This paper describes an algorithm that can be used to improve the quality of multiword expressions extracted from documents. We measure multiword expression quality by the “usefulness” of a multiword expression in helping ontologists build knowledge maps that allow users to search a large document corpus. Our stopword based algorithm takes ngrams extracted(More)
