Improving Recall for Automatic Information Extraction: Final Status Report

Abstract : This report describes the results of the SBIR Phase I research project on improving recall for automatic information extraction (IE), carried out by Onyx Consulting, Inc. Current IE systems suffer from a number of limitations, especially with respect to the types and amount of knowledge that they bring to bear on the process of extraction. The current effort works on improving the coverage and quality of proper name recognition but also significantly on enhancing the syntactic and semantic knowledge used in extraction. In addition, we also work on resolving multiple references to the same entity in the text. Preliminary testing suggests that the knowledge-intensive methods contribute to enhancing the recall in information extraction.
