Description

Industrial applications

  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, a radio receiver, and the like.

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

  In such an information service system, as a technique for supporting the selection of information by a user, for example, Japanese Patent Application Laid-Open No. 3-284,077, entitled "Program Information Display and Control," The technique described in "Apparatus" is known.

  This technology displays television program information on a television receiver, and accepts instructions for program selection, program reservation, and recording on the displayed television program information. This alleviates the user's trouble of having to refer to a magazine in which a program column or a program guide is published.

  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 it is a technology that does.

  By presenting a list of information included in the information source, such as the technology described in Japanese Patent Application Laid-Open No. Hei 3-284077, the number of information included in the information source can be reduced by the technology that assists the user in selecting information. If the number of items is large, the number of items included in the list increases, so that there is a problem that the operation for finding the item of information desired by the user becomes complicated.

  Further, for example, when it is desired to uniformly provide information necessary for the education of a user to a user who is in an education stage, entrusting the user with all of the information selection may reduce the information to be used. There is a problem that bias occurs.

  An object of the present invention is to provide an information service system that can easily and appropriately provide information desired by a user.

  Another object of the present invention is to provide an information service system that can notify a user of insufficient information.

  A feature of the present invention that achieves the above object is a learning unit that learns a class in which the user is interested from the access information of the user, and information belonging to the class based on the learned class in which the user is interested. And an information selecting means for extracting and providing the information from the information source.

  A feature of the present invention that achieves the other object is that a means for storing a plurality of classifications to be used by a user, and the plurality of classifications stored in the storage means, the classifications that the user is interested in Means for retrieving and outputting other classifications except for.

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

  In addition, information that is insufficient for the user can be notified to 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 access information of the user, and information belonging to the class is determined based on the learned class in which the user is interested. Since the information is extracted and provided, the information desired by the user can be easily estimated, and the information desired by the user can be appropriately provided.

  Further, according to the information service system of the present invention, of the plurality of classes stored in the storage means to be used by the user, the other classes except for the class in which the user is interested are searched for and output. Therefore, information that is insufficient for the user can be notified to the user. For this reason, the user can easily obtain information on a new classification that he has not been aware of.

  Hereinafter, a first embodiment of the information service system according to the present invention will be described.

  FIG. 1 shows the configuration of the 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, an interest information determination unit 5, , Information source 6, editing means 7, monitor 8, interest information index presenting means 9, template access information storage means 10, comparing means 11, individual shortage information judging means 12, activation means 22, interest degree input means 60, and access A history reset unit 70 is provided.

  The user identification determining means 1 receives input of user identification information for accessing information and determines a user. As a method of user identification, assign operation keys to the user in advance, identify the user according to the depression of the operation key, and input personally-dependent information such as registered names and personal identification numbers. A method of accepting and identifying a user, a method of taking a fingerprint, collating with a fingerprint pattern registered in advance, and identifying a user can be adopted. Note that an ID card or the like can be used for inputting user identification information.

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

  The access history management unit 4 manages access history information indicating the degree of interest of each user in the information of each category. How to determine the degree of interest will be described later. At the time of the automatic mode, the interest information selecting means 5 takes out the information from the information source 6 according to the management contents of the access history managing means 4 (for example, the degree of interest in the corresponding user), and sends it to the editing means 7 as selection information 15. Output. At the time of the manual mode, the interest information selection means 5 extracts 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) storing a plurality of pieces of information classified into a plurality of categories, or a plurality of broadcast stations. The editing unit 7 edits the selection information 15 and displays the edited information content on the monitor 8.

  The interest level input means 60 inputs information on the interest level and information on the weight for obtaining the interest level 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 means 10 stores, for each user, a model of an information classification to be used by the user. When activated by the activation unit 22, the comparison unit 11 stores the model of the corresponding user 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. Compare with The individual shortage information judging means 12 judges the information lacking for the user based on the comparison result of the comparing means, and displays the classification of the information obtained by the judgment on the monitor 8 via the editing means 7. I do. The access history reset means 70 inputs the cancellation information of the access history information for each user stored in the memory 4b of the access history management means 4 by a user operation, and inputs the cancellation information to the access history information management means. 4 is output. Cancel information can be set for each user and each category.

  Now, as shown in FIG. 2, the information source 6 has a plurality of information items belonging to a plurality of information classifications such as a redundant configuration, a signal selection function, a transmission circuit configuration, a transmission coding system, clothes, and Japanese clothes. It is assumed that 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 composed of the fields of science and technology 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. By the way, when information of different fields is included as described above, the information source 6 may be realized as a set of information sources for each field.

  Hereinafter, the operation of the information service system according to the first embodiment will be described.

  First, an operation when the interest information index presenting means 9 and the template access information storing 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 service system inputs user identification information directly from the user or through a terminal or the like (not shown), the user identification determining means 1 identifies the user. Judgment is made and the user identification information for identifying the user obtained is outputted to the user access information classifying means 3 (step 301). Next, the information selection input means 2 receives request information for designating a mode and specifying information to be accessed from the user, and outputs the result to the user-specific access information classifying means 3 (step 302). In the first embodiment, the information service system is provided with two modes, an "auto mode" and a "manual mode". Only when the "manual mode" is designated, the user includes the designation of the information to be accessed in the request information. When the "auto mode" is designated, the information service system infers information of high interest from the user and automatically selects the information. Therefore, when the user designates the “auto mode”, the user only needs to input the identification information and the information indicating the automatic mode.

  Next, the user-specific access information classifying means 3 determines whether the mode specified by the request information from the information selection input means 2 is an automatic mode or a manual mode (step 303).

  When the manual mode is designated, the user-specific access information classifying means 3 outputs information specifying the designated information to the interest information selecting means 5 from the input request information. Also, the information classification to which the specified information belongs is determined, and the classification specification data specifying the determined information classification is created, and is 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 class to which the specified information belongs in the user-specific access information classifying means 3 is performed, for example, by assigning one or more keywords to each information class in advance and assigning each information to the information class to which the information belongs. -Assignment of a keyword indicating matching or partial matching with the word, accepting designation of information by the keyword, and selecting a keyword matching or partially matching the input keyword. The information classification can be performed by setting the information classification to be the information classification to which the information belongs. Specifically, for example, it can be realized by inference means having a conditional part and a conclusion part such as an if-then type.

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

  On the other hand, the interest information selection means 5 extracts from the information source 6 information belonging to the classification specified by the classification designation data output from the user-specific access information classification means 3 (step 306). After that, the interest information selecting unit 5 outputs the information extracted from the information source 6 to the editing unit 7 as the selection information 15, and outputs confirmation information 19 indicating that to the access history managing unit 4. If there is no designated information in the information source 6, the interest information selecting unit 5 determines that the corresponding information does not exist and outputs information indicating that to the editing unit 7 (step 307).

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

  On the other hand, the access history management means 4 determines whether the confirmation information 19 from the interest information selection means 5 has continued for a certain period of time, or the user has accessed the information displayed on the monitor 8 using the access display information 18. Is determined (step 309). This determination is for determining whether the information selected from the information source 6 is what the user has desired to obtain, and in any of the above cases, the user has obtained the desired information. That is, 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 an operation such as print output, copy output, screen switching, screen scrolling, etc. of the information displayed on the monitor 8. This is information output from the information selection input means 2 based on the information. That is, if the access display information 18 is generated, the user is interested in this information, and it can be said that the user has requested the information. The fact that the confirmation signal 19 has been generated for a certain period of time or more means that the user is looking at the display information with interest. If the information is not the desired information, the user inputs information for obtaining other information to the information selection input means 2. If the duration of the confirmation signal 19 is determined, the user can obtain the desired information. It can be determined whether or not the information that has been obtained can be obtained.

  If the confirmation information 19 has continued for a certain period of time, or if the user has accessed the information displayed on the monitor 8, the access history management means 4 first stores the user identification information temporarily stored in the memory 4b. The interest level of the information classification specified by the classification specification data in the access history information of the user specified by the information is updated (step 310). That is, the degree of interest in the information classification corresponding to the corresponding user is called from the memory 4b, and is updated in a direction to increase the degree of interest. 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. The processing in step 310 as described above is processing for learning a classification in which the user is interested based on the access information of the user. Details of how to determine the degree of interest in updating 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 point. If 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 degree of interest is registered in the memory 4b. I do.

  On the other hand, when the confirmation information 19 has not been continued for a certain period of time and the user has not accessed the information displayed on the monitor 8, the access history management means 4 does not update the access history management information, and Then, the user identification information and the classification designation data temporarily stored in the memory 4b are cleared, and the process ends.

  In step 303, when the user-specific access information classifying means 3 determines that the mode specified by the request information from the information selection input means 2 is the automatic mode, the user-specific access information classifying means. 3 outputs only the user identification information for identifying the user to the access history management means 4 (step 312). Upon 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 finds the most interesting information among a plurality of information classifications for the specified user. The information classification with a high degree is output to the interest information selection means 5 as classification designation data (step 313). The information category having the highest interest level is the information category in which the user is interested.

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

  After that, when the information belonging to the information class having the highest interest level does not exist in the information source 6 in step 307, the information indicating that the corresponding information does not exist is output to the editing unit 7. The operation in the manual mode described above is the same as that in steps 307 to 311 except that the classification designation data need not be cleared in step 311.

  The determination as to whether or not the information belonging to the corresponding information class exists in the information source 6 is made, for example, by matching a key assigned to the information in the information source 6 to the information class or partially matching the keyword assigned to the information class. 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, a method of obtaining the degree of interest of each information classification of the access history information provided for each user will be described.

  First, the first method is to determine, for each information class, how often the user has accessed information belonging to each class, and use this as the degree of interest in the information class. is there. In this case, for example, the value of the degree of interest is increased in step 310. Alternatively, in step 310, the time at which the user accessed the information belonging to the information classification is recorded in the access history information, and in step 313, the number of accesses within a certain period in the past is used as the degree of interest. Alternatively, in step 310, the time at which the user accessed the information belonging to the information category is recorded in the access history information, the number of accesses within a certain period in the past is periodically obtained, and the degree of interest is updated with this value. To do.

  Next, the second method is a method in which the frequency obtained in the first 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 a particularly interesting information class or when there is an information class that the user particularly wants to use.

  A 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 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 attempts to obtain information in the automatic mode, information belonging to an information category having a high degree of interest can be automatically presented.

  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 directly input the information class from the information selection input unit 2. Good.

  Further, when information is updated or added to the information source 6 when the automatic mode is designated, the degree of interest of the information class to which the information belongs and the degree of interest of the information class to which the information currently used belongs. If the information classification to which the updated or added information belongs has a higher degree of interest, the updated or added information is displayed on the monitor 8 instead of the currently used information. Is also good. In this case, the interest information selecting unit 5 refers to the access history managing unit 4 and adds the information selection reason to the information selected from the information source 6 and outputs the information to the editing unit 7. For example, if the information selection reason is displayed on the monitor 8 with the screen configuration as shown in FIG. 4, the user can be notified of the information selection reason, and the user is not confused. Here, the information selection reason includes the classification of information, the degree of interest of the user in the information classification, and the like.

  Also, when the information belonging to the information class having a higher degree of interest than the information class to which the current display information belongs is updated or added to the information source 6 when the automatic mode is designated, the 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 selecting means 5 adds the information selection reason to the information selected from the information source 6 and outputs the information to the editing means 7, and the editing means 7 Alternatively, the information selection reason may be displayed on the monitor 8. By doing so, it is possible for the user to automatically grasp what information is of high interest to the user, and the user is selected by presenting the reason for selection. It is easy to understand what kind of information the information is.

  Further, in the above description, the degree of interest of each information class is managed for each user. However, the degree of interest of each information class may be further managed for each use situation of each user. The information on the status at the time of use includes, for example, the day of the week of use, the time zone, the mood of the user at the time of use, the reason for accessing the information for what purpose, and the like. That is, in the manual mode designation and the automatic mode designation, the information selection / input means 2 receives or observes the use status together with the use status in step 301, and obtains the user-specific access information classification means. 3 and the user-specific access information classifying means 3 sends the classification designation data together with the situation at the time of use, and the access history management means calculates and manages the degree of interest of each information class for each user. The selection from the information source 6 in the automatic mode is performed by monitoring the information belonging to the information class having the highest degree of interest under the current usage state. 8 is displayed. This allows the user to obtain and manage the degree of interest in each information classification under each situation, and to provide information according to the usage situation at that time in the automatic mode. . Note that, 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 a user operates a predetermined key (for example, a key explicitly indicating the interest level) of a keyboard provided in the terminal. When the user is interested in the information on the information class having a low interest level, the interest level data stored in the memory 4B can be updated by using the interest level input means 60. If such a function is not provided, in the manual mode, the user can search for and provide information of new interest from the information source 6 but cannot do so in the automatic mode. This is because the degree of interest in the newly interesting information classification stored in the memory 4B is low, so that even if the user specifies the information corresponding to the information classification, the steps 312 to 314 and 307 to 309 are performed. This is because the information is retrieved from the information source 6 and provided to the monitor 8 for other information categories of high interest by the processing. The above problem is solved by the interest level input means 60 and the processing related to the means 60.

  That is, the interest input means 60 operates by the predetermined key operation. The interest level input means 60 retrieves, from the memory 4B, 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, and outputs the data to the editing means 7. It outputs a command signal to the access history management means 4. The editing means 7 outputs to the monitor 8 all information classifications output from the access history management means 4 and data on the degree of interest in these information classifications. The user designates the information category to which the newly interested information belongs to 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 selects the menu items of “increased interest” and “decreased interest” displayed on the monitor 8 until the degree of interest of the specified information classification becomes the largest relative to the degree of interest of the remaining information classifications. The former "increase in interest level" is continuously instructed by the mouse. This increase in interest can be stopped at any level by stopping the mouse instruction. When the menu item “decrease in interest level” is designated, the interest level of the specified information classification decreases. The process of designating a newly interesting information class and setting the degree of interest for the designated information class by the above operation is performed by the degree of interest input means 60. The designated information classification and data on the degree of interest in this information classification are transmitted to the access history management means 4. The access history management means 4 updates the degree of interest in the specified information class stored in the memory 4B based on the specified information class and data on the degree of interest in this information class.

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

  The access history reset unit 70 executes the following processing. When the user operates a predetermined key on the keyboard (for example, a key that clearly indicates “reset”) in the same manner as the interest level input unit 60, the access history reset unit 70 operates. The access history reset unit 70 outputs a command signal to the access history management unit 4 in the same manner as the interest degree input unit 60, based on the user identification information input from the keyboard. As a result, all information classifications for the corresponding user and data on the degree of interest in these information classifications are retrieved from the memory 4B, output to the monitor 8 by the editing means 7, and displayed. The user uses the mouse or the like to specify an information category whose interest level is to be reset among the information categories displayed on the monitor 8. The access history reset unit 70 sets the interest level of the information category whose interest level is to be reset to zero, and transmits this value to the access history management unit 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 degree of interest in the information classification and the access history information in the memory 4B can be reset, and the provision of information that the user has no interest in can be prevented.

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

  When there are a plurality of information belonging to an 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 the user selects an index of information that the user wants to use from the plurality of displayed indexes, the index is received from the interest index presenting means, and information corresponding to the index is selected from the information source 6. The information classification having a high degree of user interest is an information classification in which the user is interested.

  Specifically, at the time of the automatic mode, the access history management means 4 sorts one or a plurality of information categories in which the degree of interest of the user specified by the user identification information is higher than a certain level (for example, a plurality of information categories in which the user is interested). Is output to the interest information selecting means 5. When information belonging to one or a plurality of specified information classes is present in the information source 6, the interest information selection unit 5 stores the index of all the corresponding information in the access history management unit 4 for each information class. Will be sent back. The interest information selecting means 5 is means for extracting information belonging to the information class based on the information class (the class specified by the class designation data) in which the user is interested from the information source, and at least one information class. When there are a plurality of pieces of information to be taken out, a means for outputting each index corresponding to each piece of information is provided.

  Here, the index may be assigned to the information in advance, or the interest information selecting means 5 may assign the index. As an example of assignment by the interest information selecting 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. Just fine.

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

  The indexes are displayed on the monitor 8 in a form in which the degree of interest in the information classification to which the information corresponding to each index belongs is known. For example, as shown in FIG. 5, the indexes are arranged and displayed in descending order of the degree of interest, or a number indicating the degree of interest (for example, 1 for the highest, 2 for the second highest,...) The index is displayed at the top, or the index is changed in color 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. You. The information selection input means 2 outputs this information to the interest information index presenting means 9 and the editing means 7. The editing means 7 executes processing such as turning on the selected index according to this information.

  On the other hand, the interest information index presenting means 9 outputs the index selection information 13 specifying the selected index to the access history management means 4. The access history management means 4 outputs the index selection information to the interest information selection means 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 it as selection information 15 to the editing means 7. The editing means 7 outputs the information to the monitor 8. Further, the access history management means 4 updates the degree of interest in the information classification to which the information corresponding to the index belongs in the access history information of the user.

  If there is no selection operation from the user even after a certain time has elapsed after the index is displayed on the monitor 8, the access history management means 4 sends the index information to the interest information index presenting means 9 and the editing means 7. 14 is instructed to stop the output. As a result, the index displayed on the monitor 8 is deleted.

  However, if the user thereafter inputs the information to the information user identification determining means 1 for user identification, the index is output to the monitor 8 again according to the above-described processing. Also, when an index display instruction 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, which receives the instruction. The access history management means 4 may output the index information 20 to the editing means 7 again and display it on the monitor 8.

  As described above, if the interest information index presenting means 9 is used, when there are a plurality of information classifications having a high degree of interest of the user, and when there are a plurality of information corresponding to the information classifications, an index indicating an outline of these information is provided. Can be presented and the user can select it.

  By outputting the access history information 16 and the index information 14 to which the degree of interest is negatively added to an external device via the output unit 21, it is possible to externally determine what information each user is interested in. It becomes possible to grasp. For example, the information is stored in a portable floppy or a memory card via the output means 21 and read out by an external device, and the external device reads out the information individually for each user. You can grasp and analyze the information that has 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 is of interest to you by individual, so you can send ads for products related to information categories of high interest, It is possible to find an information category with a high number of users who have a high number of users, take measures such as selling products related to information parts with a high degree of interest and strengthening advertisements. It is also possible to apply the same to the field of mass media in the same way to actively provide interesting information. That is, it is possible to perform product sales and product advertisements that grasp market trends.

  For the detection of information classes with a large number of highly interested users, the degree of interest of each user is evaluated for each information class, and by searching for information classes with a large number of highly interested users, I can understand.

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

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

  The model access information storage means 10 stores model access information indicating a model of an 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 to obtain specialized knowledge in a specific field belongs, and is necessary to obtain general knowledge in various fields. Item information of the information classification to which the appropriate information belongs. The content is determined by the purpose for which the user wants to obtain the information.

  The template access information can be stored in a portable information medium such as a memory card, a ROM card, or a floppy disk, and provided to the information service system. Further, the template access information can be taken into the template access information storage means 10 using a communication system or the like.

  FIG. 6 shows a flow of operation when the template access information storage means 10 is used.

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

  On the other hand, the access history management unit 4 does not supply the information classification to the interest information selection unit 5 when the shortage information presentation is specified by the activation unit, and the user identification determination unit 1 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, of the access history information 16, the classification designation data having a high degree of interest is compared with the template access information. Then, based on the comparison result of the comparison means 11, the individual shortage information 12 is an information classification item having a low degree of interest in the access history information among the information classification items included in the template access information (the user is interested in the information classification item). The information classification item excluding the information classification having the information classification is retrieved, and this information classification item is output to the editing means 7 as insufficient information for the user (step 604).

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

  Here, the lacking information displayed on the monitor 8 is information indicating what kind of information classification is lacking for the user, and the user sees the displayed lacking information. In addition, it is possible to easily grasp information items and information fields that are lacking for oneself. Therefore, by obtaining the missing information thereafter, it becomes possible to obtain information of the information classification suitable for the model indicated by the model 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 unit 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 research terminal. 43.

  9 shows the appearance of the remote controller 30 shown in FIG.

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

  Now, the television 38 receives the output signal of the tuner 39 or the output signal of the recording device 41 according to the control signal of the tuner 39, the tuning means 36, or the tuning means in the television which inputs and selects the video signal of the antenna 37. Output means 40 for outputting one of the signals to the editing means 7A, 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 an output signal of the editing means 7A. Have.

  The remote controller 30 includes a program memory card 32, an OR input unit 44, a program information storage unit 33, a user-specific access information classification unit 34, an access history management unit 4A, a user identification determination unit 1A, a channel selection input unit 35, and interest information. Index presenting means 9A, channel selecting means 36, output means 21A, template access information storing means 10A, comparing means 11A, individual shortage information judging means 12A, activation means 22, classification sequence selecting means 63, interest degree input means 60, An access history reset unit 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 of the program memory card 32 is stored in the program information storage unit 33 via the OR input unit 44, all or for one week.

  Further, in the second embodiment, each broadcasting station broadcasts program information in addition to video information, and the television system transmits the program information received by the antenna 37 and the tuner 39 and the program information by the 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 broadcast program information is one week's worth of program information, each time information is received by the tuner 39, one week's worth of program information stored in the program information storage means 33 in the remote controller 30 is stored. Is updated via the OR input means 44. If each broadcast station transmits program information broadcasted 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 determining means 1A is a means for determining who is using the television. As shown in FIG. 8, the user is provided with a key group 800 assigned to each user on the remote controller 30, and the user is identified according to the key operation. However, each method of user identification as described in the first embodiment may be used.

  The channel selection input means 35 receives designation of a mode, which will be described later, and designation of channel selection. A program to be received by the tuning means 36 and the tuner 39, a program to be stored or reproduced by the video signal storage means, and a video signal to be output by the output means are selected. The classification sequence selection unit 63 receives designation of what classification the degree of interest is calculated and managed.

  User-specific access information classifying means 34, access history managing means 4A, user identification determining means 1A, interest information index presenting means 9A, output means 21A, template access information storing means 10A, comparing means 11A, individual shortage information determining The means 12A, the activating means 22, the interest input means 60 and the access history resetting means 70 have the same functions as the components of the same name in the information service system according to the first embodiment, so that the description is omitted.

  Hereinafter, the operation of the television system according to the second embodiment will be described.

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

  FIG. 9 shows a flow of the operation in this case.

  As shown in the figure, in this case, first, the user identification determining means 1A determines the user according to the key group 800 assigned to each user by the above-described method (the processing of step 301). The obtained user identification information for specifying the user is output to the user access information classifying means 34 (step 901). The tuning unit 35 receives the inputs of the three keys “auto” 801, “tuning” 802, and “manual” 803 of the remote controller 30 shown in FIG. 8, and sends the result to the user-specific access information classifying unit 34. Output (Step 902). The user-specific access information classifying means 34 determines whether the mode is designated in the automatic mode, the channel selection mode, or the manual mode based on the result taken from the information selection input means 35 (step 903).

  Here, the automatic mode is a mode in which the television system automatically selects a program desired by the user. Therefore, in the automatic mode, the user only needs to input information for identifying the user and information indicating that the mode is the automatic mode. Next, the channel selection mode is a mode in which the user directly selects a program. 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 a program corresponding to the selected station. The manual mode is a mode for simple channel selection by the user using the channel key 804. In this mode, channel selection is performed. However, the television system sets the selected program as an object of interest level learning. do not do.

  First, if the mode determined in step 903 is the channel selection mode, the user-specific access information classifying means 34 refers to the program information storage means 32, and the user identification determining means 1A Create class designation data for designating the class to which the program broadcast in the received station belongs, and output it 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 fetches information (user identification information and classification designation data) from the user-specific access information classification means 34, and temporarily stores the information in the memory 4b (step 905). The tuning means 36 selects the tuner 39 of the television 38 or the user 41A of the recording device 41 so as to select a program belonging to the classification specified by the classification designation data output from the user-specific access information classification means 34. 16) is controlled (step 906). Tuning by such a tuner is to extract information on the program specified by the classification designation data from a plurality of information transmitted from a plurality of broadcasting stations as information sources. In step 906, the tuning means 36 also controls the output means 40.

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

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

  The access history management unit 4A determines whether the result of the determination in step 908 is positive, that is, there is no input of another operation for a certain period after outputting information for channel selection to the channel selection unit 36, or the acknowledgment information 18A is output. If so, the degree of interest of the classification specified by the temporarily stored classification specification data in the access history information of the user specified by the user identification information is updated (step 909). Step 909 is a process of learning a classification of interest to the user based on the access information of the user, similarly to step 310 described above. Details of access history information, program classification, and learning of the degree of interest used in the second embodiment will be described later.

  If the result of the determination 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 user-specific access information classifying unit 34 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 class having the highest interest level, and outputs the determined class 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 classification, 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 case of the channel selection mode, the processing of step 907, step 908, and step 909 is performed, and the processing ends.

  On the other hand, if the mode determined in step 903 is the manual mode, the user-specific access information classifying means 34 outputs the selected contents to the selected means 36 (step 913), and the selected means 36 specifies the selected contents. The tuner 39 and the output means 40 are controlled so as to output the selected station to the editing means 7A (step 914), and the process ends.

  In the second embodiment, similarly to the first embodiment, when the automatic mode is designated, the program information storage means 32 is referred to, and when the time to start broadcasting a new program is reached. The degree of interest of the class to which the program belongs is compared with the degree of interest of the class to which the currently displayed program belongs. If the degree of interest to the class to which the program to be broadcast belongs is higher, the broadcast starts. May be switched to a 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 degree of interest of the classification to which the program belongs and the degree of interest of the currently displayed program are displayed. The degree of interest of the classes to which the program belongs is compared. If the degree of interest of the class to which the broadcast starts is higher, the program name or the like 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 received by the operation of, and the designation of the next candidate program is received, the channel selection may be switched to the program to start broadcasting and displayed on the monitor. In the case where the channel selecting means 36 selects a channel in the automatic mode, such as in these cases, if the program selection reason is always displayed on the monitor 8A by being superimposed on the video with a 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 class of the program, the degree of interest of the user with respect to the class of the program, and the like are passed from the access history management unit 4A to the editing unit 7A and are included in the program selection reason to be displayed.

  Further, the access history management means 4A refers to the program information storage means 33 and refers to the name of the currently broadcast program belonging to the same class as the selected program or the class of interest next to the class to which the selected program belongs. The name of the currently broadcasted program belonging to the classification or the like may be passed to the editing means 7A, and the editing means 7A may superimpose this on the video and display it as the next candidate, as shown in FIG. Then, when 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 displayed on the monitor. May be. The display and selection of the next candidate can be similarly performed in the first embodiment by using the above-mentioned index instead of the program name.

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

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

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

  FIG. 11 shows an example of access history information provided for each user.

  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 degree of interest 1102 of the user to each category 1100 is registered for each broadcast time zone 1101. That is, the use time zone is used as the use situation. In the use time zone, the observed use time zone is observed, and the user-specific access information classifying means 34 outputs the information by including it in the classification designation data, and the access history management means manages the degree of interest for each time zone. To Note that, in addition to the time zone, the day of use may be included in the classification designation data, and the management and processing of the degree of interest for each day of the week may be performed.

  Also, in this example, small genres such as English (education) and baseball (sports), which are provided for each large genre such as education and sports, are used as program classifications.

  However, these classification methods may be different for each user. That is, one classification is assigned to each program, the large genre is classified into one classification, for example, sports programs are classified into women's sports and men's sports, and ball games are classified into ball games and other sports. It may be. In this case, models of some classification examples are stored in advance in the user-specific access information classification unit 34, and each model is displayed on the monitor 8A via the access history management unit 36 and the editing unit 7A. Above, each user selects a model using the classification sequence selection key 806, and the classification sequence selection unit 63 registers the selected model in the user-specific access information classification unit 34 for the user. .

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

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

  Also in the second embodiment, similarly to the first embodiment, by increasing the interest level of the corresponding class in step 909, the frequency of access to the class is obtained, and this may be used as the interest level. Then, the access time is recorded in the access history information, and the number of accesses within a certain period in the past may be used as the degree of interest, or the obtained frequency is weighted in advance for each information classification, and The degree of interest may be used. In this case, the user-specific access information classifying means 34 displays the classification used by the user on the monitor 8A via the access history management means 36 and the editing means 7A. An 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 means 4A performs weighting using the weight registered for the frequency. Such a weight may be a weight that determines the priority of selection when a plurality of classifications having the same frequency exist.

  In addition, as described above, the access history management unit may be configured using a neural network so that the degree of interest is learned. Hereinafter, this case will be described.

  FIG. 14 shows the configuration of a neural network system provided in the access history management means 4A for storing and learning access history information. The configuration of FIG. 14 performs the process 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.

  The neural network itself is a generally known technology, as described in, for example, The MIT Press Parallel Distributed Processing, 1988, 7th edition, pp. 318 to 362, and will not be described in detail.

  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. , And 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 using the classification shown in FIG. 11 corresponds to the classification "English". , Output 4012 corresponds to the classification “French”.

  By the way, at the time of updating the degree of interest in the channel selection mode or the automatic mode (step 909), the access history management means 4A causes such neural network learning to be performed as follows. When the user identification information specifies the user A, the switching control unit selects the neural network 403A corresponding to the user A when the switching unit 402 or 403 selects the neural network 403A. If the determination result in step 908 is positive, that is, if there is no input of another operation for a certain period after outputting information for channel selection to the channel selection means 36, or if the acknowledgment information 18A has been output, or When a program is selected using an index to be described later, the learning control unit 405 refers to the program information storage unit 32 based on the signal 430, and the learning control unit 405 refers to the program information storage unit 32 and selects the input 4011 of the selected neural network 403A. To 401i, the value corresponding to the classification to which the currently broadcasted program belongs is set to the value 1, the others are set to the value 0, and among the outputs 4021 to 402i, the output values corresponding to the classification to which the selected program belongs. Is generated, and learning data in which other output values are 0 are created and stored. Then, the neural network is learned using the learning control signal together with the learning data created in the past. Thus, by giving an example of actual program selection to the neural network, the degree of interest in each category is learned. Specifically, the neural network determines the weight inside the neural network connecting the input and the output based on the input and output examples. The learning data used for the learning may be only the learning data created this time and the learning data for a certain period in the past from the present.

  Now, in the automatic mode, in the case of obtaining a classification having a high degree of interest of the user in step 912, or in the case of obtaining a classification having a high degree of interest of the user using an index described later, the access history management means 4A uses such a neural network. Let the network learn as follows. When the user identification information specifies the user A, the switching control unit selects the neural network 403A corresponding to the user A when the switching unit 402 or 403 selects the neural network 403A. Then, the access history management unit 4A refers to the program information storage unit 32, and sets the value of the input 4011 to 401i of the selected neural network 403A corresponding to the classification to which the currently broadcasted program belongs to a value of 1, Others are set to the value 0. Upon receiving this input, the neural network 403A outputs to the outputs 4021 to 402i the content that has already been learned, that is, a value corresponding to the determined internal weight. For example, a value corresponding to the learned degree of interest, such as a value 0.7 for an output corresponding to the class “English” being broadcast and a value 0.4 for an output corresponding to the class “French” being broadcast. Is output. In addition, a value 0 is output to an output corresponding to a classification that is not being broadcast.

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

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

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

  The operation in this case is substantially the same as the operation when 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 stores the program name of a program belonging to a category of high interest under the specified usage condition of the user and currently being broadcast, in the program information storage unit. 33, the degree of interest of the category to which the program belongs is added, and the result is output to the editing means 7A and the interest information index presenting means 9A as index information 14A with the degree of interest. The user's selection of a program using the displayed index is received by the channel selection input unit 35 by operating the candidate key 809 of the remote controller 30.

  In the television system according to the second embodiment, in place of the index, a program belonging to a category of high interest in the user under a specified use situation, May be displayed on the monitor 8A. In this case, n programs are sequentially selected from the programs belonging to the class having a higher degree of interest, and each sub-screen obtained by dividing the screen of the monitor 8A into n sub-screens belongs to the class having a higher degree of interest. The video of the program is displayed in order. Then, selection of a program is accepted on the display.

  By outputting the access history information 16 and the index information 14A to which the degree of interest has been added to the other remote controller via the output terminal 810 of the remote controller by the output means 21A, the program information that the individual is interested in can be transmitted to the other remote controller. It can be transplanted. Further, similarly to the information service system of the first embodiment, such information may be transmitted to the investigation terminal 43.

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

  FIG. 15 shows the operation of the television system in this case. As shown in the figure, the information service system according to the first embodiment except 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 that the information is a program. Since the operation is the same as that in the case where the template access information storage means 10 is used, the description is omitted.

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

  First, when a program with a high degree of user interest is stored in the recording device 41, the user presses the VTR 812, the recording 813, and the automatic 801 key of the remote controller 30, and further specifies the user with the user key 800. Information from these operations is input to the user identification determination means 1A and the channel selection input means 35. Thereafter, by the same operation as in FIG. 9, the program being broadcast, which belongs to the category of the highest interest of the user, is selected. Thereafter, as shown in FIG. The tuner 41A is supplied with a tuning signal 41C designating a station broadcasting the selected program, and a program having a high degree of user interest is selected. Then, the recording means 41B is controlled by the recording signal 41D to record the program. As a storage medium used in the recording means 41B, various information storage media such as a tape, a floppy disk, and an optical disk can be applied. After recording the program, the recording means 41B outputs an address 45 indicating which part of the storage medium stores the program to the channel selecting means. The channel selection means 36 stores the address, the recorded program, and the degree of interest of the classification to which the program belongs in association with each other.

  Next, when reproducing the recorded program, the user presses the keys of the VTR 812 and the reproduction 814 of the remote controller 30, and further specifies the user with the user key 800. When such an operation is received, the channel selection unit 36 outputs an address corresponding to the program corresponding to the highest degree of interest to the user among the recorded programs to the reproduction unit 41E as the reproduction signal 41F. . The reproducing means 41E creates information specified by the reproduction signal 41F among the information which is not recorded by the recording means 41B but is recorded and outputs the information to the output means 40. In addition, the channel selection unit 36 controls the output unit 40 to output the information signal reproduced by the reproduction unit 41E to the editing unit 7A. On the other hand, when receiving this signal, the storage means 41B reproduces the program from the received address and outputs it to the output means 40. As a result, the program of the highest interest among the recorded programs is reproduced for the user and displayed on the monitor 8A. Reproduction of the next candidate recorded program is accepted by inputting the candidate key 809 of the remote controller 30. Alternatively, the reproduction of the next candidate recorded program is automatically performed after the reproduction is completed.

  As described above, according to the television system according to the second embodiment, the user can record a program belonging to a category having a high degree of interest and record it at any time.

  Next, the investigation terminal 43 will be described.

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

  The access history storage unit 4A of the remote controller 30 outputs the classification of the program having a high degree of interest for each individual to the investigation terminal 43 via the output terminal by the output unit 21A. 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. The 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, to determine who is interested in what kind of program or Are used to determine what kind of programs are viewed as a whole as a whole.

  On the other hand, the audience rating survey storage means 54 is a means for storing what classification 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 tuned in what time zone as shown in FIG. Is stored. In any case, if one program is classified into one category, these pieces of information can be obtained for each program.

  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 according to the third embodiment includes an access history management unit 4A, an interest information index presenting unit 9A, a template access information storage unit 10A, a comparison unit 11A, an individual shortage information provided in the remote controller 30 shown in FIG.
