Abstract
The NLM/AHCPR Large-Scale Vocabulary Test data set was used to investigate the nature of ad hoc relationships formed when users mapped broader to narrower terms as the closest available conceptual match. Among the 1,162 term pairs examined, the most common semantic differences were based on anatomical or functional distinctions between the terms. As expected, modification accounted for the majority of syntagmatic specifications characterized, but hierarchical specification accounted for over a fifth of the mappings
