Constructing personal digital library by multi-search and customized category

The current search tools for retrieving information on WWW are not suitable for building customized information repository because these search tools are designed for general users with the result of only an unstructured collection of documents. In this paper, we present a personal digital library capable of eficiently retrieving information on the World Wide Web. We adopt several new strategies to overcome the shortcomings of current tools. The j r s t strategv, Class fication, merges and organizes the retrieved documents to put them in a structural, hierarchical fFame. The second strutegy, User Profile, saves time and bandwidth for the access of the documents and permits the users to build their own customized category structure. The third strategy, MultiSearch, capitalizes on the power of multiple search engines to broaden the domains of information sources and alleviate the overloading of a single search engine. Furthermore, we derive in detail the techniques for speeding up the iterative process of clustering.
