Ontology and Information Extraction: a necessary symbiosis
Résumé
This paper argues that the symbiosis between information extraction (IE) and ontologies is a necessary one. On the one hand, IE needs ontologies as part of the understanding process for extracting the relevant information. One the other hand, ontologies can only be effectively and efficiently populated if one resorts to IE techniques. IE and ontology learning and population (OLP) can bearranged in a cyclic process in which IE, as an ontology-driven process, also helps to extend the ontology. In turn, the ontology enriched in this way can be used in the next IE iteration. This paper is illustrated by examples taken in the biology domain, a domain in which there are critical needs for content-based exploration of the scientific literature. It takes the example of the ExtraPloDocs project, which aims at extracting gene-protein interaction information from the bibliography in genomics.
