    Abstract
    Examines techniques for automatically generating domain vocabularies from large text collections. Focuses on the problem of generating multi-word vocabulary terms (specifically pairs). Discusses statistical issues associated with word co-occurrences likely to be of use in a natural language interface. Provides a more objective evaluation of the selection procedures. As substantial experimentation with subjects using a working query system is absent, all evaluation is necessarily subjective. Uses surrogate for experimentation by relying on pre-existing dictionaries as indicators of domain relevance
