarily mean that there is an objective dependency relationship between the knowledge node configuration words. For example, it does not necessarily mean that a related word that is relatively far from a key word in any knowledge node connection structure of a graphical topology structure is necessarily dependent on the related word that is closer to the key word.

The audiovisual information is knowledge information that can be acquired through vision or hearing. Preferably, the audiovisual information refers to at least one or more of a video, an image, music, and a web map.

The audiovisual information may be a URL or an audiovisual file for the audiovisual file. That is, the audiovisual information includes a URL for an audiovisual file stored in a predetermined server, a file storage provided in the database 117, or an audiovisual file stored in a mass storage medium provided separately from the database 117.

Similarly, the content information may be a URL for content or content data directly input by a user. That is, the content information includes a URL for content information stored in a predetermined server, a file storage provided in the database 117, or a content file stored in a mass storage medium provided separately from the database 117.

The audio-visual information or the content information may be in the form of a URL for each file by using an open API provided by an existing site such as YouTube or Google. The public API is an interface that allows users to search their own database of a public API provider by simply coding a program according to a protocol proposed by Google and others. Thus, a general individual can code a program that can freely search a database such as YouTube or Google and extract a URL of audiovisual information included in a search result. With this in mind, the present invention can provide the user with the use of audiovisual and content information resources from other websites that support public APIs.

In the present invention, the content information refers to a text-based web document, and does not particularly limit the inclusion of a link of audiovisual information in the content.

The unit knowledge node connection structure, as shown by the dotted lines in Figures 1 to 3, of the visualized knowledge consisting of a combination of a figure and a line based on one key word and at least one related word derived from the key word It is an implicit display method. In addition, a corresponding key word or related word is displayed as a letter on or around the figure constituting each knowledge node included in the unit knowledge node connection structure.

The combined knowledge node connection structure refers to a structure in which at least one unit knowledge node connection structure is combined as illustrated in FIGS. 1 to 3. Therefore, the combined knowledge node connection structure is a concept including both a unit knowledge node connection structure or two or more knowledge node connection structures combined.

The combined knowledge node connection structure may be generated by combining the unit knowledge node connection structure generated by the user or created by others. Alternatively, the combined knowledge node connection structure may be arbitrarily generated and stored in the database 117 by a service provider.

The knowledge node connection structure providing module 111 inquires the database 117 in response to a user's search request and provides the combined knowledge node connection structure stored in the database 117 to the user in a graphical topology.

5 is a diagram illustrating an embodiment of a screen in which the knowledge node connection structure providing module 111 according to the present invention outputs a plurality of combined knowledge node connection structures to the user terminal 120.

As shown in FIG. 5, when the user receives a search request from the user with the keyword 'apple', the knowledge node connection structure providing module 111 corresponds to a graphic topology of three combined knowledge node connection structures including 'apple' corresponding thereto. Output to the user terminal 120 in a structure. The location of the knowledge node containing the 'apple' is not particularly limited to the knowledge node of the core word or the knowledge node of the related word.

The combined knowledge node connection structure output as a result of the search includes a core word and a related word, a plurality of knowledge nodes corresponding to each of them, and a line represented according to the importance of each word (knowledge node) or the relationship between the words.

Meanwhile, in FIG. 5, the knowledge node connection structure providing module 111 outputs a plurality of combination knowledge node connection structures, but it is also possible to output one combination knowledge node connection structure.

The knowledge node selection module 112 receives one or more knowledge nodes from among the knowledge nodes existing in the combined knowledge node connection structure output by the knowledge node connection structure providing module 111. In this case, the user may select the knowledge node by clicking on the knowledge node with the mouse, placing the mouse over the corresponding knowledge node, or directly inputting a key word or a related word displayed on each knowledge node with a keyboard. However, the present invention is not limited by the specific selection method.

Meanwhile, when a plurality of combined knowledge node connection structures are output as shown in FIG. 5, the knowledge node selection module 112 receives a function of selecting a combination knowledge node connection structure of some of the outputted knowledge node connection structures from a user. It may further include.

The primary information providing module 113 identifies key words and / or related words corresponding to the knowledge nodes selected by the knowledge node selection module 112. In addition, the database 117 retrieves the unit knowledge node connection structure in which the identified core word and / or related words are assigned to the knowledge node. In addition, at least one content information or audiovisual information associated with the identified unit knowledge node connection structure is inquired from the database 117 and provided to the user terminal 120.

Preferably, the primary information providing module 113 lists and provides at least one piece of content information or audiovisual information to a user. Therefore, in this case, the user can collectively and collectively determine a plurality of content information or audiovisual information associated with the unit knowledge node connection structure.

In this case, the content information or audiovisual information may be configured as a link to content data or audiovisual data to be accessed. Therefore, the user can easily access the corresponding content data or audiovisual data by simply clicking a link.

In addition, when specific content information or specific audio-visual information is designated in the list, it is preferable that a cross search request is automatically made. For example, when the user selects specific content information or audiovisual information on the list, the cross-search information providing module 114 may receive the request as the cross-search request for the selected information is made while accessing the selected information. . As another example, the primary information providing module 113 may separately provide an interface such as a button for requesting a cross-search for each individual information while providing a list of content information or audiovisual information to the user. At this time, when a user clicks a specific button, it is assumed that a cross-search request for corresponding content information or audiovisual information is made. However, the present invention is not limited by this particular cross-search request method.

The list of content information or audiovisual information may further include information on knowledge node components of a unit knowledge node connection structure corresponding to each piece of content information or audiovisual information. That is, the content information list or the audiovisual information list may include, as node configuration word information, key words constituting each knowledge node, related words, and reasons for connection of related words.

On the other hand, the list includes both the form of selecting and continuously listing each piece of content information or audiovisual information, and the form that is output in the form of bulletin board.

FIG. 6 is a diagram illustrating a screen illustrating a first search result for audiovisual information provided prior to a cross search. The screen illustrated in FIG. 6 has a form in which video information is listed based on video information.

Referring to FIG. 6, the screen includes an interface for selecting a type of audiovisual information.

The interface is a tab menu. However, the present invention is not limited thereto.

The screen is a screen when a type of audiovisual information is selected as a video in the tab interface. In the case where a tab such as an image, music, or web map is selected, audiovisual information is output in a similar manner.

The screen provides a list of video information corresponding to a unit knowledge node connection structure including a knowledge node selected by a user. For example, the video information includes a video start screen and a link for executing a video. The user can click to play the video he / she wants. In this case, the video may be generated by executing a separate window.

In addition, as shown in FIG. 6, a cross search request button may be provided for each audiovisual information. Therefore, when a user clicks a specific button, a cross-search request for the clicked audiovisual information is made. However, this is only an example, and there is no separate button for cross-search request, and when a user clicks individual audiovisual information, the user can access the clicked information and make the cross-search request automatically. Examples are possible.

FIG. 7 illustrates another screen (bulletin board form) that may be provided when a type of audiovisual information is selected as a video in the tab menu. When the audiovisual information other than the video is selected, the screen provided only replaces the type of the audiovisual information, and the actual configuration of the screen is the same.

The screen allocates a row for each unit of knowledge node connection structure including the knowledge node selected by the user, and the meta information (core word, related word and reason for connection) of the unit knowledge node connection structure, title of the video, and video for each row. It includes a URL, a video launch link, and a cross search request button.

The screen can be identified at a glance because the associated video information, including the words constituting the knowledge node connection structure can be identified at a glance before the screen described above.

The URL of the video indicates an access path to the video corresponding to the corresponding knowledge node connection structure. The video execution link enables execution of a video corresponding to the corresponding knowledge node connection structure. The cross-search request button performs the same function as the cross-search request button provided on the screen described above.

8 is a diagram illustrating a screen illustrating a first search result for content information provided prior to a cross search.

As shown in FIG. 7, the screen of FIG. 8 allocates one row for each unit knowledge node connection structure including the knowledge node selected by the user. Each row includes meta information (core word, related word and reason for connection), title of content information, URL of content information, content information execution link, and cross-search request button of unit knowledge node connection structure.

The URL of the content information provides an access path to the content information corresponding to the corresponding knowledge node connection structure. The execution link enables execution of content information corresponding to the knowledge node connection structure.

In addition, the cross-search request button allows a user to request a cross-search for corresponding content information by clicking a specific button. In this case, the cross search request button may be separately provided for each type of audiovisual information such as a video request button, an image request button, a music request button, and a web map request button as shown in FIG. 8. However, it is also possible to have one cross-search request button.

Meanwhile, the present invention is not limited to the specific interface of the screen on which the content information and the audiovisual information as shown in FIGS. 6 to 8 are provided.

The cross-search information providing module 114 receives a cross-search request based on specific content information or specific audio-visual information in the content information or audio-visual information provided by the primary information providing module 113. Here, as described above, various embodiments may exist in a method of receiving a cross search request.

Then, the cross-search information providing module 114 includes audiovisual information corresponding to the unit knowledge node connection structure in which the same content information and the same content information are linked, or unit knowledge node in which the same audiovisual information is linked to the specific audiovisual information. Provide content information corresponding to the connection structure.

For example, when a user requests a cross search for specific content information among the content information or audiovisual information provided by the primary information providing module 113, the cross-search information providing module 114 may have the same content as the corresponding content information. The unit knowledge node connection structure to which the information is linked is queried to provide audiovisual information corresponding to the retrieved unit knowledge node connection structure (ie, stored in association) as cross-search information.

If the user requests a cross search for specific audiovisual information among the information provided by the primary information providing module 113, the cross-search information providing module 114 is a unit to which the same audiovisual information as the corresponding audiovisual information is linked. The knowledge node connection structure is queried to provide content information corresponding to the retrieved unit knowledge node connection structure as cross search information.

Inquire a node connection structure. Accordingly, the cross-search information providing module 114 finds unit knowledge node connection structures 103, 105, and 107 including p3 as content information. Then, the user is provided with audiovisual information corresponding to the found unit knowledge node connection structure 103, 105, and 107. Therefore, q3 and q7 as audiovisual information corresponding to the unit knowledge node connection structure 103, q3, q6 and q8 as audiovisual information corresponding to the unit knowledge node connection structure 105, q1, as audiovisual information corresponding to the unit knowledge node connection structure 107; Provide q9, q10 to the user.

According to the above embodiment, not only the content information p1, p2, p3 and p4 and the audiovisual information q1, q2 and q7 are primarily provided to the user in response to the selection of the knowledge node, but also the cross-search is associated with the content information p3. Audiovisual information q1, q3, q6, q7, q8, q9 and q10 are provided secondarily. That is, the audiovisual information initially provided to the user is q1, q2 and q7, but the audiovisual information q3, q6, q8, q9 and q10 are further provided as a cross-search result for p3.

If, in the above embodiment, the unit knowledge node connection structure 101 and 106 are inquired by the primary information providing module 113, the audiovisual information is provided among the content information p1, p2, p3 and p4 and the audiovisual information q1, q2 and q7 provided. When q7 is selected and a cross-search is requested, the cross-search information providing module 114 queries the unit knowledge node connection structure associated with q7. Accordingly, the cross-search information providing module 114 finds unit knowledge node connection structures 102 and 103 including q7 as audiovisual information. Then, content information corresponding to the retrieved unit knowledge node connection structure 102 and 103 is provided to the user. Accordingly, the cross-search information providing module 114 provides p5, p7 and p8 as content information corresponding to the unit knowledge node connection structure 102 and p3 and p6 as audiovisual information corresponding to the unit knowledge node connection structure 103. .

Therefore, in addition to providing the user with the content information p1, p2, p3 and p4 and the audiovisual information q1, q2 and q7 in response to the knowledge node selection, the content information p5, p6, p7 and p8 by cross-search. This is further provided. In this case, q3 and q4 may be further provided as audiovisual information corresponding to the unit knowledge node connection structures 102 and 103.
