Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a document output technique for outputting a document such as a web (Web) page based on a request from a user. In particular, the web page is included in a search engine that automatically generates a web page index by a traveling robot. It is intended to be registered effectively.
[0002]
[Prior art]
In recent years, search engines have been provided on the Internet. When purchasing a product on the Internet, a search is often performed using such a search engine. Therefore, when electronic commerce or the like is performed using a web server, it is preferable that a web page of a site such as electronic commerce is registered in an index of a search engine. In a search engine, it is widely performed to collect index information for the search engine from a website using a patrol robot. It is desired that the web page of the site is effectively extracted as index information by such a traveling robot. Further, in such a search engine, a rank (score) is given to the web page of the search result from various viewpoints, and the search result is output in the rank order. Therefore, it is desirable to build a website to get a better rank.
[0003]
By the way, in electronic commerce and the like, a two-tier or three-tier system is often constructed by combining a web server and a database management server. In this case, the web page is dynamically generated using the CGI program of the web server or the program of the application server. That is, a path name and an argument (also referred to as a query character string, preceded by an argument delimiter “?” (Question mark)) are described in the URL included in the HTTP request. Then, the database management server performs database search, acquires predetermined information, and dynamically generates a desired web page based on this information. By using a dynamic page in this way, it is possible to immediately adapt to various electronic commerce environments such as a product master.
[0004]
However, when the patrol robot of the search engine patrols a site having an argument delimiter “?” In the URL, the total number of page acquisitions of the site is limited to 100, 1000, and the like. This is because such a site is dynamically processed by CGI, and it cannot be determined how many pages are on the website. For this reason, all pages cannot be included in the index information in a site that dynamically generates web pages.
[0005]
[Problems to be solved by the invention]
The present invention has been made in consideration of the above circumstances, and is intended to allow a traveling robot to perform index information acquisition processing for a larger number of web pages even when dynamically creating web pages and the like. It is aimed.
[0006]
[Means for Solving the Problems]
According to this invention, in order to achieve the above-mentioned object, the configuration as described in the claims is adopted.
[0007]
Here, the description of the scope of claims will be supplementarily described.
[0008]
Generally, a robot-type search engine periodically visits and fetches each page of a linked website. The captured pages are indexed with search keywords. At this time, evaluation is performed to determine the order in which web pages are displayed in search results. Although this evaluation differs depending on the search engine, it is performed based on the appearance frequency of the search keyword, the number of linked pages, the correct structural HTML description, the page size, and the like.
[0009]
In the present invention, in order to reflect all pages in the index information, the URL is rewritten so that the URL “?” Is not included. At this time, the search engine increases the evaluation of the page by increasing the number of mutual links (linked links) by adopting a configuration in which the mutual pages are linked, that is, a site map, a category index, an access ranking, and the like.
[0010]
It is also preferable to appropriately adjust the appearance frequency of the keywords used in the web page and the keyword density in the used text. In this way, the search engine increases the rating of the page. If the frequency of use is too high, there is a possibility of being treated as spam (SPAM), so do not use keywords more than necessary.
[0011]
When a web page is linked from another web page, the search engine increases the rating of the page. When linking, it is good to link from sites with high evaluation. In addition, it is preferable to link from a website site map, a category classification page, a ranking page, or the like.
[0012]
In addition, if there is a link collection page of a highly evaluated site that is displayed at the top of the search result, the search engine increases the evaluation of the page, so it is also preferable to provide such a link collection.
[0013]
Each HTML tag has an original description method. For example, the <title> tag is a page title, and the <h1> and <h2> tags are headings. Search engines increase the rating of a page when HTML tags are used for meaningful structuring rather than for adjusting where they are displayed in the browser.
[0014]
Therefore, it is also desired to convert to such a page and output it.
[0015]
Web pages are loaded in a location that is easy for humans to read, and search engines increase the rating of the page.
[0016]
The present invention will be further described.
[0017]
According to one aspect of the present invention, in order to achieve the above-described object, the document output device: the path name and the argument of the program expressed using the argument delimiter included in the URL of the received HTTP request A web server body that receives and generates a document and outputs it by an HTTP response; a path of a corresponding program in which a predetermined path name included in an HTTP request sent from a user is expressed using an argument delimiter A first conversion means that converts the name and argument into a web server main body and supplies the first and second arguments; a program path expressed using an argument delimiter included in the URL of the HTTP response output from the web server main body Article including a predetermined URL as the anchor information; name and arguments, and the second converting means for converting the pathname without argument delimiters There are, the predetermined URL, the above from the URL of the web server main body H TTP request is Ru are plan delivered, the path of the contained in the URL of the HTTP request, the program, labeled with the arguments Separator A document storage means for storing the document , which is a URL formed by converting a name and an argument into a corresponding path name without an argument delimiter; an HTTP request for the document stored in the document storage means The output is based on.
[0018]
In this configuration, while a web page or the like is dynamically generated, a web page or the like can be taken out by designating a path name as if the external web page is taken out externally. A document (web page) including a URL including a path name used to extract them as a link (anchor information) is prepared and can be browsed. Such a document can be configured as a site map, a category index, and an access ranking table.
[0019]
Therefore, while dynamically generating a web page, there is no restriction on the total number of collections by the traveling robot, and the number of links increases. As a result, it can be registered in the search engine index with higher evaluation. I can expect.
[0020]
Note that according to another invention relating to the present invention, in order to achieve the above object, dynamically statically in relation to the system to generate a web page containing the anchor information to the dynamic web pages In a method for synthesizing a web page: referencing a database used to generate a dynamic web page or an equivalent database to determine a URL including an argument representation of the dynamically generated web page; A step of converting the URL into a URL integrated with a path name including an argument not including an argument notation; and a step of generating a web page including the converted URL as anchor information are executed.
[0021]
An equivalent database is, for example, a copy of the original database.
[0022]
This web page is arranged in a default route or the like of a system (web server) that generates the dynamic web page. You may arrange | position to the web server etc. of the same domain name.
[0023]
In this configuration, a static web page including a link to a dynamic web page can be published, and as a result, more dynamic web pages can be targeted by search engine index information by a robot. Be expected.
[0024]
The present invention can be realized not only as an apparatus or a system but also as a method, and at least a part thereof can be implemented as a program.
[0025]
The foregoing aspects of the invention and other aspects of the invention are set forth in the appended claims and will be described in detail below with reference to examples.
[0026]
DETAILED DESCRIPTION OF THE INVENTION
Examples of the present invention will be described below.
[0027]
FIG. 1 shows an embodiment in which the embodiment of the present invention is applied to an electronic commerce system. Of course, it is applicable to various systems. In this embodiment, an already-operated electronic commerce system is adapted using the present invention to construct a new system. Of course, everything may be newly constructed.
[0028]
In FIG. 1, an electronic commerce site 10 of this embodiment is a web-based system, and can be accessed by a client device 40 via a communication network (not shown) such as the Internet. An HTTP request is sent from the client device 40 and a corresponding HTTP response is sent from the electronic commerce site 10. The user can browse transaction contents and execute transactions using the client device 40. The electronic commerce site 10 includes an existing operation system 20, a conversion processing unit 30, a web cache server 31, a category index / site map storage unit 32, and the like added by applying the present invention.
[0029]
The existing operation system 20 generates a dynamic web page, and includes a web server 21, a CGI processing unit 22, a product database 23, and the like as is well known. The existing operation system 20 has been operated alone as an electronic commerce site. In the existing operation, the web server 21 receives the path name of the CGI program (CGI processing unit 22) and the argument to be transferred to it, and transfers the argument to the CGI processing unit 22. The CGI processing unit 22 makes a search request to the product database (database management system) 23 based on the argument, receives the returned search result, and dynamically generates a web page based on the search result to generate the web server 21. To return to.
[0030]
When the web cache server 31 receives an HTTP request from the client device 40 and caches the corresponding HTTP response, the web cache server 31 returns the cached HTTP response to the client device 40 and does not cache the HTTP response. The HTTP request is passed to the web server 21 of the existing operation system 20 via the conversion processing unit 30.
[0031]
As shown in FIG. 2, the conversion processing unit 30 includes functional elements of a path name / argument conversion unit 301, an argument / path name conversion unit 302, and a page conversion unit 303. As shown in FIG. 5A, the HTTP request sent from the web cache server 31 to the path name / argument conversion unit 301 does not include an argument notation in the URL as in the case of requesting a static page. The path name / argument conversion unit 301 converts this URL into one with an argument notation as shown in FIG. 5B and passes it to the web server 21 of the existing operation system 20. As a result, the existing operation system 20 generates a dynamic web page and sends it to the conversion processing unit 30 by an HTTP response. The URL of this HTTP response is accompanied by argument notation.
[0032]
The argument / path name conversion unit 302 of the conversion processing unit 30 integrates the argument notation of the URL (see FIG. 5B) in the HTTP response into the path name, and converts it as shown in FIG. In addition, the page conversion unit 303 of the conversion processing unit 30 converts an element of a dynamic web page, for example, a part marked up with a tag. Specifically, when nothing is included in the title tag or header tag, a character string (for example, a product name, a product category, other product attributes, etc.) serving as a keyword is inserted. When a link (anchor information) including an argument notation is embedded, it is integrated into a path name. Furthermore, a link (anchor information) to a product category page, a site map, or the like is appropriately inserted. This process can be performed by a normal character string replacement process or the like. The HTTP response including the converted URL and page is sent to the client device 40 via the web cache server 31 and simultaneously cached by the web cache server 31. When the argument is a product ID, it is preferably converted into a corresponding character notation (alphabet notation) when integrating the path name. Various processes of the conversion processing unit 30 can be realized by, for example, an ordinary text processing program, and the conversion rules are described by regular expressions, for example.
[0033]
The category index / site map storage unit 32 is arranged under the root directory of the web server 21 and includes a web page group constituting a category index and a web page group constituting a site map. For example, the category index is hierarchically configured from the product top page as shown in FIG. 6 and is linked to reach each product page. The category index and the site map are composed of static web pages, and can be browsed using an HTTP request specifying a normal corresponding path name. The category index / site map storage unit 32 may include a web page of an access ranking list.
[0034]
3 and 4 show how to prepare a static web page to be stored in the category index / site map storage unit 32. FIG. In FIG. 3, the product database 33 is a copy of the product database 23 of FIG. Of course, the product database 23 itself may be used. The product database 33 (same for the product database 23) manages various attributes (product ID, price, manufacturer, color, product category, etc.) related to the product, addresses of image information, and the like. The static page generation unit 35 refers to the configuration of the data record in the product database 33 and generates a web page that forms a category index as shown in FIG. That is, configuration information (including template information, for example) for configuring a static page, such as the configuration of a data record, is stored in the web page configuration information storage unit 34, and the static page generation unit 35 The URL (including argument notation) of a web page (for example, a product page) that is scheduled to be dynamically generated by accessing the product database 33 while referring to the configuration information is specified (step S10 in FIG. 4). This URL is converted into a URL in which an argument is integrated with a path name (step S11), and thereafter, a static web page of a predetermined category hierarchy is generated in which the converted URL is embedded as anchor information (same as above). Step S12). Thereafter, the generated static web page is arranged in the category index / site map storage unit 32 (step S13). This process is executed for all pages of the category index (step S14). Similarly, a static web page of the site map and a static web page of the access ranking table are generated and stored in the category index / site map storage unit 32 in the same manner.
[0035]
The administrator can edit the static web page using the editing unit 36.
[0036]
Note that it is possible to specify up to which path the web cache server 31 caches using the user interface.
[0037]
In this embodiment, when the patrol robot of the search engine fetches the category index and the web page of the site map, the product page is sequentially accessed. Since any page basically does not include “?” In the argument notation in the anchor information, it can be expected that all product pages are captured. Further, since the category index or the web page of the site map and the product page are linked directly or indirectly (via the product category page), it can be expected that a high ranking is given.
[0038]
In this embodiment, the web page of the electronic commerce site 10 is expected to be accessed from a search engine search so that the web page is efficiently registered in the search engine index. In this embodiment, as shown in FIG. 7, the HTTP request log is recorded and managed in the access history storage unit 32, and the referrer information of the HTTP request (the HTTP request made immediately before by the user who accessed the website). Information), the access statistical information generation unit 37 performs statistical processing on the search keyword hit by the website and verifies what is a valid keyword. As a result, the page conversion unit 303 of the conversion processing unit 30 is replaced. It can be used to adapt rules and the like.
[0039]
In addition, this invention is not limited to the above-mentioned Example, A various change is possible. For example, an application server may be used instead of the CGI processing unit. Although the conversion processing unit 30 is arranged on the client side of the web server 21, all or part of the conversion processing unit 30 is included in the web server 21 or replaced with the module, and the web server 21 and the CGI processing unit 22 are included. Of course, it may be arranged between. Moreover, you may comprise the part except the existing operation system 20 among the electronic commerce sites 10 independently.
[0040]
In this embodiment, only the web server 21 is used, but two or more web servers are used, and a static web page in the category index / site map storage unit 32 is taken out by a web server other than the web server 21. good. Moreover, it is not necessary to use a web cache server.
[0041]
In this embodiment, the URL of the dynamic web page that the user has taken out using the existing operation system 20 is registered in the web browsing software, and the newly reconstructed electronic commerce site 10 can be accessed. is assumed. In this case, processing may be performed so that there is no corresponding page, or for an HTTP request accompanied by argument notation, a pre-processing for integrating this into a path name may be performed.
[0042]
In addition, the present invention can be widely applied to systems that dynamically generate web pages, and can be applied to systems other than electronic commerce systems.
[0043]
Moreover, you may make it apply this invention selectively to a part of dynamic web page. Only a part may be viewed as a static web page, and the other part may be handled as a dynamic web page as it is. Such an application part may be specified by a path name using a user interface, for example.
[0044]
Further, the present invention can be widely applied to a document displaying a browsing screen, and it should be understood that a web page widely includes not only an HTML page but also XML, HXML, and the like.
[0045]
【The invention's effect】
As described above, according to the present invention, a document output device that generates a dynamic web page looks as if it is a document output device that generates a static web page from the outside, and the anchor information of each page is further displayed. By holding the embedded page, it can be expected to be registered efficiently in the index of the search engine, and it can also be expected to improve the ranking of search results.
