The work here presented(More)

Query expansion techniques like pseudo-relevance feedback (PRF) and document clustering techniques(More)
The frame-based knowledge representation model adopted in IDHS (Intelligent Dictionary Help System) is described in this paper. It is used to represent the lexical knowledge acquired automatically from a conventional dictionary. Moreover, the enrichment processes that have been performed on the Dictionary Knowledge Base and the dynamic exploitation of this(More)
