Development of a simple retrieval tool "Wgrep" for WWW information resources and its application for "Vegetable and Fruits Variety Image Database"

Abstract

The number of the information systems on the WWW has been increasing explosively. Most of the information is, however, served on the "page to page" base and the accessibility for the required information is extremely inconvenient. Therefore database systems with retrieval functions are highly required. Though, In fact, several information retrieval systems for WWW have been suggested, it is not easy for non-specialists of database or computer programming to handle them for their own databases.
In this study, we developed a simple retrieval system on WWW called "Wgrep", using Perl language. The installation of "Wgrep" is simple and the development of database systems based on "Wgrep" is easy. To develop database systems with "Wgrep", we don't have to define any special database structures at all. Using "Wgrep", as a sample application, we developed "Vegetable and Fruits Variety Image Database". We found that the performance of "Wgrep" is reasonable and the applicability of it is very high.
