Abstract

Many existing techniques for term extraction are heuristically-motivated and criticised as ad-hoc. The definitions and assumptions critical to set the boundary for the effectiveness of the techniques are often implicit and unclear. Here we present a probabilistic framework for measuring termhood to address the lack of mathematical foundation in existing techniques.
