Decision Trees For Document Classification
<p>Hi I wanted to know that is it possible to use decision trees for document classification and if yes then how should be the data representation be? 
I know the use of R package <a href="http://cran.r-project.org/web/packages/party/index.html" rel="nofollow noreferrer">party</a> for Decision Trees. </p>
