Genetic Programming-Based Discovery of Ranking Functions for Effective Web Search
2005
Journal of Management Information Systems
Preserved Fulltext
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 ...
