'''Leveraging Wikipedia Characteristics for Search and Candidate Generation in Question Answering''' - scientific work related to [[Wikipedia quality]] published in 2011, written by [[Jennifer Chu-Carroll]] and [[James Fan]].

== Overview ==
Most existing Question Answering (QA) systems adopt a type-and-generate approach to candidate generation that relies on a pre-defined domain [[ontology]]. This paper describes a type independent search and candidate generation paradigm for QA that leverages [[Wikipedia]] characteristics. This approach is particularly useful for adapting QA systems to domains where reliable answer type identification and type-based answer extraction are not available. Authors present a three-pronged search approach motivated by relations an answer-justifying title-oriented document may have with the question/answer pair. Authors further show how Wikipedia metadata such as anchor texts and redirects can be utilized to effectively extract candidate answers from search results without a type ontology. Authors experimental results show that strategies obtained high binary recall in both search and candidate generation on TREC questions, a domain that has mature answer type extraction technology, as well as on Jeopardy! questions, a domain without such technology. Authors high-recall search and candidate generation approach has also led to high overall QA performance in Watson, end-to-end system.
