Method for providing contents and apparatus thereof

The present invention relates to a method and apparatus for providing content, and more particularly, to a method and apparatus for selecting and providing content.

Recently, with the development of wireless communication technology, technologies for receiving various services using a mobile terminal have emerged. In particular, service technologies for providing content desired by a user to a mobile terminal have been proposed. For example, a service that provides learning contents for learners or tourism contents for travelers is included.

However, the proposed techniques have limitations in providing content according to the location of the mobile terminal which is determined by identifying the location of the mobile terminal. In other words, it does not reflect the complex and diverse environment of the user, and it is difficult to provide the content desired by the user in a timely manner since the selected content is provided based only on the location information.

On the other hand, the conventional content providing method is a method for providing the content according to the user's location information in advance to the mobile terminal at a location connected to the specified content. For example, if the user is located in a particular museum, the museum provides the user with museum information that matches the previously stored specific museum. Accordingly, the content provided to the mobile terminal is fixed to provide the user with repeated content or monotonous content. Therefore, there is a problem that the user easily loses interest or deteriorates interest.

An object of the present invention is to provide a content providing method and apparatus for providing customized content to a mobile terminal according to various environments in which the mobile terminal is located.

Accordingly, the present invention proposes a content providing method and apparatus for providing customized content selected through a real-time search to a mobile terminal.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention; In the following description of the present invention, if it is determined that detailed descriptions of related well-known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to intention or custom of a user or an operator. Therefore, the definition should be made based on the contents throughout the specification.

1 is a block diagram of a content providing device 1 according to a preferred embodiment of the present invention.

According to FIG. 1, the content providing device 1 includes a mobile terminal 10 and a server 20.

In the content providing device 1 of the present invention, the server 20 may search for and provide, in real time, customized content suitable for an environment where a user is located through wireless communication with the mobile terminal 10. That is, when the mobile terminal 10 requests the content from the server 20, the server 20 may select content suitable for the user's situation through real-time search using the search word and transmit the content to the mobile terminal 10.

Meanwhile, the server 20 includes a collector 200, a generator 210, and a content selector 220. Furthermore, the storage unit 230 and the content providing unit 240 may further include. In this case, the server 20 may include a collection unit 200, a generation unit 210, a content selection unit 220, a storage unit 230, and a content providing unit 240 in a separate server form. It may be provided in the form of an integrated server.

The collection unit 200 of the server 20 collects contextual information derived based on the sensing information in response to a content providing request including the sensing information detected through the mobile terminal 10.

At this time, the sensing information detected through the mobile terminal 10 includes all the information that can be detected through the sensor of the mobile terminal 10 including temperature, light quantity, humidity, noise level, UV index, RFID information as well as basic location information. It is desirable to.

Meanwhile, the derived situation information is information collected based on sensing information detected through the mobile terminal 10. For example, the situation information may be weather, traffic conditions, event information, or item information of an area where the mobile terminal 10 is located.

In more detail, the situation information may be information received from the outside. For example, based on the location information detected by the mobile terminal 10, it is possible to obtain weather information including temperature, humidity, wind speed, etc. of the region from the Meteorological Agency server. Alternatively, traffic situation information or map information of the area may be obtained from the police agency server.

Furthermore, the situation information collected by the server 20 may be user information of the mobile terminal 10. For example, the user's schedule, anniversary, and appointment information may be included. Alternatively, the information may be content usage history information of the user. On the other hand, the situation information that can be collected by the server 20 preferably includes all the information that can be obtained in accordance with the development of the technology in addition to the above information.

In summary, as the server 20 collects various contextual information, various kinds of information suitable for the environment in which the user is located may be provided, and thus, the mobile terminal 10 may provide customized content for each situation of the user.

Meanwhile, the generator 210 generates keyword information for real-time content search using context information collected through the collector 200 and sensing information detected through the mobile terminal 10. In this case, it is preferable to use a search word generation table in which search terms for context information and sensing information are mapped. The search word generation table may be stored in the storage 230. In this case, the search word generation table is data that is pre-set so that the server 20 can search the contents in real time using the search word of the keyword information. A detailed description of the search word generation table will be described later with reference to FIG. 5.

The content selector 220 selects content to be provided to the mobile terminal 10 through real-time search using keyword information generated by the generator 210. Here, the final content to be provided to the mobile terminal 10 may be selected by calculating the relevance according to the weight of the keyword information about the content. A detailed description of the content selection method will be described later with reference to FIG. 3.

The content provider 240 may provide the content selected by the content selector 220 to the mobile terminal 10, and the storage 230 may store a search word generation table.

Hereinafter, a method of providing content to the mobile terminal 10 of the server 20 will be described in detail with reference to FIGS. 2 and 3.

2 is a flowchart illustrating a content providing method according to a preferred embodiment of the present invention.

According to FIG. 2, the server 20 receives a content providing request from the mobile terminal 10 (S100). In this case, the mobile terminal 10 may transmit the sensing information detected by itself to the server 20 together with the content request. Then, the server 20 collects the derived situation information by using the sensing information of the mobile terminal 10. The derived situation information may be additional information including weather, traffic conditions, goods status, or the like, and user information of the mobile terminal 10.

Meanwhile, the server 20 generates keyword information by using the collected situation information and the detected situation information of the mobile terminal 10 (S110). This is to enable real-time search of content using keyword information generated by the server 20. Here, the keyword information may be set in advance in a form in which search terms for context information and sensing information are mapped.

Subsequently, the server 20 selects content to be provided to the mobile terminal through real-time search using the generated keyword information (S120), and provides the selected content to the mobile terminal 10 (S130).

Meanwhile, the mobile terminal 10 may transmit the feedback information according to the used content to the server 20 after using the provided content. At this time, the server 20 receives the feedback information from the mobile terminal 10 and reflects the content selection to be provided to the mobile terminal 10 (S140).

In more detail, the server 20 may update the personal information including the user's content usage history or preference through the feedback information. Accordingly, various content services can be provided to the user based on the updated personal information.

For example, if it is determined that the content preference is high based on feedback information received from the mobile terminal 10 when the server 20 selects the content, it is preferable to select the content with high preference even if the content is low in relevance. Do.

As another example, if the content is highly related but there are a lot of content usage histories, the server 20 may not select the content with a lot of content usage histories.

3 is a flowchart illustrating a content selection method according to a preferred embodiment of the present invention.

Referring to FIG. 3, the server 20 may select at least one content through a real-time search using keyword information generated through a search word generation table (S200). In this case, a degree of relevance to a search word for at least one selected content may be obtained. Such relevance can be calculated through a method using absolute relevance or a method using relative relevance.

For example, the method using absolute relevance is a method of measuring absolute relevance of a search word for at least one selected content. For example, if a search word is included in one content, the relevance may be set to 100%, otherwise the relevance may be set to 0%.

As another example, a method of calculating relevance using relative relevance is a method of sorting according to similarity with a search word for at least one selected content. For example, the relevance may be measured according to the similarity measured through the text search algorithm for the content. The higher the similarity, the higher the relevance.

On the other hand, when measuring the relevance using the relative relevance, it is possible to calculate the relevance applying the weight of the keyword information for the selected at least one content (S210). That is, a predetermined weight may be given to each of the search terms of the keyword information, and the related relevances to which the weight is applied may be summed. In this case, it is preferable to select the content with the highest sum as the content to be provided to the terminal (S220).

4 is a reference diagram for explaining a keyword information generation process using a search word generation table according to an exemplary embodiment of the present invention.

According to FIG. 4, in the search word generation table, search terms corresponding to each situation of the sensing information detected through the mobile terminal 10 and the situation information collected by the server 20 are mapped.

For example, when information for generating keyword information is 'temperature', as shown in FIG. 4, when the temperature is 'between 14 degrees and 33 degrees', the generated search term may be 'hot', and the temperature may be '7 degrees ~'. The search term generated when it is between 13 degrees' may be 'cool'. In addition, the generated search word may be one, or may be multiple. For example, when the temperature is '0 degrees or less', the search term may be a plurality of words such as 'cold', 'ice', or 'winter'.

Meanwhile, at least one search word may be generated using the search word generation table as other information detected by the mobile terminal 10 or collected by the server 20.

For example, when the information detected or collected as shown in FIG. 4 is 'temperature', 'traffic' and 'scheduled', for example, the environment in which the user is located has a temperature of '26 degrees 'and the average speed of the vehicle is' 25km ", and if the date is" July 14, "you can create search terms" hot, "" delayed, "and" birthday "through the query generation table. The generated search word is a criterion for the server 20 to select content to be provided to the mobile terminal 10 through a content search in real time.

Meanwhile, the search word generation table for generating the search word is preferably set in advance and stored in the server 20.

5 is a reference diagram for describing a relevance of keyword information for content according to a preferred embodiment of the present invention.

According to FIG. 5, the server 20 may select at least one content through real-time search using the generated keyword information. Therefore, through the real-time search, it is possible to timely transmit the customized content suitable for the user's environment to the mobile terminal 10.

The relevance of at least one selected content may be calculated. When calculating the relevance as shown in FIG. 5 using the example search word in FIG. 4, the relevance corresponding to the 'hot' of the temperature, the 'delay' of the traffic, and the 'birthday' of the schedule can be obtained.

For example, as shown in FIG. 5, the first content has a 10% relevance to 'cover', a 0% relevance to 'lazy', and a 3% relevance to 'birthday'. In this case, the higher the similarity through real-time search, the higher the relevance.

6 is a reference diagram for explaining a process of calculating a relevance by applying weights to keyword information of content according to an exemplary embodiment of the present invention.

According to FIG. 6, a final relevance may be obtained by applying weights to keyword information of at least one content.

For example, when the weight is applied to the relation obtained in FIG. 5, the weights of the 'weather', 'traffic', and 'schedule' information may be 5, 30, and 40, respectively. In this case, the weights are applied to each keyword and summed to obtain a final relevance. For example, in the case of the first content, the final relevance may be (10 * 5) + (0 * 30) + (3 * 40) = 170.

In this way, if the final relevance of the remaining content is obtained, the content having the highest relevance can be selected. For example, as shown in FIG. 6, the fourth content obtained with 315 may be selected as the content to be provided to the mobile terminal 10.

7 is a flowchart illustrating a content selection method according to an embodiment of the present invention.

According to FIG. 7, the mobile terminal 10 detects sensing information through a sensor (S300). At this time, the server 20 is requested to provide content including the sensing information sensed by the mobile terminal 10 (S310). Then, the server 20 collects contextual information derived based on the sensing information according to the content providing request of the mobile terminal 10 (S320). The derived situation information may be additional information that can variously access the environment in which the user of the mobile terminal 10 is located.

The server 20 collecting the situation information generates keyword information for real-time content search using the situation information and the sensing information (S330). Here, the keyword information may be generated using a search word generation table to which search terms for context information and sensing information are mapped.

On the other hand, the server 20 selects the content to be provided to the mobile terminal through the real-time search of the content using the keyword information (S340). In this case, the final content may be selected according to the relevance and weight. Then, the server 20 may provide the selected content to the mobile terminal 10 (S350).

Furthermore, the server 20 may receive feedback information on the content provided from the mobile terminal 10 which received the selected content (S360). In this case, the feedback information may be content usage history information or preference. Accordingly, the server 20 receiving the feedback information may reflect the received feedback information in selecting content to be provided to the mobile terminal 10.

For example, if there is already provided content in the environment where the user is located through the content usage history, other content may be provided to the mobile terminal 10. Therefore, the user may be provided with new content instead of bad content. Accordingly, when the user is a learner, the learning effect of the user can be enhanced. Or if the user is sightseeing, the user can get greater satisfaction with the trip.

As another example, when receiving feedback information that a user's preference or interest is high for a specific content, the corresponding content may be provided to the user when the content is selected.

Hereinafter, various embodiments available through the content providing method according to the present invention will be described with reference to FIGS. 8 and 9.

Through the content providing method according to an embodiment of the present invention, it is possible to provide learning content to learners, provide travel content to tourists, or provide content to buyers.

8 is an exemplary view showing content provision of a server according to an embodiment of the present invention.

According to FIG. 8, in the case of taking the English learning content, when the user is located in the airfield, the word 'airport' may be provided to the mobile terminal 10 through the map information. In contrast, when the user is located in the sports stadium, the word 'stadium' may be provided to the mobile terminal 10.

If FIG. 8 is content information that can be provided based on location information of the mobile terminal 10, FIG. 9 is content information that can be provided to the mobile terminal 10 based on weather information.

For example, when it rains, the word 'rainy' may be provided to the mobile terminal 10. In contrast, when the weather is clear, the word 'sunny' may be provided to the mobile terminal 10.

Meanwhile, FIGS. 8 and 9 are the simplest examples that can be implemented by the present invention, and the present invention may be embodied to include all the various types of embodiments widely used in the art in addition to the above-described examples. Do.

In summary, according to an embodiment of the present invention, the sensing information through the sensor of the mobile terminal 10 and the context information collected by the server 20 may be combined to provide customized content suitable for various environments of the user.

In addition, by using a search word generation table in which search terms for each situation information and sensing information are mapped, at least one content may be provided in real time to provide timely content suitable for an environment in which the user is located.
