Information retrieval system using Multiwords Expressions (MWE) as descriptors

This paper aims to propose an alternative method for retrieving documents using Multiwords Expressions (MWE) extracted from a document base to be used as descriptors in search of an Information Retrieval System (IRS). In this sense, unlike methods that consider the text as a set of words, bag of words, we propose a method that takes into account the characteristics of the physical structure of the document in the extraction process of MWE. From this set of terms comparing pre-processed using an exhaustive algorithmic technique proposed by the authors with the results obtained for thirteen diff...
