We are developing corpus-based techniques for iden- tifying semantic relations at an intermediate level of description (more specific than those used in case frames, but more general than those used in tra- ditional knowledge representation systems). In this paperwe describe aclassification algorithmforiden- tifying relationships between two-word noun com- pounds. We find that a very simple approach using a machine learning algorithm and a domain-specific lexical hierarchy successfully generalizes from train- ing instances, performing better on previously un- seen words than a baseline consisting of training on the words themselves.
