Edson Marchetti da Silva, Renato Rocha Souza · 2013
This paper aims to compare the results obtained in the retrieval of documents in acorpus using as calculating the similarity function three different techniques adapted for useas descriptors Multi Words Expressions (MWE) extracted from a reference document. Thetechniques tested were Term Frequency-Inverse Document Frequency (TF-IDF), CosineSimilarity Vector (CVS) and Okapi BM25. The goal is to propose an alternative means ofInformation Retrieval Systems (IRS) find in a digital database compound of thesis,dissertations and articles, similar documents from a reference document informed by user. Inthis sense, are considered some structural features of the document. As results, are presented acomparison and analysis of empirical results obtained.
