Title: Using conceptual categories of questions to measure differences in retrieval performance
Source: Global complexity: information, chaos and control. Proceedings of the 59th Annual Meeting of the American Society for Information Science, ASIS'96, Baltimore, Maryland, 21-24 Oct 1996. Ed.: S. Hardin

Abstract: The form of a question denotes the relationship between the current state of knowledge of the questioner and the propositional content of the question. To assess whether these semantic differences have implications for information retrieval, uses CF database, a 1239 document test database containing titles and abstracts of documents pertaining to cystic fibrosis. The database has an accompanying list of 100 questions which were divided into 5 conceptual categories of questions based on their semantic representation. 2 retrieval methods were used to investigate potential diferences in outcomes across conceptual categories: the cosine measurement and the similarity measurement. The ranked results produced by different algorithms will vary for individual conceptual categories as well as for overall performance
