An apparatus for providing a program search service of another channel during program broadcasting according to an embodiment of the present invention includes a search log DB 341, a search engine 342, a recommended search term extractor 343, and a program information extractor 344. , A program list providing unit 345, a search area providing unit 346, a search result providing unit 347, and a program switching unit 348.

For reference, the components illustrated in FIG. 4 according to an embodiment of the present invention mean software components or hardware components such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC), and perform predetermined roles. .

However, 'components' are not meant to be limited to software or hardware, and each component may be configured to be in an addressable storage medium or may be configured to reproduce one or more processors.

Thus, as an example, a component may include components such as software components, object-oriented software components, class components, and task components, processes, functions, properties, procedures, Subroutines, segments of program code, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays and variables.

Components and the functionality provided within those components may be combined into a smaller number of components or further separated into additional components.

First, the search log DB 341 overlaps search log data received from the search engine 342 and related search terms corresponding to a specific search word (for example, other search terms searched by a user searching for a specific program and a specific program name). Or search term).

For reference, the search log DB 341 combines not only the related search term corresponding to a specific search word, but also data directly input by a broadcasting company, a previously collected program information, caption / subtitle information transmitted simultaneously with the corresponding program, and the like. You can configure a pool.

On the other hand, based on the search log DB 341, the search term extractor 343 generates a keyword for each program and variations (similar words) of the suggestion keyword. Hereinafter, the search term extractor 343 will be described with reference to FIG. ) Will be described in detail.

FIG. 5 is a block diagram of a recommendation keyword extracting unit 343 for generating a recommendation keyword for each program and a variation (similar word) of the recommendation keyword according to an exemplary embodiment of the present invention.

Referring to FIG. 5, the recommended search term extractor 343 according to an embodiment of the present invention may include a viewer predictor extractor 343a, a recommended keyword determiner 343b, a program-keyword time synchronizer 343c, and a seed ( Seed) may include a keyword DB 343d, a viewer predictor DB 343e, and a recommendation keyword DB 343f for each program.

The recommended search word extractor 343 may perform an operation in cooperation with a normal search server 350 or the search engine 342. The recommended search word extractor 343 according to an embodiment of the present invention may utilize information of a search log DB 341 storing a log of a search query transmitted to the search server 350 or the search engine 342.

When a program is played back through the user terminal 330, keyword search for a broadcast program is intensively generated by the user terminal 330 statistically before and after the airing time, which is a search log DB 341. The query, search time and user identification number are stored in the.

Hereinafter, the operation of the recommended search word extractor 343 will be described in detail.

The viewer predictor extractor 343a of the recommended search term extractor 343 operates in conjunction with the search engine 342 and the seed keyword DB 343d. Meanwhile, the search engine 342 may be replaced with an external search server 350 that provides a web search.

In the seed keyword DB 343d, basic keywords related to a specific program, that is, seed keywords, are stored in match with the broadcast time zone. For example, the seed keyword may be the name of the program or a variant thereof.

Meanwhile, the seed keyword may be stored by dividing the keyword into categories and giving different weights. For example, in the drama category, the first category may include a title and a cast name, and the second category may include an actor name and a crew. Here, the first category having a higher search probability may have a higher weight than the second category.

The viewer predictor extractor 343a checks whether there is a seed keyword stored in the seed keyword DB 343d among search terms received by the search server 350 or the search engine 342 within a predetermined time period before and after the program broadcast time. The identification number of the user who has searched for the seed keyword is extracted.

For reference, the viewer corresponding to the extracted user identification number may be classified as a viewing predictor. For classification of the viewing predictor, only a user who searches for a seed keyword having a threshold number of times or more may be classified as the viewing predictor.

In addition, when the auto-completion function is provided in the search box, the search word by the auto-completion function is included, but keywords provided by the search server 350 or the search engine 342 (eg, popular search terms, recommended search terms, and real-time) are included. Users who have searched by selecting a rising search term) may be excluded from the viewer.

As described above, when the viewing predictor is extracted, the user identification number of the viewing predictor is stored in the viewing predictor DB 343e. In the viewing predictor DB 343e, the user identification numbers are stored in match with a specific broadcast program or a series or group of the specific broadcast program.

On the other hand, the recommended keyword determination unit 343b refers to the viewing predictor DB 343e and collects search terms searched by the viewing predictor in the broadcast time zone of the corresponding program. In addition, the recommended keyword determining unit 343b determines the keyword as a keyword when the collected keyword satisfies a predetermined condition, and includes the keyword in the keyword set. The predetermined condition may be a condition that the correlation between the search word of the viewer and the corresponding program is greater than or equal to a threshold.

The recommended keyword determination unit 343b determines a keyword that satisfies the above condition as a recommended keyword for the corresponding program, and generates a keyword set for the corresponding program.

Meanwhile, the program-keyword time synchronizing unit 343c performs a function of matching the keywords included in the keyword set for each reproduction time zone of the program. For example, based on the number of times of keyword search for each time zone at 60-second intervals, a keyword having a large ratio for each time zone is selected.

In this case, a predetermined inappropriate keyword may be filtered. For example, an inappropriate keyword as a keyword such as live broadcasting, re-broadcasting, viewing, organizing, and playing time may be removed. For reference, the search log DB 341 also stores search time information on the keyword selected as the recommended keyword, so that the keywords included in the keyword set can be matched and synchronized for each broadcasting time zone of the program.

Finally, the keywords matched for each program are stored in the program-specific recommendation keyword DB 343f. Therefore, when subsequent content of the same program is aired, recommended keywords of the corresponding program may be provided in real time. As described above, the configuration and operation of the recommendation search word extractor 343 is for illustrative purposes only, and it is possible to generate a recommendation keyword for each program by various other algorithms.

On the other hand, the program information extracting unit 344 grasps the broadcasting time of the program currently being broadcast based on the broadcasting schedule information, and extracts the program information of each channel that is broadcasted in the identified broadcasting time and the adjacent time zone.
