Information Extraction and Database Techniques: A User-Oriented Approach to Querying the Web

摘要

We propose a novel approach to querying the Web with a system named AKIRA (Agentive Knowledge-based Information Retrieval Architecture) which combines advanced technologies from Information Retrieval and Extraction together with Database techniques. The former enable the system to access the explicit as well as the implicit structure of Web documents and organize them into a hierarchy of concepts and meta-concepts; the latter provide tools for data-manipulation.
