Abstract

Systems and methods are provided for non-monotonic recognition of phrasal terms. Phrasal terms are identified from a corpus of written materials and ranked based on, for example, a mutual rank ratio. The phrasal terms are sequentially selected and a determination is made as to whether to accept or reject the selected phrasal term based on at least one predetermined criteria. The ranking of the phrasal terms may also rely on linguistic support to reduce duplication of phrasal terms and to distinguish different confidence levels for identified and accepted phrasal terms.
