The part-whole relation is of special im- portance in biomedicine: structure and process are organised along partitive axes. Anatomy, for example, is rich in part- whole relations. This paper reports pre- liminary experiments on part-whole ex- traction from a corpus of anatomy defi- nitions, using a fully automatic iterative algorithm to learn simple lexico-syntactic patterns from multiword terms. The ex- periments show that meronyms can be ex- tracted using these patterns. A failure analysis points out factors that could con- tribute to improvements in both precision and recall, including pattern generalisa- tion, pattern pruning, and term match- ing. The analysis gives insights into the relationship between domain terminology and lexical relations, and into evaluation strategies for rela...
