custom ordering on digital library information retrieval
Suitable ranking of results is crucial when searching large collections available in Digital Libraries (BDs) so the first document presented to users are the most relevant to a search criterion. Several works acknowledge the need to consider the user's preferences for ranking search results, but it is hard to determine the user profile model and how much weight individual preferences should have in each application. This paper proposes a technique for re-ordering the results of searches on BDs that combines the relevance of each result item for the posed query with the individual user's preferences. In this proposal, the user profile maintains the characteristics of the documents that he/she prefers. This profile is built dynamically and transparently, based on the values of some metadata elements describing the documents accessed by the user. The proposal was validated in a BD providing access to a collection of literature documents.
