824 :    
825 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
826 :     files. See the questionnaire data/Umfrage.csv for such an example.
827 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
828 : feinerer 22
829 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
830 : feinerer 21 matrix is now possible.

833 :    
834 :     * R/textdoccol.R: One can build term-document matrices if
835 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
836 :     document collection with it.
837 :    
838 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
839 :    
840 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
841 :    
842 :     * R/textdoccol.R: We now can read in a whole XML file with several
843 :     news items.
844 :    
845 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
846 :    
847 :     * R/textdoccol.R: Set up an S4 class for a collection of text
848 :     documents. A first attempt to read in XML input (like the RCV1
849 :     set) was made.
850 :    
851 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
852 :     some accessor functions.
853 :    
854 :     * data/newsitem.xml: Added this XML file for testing purposes. It
855 :     contains a single news item from the Reuters Corpus Volume 1
856 :     (RCV1) XML set.

858 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
859 :    
860 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
861 :     textmatrix as k-means clustering provided by R (kmeans) now works on
862 :     this textmatrix. The result is a k-means text clustering with a
863 :     similarity measure based upon word frequences.

865 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
866 :    
867 :     * R/textmatrix.R: Adapted the preprocessing code from the R
868 :     package "lsa" written by Fridolin Wild to build a document text matrix.
869 :    
870 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
871 :
