- Abstract
- Provides a linguistic approach to text windowing through an extraction of term variants with the help of a partial parser. The syntactic grounding of the method ensures ehat words observed within restricted spans are lexically related and that spurious word cooccurrences are rules out with a good level of confidence. The system is computationally tractable on large corpora and large lists of terms. Gives illustrative examples of term variation from a large medical corpus. An experimental evaluation of the method shows that only a small proportion of co-occuring words are lexically related and motivates the call for natural language parsing techniques in text windowing
