Text filtering in MUC-3 and MUC-4
David D. Lewis, Richard M. Tong · 1992
One of the changes from the Third (MUC-3) to the Fourth (MUC-4) Message Understanding Conference was the emergence of text filtering as an explicit topic of discussion. In this paper we examine text filtering in MUC systems with three goals in mind. First, we clarify the difference between two uses of the term "text filtering" in the context of data extraction systems, and put these phenomena in the context of prior research on information retrieval (IR).
