Dealing with ambiguities in an answer extraction system
Mollà Aliod, D, Hess, M · Zurich Open Repository and Archive (University of Zurich) · 2000
We report on the treatment of ambiguity in ExtrAns, a system that performs an exhaustive linguistic analysis of UNIX manpages to do answer extraction over them. Disambiguation is performed in two stages. The first stage consists of a set of simple rules that delete some of the wrong interpretations that can be spot with purely syntactic information. The second stage extends the use of Brill and Resnik's algorithm to disambiguate several types of attachment ambiguities. Ambiguities that pass the disambiguation procedures are handled by ExtrAns by displaying the answers to the user with graded selective highlighting.
