3. DESAMBIGUAÇÃO DE SENTIDO DE PALAVRAS DIRIGIDA POR TÉCNICAS DE AGRUPAMENTO SOB O ENFOQUE DA MINERAÇÃO DE TEXTOS / WORD SENSE DESAMBIGUATION IN TEXT MINING
This dissertation investigated the application of text mining process from techniques of computing intelligence and machine learning in the problem of word sense ambiguity. The work in the methods of decision support area aimed to develop techniques capable of doing a word meaning disambiguation automatically and also to construct a prototype based on the ap

Multiple comparison procedures are used to compare factorâs levels means. Nevertheless, the most popular tests show problems concerning the ambiguity of results and the control of type I error. Methods based on cluster analysis have been proposed to avoid ambiguity, but they present the problem of being valid only under normality. An alternative to avoid th
