Robert Krovetz, W. Bruce Croft
Pages: 115-141
DOI: 10.1145/146802.146810
Lexical ambiguity is a pervasive problem in natural language processing. However, little quantitative information is available about the extent of the problem or about the impact that it has on information retrieval systems. We report on an...
