826 : feinerer 799 * Wrote a script for the ModLewis Split for the Reuters-21578 XML
827 : feinerer 29 data set.
828 :    
829 : feinerer 799 * Finished documentation and reordered directory structure. Now "R
830 : feinerer 28 CMD check textmin" works without errors.

833 :    
834 :     * src/: Various splits can now be easily created for the
835 :     Reuters21578 data set.

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

855 :    
856 :     * R/textdoccol.R: One can build term-document matrices if
857 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
858 :     document collection with it.
859 :    
860 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
861 :    
862 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
863 :    
864 :     * R/textdoccol.R: We now can read in a whole XML file with several
865 :     news items.
866 :    
867 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
868 :    
869 :     * R/textdoccol.R: Set up an S4 class for a collection of text
870 :     documents. A first attempt to read in XML input (like the RCV1
871 :     set) was made.
872 :    
873 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
874 :     some accessor functions.
875 :    
876 :     * data/newsitem.xml: Added this XML file for testing purposes. It
877 :     contains a single news item from the Reuters Corpus Volume 1
878 :     (RCV1) XML set.

881 :    
882 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
883 :     textmatrix as k-means clustering provided by R (kmeans) now works on
884 :     this textmatrix. The result is a k-means text clustering with a
885 :     similarity measure based upon word frequences.

887 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
888 :    
889 :     * R/textmatrix.R: Adapted the preprocessing code from the R
890 :     package "lsa" written by Fridolin Wild to build a document text matrix.
891 :
