Towards Acquisition of Taxonomic Inference

Piroska Lendvai

Eighth International Conference on Computational Semantics (IWCS-8 2009)
Tilburg University, Netherlands, January 7-9, 2009


On a pilot corpus of Dutch medical encyclopedia texts, we focus on the mechanism taxonomic inference that involves extraction of taxonomic co-hyponym terms, and the domain-specific hypernym relation that coordinates these in the form of a textual hypothesis, from a document. The inference elements are acquired by syntactic and semantic alignment, additionally driven by document structure. From the terms and the related hypothesis we harvest lexical patterns, which are linked to annotated domain concepts. The inference method is bootstrapped and transferred to unstructured documents to detect new co-hyponym terms and their relations.
