Abstract
A method for establishing controlled vocabularies is proposed, based on the analysis of natural language as used in particular areas of expertise (sublanguage). The proposed vocabulary includes terms for relations as well as terms for objects, organized into class hierarchies. The method provides a controlled technique for eliciting distinctions about terms from experts, and aids in minimizing redundancy in the vocabulary. The vocabulary can be represented and managed using frames, semantic nets, or object-oriented techniques. The approach suggests a way of integrating free text and controlled terms in medical information systems through the intermediate structures of sublanguage.
