In the above-described search system according to the first and second aspects of the present invention, the price-containing page search means extracts only pages including a price character string in which an integer is arranged before or after a currency symbol. It is preferable to be configured.
In addition, when a page on the web is created in XML, it is preferable that the price-containing page search means is configured to extract only a page including a definition tag representing a price.
Further, the search system further includes a purchase intention page deletion unit that deletes a page including a term indicating purchase intention from the page acquired by the price-containing page search unit, and the index search unit includes the purchase intention page deletion unit. It is preferable that a product name or a service name and a price are extracted as an index from a page that has not been deleted.

And a keyword search means comprising means for separating the extracted product sales page into an e-commerce page and an auction page by keyword search, and the index search means extracts the index only from the product sales page. It is preferable to be configured.

The present invention is configured as described above, searches a page with a keyword specializing in a price universally used in the world, creates a database, and indexes product names, service names and prices on the page. Therefore, the load on the server is drastically reduced as compared with the conventional example. Further, the load on the robot itself is small, and the time required to find a new page or an updated page is significantly shortened as compared with the conventional example.
Furthermore, since only the product / service sales page and auction page can be provided to the user, it is possible to provide an appropriate search result in accordance with the user's intention to purchase the product / service.

  The product / service search system on the web according to the present invention provides a product / service corresponding to the content provided by the website if there is a character string with an integer before or after the currency symbol of each country. It was developed focusing on the fact that there is. That is, if the content on the web page contains a character string with integers before and after the currency symbol, such a character string represents the price, so the web page providing the page is displayed. This is because the possibility that the site is an e-commerce mall or an auction mall is extremely high.

Then, the present invention searches for a web page including such price character strings (continuous currency symbols and integers), searches for a product / service name corresponding to the price from the page, and searches for the product / service name and its price. Are provided in a state where the user can easily search, together with the URL of the page to which the link to each page is attached.
In the following description, “product” and “service” provided for a fee will be referred to as “product”. A character string accompanied by an integer before or after a currency symbol is referred to as a “price character string”.

  FIG. 1 shows a basic configuration of a product / service search system on the web (hereinafter simply referred to as “search system”) according to the present invention. In FIG. 1, 10 is a search service site that provides a search system, and 20 is the Internet. The search service site 10 includes a robot 1, a web information database (DB) 2, a price character string search engine 3, a price character string containing page DB 4, a keyword search engine 5, a product sales page DB 6, an index search engine 7, an index DB 8, and a user. A search service engine 9 is provided.

In the search system shown in FIG. 1, the robot 1 searches the Internet 20, swims, and searches for new pages and updated pages on the Internet 20. The source code of the entire page obtained by the robot search is stored in the web information DB 2. Of course, when the search system is started up, all pages on the web become new pages, and the source code of the page obtained by the search of the robot 1 is stored in the page information DB 2 according to the search.
Then, the price character string search engine 3 searches the source code of the page newly stored or updated in the web information DB 2 and extracts the source code of only the page including the price character string. The source code of the extracted page is stored in the price character string containing page DB4. For example, in the page of the source code as shown in FIG. 2, “¥ 6,930” is searched as a price character string, so the source code of this page is stored in the price character string containing page DB4.
The robot 1 may be provided with a price character string search function. In this case, the web information DB 2 is not necessary.

  Next, the keyword search engine 5 searches the source code of the page stored in the price character string-containing page DB 4 using a keyword for a full-text search, thereby indicating a purchase intention page (for example, a reverse auction). Page). As a keyword for that purpose, for example, terms indicating the intention of purchasing a product such as “Want”, “Want”, and “Ikaga” are used, and a page including any of these terms is searched. The source code of the purchase intention page extracted by such keyword search is deleted, and the source codes of the remaining pages are stored in the product sales page DB 6. As a result, most of the pages stored in the product sales page DB 6 are directly related to e-commerce and auction.

  The keyword search engine 5 further identifies whether the page stored in the product sales page DB 6 is for e-commerce or auction. For this identification, it is determined whether or not a keyword associated with an auction such as “current price” is included in the page, or whether “auction” or “auctions” is included in the URL. If is affirmative, it is determined to be an auction page. And the mark which shows that a sales form is an auction is attached to the applicable page stored in merchandise sales page DB6. Pages that are not marked are for e-commerce.

Whether the source code of the purchase intention page is stored in a database separate from the e-commerce and auction pages, and the contents of the e-commerce and auction pages match the contents of the purchase will page It may be configured to determine whether there is a matching page and notify the provider of both pages when there is a matching page.
In addition, the product sales page DB6 may not be specially provided, and a flag may be added corresponding to the page in the price character string containing page DB4 to indicate the product sales page.

The index search engine 7 analyzes the source code of the e-commerce and auction pages extracted and stored in the product sales page DB 6 in this way, and corresponds to “product name” and “amount” from each page. Information is extracted, and these information and the URL of the page are stored in the index DB 8 as index information. The index DB 8 also stores a sales form as to whether it is for auction or e-commerce.
For example, in the example of FIG. 2, the index information is as follows.
Product Name: Orange Keyboard Amount: ¥ 6930
URL: http://store.orange.com
Sales form: E-commerce

  In this way, the search system of the present invention searches for a page that includes a “price character string” and does not include a “product purchase intention term”, and presumes that the page is for E-commerce or auction. Then, the index DB 8 is constructed by extracting the URL of the page, the product name, and the amount of money as an index.

  The user search service engine 9 has a function of providing index information stored in the index DB 8 on the web in a form that is easy for a user to search. Therefore, for example, a user search input page as shown in FIG. 3A is provided to the user on the web. In the user search input page, for example, input fields for “product name”, “amount”, “sales method”, and “payment method” are provided. The “Sales method” input field is for inputting a sales form, which is E-commerce or auction.

  When the user inputs a predetermined search key / query on the user search input page, the user search service engine 9 searches the index DB 8 according to the search algorithm, and the search result is displayed in the designated display method for these search keys / queries. Is displayed. For example, when the user inputs “Orange Keyboard” in the product name column and “¥ 6800” to “¥ 7300” in the amount column, the user search service engine 9 matches the input conditions. Information to be searched is retrieved from the index DB 8, and a product information display page as shown in FIG. 3B is provided. In the example of FIG. 3B, orange keyboard dealers are listed in order from the lowest price. If the amount is not entered on the user search input page, the merchandise information page will show all the stores selling the entered product name “Orange Keyboard” along with the product price in the appropriate order. Is displayed. The corresponding URL may also be displayed.

Note that “sales method” and “payment method” in the user search input page of FIG. 3A are in a form in which one is appropriately selected from the pull-down menu. As a pull-down menu, the sales method includes a normal sales method and an auction, and the payment method includes credit card payment, merchandise exchange, transfer, and the like.
It is not always necessary to provide input fields for “sales method” and “payment method”. Even when these input fields are provided, the search result is displayed on the product information display page without any user input in these input fields.

  Each store and price group on the product information display page has a link to the URL of the store. For example, when the user selects the lowest price orange house group, The session switches to the orange keyboard sales page. As a result, the user can obtain detailed information on the orange keyboard on the sales page and, when the purchase is decided, can perform the purchase procedure on the web page.

  Note that only the product sales page is extracted and used by the price character string search engine 3 and the keyword search engine 5, but even with these search engines, pages other than the product sales page may be included in the extracted page. Although it is considered that such a possibility is very low, when it becomes clear that the page is a non-commodity sales page, the index information corresponding to the page may be appropriately deleted from the index DB 8.

In the above example, the robot swims around the web to acquire the source code of the page on the web, and the price string search engine extracts the page containing the price string from the example, and the robot The example in which the robot acquires only the page including the price character string by providing the price character string search function has been described.
In these examples, if a page on the web is generated in XML, the page includes a definition tag <retail indicating the price. Since price> is included, the function of the price string search engine in the former example and the price string search function of the robot in the latter example are replaced with a function of detecting a page including a price definition tag.

It is a block diagram showing the structure of the search system which concerns on this invention. It is explanatory drawing for demonstrating operation | movement of the search system which concerns on this invention. It is explanatory drawing which illustrates the user search input page and search result display page which the search system which concerns on this invention provides.
