837 :    
838 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
839 :     files. See the questionnaire data/Umfrage.csv for such an example.
840 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
841 : feinerer 22
842 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
843 : feinerer 21 matrix is now possible.

846 :    
847 :     * R/textdoccol.R: One can build term-document matrices if
848 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
849 :     document collection with it.
850 :    
851 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
852 :    
853 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
854 :    
855 :     * R/textdoccol.R: We now can read in a whole XML file with several
856 :     news items.
857 :    
858 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
859 :    
860 :     * R/textdoccol.R: Set up an S4 class for a collection of text
861 :     documents. A first attempt to read in XML input (like the RCV1
862 :     set) was made.
863 :    
864 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
865 :     some accessor functions.
866 :    
867 :     * data/newsitem.xml: Added this XML file for testing purposes. It
868 :     contains a single news item from the Reuters Corpus Volume 1
869 :     (RCV1) XML set.

871 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
872 :    
873 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
874 :     textmatrix as k-means clustering provided by R (kmeans) now works on
875 :     this textmatrix. The result is a k-means text clustering with a
876 :     similarity measure based upon word frequences.

878 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
879 :    
880 :     * R/textmatrix.R: Adapted the preprocessing code from the R
881 :     package "lsa" written by Fridolin Wild to build a document text matrix.
882 :    
883 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
