Using a Named Entity Tagger to Generalise Surface Matching Text Patterns for Question Answering
نویسندگان
چکیده
This paper explores one particular limitation common to question answering systems which operate by using induced surface matching text patterns – namely the problems concerned with question specific words appearing within the induced answer extraction pattern. We suggest a solution to this problem by generalising the learned answer extraction patterns to include named entity classes.

متن کاملNamed Entity Disambiguation in a Question Answering System
In this paper, we describe how we use a named entity disambiguation module to merge entities in a question answering system. The question answering system uses a baseline passage retrieval component that extracts paragraphs from the Swedish version of Wikipedia.

This year, we made changes to the passage/sentence retrieval component of ILQUA in handling factoid and list questions. All the other components remain same. ILQUA is an IE-driven QA system. To answer “Factoid” and “List” questions, we apply our answer extraction methods on NE-tagged passages or sentences. The answer extraction methods adopted here are surface text pattern matching, n-gram prox...
