Abstract

The h-TechSight Knowledge Management Portal enables support for knowledge intensive industries in monitoring information resources on the Web, as an important factor in business competitiveness. Users can be automatically notified when a change occurs in their domain of interest. As part of this knowledge management platform, we have developed an ontology-based information extraction system to identify instances of concepts relevant to the user’s interests and to monitor them over time. The application has initially been implemented in the Employment domain, and is currently being extended to other areas in the Chemical Engineering field. The information extraction system has been evaluated over a test set of 38 documents and achieves 97% Precision and 92% Recall.
