    Hi,

    do you know the video tutorials about RapidMiner on http://rapid-i.com/content/view/189/212/lang,en ? There are also some videos about text mining.

    Best, Marius

    Thanks Marius. The truth is that the videos did not help me much. I did not know what attributes using the k-means to generate the classification of texts. I generate the frequency matrix and then apply the k-means, this genre I cluster. And the classification was relatively good. I wanted that I would group by topic.

    My question is:
    Is there another way of classifying or grouping texts? for best results.

    There is also Tree cluster methods as well as EM (Expectation Maximization) clustering; see variable clustering methods and data mining.  I don't know if such an operator (EM) exists in DM...
    You may have to get creative.
