Abstract

This paper proposes an information retrieval process that employs a relevance feedback approach based on implicit evidences provided by contextual information and explicit evidences provided by the user behavior during interaction. This process takes advantage of semantic information processing enabled by the use of ontologies to build semantic indexes, to represent context and domain knowledge and to aid interactions mediated by mobile devices.
