"Term Clustering, weight to matrix transformation"
I want to detect topics of some Persian texts. I computed tfidf measure for my extracted terms by own using .NET programming. I don't know how to do fallowing tasks:
1. convert tfidf values (in database) to matrix form. For clustering of terms (Topic Detection) I need matrix in RapidMiner.
2. how can transpose output matrix as real value for clustering terms instead of documents
Thanks for responding.
