Fuzzy Clustering of Web Documents Using Equivalence Relations
... Clustering is a useful method for the textual data mining. Traditional clustering technique uses hard clustering algorithm in which each document use to belong to only one and exactly one cluster which creates problem to detect multiple themes of the documents. Clustering can be considered the most ...
