How to deal with ambiguities while parsing
Hidetosi Sirai · 1980
It is difficult for a natural language understanding system (NLUS) to deal with ambiguities. There is a dilemma: an NLUS must be able to produce plausible interpretations for given sentences, avoiding the combinatorial explosion of possible interpretations. Furthermore, it is desirable for an NLUS to produce several interpretations if they are equally plausible. EXAM, the system described in this paper, is an experimental text understanding system designed to deal with ambiguities effectively and efficiently.
