Abstract

This work presents the specification of experiments that apply query expansion techniques with pseudo relevance feedback to TR+ Model in information retrieval. The TR+ Model uses terms and binary lexical relations (BLRs) for indexing and searching of texts in Portuguese. The experiments add (or remove) new terms or BLRs to the original query in order to study the effects of those changes in document retrieval.
