Probabilistic Techniques for Phrase Extraction.
Feng, Fangfang; Croft, W. Bruce
Information Processing & Management, v37 n2 p199-220 Mar 2001
This study proposes a probabilistic model for automatically extracting English noun phrases for indexing or information retrieval. The technique is based on a Markov model, whose initial parameters are estimated by a phrase lookup program with a phrase dictionary, then optimized by a set of maximum entropy parameters.
