Abstract:
We describe an on-going work on the semi-automatic derivation of ontological structures from text. Hereby, we first apply on plain text pattern-based linguistic heuristics, for identifying relevant segments out of which candidate ontology classes and relations can be derived. The second step proposes a consolidation of those candidates on the basis of a partial linguistic and semantic analysis of the textual context of the segments. The last step is dealing with the extension of the derived ontology structures. We use for this a constituency and dependency analysis of the textual segments selected in steps 1 and 2. We show how these three steps support in different but related ways the derivation of ontology components from text.
