Genetic Programming-Based Discovery of Ranking Functions for Effective Web Search

2005 Journal of Management Information Systems  
In these approaches, the effectiveness of retrieval is limited by the number of ranking functions (or experts) that are used, and by the retrieval effective- ness of individual ranking functions involved  ...  The last column in these tables shows the percentage improvement by our system (GP+S) over the four baselines, and over the performance obtained by vanilla GP, which does not take document structural information  ...

The use of relation matching in information retrieval

Christopher Soo-Guan Khoo
1997 LIBRES: Library and Information Science Research Electronic Journal  
Most information retrieval systems use keywordmatching to identify documents that may be relevant to the user's query. The user's query may contain multiple concepts linked together with relations.  ...  This paper discusses the use of relation matching in information retrievalmatching terms and relations between terms expressed in the query with terms and relations found in the documents.  ...  Four examples of conceptual information retrieval systems are the RIME system (Berrut, 1990) , the patent-claim retrieval system described by Nishida and Takamatsu (1982) , the SCISOR system (Rau, 1987  ...
