Dealing with ambiguities in an answer extraction system

Abstract

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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
