The first extraction unit 102 extracts one or more words based on the result of morphological analysis. That is, the first extraction unit 102 extracts words from the text information included in the content DA1. More specifically, the first extraction unit 102 extracts a word whose part of speech is a noun, for example.

  The first extraction unit 102 sends the extracted word to the second extraction unit 103. In addition, the first extraction unit 102 sends the extracted word to the first specification unit 107. The first extraction unit 102 generates word information (see FIG. 7) for displaying a list showing the extracted word list based on the extracted words, and the generated word information is stored in the first memory. Store in the device 13. Details of the data included in the word information will be described later (FIG. 7).

  When receiving the extracted word from the first extraction unit 102, the second extraction unit 103 reads the service meta information DA2 (see FIG. 6) from the first storage device 13. The second extraction unit 103 extracts, from the service meta information, a service name (specific information) associated with keyword information that includes the extracted word as the keyword. The second extraction unit 103 sends the extracted service name to the acquisition unit 104.

  The acquisition unit 104 acquires external information specified by the extracted service name from the external device 5. The acquisition unit 104 stores the acquired external information in the first storage device 13. The stored external information is read by the display control unit 105.

  Note that the service meta information DA2 includes information (that is, a service name) for acquiring the corresponding service via the network, and the acquisition unit 104 performs information service via the network based on the information. The external information (hereinafter also referred to as “main body data”), which is data for realizing, is acquired. The main body data does not need to be acquired via the network, and all or a part of the main body data is input from the input device 11, the optical disk drive 201, the magnetic disk drive 202, etc., and stored in the first storage device 13. It is good also as a structure. In this case, the acquisition unit 104 reads the main body data from the first storage device 13.

  The display control unit 105 causes the display device 15 to display the content DA1 in a plurality of parts. In addition, when the display control unit 105 causes the display device 15 to display the same word as the first word among the extracted words in association with displaying a part of the content DA1 on the display device 15, An image based on external information specified by the service name associated with the keyword information including the first word as a keyword is displayed on the display device 15.

  Further, the display control unit 105 changes the part of the content DA1 to be displayed on the display device 15 based on an instruction received via the input device 11 to change the part of the content DA1 to be displayed on the display device 15, for example. When the display control unit 105 causes the display device 15 to display the same word as the second word among the extracted words in accordance with the change of the part of the content DA1 to be displayed, the display control unit 105 displays external information to be displayed on the display device 15. The based image is changed to an image based on the external information specified by the service name associated with the keyword information including the second word as a keyword.

  The “part of the content DA1 to be displayed” refers to a part to be displayed in the content DA1 to be displayed (that is, a part of the content DA1 to be displayed). The same applies to “a part of the displayed content DA1” described later.

Further, the display control unit 105 will be described in more detail as follows.
The display control unit 105 determines the position of the part of the entire content DA1 based on the display of the part of the content DA1 on the display device 15. Specifically, it is as follows. When the image when the content DA1 is displayed does not fit on the display screen of the display device 15, the information processing device 10 displays a part of the content DA1. In this case, the display control unit 105 determines which part of the entire content DA1 is being displayed. For example, the display control unit 105 determines that 2/4 to 3/4 of the entire content DA1 is displayed (that is, 50% to 75% from the top). Note that the information processing apparatus 10 can sequentially display the remaining portions of the content DA1 by performing scroll display, page turning, and the like.

  The first specifying unit 107 specifies the position of the word extracted by the first extracting unit 102 in the content DA1. The first identification unit 107 sends the identified result to the estimation unit 108.

  Based on the determination result of the position by the display control unit 105 and the determination result of the position by the first specifying unit 107, the estimation unit 108 determines whether the extracted word (more precisely, the same word as the extracted word) Estimate the displayed word. For example, in the example of FIG. 2, the information processing apparatus 10 estimates, for example, words W10 to W14 as displayed words.

  More specifically, the estimation unit 108 performs the above estimation using information on the appearance position in word information (FIG. 7) described later. For example, the estimation unit 108 uses the information on the appearance position and the information on the number of characters of text that can be displayed in the area where the content DA1 of the display device 15 is displayed (for example, the display area 151 in FIG. 2). To do. Note that the estimation unit 108 sends the estimation result to the display control unit 105.

  Based on the estimated word, the display control unit 105 transmits external information specified by the service name (specific information) associated with the keyword information including the estimated word as the keyword from the first storage device 13. Reading and displaying an image based on the read external information on the display device 15. The following is a specific description based on FIG.

  Assume that the estimation unit 108 estimates, for example, words W10 to W14 (see FIG. 2) as displayed words. In this case, referring to the service meta information DA2 (see FIG. 6), the service names associated with the keyword information including at least one of the words W10 to W14 as keywords are service_0, service_1, service_2, and service. _3. Therefore, the information processing apparatus 10 reads the external information specified by the service_0, service_1, service_2, and service_3 from the first storage device 13, and displays the read external information.

  However, in this case, when the information processing apparatus 10 does not secure a display area that can display all the four external information, for example, the information processing apparatus 10 sequentially displays the external information two by two. Other display methods will be described later.

  Further, the display control unit 105 performs scroll display, next page display, or previous page display of the content DA1 based on the reception of a predetermined command via the input device 11. For example, when the user selects (clicks) the image 154 showing the operation buttons shown in FIGS. 2 and 3 with a mouse or the like, the information processing apparatus 10 displays information one page before the currently displayed page. . In addition, when the user selects an image 155 indicating an operation button, the information processing apparatus 10 displays information on a page (next page) after the currently displayed page. The estimation unit 108 performs the above-described estimation every time the command is received.

  With such a configuration, the information processing apparatus 10 can display external information corresponding to the displayed information on the display device 15 each time the location displayed on the display device 15 in the content DA1 is changed.

(Processing using priority)
Next, a configuration for setting the priority to the extracted word and a configuration for setting the priority to the service name (specific information) in the service meta information will be described. First, a configuration for setting a priority for the extracted word will be described.

  The first setting unit 111 sets the priority of the word extracted by the first extraction unit 102 (hereinafter also referred to as “word priority”) according to a predetermined rule. The first setting unit 111 stores the set word priority in the first storage device 13 in association with the word extracted by the first extraction unit 102 (see FIG. 7).

  In the case where there are a plurality of extracted words and the word priority is set, the second extraction unit 103 uses the service name (specific information) associated with the word having a high word priority in the service meta information. To extract.

  By adopting such a configuration, the information processing apparatus 10 can acquire external information specified by a service name associated with a word having a high word priority from the external apparatus 5.

  Therefore, the information processing apparatus 10 can reduce the amount of information acquired from the external apparatus 5 as compared with a configuration that does not use word priority. In addition, the information processing apparatus 10 can preferentially acquire information considered important for the user from the external apparatus 5.

  The word priority can be set based on information corresponding to the number of extractions for each word, for example. The word priority can be set as information according to the number of extractions, for example, based on the number of appearances of the word in the content and the novelty level of the word in the content. The number of appearances of words and the novelty level of words will be described later (FIG. 7).

  Next, a configuration for setting the priority to the service name in the service meta information will be described.

  Based on the word priority of the extracted word, the second setting unit 112 prioritizes the service name (specific information) associated with the keyword information including the word (hereinafter also referred to as “service priority”). ) Is set. For example, the information processing apparatus 10 sets a high service priority for a service name associated with a word having a high word priority.

  The acquisition unit 104 acquires, from the external device 5, external information specified by the service name having a high service priority among the service names extracted by the second extraction unit 103. That is, when using the priority, the acquiring unit 104 does not need to acquire external information specified by all service names extracted by the second extracting unit 103. For this reason, the amount of information acquired by the information processing apparatus 10 from the external apparatus 5 can be reduced.

  The display control unit 105 displays the acquired external information based on the service priority. For example, when the service priority of the service_3 is higher than the service priority of other services, the display control unit 105 causes the display device 15 to preferentially display the service_3, for example.

  The configuration of the second setting unit 112 may be as follows. That is, the second setting unit 112 may set the service priority for each service name according to the number of keywords included in each keyword information in the service meta information DA2.

  It is also effective to set the service priority in consideration of the word appearance position. When a plurality of words are included, for example, the second setting unit 112 sets the service priority to be higher as the appearance positions of these words are closer. An information service that includes words that appear in a concentrated position is an information service that matches the content of the content, rather than an information service that includes words that appear in dispersed positions in the content. .

  With such a configuration, the information processing apparatus 10 can provide an information service related to words that are impressive to the user in accordance with the content. For this reason, the information processing apparatus 10 can provide an effective service to the user. The information processing apparatus 10 may assign the service priority of the set service when associating a service name with word information (FIG. 7) described later.

  FIG. 7 is a diagram showing the word information DA3. Referring to FIG. 7, word information DA3 includes information indicating the appearance position of a word, a word, the number of appearances, a TF / IDF value, a novelty level, a priority level, and a service name.

  For example, when the content DA1 is displayed in a display area in which the number of characters that can be displayed in advance is set, such as the display area 151 set in advance as shown in FIG. Or information for specifying the position. The appearance position information is, for example, information indicating the page information, the offset value in the data of the content DA1, the number of the first character of the word counted from the first character of the text information, and the like. The first extraction unit 102 associates the appearance position with the word every time the word is extracted.

  The number of appearances is data indicating how many times the same word appears in the content DA1. When a certain word appears, the first extraction unit 102 performs a process of incrementing the value of the number of appearances by one for each word. The more frequently a word appears, the higher the possibility that the word is an important word in the content DA1.

  The degree of novelty is a scale indicating the novelty of a word. The first extraction unit 102 sets the novelty level of the word to the maximum when a word in the content DA1 first appears. The first extraction unit 102 decreases the novelty value according to the number of times the same word appears. When a word appears multiple times in the content DA1, it may be more likely that the first appearance will remain in the user's impression than when it appears for the second time or later. Therefore, it can be said that the greater the novelty, the more important the word in the content DA1.

  Next, the TF-IDF value will be described. The TF-IDF method is an algorithm for extracting characteristic words of a sentence. The TF-IDF value is represented by a product of TF (Term Frequency: word appearance frequency) and IDF (Inverse Document Frequency). The TF-IDF value is considered to be more important as the value is larger.

  By using text information in a plurality of contents other than the contents, it is possible to calculate a TF-IDF value of a word in the contents. When the content is composed of a set of sub contents such that the content is composed of a plurality of chapters, a TF-IDF value of a word in each chapter can be calculated. Therefore, the unit for calculating the TF-IDF value varies depending on how the text information of the content is structured. When the page structure is given to the text information, it can be calculated in page units, and when the chapter structure is given, it can be calculated in chapter units.

  Next, a specific method for setting the word priority will be described. The first setting unit 111 sets the word priority of each word included in the word information based on the number of appearances included in the word information, the TF-IDF value, or the novelty level. For example, the first setting unit 111 sets the word priority higher as the number of appearances increases. Alternatively, the first setting unit 111 sets the word priority higher as the TF-IDF value is larger. Alternatively, the first setting unit 111 sets the word priority higher as the novelty is higher.

  Other data stored in the word information DA3 includes the following data. For example, text data is provided with structured data such as heading information and title information, or display data for changing the display method from other text information such as highlighting, color display, and size specification. Sometimes. In such a case, the first setting unit 111 sets, as word information DA3, information indicating that the word is a characteristic word as a characteristic word than the word included in the text to which these data are not assigned. You may remember.

  Incidentally, the content DA1 stored in the first storage device 13 may include structure information defining a data structure of the content and / or a content display method, as shown in FIG. In this case, the configuration in which the word priority is determined using the TF-IDF value is a configuration in which the word priority is set based on the structure information.

  Further, when the content DA1 is configured as a plurality of partial contents, the information processing apparatus 10 may be configured such that the generation unit 110 and the first setting unit 111 perform the processing described below. That is, the generation unit 110 generates information indicating the importance of each extracted content for the extracted word based on the number of extractions for each word in the content DA1 and the number of extractions for each word in each partial content. To do. In that case, the first setting unit 111 sets the word priority of each word of the partial content based on the generated information indicating the importance. Information service suitable for the user can also be provided by such setting of word priority.

(Example of processing when non-text information is included)
Next, processing when content DA1 includes non-text information as shown in FIG. 3 will be described. In order to explain the processing, first, the data structure of the content DA1 will be explained.

  FIG. 8 is a diagram showing text information data having structure information of the content DA1. FIG. 8 shows data when the content DA1 is an electronic dictionary. Referring to FIG. 8, content DA1 is composed of header information surrounded by “<header>” tags and body data surrounded by “<body>” tags. In the header information, bibliographic information such as title information and author information may be described. The header information may store paragraph information as indicated by a “<paragraph>” tag.

  The value of the offset attribute stores the offset position of the data where the paragraph switches in the body data starting from the “<body>” tag. The “<data>” tag describes non-text information data such as an image included in the content. In the “<data>” tag, for example, a file name of non-text information, bibliographic information of non-text information, information for explaining contents of non-text information, and the like can be described.

  In the offset attribute, it is set at which position in the body data the non-text information should be displayed. Body data is described in the “<body>” tag. The character string enclosed by the “<big>” tag in the “<body>” tag is displayed larger than the other character strings. The “<body>” tag may include a tag indicating the display method in this way. The “<data>” tag may be included in the “<body>” tag. It contains the path information to the non-text information such as images and the data to be displayed in the text information. It is preferable to hold.

  Here, when the content includes non-text information, a method of giving meta information representing the content of the non-text information to the content using a word extracted from the text information will be described. “Give meta-information representing the contents of non-text information” means that information is described in the “<info>” tag in the “<data>” tag, as described in the data example shown in FIG. . When the non-text information is an image, the information processing apparatus 10 is displayed in parallel with the text information as shown in FIG.

  In the “<data>” tag describing the image data information, data indicating at which position in the text is displayed as shown in the offset attribute is stored. For this reason, the display control unit 105 grasps which position is currently displayed in the text, and causes the display device 15 to display the image data according to the offset value of the “<data>” tag. The display screen of the display device 15 includes images 154 and 155 (see FIGS. 2 and 3) showing operation buttons for the user to perform page operations. The user operates these operation buttons to display the current display. The position of the inside text (offset position) will change.

  Meta information is added to the image data by adding the text data in the vicinity of the position where the image data is displayed. The second specifying unit 114 specifies words around the non-text information among the words extracted by the first extracting unit 102. More specifically, the second specifying unit 114 specifies a word that appears at a position close to the display position of the image data based on information indicating the display position of the image data and information on the appearance position of the extracted word information. . The association unit 115 associates the identified word with the non-text information. In other words, the associating unit 115 adds the identified word to the meta information of the image data.

  For example, it is assumed that a value of 38 is stored in the offset value as information indicating the position where image data is displayed. When the word information of FIG. 7 is used to extract a word that appears at a position close to the display position of the image data, the information processing apparatus 10 extracts “rose” at the appearance position 35 and “flower” at 40. To do. In this case, the appearance position shown in FIG. 7 is expressed in the same unit as the offset value indicating the display position of the image data, and further, a word related to the image data is set by setting a threshold value close to the position in advance. Can be extracted. The extracted word is given as the meta information.

  The information processing apparatus 10 describes the extracted word in the “<info>” tag of the “<data>” tag. As a result, the meta information given to the non-text information in the content DA1 is updated. Images in e-books are considered to be used to visually express the contents of text information in the text more clearly, so whether the text information around the image is related to the contents of the image. Or it is a sentence explaining the contents in many cases. Therefore, it can be said that adding a word appearing at a position close to the display position of the image as meta information of the image gives a word related to the image.

  By enriching the meta information representing the contents of the non-text information, the service presented in parallel when displaying the non-text information can be changed to a service related to the non-text information. In the case of content with a lot of character information such as an electronic book, it can be said that non-text information such as an image tends to remain in the impression for the user. Therefore, if a service related to non-text information is presented with priority on a page on which non-text information is displayed, an information service can be provided more effectively.

  When non-text information is included, the word priority may be set by configuring the first setting unit 111 as described below. As described above, when there are a plurality of extracted words, the second extraction unit 103 extracts a service name associated with a word having a high word priority in the service meta information DA2. The 1st setting part 111 performs the process which makes the word priority of the word matched by the matching part 115 higher than the word priority already set. When the first setting unit 111 performs such processing, the information processing apparatus 10 can provide an information service more suitable for the user.

<Screen display>
Returning to FIG. 2 again, the display screen displayed on the display device 15 by the information processing apparatus 10 will be described in more detail. The display device 15 receives data to be displayed from the display control unit 105 and performs display based on the data. FIG. 2 is a display screen for browsing content, and the content DA1 is displayed on the left side (display area 151) of the display screen.

  In the example of FIG. 2, the information processing apparatus 10 displays content of an electronic book. When the content of the electronic book is composed of structural information as shown in FIG. 8, for example, the display control unit 105 converts the data into display data as shown in FIG. The display control unit 105 analyzes the structure information and converts it into image data.

  In the example of FIG. 2, a service screen is displayed in parallel with the content DA1. These services are services associated with words appearing in a part of the displayed content DA1. On the display screen, an image of an operation button for changing the display position of the content DA1 is arranged. For example, an operation button image 154 for returning the page to the front and an operation button image 155 for sending back are arranged. When the user operates these buttons, the user can turn the displayed page. can do.

  By such an operation, the information processing apparatus 10 changes the word in the displayed content when the display position in the content DA1 is changed. Furthermore, the information processing apparatus 10 also changes the service provided to the user. That is, the information processing apparatus 10 displays an image of a service associated with a newly displayed word on the display device 15 when the page is turned.

  Operation information such as a page operation is input to the input receiving unit 101 of the control unit 12 via the input device 11. When receiving the operation information, the input receiving unit 101 sends the operation information to the display control unit 105. The display control unit 105 provides the content based on the information stored in the first storage device 13 so as to change the display position of the content from the operation information and also change the service provided in parallel from the new display position. The information service to be determined is determined, and data used for screen display is generated. Note that the display control unit 105 causes the display device 15 to display information such that the contents of the service can be understood in parallel with the content. In this way, the information processing apparatus 10 can provide a service that is more effective for the user by providing a service associated with the page that the user is currently paying attention to.

  In the above, the service provided by the information processing apparatus 10 is updated by a page operation by the user. Below, the structure which changes the service which the information processing apparatus 10 provides by other user operation is demonstrated.

  In this case, the configuration of the second extraction unit 103 may be as follows. That is, the second extraction unit 103 receives the instruction for designating one area in a part of the content DA1 displayed on the display device 15 via the input device 11, and the designated one area or designation The service name (specific information) associated with the keyword information including the extracted word as a keyword displayed in a predetermined range centered on the one area is extracted from the service meta information. Specifically, it is as follows.

  When the information processing apparatus 10 receives a predetermined operation for a part of the displayed content DA1 through the input device 11 while the user is viewing the content DA1, the information processing apparatus 10 The position in the content DA1 is acquired from the operation position. Furthermore, the information processing apparatus 10 provides an information service associated with a word that appears close to the acquired position.

  “Predetermined operation” refers to information such as selecting a word in the content DA1 or marking a word, performing an operation that focuses on the word, performing an enlargement operation at a certain position, bookmarks, etc. This includes operations such as assigning In addition, “predetermined operation” means selecting and selecting a word by designating a start point and an end point in the content DA1 by operating a mouse while viewing the content on the information processing apparatus 10. For example, an operation such as using a search service or a dictionary lookup service for the selected word is applicable.

  In this way, when the information processing apparatus 10 receives an operation from a user for a certain word, the word focused on by the user is configured to provide an information service associated with the word. Can provide information services in line with

  When the information processing apparatus 10 accepts an operation for a certain position on the content DA1 such as an enlargement operation or a bookmark assignment, the information processing apparatus 10 acquires the position in the content DA1 from the specified operation position, and is close to the acquired position. An information service associated with the words appearing in the URL may be provided.

  Such an operation by the user is input from the input device 11 as operation information. The display control unit 105 acquires the position of the content from the operation information, and determines the information service to be provided from the word information stored in the information service associated with the word. Then, the display control unit 105 updates the information service provided to the user by causing the display device 15 to display the determined information service.

<Word editing>
Next, a method of editing a word using the word information DA3 created by the first extraction unit 102 as shown in FIG. 7 will be described. First, the display control unit 105 receives a predetermined command via the input device 11 and then associates the extracted word with the priority of the word (hereinafter, “word list”). Table ”is also displayed on the display device 15. The editing unit 113 edits the priority in the word information DA3 based on the external input via the input device 11 in a state where the word list is displayed on the display device 15. The editing unit 113 changes priority, deletes priority, adds priority, and the like as the editing.

  Specifically, the display control unit 105 reads the word information DA3 from the first storage device 13, generates a word list based on the read word information, and causes the display device 15 to display the generated word list. . More specifically, the display control unit 105 creates display data for word editing from the word information DA3 to which the word priority is assigned so that the user can edit the word information, and the created display data is displayed. It passes to the output unit 106. The output unit 106 passes display information data for word editing to the display device 15. The display device 15 displays the display data. The “user” here is not a user who views the content DA1, but a user who edits additional information other than the main body of the content DA1.

  Specifically, the display control unit 105 creates a word list so that word information is arranged and displayed in order of word priority. The user sees the list arranged in order of word priority, and performs editing operations such as changing the word priority and deleting unnecessary words. When the user inputs for editing, the input receiving unit 101 receives the input as editing information. The first extraction unit 102 updates the word information stored in the first storage device 13 based on the editing information. The information processing apparatus 10 extracts an information service using the updated word information, and displays the extracted information service on the display device 15 together with the content DA1.

  FIG. 9 is a diagram showing an example of a word list editing screen (hereinafter referred to as “word editing screen”). Referring to FIG. 9, display control unit 105 displays content DA1 in left display area 161 on word editing screen 15A, and displays words arranged in order of priority in right display area 162 on word editing screen 15A. . The display control unit 105 displays images 163 to 167 showing operation buttons for editing in the lower area on the word editing screen 15A.

  The information processing apparatus 10 receives an input for selecting a word to be edited from the displayed words through the input device 11. Further, the information processing apparatus 10 detects that one image has been selected from the images 163 to 165 showing operation buttons such as “delete”, “high priority”, and “low priority”.

  The “delete” operation button 163 is used to delete the selected word from the list. When the information processing apparatus 10 detects that “delete” is selected by a user operation, the word is not displayed on the word editing screen 15A.

  The “high priority” operation button 164 is used to make the priority of the selected word higher than the priority of the word displayed one level above. When the information processing apparatus 10 detects that “high priority” is selected by a user operation, the information processing apparatus 10 displays the selected word so that the position of the word displayed on the word editing screen 15A is switched. Let Referring to the example of FIG. 9, when the information processing apparatus 10 detects that the word W20 is selected by the user's operation and then detects that the high priority is further selected, the information processing apparatus 10 The position of is replaced and displayed. The “low priority” operation button 165 is used to set the word priority of the selected word lower than the word priority of the word displayed one level below.

  The “next” operation button 166 and the “previous” operation button 167 are used to accept an operation for changing the portion of the content DA1 displayed in the display area 161 on the word editing screen 15A. For example, when the information processing apparatus 10 detects that “next” has been selected by a user operation, the information processing apparatus 10 displays the next page of the currently displayed page in the display area 161. Further, when the information processing apparatus 10 detects that “Previous” has been selected by a user operation, the information processing apparatus 10 displays the previous page in the display area 161.

  The word information DA3 includes information on the appearance position of the word. Therefore, the information processing apparatus 10 displays words to be displayed in the right display area 162 in the display screen based on the position of the content being displayed in the left display area 161 in the display screen in the entire content DA1. To do.

  Here, a case where a part of the content of the content DA1 is displayed will be described as an example. The word list displayed on the display screen is a word included in the partial contents displayed in parallel. For example, when the offset value of the position of the content DA1 being displayed is 0 to 30, the information processing apparatus 10 displays the words whose word appearance positions are 0 to 30 in order of priority. When the display position of the content is changed by pressing the “next” operation button 166 or the “previous” operation button 167, the information processing apparatus 10 updates the word list according to the position.

  The user can increase the word priority of a word that is intentionally impressed by editing a word that appears in the partial content being displayed. The information service to be provided is determined based on words, and at that time, a word having a higher word priority is given priority. When it is desired to prioritize services in a field related to a certain word B over services in a field related to a certain word A, by editing the word B so that the priority of the word B is higher than the word A, the user can The display can be adjusted.

  Further, by editing the content of the partial content being displayed so that the priority of the impressive word is higher, it is possible to extract an information service corresponding to the impressive word for the viewing user. For this reason, it is possible to provide an effective information service to the user.

  Thus, the ability to extract words contained in the displayed content DA1 and edit the priority thereof is effective in providing the user with an information service related to the displayed content DA1.

<Edit service>
Next, a method for editing the service priority will be described. First, the display control unit 105 receives a predetermined command via the input device 11 and then associates a service name (specific information) with the service priority (hereinafter, “service list”). Table ") is displayed on the display device 15. The editing unit 113 edits the service priority based on the external input via the input device 11 in a state where the service list is displayed. The editing unit 113 changes priority, deletes priority, and the like as editing of the service priority.

  Specifically, the display control unit 105 creates a service list in order to edit service priorities. The output unit 106 outputs the created service list to the display device 15. The display device 15 displays a service list. Editing information for the user to edit the service list such as changing the priority is received by the input receiving unit 101. When the input reception unit 101 receives the editing information, the first extraction unit 102 changes the service meta information stored in the first storage device 13.

  FIG. 10 is a diagram showing an example of an editing screen (hereinafter referred to as “service editing screen”) for editing the service list. Referring to FIG. 10, content DA1 is displayed in display area 171 on service editing screen 15B. In the service editing screen 15B, service_0 and service_1 are displayed in the display area 172 as information services displayed in parallel with the content DA1. These contents DA1, service_0, and service_1 are displayed on the display device 15 when the user views the contents.

  On the service editing screen 15B, the information processing apparatus 10 displays the service list 174 in order of service priority. In the example of FIG. 10, the service_2 in the list is selected, and the selected service_2 is displayed in the display area 175.

  The information processing apparatus 10 displays these information services because the service priority of the service_0 and the service_1 is high. For example, when it is desired to present another information service, the provided service can be changed by changing the arrangement of the list. Hereinafter, the processing will be specifically described.

  When the information processing apparatus 10 detects that the “high priority” operation button is selected in a state where the service_2 is selected, the information processing apparatus 10 increases the priority of the selected information service. For example, when the information processing apparatus 10 detects that the “high priority” operation button has been selected (operated) once, the information processing apparatus 10 increases the priority order by one. When the information processing apparatus 10 detects that the “high priority” operation button is continuously selected, the information processing apparatus 10 increases the priority to the order in which the information service is displayed on the display device 15. By this processing, the information processing apparatus 10 updates the currently provided information service with the selected information service. For example, when the priority of the service_2 is higher than the service_1, the information processing apparatus 10 changes the image of the service_1 currently being displayed to the image of the service_2.

  In this way, the information processing apparatus 10 can change the information service provided to the user. As described above, the information processing apparatus 10 identifies a word included in the content being displayed, and provides a service in priority from the information service associated with the word having the highest priority. However, when the user wants to change the provided information service, the user only needs to edit the service editing screen 15B as described above.

<Control structure>

<Modification>
(Set word priority based on preference information)
When the information processing apparatus 10 can acquire the preference information indicating the user's preference from the outside, the first setting unit 111 sets the word priority of the word extracted by the first extraction unit 102 based on the preference information. It may be set. In this case, the second extraction unit 103 extracts a service name associated with a high priority word in the service meta information DA2.

  When the preference information is expressed by text information such as a word of interest or a genre name such as “flower” or “history”, the information processing apparatus 10 prioritizes a word that matches the preference information. Set the degree high. User preference information is input from the input device 11 and stored in the first storage device 13. The preference information may be accumulated from a history of contents viewed by the user. When the user views the content, the information processing apparatus 10 may accumulate words extracted by content analysis as user preference information and use them for setting priority.

(Content search)
The word extracted from the content may be used for content search. Hereinafter, a configuration of an information processing apparatus that searches for content using words extracted from the content in this way will be described.

Referring to FIG. 14, information processing apparatus 10 </ b> A includes input device 11, control unit 12 </ b> A, first storage device 13, second storage device 14, and display device 15. The control unit 12A includes a search unit 109 in addition to the blocks included in the control unit 12 (see FIG. 5). In FIG. 13, each block included in the control unit 12 is not shown for convenience of explanation.

  As described above, the first storage device 13 stores a plurality of contents. The search unit 109 searches a plurality of contents for content in which the character input via the input device 11 matches the extracted word.

  The display control unit 105 is based on external information specified by a service name (specific information) associated with the searched content and keyword information including the matched word as a keyword based on the search of the content. The image is displayed on the display device 15.

  Further, the content preferably includes an area for storing data used for content search as described above. Moreover, it is preferable that 10 A of information processing apparatuses store the said word in the said area | region based on the word extracted.

  A more specific description of such content search is as follows. When searching for content by inputting characters, it is necessary to extract content that includes the characters that match the input characters. In order to improve the accuracy of the search, content whose input characters are more suitable for the content should be extracted. For example, when the input character is “history”, content whose content is “history” is more preferable than simply extracting content including the word “history”.

  Therefore, the information processing apparatus 10A extracts a word having a high word priority from the content based on the set priority, and stores it as a search word for determining a word that matches the input character at the time of search. Keep it. As a result, a word having a high word priority is highly likely to be a word representing the feature of the content, so that it is possible to search for a highly accurate content that matches the meaning of the input character.
