One of the important steps in knowledge discovery is to access the desired information from the large mount of data stored on the WWW. At present, such information can be accessed by a browser itself or by using a keyword search function. However, browsing is a time consuming task where a user must access individual hypertexts one by one. Furthermore, a keyword search is realized in a very limited way ; it does not support database-like queries. In this paper, we provide a smooth, interactive information retrieval framework in which WWW information can be viewed in a global sense and can be handled using a database-like query. Global view displays the link structure of WWW in a hyperbolic tree style where many texts can be accessed easily by changing focus. The query function is useful to filter irrelevant texts and reduce the size of the link structure. These functions are integrated within our browser, allowing us to discover desired texts from large hypertexts incrementally. Typical three web sites were selected to show the performance of the proposed method with improved accuracy and efficiency in information access to the web sites.
