826 : feinerer 25 2005-11-30 Ingo Feinerer <h0125130@wu-wien.ac.at>
827 :    
828 : feinerer 799 * Wrote R documentation for some classes and methods.

831 :    
832 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
833 :     files. See the questionnaire data/Umfrage.csv for such an example.
834 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
835 : feinerer 22
836 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
837 : feinerer 21 matrix is now possible.

840 :    
841 :     * R/textdoccol.R: One can build term-document matrices if
842 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
843 :     document collection with it.
844 :    
845 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
846 :    
847 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
848 :    
849 :     * R/textdoccol.R: We now can read in a whole XML file with several
850 :     news items.
851 :    
852 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
853 :    
854 :     * R/textdoccol.R: Set up an S4 class for a collection of text
855 :     documents. A first attempt to read in XML input (like the RCV1
856 :     set) was made.
857 :    
858 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
859 :     some accessor functions.
860 :    
861 :     * data/newsitem.xml: Added this XML file for testing purposes. It
862 :     contains a single news item from the Reuters Corpus Volume 1
863 :     (RCV1) XML set.

865 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
866 :    
867 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
868 :     textmatrix as k-means clustering provided by R (kmeans) now works on
869 :     this textmatrix. The result is a k-means text clustering with a
870 :     similarity measure based upon word frequences.

873 :    
874 :     * R/textmatrix.R: Adapted the preprocessing code from the R
875 :     package "lsa" written by Fridolin Wild to build a document text matrix.
876 :    
877 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
878 :    
879 : feinerer 799 * Set up the R Text Mining Package infrastructure.
