Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Web page search method for searching Web pages written in multiple languages, We.
The present invention relates to a b-page search system and a web page search program.

[0002]

2. Description of the Related Art The spread of today's global Internet technology has made it possible to collect information globally. However, Web pages (homepage) on the Internet
Is predominantly in local language. Therefore,
There is a language barrier for a user to collect information from a web page in a local language and understand the content of that information. Thus, in the case where the user himself / herself cannot understand the language used in the Web page, the following method is generally used in order to remove the language barrier of the user most quickly and easily.

First, when the user knows the site to be browsed in advance, the user can directly access the site by inputting the URL of the site. In this case, the web page of the site accessed by the user is displayed on the user's terminal. Here, the Web page is written in a local language (for example, German). When the user cannot understand the contents of the local language Web page, the user machine-translates the local language Web page into a predetermined language (for example, Japanese) using translation software or the like. A user browses a machine-translated Web page and collects information.

The next method is a method in which a user surfs the Internet (translation browsing) while translating a Web page. In this case, the user sequentially displays the linked web pages on the terminal and browses them. At this time, when a web page written in a local language (eg, German) that cannot be understood is displayed, the user machine-translates the web page into a predetermined language (eg, Japanese) using translation software or the like. . The user browses the machine-translated Web page and continues surfing the Internet until he / she reaches the Web page on which the desired information is posted.

As another method, there is a method in which a user inputs a keyword (search word) to a search site and a target Web page is searched based on the input keyword. In this case, the user first inputs a keyword in a predetermined language (for example, Japanese) into the search site. The entered keywords are translated into multiple local languages (eg German, English). Here, a plurality of Web page search systems (search engines) are provided for each local language. Web page search system for each local language, translated local language (German or English)
The corresponding Web page is searched based on the translated word.
Such a web page search method is called multilingual distributed information search.

A web page search system generally searches a web page in the same local language as the translated word. For example, when the translation word is German, the Web page search system searches for a German Web page. The user causes the terminal to display the retrieved Web page in the local language, and uses translation software or the like to machine translate the Web page into a predetermined language (for example, Japanese). Then, the user browses the machine-translated Web page and collects information.

[0007]

The conventional method as described above has the following problems. The first method is based on the assumption that the user knows the site to be browsed in advance. However, there are actually few cases where the site you want to browse is known in advance. Therefore, it is not a method that the user can frequently use as an information collecting means.

In the second method, a Web page in a language other than a language understandable by the user is randomly browsed and information is collected while being translated. However, in the case of this method, the user cannot always reach the Web page on which the desired information is posted. Further, since the user also has to translate a Web page on which information other than the intended information is posted, the work of browsing and translating the Web page was inefficient.

In the third method, it is possible to use a foreign search engine as the Web page search system. However, not everyone can easily search for information using foreign search engines. Users are required to have the following minimum language knowledge. That is, the input to the search engine for each local language is
These are the translated local language keywords. Also, the search results by the search engine are displayed in the local language. Therefore, the user is required to have a rudimentary knowledge of the local language, for example, know-how such as character drawing. Many people have that level of knowledge about English, but many do not even have the above knowledge of other languages.

W based on the search result of the search engine
Browsing of eb pages also involves Internet surfing of Web pages machine-translated from local languages. Therefore, the problem due to the above-mentioned second method also occurs.

Furthermore, in multilingual distributed information retrieval,
The keyword (search word) is input in any language desired by the user (for example, Japanese). On the other hand, the search engine for each local language, based on the translated keywords,
Perform each search. Therefore, the search result by each search engine is displayed for each search engine. That is, as many search results as the number of languages in which the keyword is translated are displayed. Therefore, the user has to browse the search results for each local language, which requires a great deal of effort.

The present invention has been made to solve the above problems, and requires no language knowledge for the user, and can be efficiently operated by a simple operation in any language W.
An object is to obtain a web page search method, a web page search system, and a web page search program that can search and browse eb pages.

[0013]

In order to achieve the above object, the web page search method of the present invention makes a web page search request when a web page search request for a predetermined keyword transmitted from a client terminal is received. The specified language specified by the user is recognized from the included language information, and the index of the specified language corresponding to the predetermined keyword included in the web page search request is searched for from the index stored in advance and read out.
