The registration information ID 401 is registration information identification information. The registered user 402 is identification information of the user who registered the registration information of the corresponding registration information ID 401. This user identification information is, for example, a user ID described later. The title 403 and contents 404 are the title and contents of the registration information. The title 403 and the content 404 include a character string.

  An example of the browsing log information table 133 will be described with reference to FIG.

  The browsing log information table 133 includes a browsing user 501, browsing information 502, and the like. The browsing user 501 and the browsing information 502 are associated with each other. The browsing information 502 is identification information of the registered information that has been browsed. The browsing user 501 is identification information of a user who has browsed the corresponding browsing information 502.

  An example of the keyword appearance frequency information table 134 will be described with reference to FIG.

  The keyword appearance frequency information table 134 includes a user 601, a keyword ID 602, a frequency 603, a date 604, and the like. The user 601, the keyword ID 602, the frequency 603, the date 604, and the like are associated with each other. The user 601 is user identification information. The keyword ID 602 is keyword identification information included in the registration information registered, weighted, searched, and the like by the corresponding user. The frequency 603 is the frequency of the corresponding keyword. This frequency is a numerical value, and every time the user performs an operation such as registration, weighting, or search described later on information including a corresponding keyword, a numerical value corresponding to the operation is added. The date and time 604 is the latest date and time when information including the corresponding keyword is registered, weighted, searched, and the like.

  An example of the operation frequency information table 135 will be described with reference to FIG.

  The operation frequency information table 135 includes operations 701, weights 702, and the like. The operation 701, the weight 702, and the like are associated with each other. The operation 701 is an operation performed by the user, and in this embodiment, is any one of registration, weighting, and search. The weight 702 is a numerical value to be added when the keyword is included in the registration information for which the corresponding operation has been performed.

  Here, in general, when a user searches for registration information by specifying a search condition, the searched information is considered to be of interest to the user, so in this embodiment, it is added when searched. The frequency to do is the largest. The weighting operation is performed by the user on the registered information according to an operation example described later. For example, it is considered that the weighting operation is performed based on an assumption that the information may be remembered for the time being. Therefore, in this embodiment, the frequency to be added when weighted is minimized.

  As described above, the user terminal 2 is a communication terminal such as a PC having a browser (not shown), for example. Since such a communication terminal is the same as the prior art, details are omitted.

  Next, an operation example will be described.

  When using the information providing system of the present embodiment, the user inputs a user ID, a password, and the like by using an input device (not shown) of the user terminal 2 to give a login instruction. The user terminal 2 transmits the input user ID, password, etc. to the server device 1 together with an authentication request.

  An example of the operation of the server device 1 when an authentication request is received will be described with reference to FIG.

  In FIG. 8, when the related information providing unit 111 of the server device 1 receives the authentication request, the related information providing unit 111 performs an authentication process (S801). Specifically, for example, the related information providing unit 111 determines the combination of the user ID and password transmitted together with the user ID and password in the authentication table (not shown) stored in the secondary storage device 13. It is determined whether or not the combination matches. If the result of this determination is that they do not match, the related information providing unit 111 transmits information notifying that an authentication error has occurred to the user terminal 2 and ends the processing. If the result of the determination is that they match, the related information providing unit 111 starts providing information to the user terminal 2 that has transmitted the authentication request including the user ID and password. The server device 1 stores the authenticated user ID and the connection identification information obtained by the authentication process in association with the memory 12 and the like, and includes the connection identification information in subsequent communication with the user terminal 2. Each user is identified by transmitting and receiving data. Such authentication processing and communication management processing are the same as in the prior art.

  Next, the related information providing unit 111 selects one or more keywords that are included in the registered information of registered, weighted, and searched authenticated users (S802). Specifically, the related information providing unit 111 sorts the keyword appearance frequency information table 134 in descending order based on the frequency 603 associated with the user 601 that matches the user ID transmitted together with the authentication request. Next, the related information provision part 111 selects the keyword 602 matched with the user 601 matched with the user ID transmitted with the authentication request from the sorted keyword appearance frequency information table 134 in descending order. Here, the keyword 602 to be selected may be one or plural. When a plurality of keywords 601 are selected, a predetermined number may be selected in descending order, or some or all of the corresponding frequencies 603 may be selected from a predetermined threshold or more.

  The related information providing unit 111 includes the keyword selected in S802 described above from the registration information table 132, and is not registered information registered by the user authenticated in S801 described above and the user authenticated in S801 described above is past. Registration information that has not been browsed is selected (S803). For this purpose, for example, the related information providing unit 111 reads the keyword 302 corresponding to the keyword ID 301 that matches the keyword ID selected in the above-described processing of S802 from the keyword information table 131. Next, the related information providing unit 111 refers to the registered user 402, title 403, content 404, and the like of each row in the registration information table 132, includes the read keyword 302, and authenticates the user ID in S801 described above. A row that is not a registered user 402 that matches is selected. The related information providing unit 111 includes the combination of the registration information ID 401 of the selected row and the user ID of the user authenticated in S801 described above in the corresponding browsing user 501 and browsing information 502 in the browsing log information table 133. Judge whether it is. As a result of this determination, if the corresponding information is not included in the browsing log information table 133, the registration information of the selected row is registered by the user who includes the keyword selected in the above-described S802 and is authenticated in the above-described S801. Registration information that has not been browsed by the authenticated user in the past.

  At this time, when there are a plurality of corresponding registration information, the related information providing unit 111 may select only some of them or all of them. Further, when there are a plurality of corresponding registration information, the related information providing unit 111 may select the registration information from the order including the most keywords selected in S802 described above.

  The related information providing unit 111 transmits to the user terminal 2 data for instructing registration, search, browsing, and the like described later. This data includes the registration information selected in the process of S803 described above. If the corresponding registration information is not selected in the above-described processing of S803, the registration information may not be included (S804).

  The user terminal 2 outputs a screen based on this screen data to a display (not shown) or the like. FIG. 9 shows a screen example. In FIG. 9, a screen 901 includes an area 911, a button 921, and the like. An area 911 is an area for displaying the registration information selected in the process of S803 described above. A button 921 is used to instruct registration, search, browsing, and the like, which will be described later. In the example of FIG. 9, the screen 901 shows an example in the case where there is no corresponding registration information in the above-described processing of S803. In this case, registration information is not displayed in the area 911. The user instructs registration, search, browsing, or the like by pressing any button 921 using the input device of the user terminal 2.

  First, an operation example when the user instructs registration will be described with reference to FIG.

  The user uses the input device to instruct the start of registration processing by pressing a button 921 for instructing the start of registration in the screen 901 described above. The user terminal 2 transmits a registration start request to the server device 1. The registration processing unit 112 of the server device 1 transmits screen data for receiving registration information to the user terminal 2. The user terminal 2 outputs the received screen data to a display or the like. An example of the output screen is shown in FIG. In FIG. 11, a screen 1101 has an area 1111, an area 1112, and the like. An area 1111 is an area for inputting a title of information to be registered. An area 1112 is an area for inputting contents of information to be registered. The user inputs information to be registered in the area 1111 and the area 1112 using the input device, and instructs registration. The user terminal 2 uses the information input in the area 1111 and the area 1112 as the title and contents, and transmits them to the server apparatus 1 in a registration request.

  In FIG. 10, when the registration processing unit 112 of the server apparatus 1 receives the registration request (S1001), the information included in the registration request is stored in the registration information table 132 or the like (S1002). Specifically, for example, when receiving a registration request, the registration processing unit 112 issues a registration information ID. Further, the registration processing unit 112 stores the issued registration information ID, the user ID of the user who requested registration, the title, the content, and the like as the registration information ID 401, the registered user 402, the title 403, the content 404, etc. of the registration information table 132. To do.

  Next, the word extraction unit 115 extracts a word from information newly stored as registration information (S1003). Specifically, for example, the word extraction unit 115 extracts nouns, verbs, and the like from the character strings such as the title 403 and the contents 404 stored in the above-described S1002 in the registration information table 132. The word extraction process of the word extraction unit 115 is the same as that of the prior art, but may be realized by, for example, a morphological analysis program.

  The keyword extraction unit 116 searches for words that are not included in the keyword information table 131 among the words extracted by the word extraction unit 115, and stores them as new keywords in the keyword information table 131 (S1004). For this purpose, the keyword extraction unit 116 compares each word extracted by the word extraction unit 115 with each of the keywords 302 in the keyword information table 131. If there is something that does not match by this comparison, the keyword extraction unit 116 sets the word as a new keyword. The keyword extraction unit 116 issues a keyword ID, and stores the issued keyword and a new keyword as the keyword ID 301 and the keyword 302 in the keyword information table 131.

  The frequency addition unit 117 updates the frequency, appearance date and time of the word (keyword) extracted in S1003 described above in the keyword appearance frequency information table 134 (S1005). Specifically, for example, the frequency adding unit 117 reads the weight 702 “2” corresponding to the operation 701 “registration” from the operation frequency information table 135. The frequency adding unit 117 searches the keyword information table 131 for the keyword 302 that matches each word extracted in S1003 described above, and extracts each keyword ID 301 corresponding to each corresponding keyword 302. Next, the frequency adding unit 117 searches for the user ID and the keyword 602 in each row of the keyword appearance frequency information table 134 that match the user ID of the user who requested registration and the keyword ID extracted by the above processing. . When there is a corresponding user 601 and keyword 602, the frequency adding unit 117 adds the weight 702 “2” read out in the above process to the corresponding frequency 603. Further, the frequency adding unit 117 updates the corresponding date and time 604 to the current date and time acquired by an internal clock (not shown) or the like. When there is no corresponding user 601 and keyword 602, the frequency adding unit 117 newly stores a user ID and a keyword ID in the user 601 and keyword 602 in the keyword appearance frequency information table 134. Further, the frequency adding unit 117 stores the weight 702 “2” read out in the above process and the current date and time acquired by the internal clock in the corresponding frequency 603 and date and time 604.

  Next, an operation example when the user instructs registration information search will be described with reference to FIG.

  The user uses the input device to instruct the start of the search process by pressing a button 921 for instructing the search on the screen 901 described above. The user terminal 2 transmits a search start request to the server device 1.

  The registration information search processing unit 113 of the server device 1 transmits screen data for receiving search conditions to the user terminal 2. The user terminal 2 outputs the received screen data to a display or the like. An example of the output screen is shown in FIG. In FIG. 13, a screen 1301 has a region 1311 and the like. An area 1311 is an area for inputting a search condition. Using the input device, the user inputs a character string considered to be included in the registration information to be searched for in the area 1311 and instructs the search. The user terminal 2 transmits a search request including the character string input in the area 1311 as a search condition to the server device 1.

  In FIG. 12, when the registration information search processing unit 113 of the server device 1 receives the search request (S1201), it extracts a character string that is a search condition from the search request, The registration information to be included is searched (S1202). Therefore, for example, the registration information search processing unit 113 determines whether or not the character strings of the titles 403 and the contents 404 of the registration information table 132 match those extracted from the search request. If a match is included, the registration information search processing unit 113 reads the title 403 and the content 404 together with the corresponding registration information ID 401.

  Next, the word extraction unit 115 extracts a word from a character string that is a search condition (S1203). Since this specific example is the same as S1003 described above, a description thereof will be omitted. Next, the keyword extraction unit 116 searches for words that are not included in the keyword information table 131 among the words extracted by the word extraction unit 115, and stores them as new keywords in the keyword information table 131 (S1204). Since this specific example is the same as S1004 described above, a description thereof will be omitted.

  The frequency adding unit 117 updates the frequency, appearance date, and the like of the word (keyword) extracted in S1203 described above in the keyword appearance frequency information table 134 (S1205). Specifically, for example, the frequency adding unit 117 reads the weight 702 “3” corresponding to the operation 701 “search” from the operation frequency information table 135. The frequency adding unit 117 searches the keyword information table 131 for the keyword 302 that matches each word extracted in S1203 described above, and extracts each keyword ID 301 corresponding to each corresponding keyword 302. Next, the frequency adding unit 117 searches the corresponding user 601 and keyword 602 in the keyword appearance frequency information table 134 for a match with the user ID of the user who requested the search and each keyword ID extracted by the above processing. To do. When there is a corresponding user 601 and keyword 602, the frequency adding unit 117 adds the weight 702 “3” read out in the above process to the corresponding frequency 603. Further, the frequency adding unit 117 updates the corresponding date and time 604 with the current date and time acquired by an internal clock or the like. When there is no corresponding user 601 and keyword 602, the frequency adding unit 117 newly stores a user ID and a keyword ID in the user 601 and keyword 602 in the keyword appearance frequency information table 134. Further, the frequency adding unit 117 stores the weight 702 “3” read out in the above process and the current date and time acquired by the internal clock in the corresponding frequency 603 and date and time 604.

  The registration information search processing unit 113 transmits the registration information searched in the process of S1202 described above to the user terminal 2 (S1206). Specifically, for example, the registration information search processing unit 113 transmits at least a part of the read character strings of the title 403 and the content 404 to the user terminal 2 together with the corresponding registration information ID 401.

  The user terminal 2 outputs the received registration information to a display or the like. An example of the output screen is shown in FIG. In FIG. 14, a screen 1401 is an example of displaying a list of registration information retrieved by the processing of the server device 1 described above.

  Next, an example of operation when browsing and weighting registered information will be described with reference to FIG.

  Here, browsing of registration information includes browsing the registration information searched in the above-described search process using character strings, and browsing the registration information searched under other arbitrary search conditions. To do. In either case, the operation example of the server device 1 is the same as the other operation examples except for the registration information that is actually transmitted to the user terminal 2.

  When browsing the registration information searched in the search process using the character string described above, the user designates the registration information desired to be browsed among the registration information on the screen 1401 using the input device, and instructs a browsing request. To do. The user terminal 2 transmits a browsing request including the registration information ID of the designated registration information to the server device 1.

  When browsing registered information searched under other arbitrary search conditions, the user starts browsing by pressing a button 921 for instructing to start browsing in the above-described screen 901 using, for example, an input device. Instruct. The user terminal 2 transmits a browsing request to the server device 1.

  In FIG. 15, the browsing process part 114 of the server apparatus 1 transmits registration information to the user terminal 2 (S1501). Here, when browsing the registration information searched in the search process by the above-mentioned character string, the browsing request containing registration information ID is transmitted from the user terminal 2 as mentioned above. The browsing processing unit 114 of the server apparatus 1 reads out the title 403, the content 404, and the like corresponding to the registration information ID 401 that matches the registration information ID extracted from the browsing request from the registration information table 132, and the read title 403, the content 404, etc. Is transmitted to the user terminal 2. Moreover, when browsing the registration information searched by arbitrary search conditions, the browsing request | requirement is transmitted from the user terminal 2 as mentioned above. The browsing processing unit 114 of the server device 1 reads the registration information ID 401, title 403, content 404, and the like from the registration information table 132, and transmits the read registration information ID 401, title 403, content 404, and the like to the user terminal 2. In this case, the registration information to be read out may be arbitrary, for example, the registration information with the latest registration date, registration information registered by a user such as the same department as this user, registration information randomly selected by the server device 1 or the like. is there.

  Next, the browsing processing unit 114 updates the browsing log information table 133 (S1502). Specifically, for example, the browsing processing unit 114 uses the user ID of the user who has requested browsing, the registration information ID of the registration information transmitted in the process of S1501 described above, the browsing user 501 of the browsing log information table 133, and the browsing information. Further stored as 502 or the like.

  On the other hand, the user terminal 2 that has received the registration information from the server device 1 outputs the received registration information to the output device. An example of the screen output on the display is shown in FIG. In FIG. 16, a screen 1601 is an example in which the title 403, contents 404, and the like transmitted by the server apparatus 1 are displayed. When the user browses the displayed registration information and is interested in the registration information, the user presses the button 1611 using the input device of the user terminal 2. When the button 1611 is pressed or the like, the user terminal 2 transmits a weighting request including the registration information ID of the registration information required to be displayed to the server device 1.

  The browsing processing unit 114 determines whether or not to receive a weighting request (S1503).

  As a result of the determination in S1503, when the weighting request is not received and the end instruction or the like is received, the browsing processing unit 114 ends the process.

  As a result of the determination in S1503, when a weighting request is received, the word extraction unit 115 extracts a word from the registration information transmitted to the user terminal 2 in the process of S1501 described above (S1504). Since this specific example is the same as S1003 and S1203 described above, a description thereof will be omitted. Next, the keyword extraction unit 116 searches for words that are not included in the keyword information table 131 among the words extracted by the word extraction unit 115, and stores them as new keywords in the keyword information table 131 (S1505). Since this specific example is the same as S1004 and S1204 described above, a description thereof will be omitted.

  The frequency adding unit 117 updates the frequency, appearance date and time of the word (keyword) extracted in S1504 described above in the keyword appearance frequency information table 134 (S1506). Specifically, for example, the frequency adding unit 117 reads the weight 702 “1” corresponding to the operation 701 “weight” from the operation frequency information table 135. The frequency adding unit 117 searches the keyword information table 131 for the keyword 302 that matches each word extracted in S1504 described above, and extracts each keyword ID 301 corresponding to each corresponding keyword 302. Next, the frequency addition unit 117 searches the corresponding keyword 601 and keyword 602 in the keyword appearance frequency information table 134 to match the user ID of the user who requested weighting and the keyword ID extracted by the above processing. To do. When there is a corresponding user 601 and keyword 602, the registered information search processing unit 113 adds the weight 702 “1” read out in the above process to the corresponding frequency 603. Further, the frequency adding unit 117 updates the corresponding date and time 604 with the current date and time acquired by an internal clock or the like. When there is no corresponding user 601 and keyword 602, the frequency adding unit 117 newly stores a user ID and a keyword ID in the user 601 and keyword 602 in the keyword appearance frequency information table 134. Further, the frequency adding unit 117 stores the weight 702 “1” read out in the above process and the current date and time acquired by the internal clock in the corresponding frequency 603 and date and time 604.

  As described above, in this embodiment, the frequency is not added to the registered information simply browsed, but the frequency is added only when the user intentionally instructs weighting. This makes it possible to accurately provide information that the user is interested in even when the user browses by mistake or when the user browses the information that is not of interest.

  When a user who has logged off after performing registration, weighting, search, and the like as described above logs in again, the server apparatus 1 determines that the user is interested by performing the same processing as in FIG. Search registered information. The user terminal 2 outputs the received information to the output device. FIG. 17 shows a screen example output from the user terminal 2 to the display. In the example of FIG. 9 described above, registration information is not particularly displayed in the area 911. However, after the user performs the above-described registration, weighting, search, and other processes, registration information is displayed in the area 1711 as shown in a screen 1701 in FIG.

  As described above, in the information providing system of the present embodiment, when a user logs in to the information providing system, registration information determined to be interested in the user is displayed. Therefore, even if the user does not consciously search for information or the like, it is possible to provide registration information that is determined that the user is interested.

  Moreover, the weighting with respect to those information differs for every process performed with respect to the information handled on an information provision system, such as registration, weighting, and search of information. Thereby, it is possible to optimally count up the frequency for determining that the user is interested.

  Further, since the information registered by itself and the information browsed in the past are not provided, it is possible to avoid providing duplicate registration information.
