(2. Information collection process)
Next, the processing operation of the system shown in FIG. 1 will be described. The processing of this system is broadly divided into two types: information collection processing and number presentation processing. Here, the information collection process will be described first. FIG. 2 is a flowchart showing an overview of information collection processing in the system shown in FIG. First, when the processing terminal 300 is accessed from the user terminal 100, the processing server 300 recognizes the accessing user. In the present embodiment, the user terminal 100 is requested to input a user ID. Note that user recognition is not limited to authentication by inputting a user ID, and any method may be used as long as the user can be specified such as using cookie information of a browser. .

  When the processing server 300 presents the content after the user is recognized, the history collection unit 340 collects the presented content as a browsing history browsed by the user (S1). Then, the interested keyword generation means 350 determines whether or not the collected content includes a character string such as a sentence. If the character string is included, morphological analysis is performed (S2). Then, as a result of the morphological analysis, a character string determined to be appropriate from the extracted character string is generated as an interest keyword (S3). This is performed, for example, by determining that a character string included in a sentence in a predetermined number or more is appropriate as an interest keyword. On the other hand, when the search keyword is directly specified from the user terminal 100, the interested keyword generating unit 350 sets the specified keyword as it is as the interested keyword. Furthermore, the interest keyword generation means 350 registers the set interest keyword in the interest keyword storage means 360 in association with the user ID (S4). By performing such processing for each user, an interest keyword suitable for each user is accumulated in the interest keyword storage unit 360.

(3. Number presentation process)
Next, the number presentation process will be described. FIG. 3 is a flowchart showing an outline of the number presentation process in the system shown in FIG. First, when the processing terminal 300 is accessed from the user terminal 100, the processing server 300 requests the user terminal 100 that is the access source to input a user ID. When the processing server 300 receives the user ID, the interested keyword extracting unit 370 searches the interested keyword storage unit 360 with the user ID and extracts a corresponding interested keyword (S11). In this case as well, instead of inputting the user ID, the user may be specified using cookie information of the browser or the like.

  Subsequently, the content number presentation means 380 receives the interest keyword from the interest keyword extraction means 370, and searches the content storage means 310 with this interest keyword (S12). When the interesting keyword extracting means 370 extracts a plurality of interesting keywords from the interesting keyword storage means 360, the content is searched using all the extracted interesting keywords. When the search is performed for each interest keyword, the content number presentation unit 380 counts the corresponding number for each interest keyword, generates predetermined screen data, and presents it to the user terminal 100 (S13). Specifically, the screen data generated by the content number presentation unit 380 is passed to the network interface 320, and the network interface 320 transmits the data to the access source user terminal 100 via the network 200, and the user terminal 100 receives the screen data. The number of cases is presented by displaying the screen data on the screen.

  Here, the state of the screen of the user terminal 100 when the number of cases is presented is shown in FIG. As shown in FIG. 4, the number of cases is presented in a table format. In the example of FIG. 4, “IC card”, “security”, and “mobile phone” are set as keywords of interest, and the corresponding numbers are “22”, “ 17 ”and“ 32 ”. Further, in this system, classification can be given to the content stored in the content storage unit 310. In the example of FIG. 4, the case where it classify | categorizes into three of classification | category A, B, and C is shown, and the number of cases applicable to both a classification | category and an interest keyword is shown. In addition, although the number of each case shown in FIG. 4 is underlined, a URL link is set in this part. Therefore, when the user clicks the underlined number, the information specified by the set URL is accessed, and the title of the corresponding content is displayed in a list. Can be viewed.

  As shown in FIG. 4, the number of hits for each interest keyword is displayed in a list, and this interest keyword is directly specified in the past or set by analyzing the contents browsed in the past. Therefore, it is suitable for the content that I am interested in. That is, the user can instantly know how much content meets his / her preference by associating it with the search keyword simply by accessing the processing server 30.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made. For example, in the above-described embodiment, the processing server 300 is accessed from the user terminal 100 via the network, and processing is performed on the processing server 300 side.
