... Hypothesis 1 Resolving lexical ambiguity will lead to an improvement in retrieval performance. There are many issues involved in determining how word senses should be used in information re- ... distinctions, and the type of distinctions required in information retrieval is an open question.

... as strings (Eisner, 1997). In general, an OT grammar consists of 4 com- ponents: a constraint ranking, a harmony ordering, and generating and pronouncing functions. The con- straint ranking is ... Following Eisner (1997), each candidate (x, z) is also represented as a string y. The notation (x, z) that we have been using so far for candidates is actually misleading, since in fact the...
