Some Patterns Observed in the Contextual Specialization of Word Senses

摘要

A criterion is developed for marking those sentences which should be indicated as being contextually dependent in auto-abstracting and mechanical paraphrasing applications. A procedure is described for choosing which expressions in the sentences so marked chiefly account for the contextual dependence of those sentences. The environments of these expressions were studied to see whether they exhibited any formal regularities which could be exploited in writing programs to recognize contextually dependent sentences in a text and locate some elements of their linguistic context which could be used to reduce their contextual dependence significantly.
