Accordingly, the display control unit 123 can display the related information searched for and the partial information on which the search is based on the display unit 124 in association with each other.

  The video information storage unit 140 stores video information that records the broadcast video. Video information includes still images, moving images, audio, music, and text-described metadata.

  Next, an information search / display process performed by the information search / display apparatus 100 according to the first embodiment configured as described above will be described. FIG. 5 is a flowchart showing an overall flow of processing for searching for and displaying related information in the information search / display apparatus 100 according to the first embodiment.

  First, when the user inputs a search request for related information from the input unit 121, the search request acquisition unit 122 receives the search request for related information from the input unit 121 (step S501). Next, related information search processing is executed by the related information search unit 110 (step S502), and related information display processing is executed by the display control unit 123 (step S503). Details of the related information search process and the related information display process will be described later.

  FIG. 6 is a flowchart showing the flow of related information search processing in step S502 shown in FIG. Details of the related information search process will be described below.

  First, the metadata acquisition unit 111 acquires metadata attached to the video information as text data from the video information requested to be searched (step S601). Next, the voice recognition unit 112 recognizes the voice included in the video information, and acquires the recognition result as text data (step S602). The speech recognition method may be configured by any of general speech recognition, such as a method of performing phoneme recognition, word recognition, and sentence recognition while performing frequency analysis of speech and referring to a word dictionary or the like.

  Next, the image recognition unit 113 recognizes a partial image such as a person, a building, or a telop included in the video information, and acquires the recognition result as text data together with the recognized partial image range (step S603). Here, the image recognition includes both pattern recognition for recognizing what an object is in the image and character recognition for recognizing a character present in the image. As an image recognition method, any of general image recognition methods such as a shortest distance method, a cross-correlation method, and a Fourier phase correlation method may be used.

  Next, the search keyword generation unit 114 divides the text data acquired by the metadata acquisition unit 111, the voice recognition unit 112, and the image recognition unit 113 into words, and generates a search keyword used for the search (step S604). . For example, it is possible to apply a general morphological analysis technique, divide text data into morphemes, extract independent words, and use as search keywords. Further, the text data acquired by the metadata acquisition unit 111, the voice recognition unit 112, and the image recognition unit 113 may be configured as a search keyword as it is. This is only an example, and any method can be applied as long as it is a method for extracting a meaningful search keyword from text data in order to search for related information.

  Next, the search keyword generated by the search keyword generation unit 114 is specified, and the search unit 115 executes a search process for the search system connected to the Internet (step S605). The search target is not limited to the search system connected to the Internet, and any information storage means can be used as long as it can acquire related information for a certain keyword. For example, a search system connected by a communication line other than the Internet, or an in-house or external database connected to a network and storing various information may be searched.

  Next, the semantic analysis unit 116 receives the search results searched by the search unit 115 and performs semantic analysis, thereby assigning semantic attributes to the words included in the respective search results (step S606).

  For example, when the word “OO restaurant” is obtained, it cannot be distinguished only by the word whether it is used as a place to eat or drink in a gourmet program or as a landmark for directions. . Therefore, by performing semantic analysis and assigning detailed attributes to words, it is possible to eliminate ambiguity and to acquire related information that more matches user preferences. The semantic analysis may be configured by any of the general semantic analysis methods in natural language processing.

  Next, from the search result of the related information to which the semantic analysis unit 116 has added the semantic attribute, the search result selection unit 117 includes information unique to the user such as the user's viewing history, user's preference, and related information searched in the past. The search result is selected with reference to the user preference information (step S607).

  Here, selection of the search result includes excluding a search result that does not match the user's preference from the search result, and adding information that matches the user's preference. For example, even when information related to restaurants other than Japanese food is included in the search results, when “Japanese food” is present in the preference keywords for the user stored in the preference keyword storage unit 131, the search results for restaurants other than the Japanese food Is deleted. Further, for example, when the profile of the person does not exist in the search result of a certain person but the profile of the person is stored in the search history storage unit 132, the profile is added as the search result.

  Next, the related information search unit 110 stores the related information, which is the result selected by the search result selection unit 117, in the search history storage unit 132, and extracts words from the related information by morphological analysis or the like, and the preference keyword storage unit It stores in 131 (step S608). As a result, when a search request is received again later, it becomes possible to refer to these pieces of information and select a search result that meets the user's preference with higher accuracy.

  FIG. 7 is a flowchart showing the flow of related information display processing in step S503 shown in FIG. Details of the related information display process will be described below.

  First, the display control unit 123 reads related information that is a search result (step S701), and also reads video information that is a search target (step S702). Next, the display control unit 123 displays the partial information on the basis of the search from the partial information included in the read video information so that the partial information becomes clear (step S703).

  For example, a recognized partial image is displayed for an image such as a person, a building, or a telop, and a search keyword used for the search is displayed for metadata. At this time, the coordinate information of the partial image stored in the search history storage unit 132 can be used. For voice, text data that is a result of voice recognition of video information is displayed on the display unit 124, and then the text data is enclosed and displayed. In addition, although the preference keyword is not information included in the video information, when there is a preference keyword used for selecting the search result, the preference keyword is displayed on the display unit 124. Note that the display method of the partial information is not limited to these, and any display method may be used as long as the partial information that is the basis of the search is displayed clearly.

  Next, the display control unit 123 displays the related information read in step S701 and the partial information displayed in step S703 in association with each other on the display unit 124 (step S704). Here, displaying in association means that information is presented so that the related information of the search result can be clearly understood based on which partial information in the video information is searched.

  For example, the related information and the partial information on which the search is based are associated with each other by connecting with a line, the associated information is displayed by surrounding it with a frame of the same color, and the same code is attached. The method of displaying in association with each other, the method of displaying in association with pop-up display, and the like. In addition, the presentation of information is not limited to being displayed on the screen, and may be a method of reading information by voice. Note that these are examples, and the related information of the search result is not limited to these as long as the information is presented so that the partial information in the video information can be clearly identified. Absent.

  Next, the search request acquisition unit 122 determines whether or not a search is further requested for the related information displayed on the display unit 124 (step S705). When the search is requested (step S705: YES), the related information search unit 110 executes the related information search process again (step S706). When the search is not requested (step S705: NO), the related information display process ends.

  FIG. 8 is an explanatory diagram showing an example of the related information display screen 800 displayed on the display unit 124 as a result of the related information search process and the related information display process in the information search and display apparatus 100 according to the first embodiment.
