Ontology enrichment with texts from the WWW
Andreas Faatz, Ralf Steinmetz · TUbilio (Technical University of Darmstadt) · 2002
The following paper explains, how we can enrich an existing ontology by mining the WWW. The use of such an ontology may be manifold, for example as a component of information systems or multimedial repositories. The enrichment process is based on the comparison between statistical information of word usage in a large text collection, a so called text corpus, and the structure of the ontology itself. The text corpus will be constructed by using the vocabulary from the ontology and querying the WWW via Google. We define similarity measures by optimising their parametrisation and examine the central properties of the enrichment approach - along with the presentation and evaluation of experimental results. Parametrisation of a similarity measure means assigning weights to each word collocation feature we first check in the text corpus and thereafter integrate into the representation of a word or a concept.
