The unprecedented growth in the volume of online information has led to an information explosion which has made producing queries over this information difficult. In this paper, we examine an automated mechanism which allows users to access this information in a structured manner by analyzing unstructured text by domain-specific ontologies, annotating these documents using XML tags and using specific query processing techniques. Our approach is to use focused linguistic techniques over a limited context of an ontology for the identification and annotation of basic concepts and relationships in textual documents. These annotated documents can then be related to other structured information sources specified over similar ontologies.
