MRD Structure
The internal structures of current Machine Readable Dictionaries (MRDs) usually merely mimic the structure of the printed form (Boguraev 1990)
Some work, notably WordNet (Miller 1995) has involved a fundamental rethinking of dictionary content and organisation (in WordNet, organisation via “synsets” which are related via links of part, subkind, opposite)
But there has been little in the way of software to make such research truly usable by different communities of users.
