821 : feinerer 799 * Wrote a script for the ModLewis Split for the Reuters-21578 XML
822 : feinerer 29 data set.
823 :    
824 : feinerer 799 * Finished documentation and reordered directory structure. Now "R
825 : feinerer 28 CMD check textmin" works without errors.

827 : feinerer 27 2005-12-04 Ingo Feinerer <h0125130@wu-wien.ac.at>
828 :    
829 :     * src/: Various splits can now be easily created for the
830 :     Reuters21578 data set.

837 :    
838 : feinerer 799 * Wrote R documentation for some classes and methods.

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

849 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
850 :    
851 :     * R/textdoccol.R: One can build term-document matrices if
852 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
853 :     document collection with it.
854 :    
855 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
856 :    
857 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
858 :    
859 :     * R/textdoccol.R: We now can read in a whole XML file with several
860 :     news items.
861 :    
862 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
863 :    
864 :     * R/textdoccol.R: Set up an S4 class for a collection of text
865 :     documents. A first attempt to read in XML input (like the RCV1
866 :     set) was made.
867 :    
868 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
869 :     some accessor functions.
870 :    
871 :     * data/newsitem.xml: Added this XML file for testing purposes. It
872 :     contains a single news item from the Reuters Corpus Volume 1
873 :     (RCV1) XML set.
874 :    
875 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
876 :    
877 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
878 :     textmatrix as k-means clustering provided by R (kmeans) now works on
879 :     this textmatrix. The result is a k-means text clustering with a
880 :     similarity measure based upon word frequences.

882 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
883 :    
884 :     * R/textmatrix.R: Adapted the preprocessing code from the R
885 :     package "lsa" written by Fridolin Wild to build a document text matrix.
886 :    
887 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
888 :
