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

829 :    
830 :     * R/textdoccol.R: One can build term-document matrices if
831 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
832 :     document collection with it.
833 :    
834 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.

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

855 :    
856 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
857 :     textmatrix as k-means clustering provided by R (kmeans) now works on
858 :     this textmatrix. The result is a k-means text clustering with a
859 :     similarity measure based upon word frequences.

862 :    
863 :     * R/textmatrix.R: Adapted the preprocessing code from the R
864 :     package "lsa" written by Fridolin Wild to build a document text matrix.
865 :    
866 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
867 :
