Data Set Used
The increasing number of digitized texts presently available notably on the Web has developed an acute need in text mining techniques. Clustering systems are used more and more often in text mining, especially to analyze texts and to extract knowledge they contain. With the availability of the vast amount of clustering algorithms and techniques, it becomes… (More)
This paper deals with our research on unsupervised classification for automatic language identification purpose. The study of this new hybrid algorithm shows that the combination of the Kmeans and the artificial ants and taking advantage of an n-gram text representation is promising. We propose an alternative approach to the standard use of both algorithms.… (More)
Dans cet article, nous proposons la méthode des SOM (cartes auto-organisatrices de Kohonen) pour la classification non supervisée de documents textuels basés sur les n-grammes. La même méthode basée sur les synsets de WordNet comme termes pour la représentation des documents est étudiée par la suite. Ces combinaisons sont évaluées et comparées.
With the great and rapidly growing number of documents available in digital form (Internet, library, CD-Rom…), the automatic classification of texts has become a significant research field and a fundamental task in document processing. This paper deals with unsupervised classification of textual documents also called text clustering using Self-Organizing… (More)
Given the incessant growth of documents describing the opinions of different people circulating on the web, including Web 2.0 has made it possible to give an opinion on any product in the net. In this paper, we examine the various opinions expressed in the tweets and classify them (positive, negative or neutral) by using the emoticons for the Bayesian… (More)
The classification of textual documents has been the subject of many studies. Technologies like the web and numerical libraries facilitated the exponential growth of available documentation. The classification of textual documents is very important since it allows the users to effectively and quickly fly over and understand better the contents of large… (More)
