Industrial application fields

  The present invention relates to an information service system that provides a user with information selected from a plurality of pieces of information, such as an electronic mail system, a database system, a television receiver, and a radio receiver.

  There are various systems in which a user performs various operations to select and obtain desired information from among a plurality of information. For example, many information service systems such as a television receiver, a radio receiver, an e-mail system, and a database system are known.

  In such an information service system, as a technique for supporting the selection of user information, for example, Japanese Patent Laid-Open No. 3-284077, “Program Information Display and Control,” which supports selection of a TV program to be viewed in a television receiver. The technique described in “Apparatus” is known.

  This technology displays television program information on a television receiver, and on the displayed television program information, accepts instructions for channel selection, program reservation, and recording, thereby selecting a program in a newspaper. This alleviates the user's annoyance of having to refer to a magazine that contains a program column or program guide.

  In other words, this technology supports the user's selection of information by presenting a list of information contained in the information source and accepting the selection of information based on the presented information list in the information service system. It can be said that this is a technology that

  As in the technique described in Japanese Patent Laid-Open No. 3-284077, the number of pieces of information included in an information source can be reduced even by a technique that supports a user's selection of information by presenting a list of information included in the information source. If there are many items, the number of items included in the list increases, which causes a problem that the operation for finding the information item desired by the user becomes complicated.

  Also, for example, if you want to give all the information necessary for education of the user to the user in the education stage, entrusting the user with all information selection, There is a problem that bias occurs.

  An object of this invention is to provide the information service system which can provide the information which a user desires more simply and appropriately.

  It is another object of the present invention to provide an information service system that can notify a user of information that is lacking.

  A feature of the present invention that achieves the above object is that learning means for learning a class that the user is interested in from the access information of the user, and information that belongs to the class based on the class that the user is interested in learned Information selection means for extracting and providing the information from the information source.

  The feature of the present invention that achieves the other object includes means for storing a plurality of classifications to be used by the user, and the classification that the user is interested in among the plurality of classifications stored in the storage means. And a means for searching for and outputting other classifications except for.

  As described above, according to the present invention, information desired by the user can be easily estimated, and information desired by the user can be appropriately provided.

  Further, it is possible to notify the user of information that is lacking for the user.

Action

  According to the information service system of the present invention, a class in which the user is interested is learned from the user's access information, and information belonging to the class is obtained from the learned class in which the user is interested as an information source. Therefore, the information desired by the user can be easily estimated, and the information desired by the user can be provided appropriately.

  In addition, according to the information service system of the present invention, other classifications except for the classification in which the user is interested are retrieved and output from among a plurality of classifications to be used by the user stored in the storage means. Therefore, it is possible to notify the user of information that is lacking for the user. For this reason, the user can easily obtain information on a new classification that he / she was not aware of.

  A first embodiment of the information service system according to the present invention will be described below.

  FIG. 1 shows the configuration of an information service system according to the first embodiment.

  As shown in the figure, the information service system according to the first embodiment includes a user identification determination unit 1, an information selection input unit 2, a user-specific access information classification unit 3, an access history management unit 4, and an interest information determination unit 5. , Information source 6, editing means 7, monitor 8, interest information index presentation means 9, model access information storage means 10, comparison means 11, personal deficiency information determination means 12, activation means 22, interest level input means 60, and access A history reset means 70 is provided.

  The user identification determination unit 1 receives an input of information for identifying a user who accesses information, and determines a user. User identification methods include assigning operation keys to the user in advance, identifying the user by pressing this operation key, etc., and entering personally-dependent information such as registered names and passwords. It is possible to adopt a method of accepting, identifying a user, a method of identifying a user by photographing a fingerprint, comparing it with a pre-registered fingerprint pattern, and the like. An ID card or the like can also be used for inputting user identification information.

  The information selection / input means 2 accepts designation of a mode, which will be described later, and designation of information to be accessed. The user access information classification means 3 determines the classification to which the specified information belongs. The information selection input means 2 also accepts various operations such as print output, copy output, screen switching, and screen scrolling of information displayed on the monitor 8.

  The access history management means 4 manages access history information indicating how much interest each user has in each category of information. How to obtain this interest level will be described later. The interest information selection means 5 is taken out from the information source 6 according to the management contents of the access history management means 4 (for example, the degree of interest for the corresponding user) in the automatic mode, and is sent to the editing means 7 as selection information 15. Output. In the manual mode, the interest information selection means 5 takes out information corresponding to the classification determined by the user access information classification means 3 from the information source 6.

  The information source 6 is, for example, a database (memory) that stores a plurality of information classified into a plurality of categories, or a plurality of broadcasting stations. The editing means 7 edits the selection information 15 and displays the edited information content on the monitor 8.

  The degree-of-interest input means 60 inputs information about the degree of interest and weight information for calculating the degree of interest by a direct operation by the user.

  The interest information index presenting means 9 displays the information index on the monitor 8 via the editing means 7. The model access information storage unit 10 stores, for each user, a model of information classification to be used by the user. When activated by the activation unit 22, the comparison unit 11 displays the corresponding user model stored in the template access information storage unit 10 and the interest level of the corresponding user managed by the access history management unit 4. And compare. The individual deficiency information determination means 12 determines the information that the user lacks based on the comparison result of the comparison means, and displays the classification of the information obtained by the determination on the monitor 8 via the editing means 7. To do. The access history reset means 70 inputs the cancellation information of the individual access history information stored in the memory 4b of the access history management means 4 by the operation of the user, and this cancellation information is input to the access history information management means. 4 is output. Cancel information can be set for each user and category.

  Now, for example, as shown in FIG. 2, the information source 6 has a plurality of pieces of information belonging to a plurality of information classifications such as a redundancy configuration, a signal selection function, a transmission circuit configuration, a transmission code system, clothes, and Japanese clothes. Suppose you are. In FIG. 2, in order to show that the first embodiment can be applied to various fields, the information source 6 which is a database is divided into science and technology fields such as control technology and transmission technology, and clothing. It is shown as having information of information classification belonging to the commercial field such as mail order sales. By the way, when including information on different fields as described above, the information source 6 may be realized as a set of information sources for each field.

  The operation of the information service system according to the first embodiment will be described below.

  First, the operation when the interest information index presenting means 9 and the model access information storage means 10 are not used will be described.

  FIG. 3 shows an operation flow of the information service system in this case.

  As shown in the figure, when the information for identifying the user is input directly from the user or through a terminal (not shown), the information service system uses the user identification determination means 1 to identify the user. The user identification information that identifies and identifies the user obtained by the determination is output to the user access information classification means 3 (step 301). Next, the information selection input means 2 receives the request information for designating the mode and the information to be accessed from the user, and outputs the result to the access information classification means 3 for each user (step 302). In the first embodiment, the information service system is provided with two modes, “automatic mode” and “manual mode”. Only when the “manual mode” is designated, the user includes designation of information to be accessed in the request information. When “automatic mode” is designated, the information service system guesses information that the user has a high degree of interest and automatically selects it. Therefore, when the user designates “automatic mode”, the user only has to input information for identifying and information indicating the automatic mode.

  Next, the access information classification means 3 for each user determines whether the mode designated by the request information from the information selection input means 2 is the automatic mode or the manual mode (step 303).

  When the manual mode is designated, the access information classification means 3 for each user outputs information specifying the designated information to the interest information selection means 5 from the inputted request information. Further, the information classification to which the specified information belongs is determined, classification specification data for specifying the determined information classification is created, and output to the access history management means 4 together with the user identification information for specifying the user (step) 304). The determination of the information classification to which the specified information belongs by the user-specific access information classification means 3 is performed by, for example, assigning one or more keywords to each information classification in advance and assigning each information to the information classification to which the information belongs. -Assign a keyword that matches or partially matches a keyword, and accept the specification of information by the keyword, and select a keyword that matches or partially matches the entered keyword. It is possible to perform the information classification having the information classification to which the information belongs. Specifically, for example, it can be realized by an inference means having a condition part and a conclusion part such as an if-then type.

  The access history management means 4 takes in the information (user identification information and classification designation data) from the user-specific access information classification means 3 and temporarily stores these information in the memory 4b (step 305).

  On the other hand, the interest information selection means 5 takes out information belonging to the classification specified by the classification designation data output from the user-specific access information classification means 3 from the information source 6 (step 306). Thereafter, the interest information selection means 5 outputs the information extracted from the information source 6 to the editing means 7 as selection information 15 and outputs confirmation information 19 indicating that to the access history management means 4. Also, if there is no designated information in the information source 6, the interest information selection means 5 outputs information indicating that there is no corresponding information to the editing means 7 (step 307).

  The editing means 7 that receives the information from the interest information selecting means 5 edits the information so that the user can easily see it, and outputs it to the monitor 8 (step 308).

  On the other hand, the access history management unit 4 determines whether the confirmation information 19 from the interest information selection unit 5 continues for a certain period, or the user accesses the information displayed on the monitor 8 using the access display information 18. (Step 309). This determination is for determining whether the information selected from the information source 6 is what the user desires to obtain. In any of the above cases, the user has obtained the desired information. It is determined that the user has accessed the desired information. Here, the access display information 18 is input to the information selection input means 2 when the user performs operations such as print output, copy output, screen switching, and screen scrolling of information displayed on the monitor 8. This is information output from the information selection input means 2 based on the information. In other words, if the access display information 18 is generated, the user is interested in this information and can be said to be the desired information. Further, the fact that the confirmation signal 19 is generated for a certain time or more means that the user is interested in the display information. If it is not the desired information, the user inputs information for obtaining other information into the information selection input means 2. Therefore, if the duration of the confirmation signal 19 is determined, the user desires it. It is possible to determine whether or not the information that has been obtained can be obtained.

  When the confirmation information 19 continues for a certain period of time, or when the user is accessing the information displayed on the monitor 8, the access history management means 4 first identifies the user temporarily stored in the memory 4b. The interest level of the information classification designated by the classification designation data in the access history information of the user specified by the information is updated (step 310). That is, the interest level for the information classification corresponding to the corresponding user is called from the memory 4b and updated in a direction to increase the interest level. The new interest level obtained by the update is stored in the memory 4b as access history information in association with the corresponding information classification. Step 310 and the processing as described above are processing for learning a classification in which the user is interested based on the access information of the user. Details of how to calculate the interest level in the update will be described later. If the access history information of the user has not been created yet, the access history management means 4 creates it at this time. In addition, when there is no information classification item specified by the classification designation data in the access history information, the information classification item is created in the access history information at this time, and the obtained interest level is registered in the memory 4b. To do.

  On the other hand, if the confirmation information 19 does not continue for a certain period and the user does not access the information displayed on the monitor 8, the access history management means 4 does not update the access history management information. The user identification information and the classification designation data temporarily stored in the memory 4b are cleared and the process is terminated.

  In step 303, if the access information classification means 3 for each user determines that the mode specified by the request information from the information selection input means 2 is the automatic mode, the access information classification means for each user. 3 outputs only the user identification information for identifying the user to the access history management means 4 (step 312). Receiving this, the access history management means 4 refers to the access history information (stored in the memory 4b) for the user specified by the user identification information, and is most interested in the plurality of information classifications for the specified user. Information classification with a high degree is output to the interest information selection means 5 as classification designation data (step 313). This information category with the highest degree of interest is an information category in which the user is interested.

  The interest information selection means 5 searches for information belonging to the received information classification, and retrieves the searched information from the information source 6 (step 314). Step 314 functions as a means for extracting information belonging to the category from the information source based on the category of interest of the user learned in step 310 in the past.

  After that, when information belonging to the information category with the highest degree of interest does not exist in the information source 6 in step 307, it is determined that there is no corresponding information, and information indicating that is output to the editing means 7. The operation similar to the operation steps 307 to 311 in the manual mode described above is performed except that the classification designation data need not be cleared in step 311.

  It should be noted that the determination as to whether or not information belonging to the corresponding information class exists in the information source 6 is, for example, a key that matches or partially matches the keyword assigned to the information class for the information in the information source 6. It can be realized by attaching a word keyword and determining whether or not there is a word that matches the keyword assigned to the information classification.

  Here, as described above, how to obtain the interest level of each information classification of access history information provided for each user will be described.

  First, the first method is to find out how often the user has accessed the information belonging to each category for each information category, and use this as the degree of interest in the information category. is there. In this case, for example, the interest level value is increased in step 310. Alternatively, in step 310, the time when the user accessed information belonging to the information classification is recorded in the access history information, and in step 313, the number of accesses in the past fixed period is used as the interest level. Alternatively, in step 310, the time when the user accesses the information belonging to the information classification is recorded in the access history information, the number of accesses within a predetermined period in the past is periodically obtained, and the degree of interest is updated with this value. Like that.

  Next, the second obtaining method is a method in which the frequency obtained in the first obtaining method is weighted in advance for each information classification, and this is used as the degree of interest. Such weights are appropriately determined according to the usage mode of the information service system, such as when there is an information category that is particularly interesting or when there is an information category that the user wants to use.

  The third method is to configure the access history management means 4 using a neural network. This method will be described together with a specific example in a second embodiment to be described later.

  As described above, according to the first embodiment, if information is used in both the manual mode and the automatic mode, the degree of interest in the information classification to which the used information belongs is increased for the user, and thereafter When the user tries to obtain information in the automatic mode, information belonging to an information category with a high degree of interest can be presented automatically.

  In the above description, the user-specific access information classifying unit 3 determines the information class to which the specified information belongs. However, the user may input the information class directly from the information selection input unit 2. Good.

  In addition, when information is updated or added to the information source 6 when the automatic mode is specified, the interest level of the information classification to which the information belongs and the interest level of the information classification to which the currently used information belongs. If the information classification to which the updated or added information belongs is higher in interest, the updated or added information is displayed on the monitor 8 instead of the currently used information. Also good. Also, in this case, the interest information selection means 5 refers to the access history management means 4, adds an information selection reason to the information selected from the information source 6 and outputs it to the editing means 7, and the editing means 7 For example, if the information selection reason is displayed on the monitor 8 with the screen configuration shown in FIG. 4, the user can be notified of the reason for selecting the information, and the user is not confused. Here, the information selection reason includes information classification, the degree of interest of the user with respect to the information classification, and the like.

  In addition, when information belonging to an information category having a higher degree of interest than the information category to which the current display information belongs is updated or added to the information source 6 when the automatic mode is designated, an index of the information is displayed. Switching of information to be displayed may be accepted.

  In steps 307 and 308 (see FIG. 3), in the automatic mode, the interest information selection means 5 adds the information selection reason to the information selected from the information source 6 and outputs it to the editing means 7. The reason for selecting the information may be displayed on the monitor 8. In this way, it is possible for the user himself / herself to automatically know what information is of high interest to the user, and the user is selected by presenting the reason for selection. You can easily understand what kind of information the information is.

  In the above description, the interest level of each information classification is managed for each user. However, the interest level of each information classification may be managed for each user for each usage situation. The usage status information is, for example, the day of the week, the time zone, the user's mood at the time of use, the reason for accessing the information for what purpose, and the like. That is, the information selection input means 2 also receives or observes the usage status in step 301 at the time of manual mode designation or automatic mode designation, and the access information classification means for each user. 3, the access information classification means 3 for each user sends the classification designation data including the usage status, and the access history management means calculates and manages the interest level of each information classification for each user. The information is selected from the information source 6 at the time of use, and the information is selected from the information source 6 in the automatic mode. The user monitors information belonging to the information category having the highest degree of interest in the current use situation. 8 is displayed. As a result, it is possible to obtain and manage how much interest the user has in each information classification under each situation, and in the automatic mode, information corresponding to the situation at the time of use can be provided. . For each user, access management information for managing the degree of interest for each field (see FIG. 2) and access management information for managing the degree of interest for each information classification are provided in a hierarchy, and the degree of interest is hierarchized. May be managed.

  The interest level input means 60 functions when the user operates a predetermined key (for example, a key clearly indicating the level of interest) of a keyboard provided on the terminal. When the user is interested in information on the information classification that has been low in interest until now, the interest level input means 60 can be used to update the interest level data stored in the memory 4B. If such a function is not provided, in the manual mode, information that the user is newly interested in can be retrieved and provided from the information source 6, but this is not possible in the automatic mode. This is because the degree of interest in the information category newly interested in the memory 4B is low, so even if the user specifies information corresponding to the information category, steps 312 to 314 and 307 to 309 are performed. This is because information on another information category having a high degree of interest is retrieved from the information source 6 and provided to the monitor 8 by the processing. The above-mentioned problem is solved by the interest level input means 60 and the processing related to the means 60.

  That is, the interest level input means 60 works by the predetermined key operation. The degree-of-interest input unit 60 extracts all information classifications for the corresponding user based on the user identification information input from the keyboard and data on the degree of interest for these information classifications from the memory 4B and outputs them to the editing unit 7. A command signal is output to the access history management means 4. The editing means 7 outputs all information classifications output from the access history management means 4 and interest level data for these information classifications to the monitor 8. The user designates the information category to which the newly interested information belongs among the information categories displayed on the monitor 8 by using an input means such as a mouse or a light pen. Further, the user can select the menu items “increased interest” and “decrease interest” displayed on the monitor 8 until the interest level of the designated information category becomes the highest as compared with the interest levels of the remaining information categories. Among them, the former “increased interest” continues to be indicated by the mouse. This increase in interest can be stopped at any level by stopping the instruction from the mouse. When the “decrease interest level” menu item is designated, the interest level of the specified information classification decreases. The interest level input means 60 performs the process of specifying the information class with new interest and setting the interest level for the specified information class by the above operation. The designated information classification and the interest level data for this information classification are transmitted to the access history management means 4. The access history management means 4 updates the degree of interest for the designated information classification stored in the memory 4B based on the designated information classification and the interest level data for the information classification.

  Therefore, even in the automatic mode, the information that the user is newly interested in can be easily retrieved from the information source 6 and provided to the monitor 8 by the processing in steps 312 to 314 and 307 to 309.

  The access history reset means 70 executes the following processing. Similarly to the interest level input means 60, the access history reset means 70 is operated by a user operating a predetermined key (for example, a key clearly indicated as reset) on the keyboard. The access history reset unit 70 outputs a command signal to the access history management unit 4 in the same manner as the interest level input unit 60 based on the user identification information that is input from the keyboard. As a result, all the information classifications for the corresponding user and the interest level data for these information classifications are retrieved from the memory 4B, and output to the monitor 8 by the editing means 7 and displayed. The user designates, using a mouse or the like, an information category whose interest level is to be reset among the information categories displayed on the monitor 8. The access history resetting means 70 sets the interest level of the information classification whose interest level is to be reset to zero, and transmits this value to the access history management means 4. The access history management unit 4 updates the interest level of the information classification stored in the memory 4B to zero. In this way, the interest level of information classification and access history information in the memory 4B can be reset, and provision of information that the user is no longer interested in can be prevented.

  Next, the operation when the interest information index presenting means 9 of the information service system according to the first embodiment is used will be described.

  When there are a plurality of information belonging to the information class with a high degree of interest of the user, or when there are a plurality of information classes with a high degree of interest of the user, the access history management means 4 Display the index on the monitor. When an index of information that the user wants to use is selected from a plurality of displayed indexes, the index of interest is received from the interested index presenting means, and the information corresponding to this index is selected from the information source 6. An information classification with a high degree of interest of the user is an information classification in which the user is interested.

  Specifically, in the automatic mode, the access history management unit 4 determines one or a plurality of information classifications (a plurality of user interests) in which the degree of interest of the user specified by the user identification information is higher than a certain level. Is output to the interest information selection means 5. When the information source 6 has information belonging to one or more specified information classifications, the interest information selection means 5 stores the index of all the corresponding information in the access history management means 4 for each information classification. Return as. The interest information selection means 5 includes means for extracting information belonging to the classification from the information source based on the information classification (classification specified by the classification designation data) that the user is interested in, and at least one information classification. On the other hand, when there are a plurality of pieces of information to be extracted, there is provided means for outputting each index corresponding to each piece of information.

  Here, the index may be assigned to the information in advance, or the interest information selection means 5 may assign the index. As an example of assignment by the interest information selection means 5, an information title or a predetermined number of characters of the information title may be used as an index, or a specific number of keywords may be selected according to the information and used as an index. That's fine.

  The access history management means 4 takes the index information 20, adds the interest level of the information classification to which the information corresponding to the index information belongs to the index information, and the interest degree to the editing means 7 and the interest information index presentation means 9. The index information 14 is output. The editing means 7 displays the input index specified by the index information on the monitor 8.

  The index is displayed on the monitor 8 in a form in which the degree of interest of the information classification to which the information corresponding to each index belongs is known. For example, as shown in FIG. 5, indexes are displayed in order of highest interest, or numbers indicating interest (for example, 1 for the highest, 2 for the second highest, etc.) It is displayed at the beginning, or the index color is changed according to the degree of interest.

  Next, when the editing means operates the cursor displayed on the monitor 8 via the information selection input means 2 to select a desired index on the display, this information is input by the information selection input means 2. The The information selection input unit 2 outputs this information to the interest information index presentation unit 9 and the editing unit 7. The editing means 7 executes processing such as lighting the selected index according to this information.

  On the other hand, the interest information index presenting means 9 outputs soot index selection information 13 for designating the selected index to the access history managing means 4. The access history management unit 4 outputs the index selection information to the interest information selection unit 5. The interest information selection means 5 selects information corresponding to the index specified by the index selection information from the information source 6 and outputs the selected information 15 to the editing means 7. The editing means 7 outputs the information to the monitor 8. Furthermore, the access history management unit 4 updates the interest level of the information classification to which the information corresponding to the index of the access history information of the user belongs.

  In addition, after the index is displayed on the monitor 8, if there is no selection operation from the user even after a predetermined time has passed, the access history management unit 4 sends the index information to the interest information index presentation unit 9 and the editing unit 7. 14 to stop the output. As a result, the index displayed on the monitor 8 is deleted.

  However, after this, if the user inputs information to the information user identification determination means 1 for user identification, the index is output to the monitor 8 again in accordance with the above-described processing. Further, when an instruction for index display is input from the information selection input means 2, the information selection input means 2 adds this information to the access display information 18 and outputs it to the access history management means 4 and receives it. The access history management unit 4 may output the index information 20 to the editing unit 7 again and display it on the monitor 8.

  As described above, when the interest information index presenting means 9 is used, when there are a plurality of information classifications with a high degree of interest of the user or there are a plurality of information corresponding to the information classifications, an index indicating an overview of these information Can be presented and selected by the user.

  The access history information 16 and the index information 14 to which the degree of interest is added negatively are output to an external device via the output means 21 to determine what information each individual user is interested in. It becomes possible to grasp. For example, if this information is stored in a portable floppy or memory card via the output means 21 and is read by an external device, the user can be interested in each individual user in the external device. You can grasp and analyze the information you have. Further, the output information of the output means 21 may be transmitted to another device via the communication system.

  In any case, if you use this information in the commercial field, you can understand what category of information you are interested in by individual, so you can send advertisements for products related to information categories with a high degree of interest, It is possible to find information classification with a large number of high users, and take measures such as sales of products related to information parts with high interest level and reinforcement of advertisements. It is also possible to actively provide interesting information by applying the same to the mass media field. In other words, product sales and product advertisements based on market trends are possible.

  For the detection of information categories with a large number of users with a high degree of interest, the interest level of each user is evaluated for each information category, and by searching for information categories with a large number of users with a high degree of interest, I can grasp.

  Even when the interest information index presenting means 9 is used, the degree of interest may be managed and processed for each use situation described above.

  Next, the operation of the information service system according to the first embodiment when using the template access information storage means 10 will be described.

  The model access information storage unit 10 stores model access information indicating a model of information classification to be used by each user or a user belonging to a specific group. This template access information is the item information of the information classification to which the information necessary for obtaining specialized knowledge in a specific field belongs, and is necessary for obtaining general knowledge about various fields. It may be item information of information classification to which various information belongs. The contents are determined by the purpose the user is trying to obtain information.

  The model access information can also be stored in a portable information medium such as a memory card, ROM card, floppy disk, etc., and provided to the information service system. It is also possible to take in the template access information into the template access information storage means 10 using a communication system or the like.

  Now, FIG. 6 shows an operation flow when the template access information storage means 10 is used.

  The model access information storage unit 10 inputs the user identification information from the user identification determination unit 1, selects the model access information for the user specified by the user identification information, and sends the model access information to the comparison unit 11. The access information 17 is output (step 602).

  On the other hand, the access history management means 4 does not supply the information classification to the interest information selection means 5 and the user identification from the user identification determination means 1 when the shortage information presentation is designated by the activation means. Information is input, and access history information for the user specified by the user identification information is output to the comparison means 11 (step 602).

  The comparison means 11 inputs the template access information 17 and the access history information 16 and compares them (step 603). Specifically, in the access history information 16, the classification designation data having a high degree of interest is compared with the template access information. The individual shortage information 12 is based on the comparison result of the comparison unit 11 and is an information classification item (not user-interested) in the access history information that is not high in the information classification items included in the template access information. (Information classification excluding the information classification) having the information classification, and the information classification item is output to the editing means 7 as insufficient information for the user (step 604).

  The editing means 7 displays the information classification item specified by the received shortage information on the monitor 8.

  Here, since the shortage information displayed on the monitor 8 is information indicating what kind of information classification is lacking for the user, the user can view the shortage information displayed. It becomes possible to easily grasp information items and information fields that are lacking for me. Therefore, by obtaining this missing information after that, it is possible to obtain information of information classification adapted to the model indicated by the template access information selected by the user. Such a function is very useful for improving the knowledge of the user, and is suitable for application to an individual (or group) support system such as an education system.

  Hereinafter, an application example of the information service system according to the present invention to a television system will be described as a second embodiment of the present invention. That is, this is a case where the information of the information source is one program.

  FIG. 7 shows a configuration of a television system according to the second embodiment.

  As shown in the figure, the television system according to the second embodiment includes a television 38, a video signal storage means 41, a remote controller 30 for controlling them, a remote controller 42 for copying or receiving information stored in the remote controller 30, and a survey terminal. 43.

  The external appearance of the remote control 30 of FIG. 8 is shown.

  As shown in the figure, the remote controller 30 has various keys, a memory card port for mounting a memory card, an output terminal for the remote controller 42 or the survey terminal 43.

  The television 38 receives the video signal of the antenna 37 and selects the tuner 39, the channel selection means 36, or the control signal of the channel selection means in the television, the output signal of the tuner 39 or the output signal of the recording device 41. An output means 40 for outputting one of the signals to the editing means 7A, an editing means 7A for editing information from the remote controller 30 and an output signal from the output means 40, and a monitor 8A for displaying the output signal of the editing means 7A. Have.

  The remote controller 30 includes a program memory card 32, an OR input means 44, a program information storage means 33, a user-specific access information classification means 34, an access history management means 4A, a user identification determination means 1A, a channel selection input means 35, interest information. Index presentation means 9A, channel selection means 36, output means 21A, template access information storage means 10A, comparison means 11A, individual shortage information determination means 12A, activation means 22, classification series selection means 63, interest level input means 60 and Access history reset means 70 is provided.

  In the second embodiment, program information for several weeks is stored in the program memory card 32 and mounted on the remote controller 30. The program information in the program memory card 32 is stored in the program information storage means 33 via the OR input means 44 all or one week.

  In the second embodiment, each broadcasting station broadcasts program information in addition to video information. This television system receives program information received by an antenna 37 and a tuner 39, and program information by a tuner 39. Each time it is detected, it is stored in the program information storage means 33 in the remote controller 30 via the OR input means 44. For example, if the program information to be broadcast is one week's worth of program information, one week's worth of program information stored in the program information storage means 33 in the remote controller 30 every time the tuner 39 receives the information. Is updated via the OR input means 44. If each broadcast station transmits program information broadcast by all broadcast stations, the tuner can detect the program information regardless of which program is selected.

  The program information includes information such as a program name, a broadcast date, a broadcast time zone, and a classification to which each program belongs.

  The user identification determination means 1A is a means for determining who is using the television. As shown in FIG. 8, the user is identified by providing the remote controller 30 with a key group 800 assigned to each user, and identifying the user according to this key operation. However, each method of user identification as described in the first embodiment may be used.

  The channel selection input unit 35 accepts designation of a mode, which will be described later, and designation of channel selection. The channel selection means 36 and the tuner 39 specify the program received, the video signal storage means specifies the program to be stored or reproduced, and the video signal output from the output means is selected. The classification series selection means 63 accepts designation of the classification for which the degree of interest is calculated and managed.

  User-specific access information classification means 34, access history management means 4A, user identification determination means 1A, interest information index presentation means 9A, output means 21A, model access information storage means 10A, comparison means 11A, individual shortage information determination The means 12A, the activation means 22, the interest level input means 60, and the access history reset means 70 have the same functions as the components of the same name in the information service system according to the first embodiment, and therefore description thereof is omitted.

  The operation of the television system according to the second embodiment will be described below.

  First, the operation when the interest information index presenting means 9A and the model access information storage means 10A are not used will be described.

  FIG. 9 shows an operation flow in this case.

  As shown in the figure, in this case, first, the user identification determination unit 1A determines the user by the above-described method (the process of step 301) according to the key group 800 assigned to each user, and the determination is made. The obtained user identification information for identifying the user is output to the user access information classification means 34 (step 901). The channel selection means 35 receives input of three keys “automatic” 801, “channel selection” 802, and “manual” 803 of the remote controller 30 shown in FIG. Output (step 902). The access information classification unit 34 for each user determines whether the mode designation is the automatic mode, the channel selection mode, or the manual mode from the result acquired from the information selection input unit 35 (step 903).

  Here, the automatic mode is a mode in which the television system automatically selects a program desired by the user. For this reason, in the automatic mode, the user only has to input information for identifying the user and information indicating the automatic mode. Next, the channel selection mode is a mode in which a user selects a program directly. In the channel selection mode, the user selects a channel using the channel key 804, and the television system learns the degree of interest of the user according to the program corresponding to the selected station. In addition, the manual mode is a mode for simply selecting a channel using the channel key 804 by the user. In this mode, the channel is selected. do not do.

  First, when the mode determined in step 903 is the channel selection mode, the user-specific access information classification unit 34 refers to the program information storage unit 32 and the user identification determination unit 1A uses the channel key 804. The classification designation data for designating the classification to which the program broadcast on the accepted station belongs is created and output to the access history management means 4A together with the user identification information for identifying the user input in step 901 (step 904). . The access history management means 4A takes in the information (user identification information and classification designation data) from the user-specific access information classification means 34, and temporarily stores these information in the memory 4b (step 905). The channel selection means 36 is a tuner 39 of the television 38 or a user 41A (of the recording apparatus 41) so as to select a program belonging to the classification specified in the classification designation data output from the user-specific access information classification means 34. FIG. 16) is controlled (step 906). Tuning by such a tuner is to extract information on a program specified by the classification designation data from a plurality of information transmitted from a plurality of broadcasting stations which are information sources. In step 906, the channel selection means 36 also controls the output means 40.

  The editing means 7A outputs the video signal obtained by channel selection and input from the output means 40 to the monitor 8A (step 907).

  On the other hand, the access history management unit 4A outputs the information for channel selection to the channel selection unit 36, and there is no other operation input for a certain period of time, or the channel selection input unit outputs the operation by the user of the OK key 805. It is determined whether the acknowledgment information 18A to be output has been output (step 908). This is a function for determining whether the selected program is what the user wants to watch. In any of the above cases, it is determined that the user has obtained the program that he / she wants to watch. To do. When the user agrees with the displayed program, the user operates the OK key.

  The access history management unit 4A has a positive determination result in step 908. That is, after the information for channel selection is output to the channel selection unit 36, there is no other operation input for a certain period of time, or the acknowledgment information 18A is output. If so, the interest level of the classification designated by the temporarily designated classification designation data in the access history information of the user designated by the user identification information is updated (step 909). Step 909 is a process of learning the classification in which the user is interested based on the access information of the user, as in step 310 described above. Details of access history information, program classification, and interest level learning used in the second embodiment will be described later.

  If the determination result in step 908 is negative, as shown in step 10, the access history management means 4A clears the classification designation data temporarily stored in the memory 4b and ends the operation (step 910).

  Next, when the mode determined in step 903 is the automatic mode, the access information classification unit 34 for each user outputs the user identification information to the access history management unit 4A (step 911). The access history management unit 4A reads the access history information of the user specified by the user identification information, determines the category with the highest degree of interest, and outputs the determined category to the channel selection unit 36 (step 912). The channel selection unit 36 refers to the program information storage unit 32, selects a station broadcasting a program belonging to the input category, and controls the tuner 39 and the output unit 40 so as to output to the editing unit 7A. (Step 915). Step 915 performs the same function as step 314.

  Thereafter, as in the channel selection mode, the processing of step 907, step 908, and step 909 is performed and the processing is terminated.

  On the other hand, when the mode determined in step 903 is the manual mode, the user-specific access information classification unit 34 outputs the channel selection content to the channel selection unit 36 (step 913), and the channel selection unit 36 is designated. The tuner 39 and the output means 40 are controlled so that the selected station is selected and output to the editing means 7A (step 914), and the process is terminated.

  In the second embodiment, as in the first embodiment, when the automatic mode is designated, the program information storage means 32 is referred to and it is time to start broadcasting a new program. Compare the interest level of the category to which the program belongs and the interest level of the category to which the currently displayed program belongs, and if the interest of the category to which the program that starts broadcasting is higher, broadcasting starts The program may be switched to the program to be displayed on the monitor 8. Alternatively, when the automatic mode is designated, the program information storage means 32 is referred to, and when it is time to start broadcasting a new program, the interest level of the category to which the program belongs and the currently displayed program If the interest level of the category to which the program belongs is compared, and the category to which the program to be broadcast belongs has a higher interest level, the program name of the program to be broadcast is displayed on the monitor 8, and the candidate key 809 is displayed. When the designation of switching is accepted by the above operation and the designation of the next candidate program is accepted, the channel selection may be switched to the program to start broadcasting, and the display on the monitor may be performed. Further, in these cases, etc., when the channel selection means 36 performs channel selection in the automatic mode, the program selection reason is always displayed on the monitor 8A by superimposing it on the video with the screen configuration as shown in FIG. The user can be notified of the reason for selecting the program, and the user is not confused. In this case, the access history management means 4A passes the program classification, the degree of interest of the user with respect to the program classification, etc. to the editing means 7A and includes them in the program selection reason to be displayed.

  In addition, the access history management means 4A refers to the program information storage means 33, and shows the next highest degree of interest next to the name of the currently broadcast program belonging to the same category as the selected program and the category to which the selected program belongs. The name of the currently broadcast program belonging to the category may be passed to the editing means 7A, and the editing means 7A may superimpose it on the video and display it as the next candidate as shown in FIG. Then, the designation of the next candidate program by the operation of the candidate key 809 is accepted, and when the designation of the next candidate program is accepted, the channel selection is switched to the next candidate program and the display on the monitor is performed. May be. Such display and selection of the next candidate can be similarly performed in the first embodiment by using the above-described index instead of the program name.

  When the reset key 815 of the remote controller 30 is pressed, the access history reset means is activated, and the process for resetting the interest level as described in the first embodiment is executed.

  Here, as described above, details of learning of access history information, program classification, and interest level used in the second embodiment will be described.

  First, access history information and program classification will be described.

  An example of access history information provided for each user is shown in FIG.

  As shown in the figure, the access history information shown in FIG. 11 is the access history information of the user A 1103, and the user's interest level 1102 for each classification 1100 is registered for each broadcast time zone 1101. That is, the use time zone is used as the use situation. As the usage time zone, the observed usage time zone is observed so that the user-specific access information classification means 34 outputs the classification designation data, and the access history management means manages the degree of interest for each time zone. To. In addition to the time zone, the day of use may be included in the classification designation data, and the degree of interest may be managed and processed for each day of the week.

  In this example, a small genre such as English (education) or baseball (sports) provided for each large genre such as education or sports is used as a classification of programs.

  However, these classification methods may be different for each user. That is, one category is assigned to each program, the large genre is classified into one category, for example, sports programs are classified into women's sports and boys' sports, and ball games and other sports are classified. It may be. In this case, models for some classification examples are stored in advance in the access information classification means 34 for each user, and each model is displayed on the monitor 8A via the access history management means 36 and the editing means 7A. In the above, each user is made to select a model with the classification sequence selection key 806, and the classification sequence selection means 63 is registered with the user in the access information classification means 34 for each user. .

  Note that a key for inputting the above-described usage situation may be provided on the remote controller, the degree of interest may be managed for each input usage situation, and the process using the degree of interest may be performed for each usage situation. 12 and 13 show an example in which the degree of interest is managed for each usage situation by providing access history information for each usage situation of the user. The examples shown in FIGS. 12 and 13 are examples in the case where the user's mood 1201 is used as a usage situation.

  Next, details of the interest level learning method used in the second embodiment will be described.

  Also in the second embodiment, as in the first embodiment, by increasing the interest level value of the corresponding category in step 909, the frequency of access to the category is obtained, and this may be used as the interest level. The access time may be recorded in the access history information, and the number of accesses in the past fixed period may be used as the degree of interest. The obtained frequency is weighted in advance for each information classification, It may be the degree of interest. In this case, the access information classification means 34 for each user displays the classification used by the user on the monitor 8A via the access history management means 36 and the editing means 7A, and the interest level is indicated to each user on the display. The input key 807 is used to set the weight of each classification. The interest level input unit 60 registers the weight of each classification set by the interest level input key 807 in the access history management unit 4A. The access history management unit 4A performs weighting using the weight registered in the frequency. Further, such a weight may be a weight that determines a selection priority when a plurality of classifications having the same frequency exist.

  Further, as described above, the access history management means may be configured using a neural network, and the degree of interest may be learned thereby. Hereinafter, this case will be described.

  FIG. 14 shows a configuration of a neural network system for storing and learning access history information provided in the access history management means 4A. The configuration of FIG. 14 performs the processing of step 909 of the second embodiment. In the figure, 402 and 404 are switching means, 403A to 403N are neural networks provided for each user, and 405 is a learning control means.

  Since the neural network itself is a generally known technique as described in, for example, The MIT Press Parallel Distributed Processing, 1988, 7th edition, pp 318 to 362, detailed description is omitted.

  Each input 4011 to 401i of each neural network corresponds to each classification used by the corresponding user. For example, the input 4011 of the neural network 403A of the user A using the classification shown in FIG. The input 4012 corresponds to the classification “French”. The outputs 4021 to 402i also correspond to the classifications used by the corresponding users. For example, the output 4021 of the neural network 403A of the user A that uses the classification shown in FIG. 11 corresponds to the classification “English”. The output 4012 corresponds to the classification “French”.

  Now, at the time of the channel selection mode or when the interest level is updated in the automatic mode (step 909), the access history management means 4A performs such learning of the neural network as follows. When the user identification information designates user A, the switching control means 402, 403 selects the neural network 403A corresponding to user A. Then, if the determination result in step 908 is positive, that is, there is no input of another operation for a certain period after the information for channel selection is output to the channel selection means 36, or the acknowledgment information 18A is output, or When a program is selected using an index, which will be described later, the learning control unit 405 refers to the program information storage unit 32 based on the signal 430, and inputs 4011 of the selected neural network 403A. ˜401i, the value corresponding to the category to which the currently broadcast program belongs is value 1, the others are value 0, and among the outputs 4021 to 402i, the output value corresponding to the category to which the selected program belongs. 1 is created, and learning data with other output values of 0 is created and stored. Then, the neuro-network is learned using the learning control signal together with the learning data created in the past. In this way, the degree of interest in each category is learned by giving an actual program selection example to the neural network. Specifically, the neural network determines the weight inside the neural network connecting the input and the output based on the given example of the input and the output. Note that the learning data used for learning may be only the learning data created this time and the learning data for a certain period in the past from the present time.

  In the automatic mode, the access history management means 4A uses such a neural network when obtaining a classification with a high degree of interest of the user in step 912 or when obtaining a classification with a high degree of interest of the user using an index described later. Let the network learn as follows. When the user identification information designates user A, the switching control means 402, 403 selects the neural network 403A corresponding to user A. Then, the access history management unit 4A refers to the program information storage unit 32, and sets the value corresponding to the classification to which the currently broadcast program belongs among the inputs 4011 to 401i of the selected neural network 403A, The other values are 0. Receiving this input, the neural network 403A outputs to the outputs 4021 to 402i a value corresponding to the already learned content, that is, the determined internal weight. For example, a value corresponding to the learned degree of interest such as a value of 0.7 for an output corresponding to the category “English” being broadcast, and a value of 0.4 for an output corresponding to the category “French” being broadcast. Is output. Also, the value 0 is output to the output corresponding to the classification that is not being broadcast.

  The learning control means determines and outputs a classification having a higher degree of interest of the user than these outputs or a classification higher than a certain value.

  As described above, such a neural network can be applied to the first embodiment. In this case, a neural network may be provided for each field. Further, in the first and second embodiments, the use situation and day of the week may be added to the input, but a neural network may be provided for each use situation and day of the week.

  Next, the operation when the interest information index presenting means 9A of the television system according to the second embodiment is used will be described.

  The operation in this case is substantially the same as the operation in the case where the interest information index presenting means 9 is used in the information service system according to the first embodiment.

  The difference is that the information is a program, the index is a program name, and the index is obtained from the stored contents of the program information storage means 33.

  Specifically, the access history storage unit 4A is a program that belongs to a category of a high degree of interest under the specified usage status of the user, and the program information storage unit 33, the degree of interest of the classification to which the program belongs is added to this, and the index information 14A with the degree of interest is output to the editing means 7A and the interest information index presenting means 9A. In addition, the user's selection of a program using the displayed index is received by the channel selection input means 35 by operating the candidate key 809 of the remote controller 30.

  In the television system according to the second embodiment, instead of an index, a program belonging to a category of a high degree of interest under the specified usage status of the user, and a program of a program currently being broadcast May be displayed on the monitor 8A. In this case, n programs are selected in order from programs belonging to the category with higher interest level, and each child screen obtained by dividing the screen of the monitor 8A into n child screens belongs to the category with higher interest level. In order, the video of the program is displayed. Then, the selection of the program is accepted on the display.

  The access history information 16 and the index information 14A to which the degree of interest is added are output to another remote controller by the output means 21A via the output terminal 810 of the remote controller, whereby the program information that the individual is interested in is transmitted to the other remote controller. It becomes possible to transplant. Further, similar to the information service system of the first embodiment, these pieces of information may be transmitted to the survey terminal 43.

  Next, the operation of the television system according to the first embodiment when using the template access information storage unit 10A will be described.

  The operation of the television system in this case is shown in FIG. As shown in the figure, the information service system according to the first embodiment except for the point that the operation using the template access information storage means 10A is activated by the template activation key 811 of the remote controller 30 and the information is a program. Since it is the same as the operation when the template access information storage means 10 is used, the description thereof is omitted.

  Next, in the second embodiment, an operation of recording a program with a high degree of interest of the user in the recording device 41 and an operation of reproducing a program with a high interest of the user recorded in the recording device 41 will be described.

  First, when a program with a high degree of interest of the user is stored in the recording device 41, the VTR 812, the recording 813, and the automatic 801 key of the remote controller 30 are pressed, and the user is specified with the user key 800. Information by these operations is input to the user identification determination unit 1A and the channel selection input unit 35. Thereafter, by the same operation as in FIG. 9, the program being broadcast belonging to the category with the highest degree of interest of the user is selected. Thereafter, as shown in FIG. The tuner 41A is given a channel selection signal 41C for designating a station that broadcasts the broadcasted program, and a program with a high degree of interest of the user is selected. Further, the recording means 41B is controlled by the recording signal 41D to record this program. As a storage medium used in the recording unit 41B, various information storage media such as a tape, a floppy disk, and an optical disk can be applied. When recording the program, the recording unit 41B outputs an address 45 indicating in which part of the storage medium the program is stored to the channel selection unit. The channel selection means 36 stores the address, the recorded program, and the interest level of the category to which the program belongs in association with each other.

  Next, when the recorded program is reproduced, the VTR 812 and reproduction 814 keys of the remote controller 30 are pressed, and the user is specified by the user key 800. When such an operation is accepted, the channel selection means 36 outputs, to the reproduction means 41E, the address corresponding to the program corresponding to the highest degree of interest among the recorded programs as the reproduction signal 41F. . The reproduction unit 41E creates information specified by the reproduction signal 41F among the information that is recorded so as not to be stored by the recording unit 41B, and outputs the information to the output unit 40. Further, the channel selection means 36 controls the output means 40 so that the reproduction means 41E outputs the reproduced information signal to the editing means 7A. On the other hand, when the storage means 41B receives this signal, it reproduces the program from the received address and outputs it to the output means 40. As a result, the program having the highest interest level among the recorded programs is reproduced for the user and displayed on the monitor 8A. The reproduction of the next candidate recorded program is accepted by inputting the candidate key 809 of the remote controller 30. Alternatively, the next candidate recorded program is automatically played after the end of playback.

  As described above, according to the television system of the second embodiment, the user can record a program belonging to a category with a high degree of interest and can view it whenever he / she likes it.

  Next, the survey terminal 43 will be described.

  FIG. 17 shows the configuration of the survey terminal 43.

  The access history storage unit 4A in the remote controller 30 outputs the classification of programs with a high degree of interest for each individual to the survey terminal 43 by the output unit 21A via the output terminal. This information is stored in the transmission data storage means 52 via the transmission means 51 and then stored in the market trend research storage means 53. This stored information is stored in a floppy via the output means 55 or processed in a processing center via a transmission system such as a telephone line, and who is interested in what kind of program, It is used to determine what kind of program is generally viewed as a whole.

  On the other hand, the audience rating survey storage means 54 is a means for storing what category the program selected by the channel selection means 36 of the remote controller 30 belongs to. When the access history information as shown in FIG. 11 is used, information indicating what kind of program is selected at what time zone as shown in FIG. 18 instead of the classification for each user. Remember. In any case, if one program is classified into one category, information about each program can be obtained.

  As described above, according to the second embodiment, the information service system according to the first embodiment can be applied to a television system, and the same effects as in the first embodiment can be obtained.

  Next, a third embodiment of the present invention will be described with reference to FIG. The third embodiment is another example of the television system. The television 38A in the third embodiment includes an access history management means 4A, an interest information index presentation means 9A, a model access information storage means 10A, a comparison means 11A, and individual shortage information provided in the remote control 30 shown in FIG. The determination unit 12A, the output unit 21A, the program information storage unit 33, the user-specific access information classification unit 34, the channel selection unit 36, and the OR input unit 44 are added to the configuration of the television 38 of the second embodiment. The user identification determination unit 1A, the activation unit 22, the channel selection input unit 35, the interest level input unit 60, the classification series selection unit 63, and the access history reset unit 70 in the third embodiment are provided in the remote controller.

  As described above, the third embodiment has the same effect as the second embodiment, although the configuration is different from that of the second embodiment.

  In the fourth embodiment, the access history management means 4A, the interest information index presentation means 9A, the model access information storage means 10A, the comparison means 11A, the individual shortage information determination means 12A, the output means 21A, and the program information storage means 33 are described. In this embodiment, the access information classification means 34 for each user, the channel selection means 36 and the OR input means 44 are provided in the recording apparatus 41 instead of the television as in the third embodiment. In this embodiment, the same operation and effect as in the second embodiment can be obtained.

  In addition, although not shown, the fifth embodiment is a television in which the recording device 41 in which the recording device 41 is incorporated in the television 38A in the third embodiment shown in FIG. 19 and the television 38A are integrated. This embodiment can also obtain the same effects as those of the second embodiment.

  Further, in the above embodiment, the interest level is learned from the actual use situation, but the user may be able to directly set the interest level. For example, in the second embodiment, the interest level input unit 60 updates the contents of the access history information of the user in the access history management unit 4A according to the operation of the interest level input key 807 of the user's remote control 30.
