- the address of the electronic commerce site provided by the server device 200 is stored in the address storage unit 110 as the monitoring target address. If a corresponding HTTP request is detected, the process proceeds to step S17. If not detected, the process proceeds to step S20.
- the keyword extraction and transmission unit 160 prioritizes the keywords registered in the keyword information table 121 based on the type.
- the priority of the type may be specified by the user in advance, or may be determined from the execution frequency of various types of application software. For example, a type with higher execution frequency is set to a higher priority.
- the execution frequency can be determined from data registered in the keyword information table 121, or can be determined by separately monitoring the process of the client device 100.
- the keyword extraction / transmission unit 160 prioritizes keywords in the same type based on the date and time. For example, a keyword with a new date and time is set to a higher priority. Note that keywords that have passed a predetermined period (for example, one week) or more after registration may be excluded from transmission candidates. Further, keywords that have passed for a predetermined period or longer may be deleted from the keyword information table 121.
- steps S17 and S18 may be performed in reverse order to prioritize keywords by giving priority to the date and time. For example, prioritize by classifying the elapsed period from registration into multiple ranges (for example, less than 1 day, 1 day to less than 3 days, 3 days or more, etc.), and prioritize keywords belonging to the same category by type You can also.
- the keyword extraction and transmission unit 160 adds some or all of the keywords prioritized in steps S17 and S18 to the HTTP request detected in step S16. For example, a predetermined number (for example, five) of keywords are selected and added from the higher priority. At that time, priority information of each keyword can be added together.
- Step S20 The keyword extraction / transmission unit 160 determines whether the operation of the browser 130 has ended (whether the web browser process has ended). When the operation is finished, the monitoring of the browser 130 is finished. If the operation has not ended, the process proceeds to step S11.

Thereby, keywords that characterize the user's interest can be collected. Further, the client device 100 automatically transmits a part or all of the accumulated keywords when accessing the server device 200. Thereby, the server apparatus 200 can know a user's interest.
- the client device 100 may add a keyword to an HTTP request that specifies an arbitrary address in the electronic commerce site, or an HTTP request that specifies a specific address (for example, a route address) in the electronic commerce site. Only keywords may be added. Also, when accessing the same e-commerce site multiple times in succession, that is, when sending an HTTP request specifying the address in the e-commerce site multiple times in succession, a keyword is added only to the first HTTP request. May be.
- the extraction process in steps S11 to S15 and the transmission process in steps S16 to S19 may be performed in parallel by separate processes.
- the keyword extraction process can also be executed by the keyword extraction unit 170 in parallel with the processing by the keyword extraction transmission unit 160 described above. However, the keyword extraction process may be stopped while the transmission process of steps S16 to S19 is being executed or while the electronic commerce site to be transmitted is being accessed.
- FIG. 11 shows an example of keyword extraction.
- FIG. 11 shows (1) an extraction example when using a search site, (2) an extraction example when using an electronic commerce site, (3) an extraction example when viewing a television broadcast program, and (4) an extraction example when reproducing music data. Is shown. It is also possible to extract keywords by a method other than the method shown in FIG.
- the keyword extraction / transmission unit 160 acquires the search word “AAA”.
- the type “search site” and the keyword “AAA” are registered in the keyword information table 121.
- the keyword extraction and transmission unit 160 acquires the web page title “BBB1” and the keyword “BBB2” in the meta tag of the HTML data. Also, the description “BBB3” given to the product image is acquired. As a result, the type “shopping site” and the keywords “BBB1, BBB2, BBB3” are registered in the keyword information table 121.
- the keyword extraction unit 170 acquires a program title “CCC1” and a performer name “CCC2”. As a result, the type “TV program” and the keywords “CCC1, CCC2” are registered in the keyword information table 121.
- the keyword extraction unit 170 acquires the music title "DDD1" and the artist name "DDD2". As a result, the type “music” and the keywords “DDD1, DDD2” are registered in the keyword information table 121.
- the keyword extraction / transmission unit 160 and the keyword extraction unit 170 can also extract keywords from sentences and phrases.
- keywords can be extracted by performing morphological analysis or syntactic analysis on a sentence.
- general terms that do not characterize the user's interest may be set as NG words, and NG words may not be extracted.
- FIG. 12 is a flowchart showing the control of the server device. This process is executed in the server device 200 in response to an HTTP request from the client device 100. In the following, the process illustrated in FIG. 12 will be described in order of step number.

- the request reception unit 230 determines whether the HTTP request received in step S21 includes a predetermined address (for example, the root address of the electronic commerce site). This determination can be made based on, for example, a path name. If the predetermined address is included, the process proceeds to step S23. If not included, the process proceeds to step S26.
- a predetermined address for example, the root address of the electronic commerce site
- the request reception unit 230 extracts keywords from the HTTP request received in step S21. Then, the extracted keyword is passed to the search unit 240.
- the search unit 240 collates the keyword acquired from the request reception unit 230 with the related word in the product information table 211 stored in the product information storage unit 210, and selects a product that matches the acquired keyword. . You may narrow down the goods selected to a predetermined number or less.
- a method of selecting a product having a related word that completely or partially matches a keyword can be considered.
- a plurality of keywords When a plurality of keywords are acquired, it may be conditional on having related words corresponding to all keywords, or may be conditional on having related words corresponding to at least one keyword. Moreover, it is good also as conditions on the condition that the ratio which the corresponding related word exists exceeds a predetermined threshold value.
- priority When priority is given to a keyword, you may weight according to priority.
- Step S25 The search unit 240 acquires the product data selected in Step S24 from the product information storage unit 210. Also, an HTML template corresponding to the address included in the HTTP request is acquired from the template storage unit 220. Then, text data that is product data is embedded in an HTML template to generate HTML data, which is output to the request receiving unit 230. Thereafter, the process proceeds to step S27.
- the request reception unit 230 and the search unit 240 perform normal processing according to the address included in the HTTP request. For example, in the case of an address corresponding to a product category, the search unit 240 generates HTML data indicating a product category list and outputs it to the request receiving unit 230. On the other hand, in the case of an address corresponding to each product, HTML data indicating the details of the product is generated and output to the request receiving unit 230.
- the request reception unit 230 adds an HTTP header to the data acquired from the search unit 240 to generate an HTTP response, and transmits the HTTP response to the client apparatus 100.
- the server device 200 receives an HTTP request including a keyword from the client device 100
- the server device 200 searches for a product that matches the keyword.
- product data that matches the keyword is also transmitted to the client device 100.
- the server apparatus 200 can present the goods considered that a user's interest is high.
- FIG. 13 shows an example of a display screen.
- the display screen 131 is an example of a screen displayed on the display 11 after the browser 130 accesses the server device 200.
- the e-commerce site root address “http://www.shoppingsite.com/top.cgi” is specified and accessed, a web page including a product classification area and a recommended product area is displayed as shown in FIG. Is displayed.
