Context Related Derivation of Word Senses

Real applications of natural language document processing are very often confronted with domain specific lexical gaps during the analysis of documents of a new domain. This paper describes an approach for the derivation of domain specific concepts for the extension of an existing ontology. As resources, we need an initial ontology and a partially processed corpus of a domain. We exploit the specific characteristics of the sublanguage in the corpus. Our approach is based on syntactic structures (noun phrases) and compound analysis to extract information required for the extension of GermaNet’s lexical resources.
