Embodiment Construction

[0026] image 3 A schematic diagram of a system showing an embodiment of the present technology. For example, a computer network 1 such as the Internet or a Local Area Network (LAN) is connected to a plurality of user terminals 3 , a search processing server 5 that executes main processing of the present embodiment, and a known search engine 7 that executes database searches.

[0027] The search engine 7 is connected to a database (DB) 71 in which files themselves are stored, for example, index data of multiple files (web pages, data, etc.) stored by multiple servers connected to the network 1 . The configuration of the search engine 7 and the DB 71 managed by the search engine 7 is not the main part of the present embodiment, but is well known, and therefore will not be described in detail.

[0028] The search processing server 5 also includes a user interface unit 51 serving as an interface with the user terminal 3, a search interface unit 53 serving as an interface with th...

Abstract

The result of initial search is acquired by search using a search keyword inputted by a searcher. On the other hand, an extended search keyword associated with the search keyword is extracted, and the number of corresponding documents or the frequency of appearance in the result of the initial search is counted. When the number of corresponding documents or the frequency of appearance is not larger than a predetermined value (including 0), the extended search keyword is adopted, and the result of the extended search is acquired by search using the search keyword and the extended search keyword adopted. Then, the result of the initial search and that of the extended search are presented to the searcher. Thereby, such a document as is buried in the result of the initial search can be presented to the searcher.

Description

technical field [0001] The present technology relates to keyword retrieval technology. Background technique [0002] Conventionally, when a database search was performed using a keyword such as "apple", it was assumed that figure 1 search results as shown. from figure 1 It can be seen that the top 1,000 search results all contain documents about "apple juice" and "applesauce". As a search result, the search engine usually limits the number of returned files, and the searcher cannot access, for example, the 1001st and later files, such as files containing "apple pie". [0003] In addition, there is a conventional technique in which a related word related to an input keyword is extracted from a related dictionary in which related words are stored for each keyword in advance, and a search is performed using the extracted related words. The extracted related words are extracted according to a predetermined priority or the like. However, after obtaining figure 1 In the case...
