Next, referring to FIG. 2, a process of constructing a search database according to an embodiment of the present invention will be described. 2 is a diagram showing a process of building a search database according to an embodiment of the present invention.

Referring to FIG. 2, in step 201, the controller 110 executes a service application according to a user request, and displays an application screen including various service contents according to the execution of the service application through the display panel of the touch screen 190. . The service application may be various SNS applications, location-based service applications, and media service applications.

The user may input a preference action for the displayed service content through the touch screen 190 or another user interface according to his or her preference. The preference action may include an action representing a user's preference for the service content, an action representing the user's use of the service content, or an action using the service content to create a new content. For example, the preference action may be an action corresponding to recommendation, sharing, empathy, or scrap for service content. Alternatively, the preference action may be an action using a location-based service provided by an application.

When the controller 110 detects in step 203 that a user preference action has occurred while displaying the application screen including service content according to the execution of the service application, the process proceeds to step 205.

In step 205, the controller 110 analyzes the service content corresponding to the user preference action to generate a keyword tag. The keyword tag is a keyword indicating service content, and may be information indicating a location, a title, a name, and other related information according to the type of service content. For example, if the service content is content provided by a location-based service, the keyword tag may be a place name, place, building, business name, or the like. As another example, if the service content is a video, the keyword tag may be the title of the video. Alternatively, if the service content is a movie introduction, the keyword tag may be a movie title. As another example, when a ticket is reserved in the ticket reservation application, the title of a program corresponding to the ticket may be a keyword tag.

When the keyword tag is generated, the control unit 110 generates link information corresponding to the service content in step 207. The link information is information necessary to provide service content to a user, and may include identification information of a service application related to the service content, and connection information necessary to load an application screen including the service content after executing the service application.

For example, if the service content is content provided by a location-based service, link information required to load an application screen indicating map information for the service content or an application screen providing detailed description of the service content will be included in the link information. I can. As another example, if the service content is a video, the link information may include connection information required to connect an application screen on which the video can be played. As another example, if the service content is a ticket, the link information may include connection information required to display an application screen providing guide information on a program corresponding to the ticket.

When the link information generation is completed, the control unit 110 matches the keyword tag and the link information in step 209 and stores it in the search database.

In FIG. 2 described above, it has been described that the link information is generated after the keyword tag is generated, but the order of generating the keyword tag and link information is not limited to the above description. Next, referring to FIG. 3, a process of searching for a keyword using a search database constructed according to the process of FIG. 2 will be described. 3 is a diagram illustrating a process in which a keyword search is performed during execution of a service application according to an embodiment of the present invention. 3, in step 301, the controller 110 executes a service application according to a user request. Keyword search can be applied to various types of service applications. For example, it can be applied to text-based applications or media applications.

The text-based application is an application that is executed based on text input by a user, and may include, for example, a text service application, a chat application, a memo application, a schedule registration application, an instant messaging service application, and an SNS application. The media application is an application that enables media search, playback, and editing. Media includes music, video, movies, photos, audio files, broadcasts, and e-books. In addition, examples of the media application may be a photo album application, a music playback application, a video application, and an e-book application.

After the service application is executed, the controller 110 displays text according to the user input in step 303. Further, the controller 110 compares the text displayed in step 305 with a plurality of keyword tags stored in the search database to check whether there is a matching text. As a result of the verification, if there is a matching text, the control unit 110 proceeds to step 307 to determine the text as a keyword, and sets the text as a keyword. Accordingly, the control unit 110 changes the display of the text in order to allow the user to visually distinguish that the text is a keyword. For example, the text may be highlighted and displayed. Alternatively, the text may be displayed in a font different from other texts.

In addition, the controller 110 searches for link information corresponding to a keyword, constructs an application list, and links to the keyword by using application identification information included in the searched link information. The application list includes the name of at least one application. In some cases, user actions on the same service content may occur in different applications. Accordingly, a plurality of link information may exist in the search database corresponding to one keyword tag.

Thereafter, if there is an input for selecting a keyword from the user in step 309, the control unit 110 proceeds to step 311 to display a list of applications related to the keyword. The user can select a desired application from the displayed application list.

When the user selects an application, the controller 110 executes the application using link information including identification information of the application selected in step 313. In addition, the control unit 110 loads and displays a service content screen related to a keyword by using connection information included in the link information.

The process of constructing a search database by generating keyword tag and link information according to the execution of the Foursquare application and the process of providing the search result will be described as an example.

When the Foursquare application is executed, the current location is detected, and a list of nearby attractions, shopping malls, buildings, restaurants, theaters, etc. is displayed on the application screen based on the current location. The user may select any one of the items in the list, for example, restaurant A, and select and input a check-in for leaving a record that he is located in the selected item. When a check-in input occurs, the control unit 110 determines that a preference action has occurred. Accordingly, the control unit 110 generates restaurant A as a keyword tag. In addition, link information including identification information of the Foursquare application and connection information required to display the application screen including content guiding the restaurant A where the user checked in is generated. Thereafter, the control unit 110 matches the keyword tag and the link information and stores it in the search database.

Thereafter, if the user wants to register an appointment in restaurant A on a specific date in the schedule application of the digital device 100, the user will input an execution request for the schedule application. Accordingly, the control unit 110 of the digital device 100 executes the schedule application. Further, in response to a user input, the controller 110 may sequentially display a text string of 5 o'clock appointment at restaurant A on the display panel of the touch screen 190.

The control unit 110 compares the input text string and the keyword tag in real time. Accordingly, when the input of the text restaurant A is completed, the controller 110 may detect the keyword tag restaurant A in the search database. When a keyword tag is detected, the control unit 110 determines the input text restaurant A as a keyword, and displays the text restaurant A by highlighting it or changing the font.

And the control unit 110 detects the identification information of the Foursquare application from the link information corresponding to the restaurant A, and constructs an application list. In addition, when there is an input for selecting the keyword restaurant A from the user, the controller 110 displays an application list, that is, four square, by overlapping it. Thereafter, when there is an input for selecting the Four Square from the user, the controller 110 executes the Four Square application. In addition, the application screen including content guiding the restaurant A is displayed by using the connection information corresponding to the restaurant A and included in the link information including the Foursquare application identifier.

As another example, a process of constructing a search database by generating keyword tag and link information according to execution of a Facebook application and a process of providing a search result will be described as follows.

While the Facebook application is running, the user can input a recommended action for the singer Tom's music video. Accordingly, the controller 110 may determine that the preference action for the music video video of the singer tom has occurred, and may generate a title of the music video, for example, today as a keyword tag. Additionally, the control unit 110 may generate tom as a keyword tag. In addition, the control unit 110 generates connection information for linking a page providing today's music video video in the Facebook application and link information including identification information of the Facebook application. The controller 110 matches the keyword tag today with link information and stores it in a search database. In addition, the controller 110 may match the singer's name, that is, tom and link information, and store it in the search database.

Thereafter, the user can refer to the today's music video video of the singer tom during a text message conversation with another user. In other words, while the text message application is running, the user may input the text today into the digital device 100.

Accordingly, when the input of the text “today” is completed, the controller 110 may detect a keyword tag “today” from the search database. When a keyword tag is detected, the controller 110 determines the input text today as a keyword, and displays the text today by highlighting it or changing the font.

In addition, the control unit 110 detects identification information of a Facebook application from link information corresponding to today, and constructs an application list. And, if there is an input for selecting today from the user, the control unit 110 displays the application list, that is, Facebook overlapping. Thereafter, when there is an input for selecting a Facebook from the user, the controller 110 executes the Facebook application. And, corresponding to today, by using the connection information included in the link information including the Facebook application identifier, the application screen in which the today music video video is provided is displayed.

Next, with reference to Figs. 4 and 5, an example of classifying a type of keyword tag and providing a search result in a different manner according to the type of keyword tag according to another embodiment of the present invention will be described. In the embodiment shown in FIGS. 4 and 5, keyword tags generated in association with media content are classified and stored as media keywords, and a search result corresponding to the media keyword is provided in a different manner from that of other keywords.

First, referring to FIG. 4, a process of constructing a search database will be described when service content for which a user takes a preference action is location information provided by a location-based service or media content according to an embodiment of the present invention. In the embodiment of FIG. 4, when the service content is content provided by a location-based service, it is assumed that information indicating that a keyword tag corresponding to the content is a location keyword is additionally included in the link information. In addition, when the service content is a media content, it is assumed that information indicating that a kiweed tag corresponding to the media content is a media keyword is additionally included in the link information.

Referring to FIG. 4, in step 401, the controller 110 executes a service application and displays a corresponding service content screen on the display panel of the touch screen 190. In this case, the service content may be content including location information or media content. In a state in which the service application is running, the controller 110 detects an input of location information or a preference action for media content from a user in step 403. The service application may be an SNS application, a map-based application, a location-based service application, and a media application.

For example, when a running SNS application provides service content based on the current location of the device 100, and the user inputs an action using the provided location-based service content, the controller 110 It can be detected as a preference action input. As a specific example, when an SNS application provides a service for entering a memo along with a log record or check-in record for the current location of the device 100, and the user selects and uses such a service, the controller 110 provides location information It can be determined that the preference action input for is occurred. For example, this may be a “location check-in service” or “four square application” of the “Facebook application.” As another example, the SNS application checks nearby restaurants or attractions based on the current location of the device 100. When a service capable of being provided and a user selects such a service and selects a specific restaurant or attraction, the controller 110 may determine that a preference action input for location information has occurred.

As another example, in a map-based application, when a user searches for a specific location, for example, a place, place name, attraction, building, business place, etc., and registers the searched location as a preferred location, the control unit 110 It can be determined that an action input has occurred.

As an example of inputting a preference action for media content, when registering information related to preferred media content in a user profile of an SNS application, the controller 110 may determine that a preference action input for the media content has occurred. Media content may be music, movies, music videos, video content, television programs, books, exhibitions, and the like.

Alternatively, when a preference (like, recommendation, fun, sharing, empathy, scrap, etc.) for a specific media content is input during execution of the SNS application, the controller 110 may determine that a preference action input for the media content has occurred.

Returning to FIG. 4, the control unit 110 generates a keyword tag for the media content or location information for which the preference action input is confirmed in step 405.

For example, when a preference action input for location information is detected, a location keyword tag corresponding to the location information is generated. As a specific example, the current location of the device 100 detected during execution of the SNS application is "Seoul Station", and the SNS application provides a service that can store log records for "Seoul Station", and the user inputs an action using such a service. If there is, the controller 110 generates a keyword tag "Seoul Station". Alternatively, if the current location of the device 100 detected during execution of the SNS application is "Seoul Station", and the SNS application provides a specific service using "Seoul Station", and the user inputs an action using such a service, the controller 110 Create a keyword tag of "Seoul Station". The location keyword tag may be a name related to a corresponding location, for example, a name of a place, a name of a building, a name of a business place, etc. according to an embodiment of the present invention.

As another example, when a preference action input for media content is detected, a media keyword tag corresponding to the media content is generated. As a specific example, the name of the media content registered as the preferred content in the user profile of the SNS application or the name of a person related to the media content may be a media keyword tag. In other words, a title of a music album, a title of music, a title of a movie, a title of a book, a title of an exhibition, a title of a television program, a name of an actor, a name of a singer, a name of an artist, etc. may be media keywords.

Alternatively, when a preference (like, recommendation, fun, etc.) for a specific media content is input while the SNS application is running, the control unit 110 generates a name related to the media content, an artist name, etc. as a media keyword tag.

Alternatively, if there is media content uploaded by the user while the SNS application is running, the controller 110 generates a name related to the media content, an artist's name, etc. as a media keyword tag.

4, after generating the keyword tag, the controller 110 associates the keyword tag generated in step 407 with the link information corresponding to the keyword tag and stores it in the search database.

If the keyword tag is a location keyword tag, the link information links information indicating that the keyword tag is a location keyword, identification information of the service application related to the keyword tag, and the service screen provided by the service application in relation to the keyword tag. It contains the necessary connection information.

For example, when an SNS application provides a specific service related to the current location of the device 100 and the user inputs an action using a specific service, the SNS application displays a service screen related to the specific service on the device 100 . The link information includes information necessary to request the SNS application to display such a service screen. As a specific example, the current location of the device 100 detected during execution of the SNS application is "Seoul Station", and the SNS application provides a service that can store log records for "Seoul Station", and the user inputs an action using such a service. If present, a detailed information screen related to "Seoul Station" is displayed on the device 100. In this case, the location keyword tag becomes "Seoul Station", and the link information related to "Seoul Station" includes identification information of the corresponding SNS application and connection information necessary to request to display the detailed information screen related to "Seoul Station" by the SNS application. do.

In addition, when the keyword tag is a media keyword tag, the link information includes information indicating that the keyword tag is a media keyword, identification information of an application related to the keyword tag, and connection information for loading the corresponding media content.

Each time the service application is executed, a search database may be built through the above process.

5 illustrates a process of searching for a keyword while executing a text-based application according to an embodiment of the present invention. The text-based application is an application that is executed based on text input by a user, and may include, for example, a text service application, a chat application, a memo application, and a schedule registration application. In the embodiment of FIG. 5, when a keyword tag is identified as a media keyword, it is assumed that a recommendation list related to the keyword tag is constructed and provided.

Referring to FIG. 5, the control unit 110 executes a text-based application in step 501. And while the text-based application is running, the control unit 110 detects a text corresponding to a keyword tag from among texts input from the user in step 503. In other words, it is detected whether text matching the keyword tag stored in the search database is input by the user.

In step 505, the control unit 110 highlights the text corresponding to the keyword tag and displays it as a keyword, so that the user can know that the keyword can use the search database.

Thereafter, if there is a selection input for a keyword from the user in step 507, the controller 110 checks link information of the keyword tag. If it is a location keyword as a result of checking, in step 509, a list of service applications related to the keyword is displayed. A plurality of service applications may be installed on the user digital device 100, and accordingly, a plurality of identical keyword tags may exist. However, link information of each of the same plurality of keyword tags may be different. Accordingly, there may be a plurality of service applications provided corresponding to the keyword selected by the user.

In step 511, the controller 110 refers to link information corresponding to the service application selected by the user from among the displayed service applications, and displays a result screen accordingly.

In other words, if the keyword tag corresponding to the keyword is a location keyword tag, the controller 110 drives the service application selected by the user using the keyword tag link information and displays a service screen related to the keyword tag.

Then, as a result of checking in step 507, if the keyword corresponds to the media keyword tag, the control unit 110 proceeds to step 513 to construct and display a recommendation list using the media keyword. In other words, the controller 110 may drive a predetermined media service application, search for related media content using media keywords, and display the search result as a recommendation list. The specific media service application may be an application in which media content can be purchased.

Next, referring to FIG. 6, an example of automatically searching for media content preferred by a user and providing it to a user when a media application is executed will be described according to another embodiment of the present invention. 6 illustrates an operation process of the controller 110 when executing a media application according to an embodiment of the present invention. The media application is an application that can play, view, or purchase media content, and may be, for example, a photo application, a video playback application, and a music playback application.

In step 601, if there is a request to execute a media application, the controller 110 detects a media keyword from the search database in step 603. Then, in step 605, a predetermined media service application is driven, and related media content is searched for using a media keyword. Thereafter, in step 607, the search result is displayed as a recommendation list. The specific media service application may be an application in which media content can be purchased.

7 shows a case in which a location keyword tag "COEX" is detected while executing a text message application, which is a text-based application. When the location keyword tag “COEX” is detected in this way, “COEX” is highlighted and displayed. And when the user selects “COEX”, the controller 110 refers to the link information corresponding to the location keyword tag “COEX”, and provides a list of related service applications, that is, the service application “Foursquare” and the service “Facebook”. Provides a list of applications.

When the "Foursquare" application is selected among these service applications, the control unit 110 drives the "Foursquare" application as shown in FIG. 8 and provides a detailed screen related to "COEX" on the "Foursquare" application with reference to the link information. Let it be.

If the “Facebook” application is selected among the service applications of FIG. 7, the control unit 110 drives the “Facebook” application and refers to the link information, as shown in FIG. Allow detailed screens to be provided.

FIG. 10 is a diagram illustrating a case where a gallery application, which is a media application, is executed among native applications according to the embodiment shown in FIG. 6. When the execution of the gallery application is requested, the controller 110 detects a media keyword in the search database, drives a predetermined specific media service application, and searches for related media content using the media keyword. Then, the search result is displayed as a recommendation list. At this time, as shown in FIG. 10, a screen of a gallery application and a recommendation list that is a search result are displayed on the screen together.

In the above-described embodiment of the present invention, a case where a keyword tag is detected based on text directly input by a user has been described as an example. However, according to another embodiment of the present invention, a keyword matching the keyword tag may be detected in texts included in a message received from another user's digital device. A message received from another digital device may be, for example, a text message, a multimedia message, or an instant message. If text matching the keyword tag is detected in the received message, the process of determining the text as a keyword and providing a search result corresponding to the determined keyword will be similar to the above.

Further, according to another embodiment of the present invention, link information may be included in a text-based message and transmitted to another user's digital device. In other words, when the user A and the user B have a conversation through the instant message service application, an instant message is transmitted and received between the user A's digital device A and the user B's digital device. When a keyword is included in the instant message created by the digital device A, the digital device A may provide the user with a search result corresponding to the keyword according to the above-described process. In addition, when an instant message including a keyword is transmitted to the digital device B, the instant message may include a keyword tag and link information corresponding to the keyword tag. Accordingly, when the digital device B receives the instant message, the keyword is highlighted and displayed. When there is an input for selecting a keyword from the user, the digital device B may provide a list of related applications to the user by using link information included in the message. Thereafter, the search result according to whether the user selects the application may be provided in a similar process as described above.
