7 :    
8 :     * src/: Various splits can now be easily created for the
9 :     Reuters21578 data set.

20 :    
21 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
22 :     files. See the questionnaire data/Umfrage.csv for such an example.
23 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
24 : feinerer 22
25 : feinerer 21 * Changed class interfaces in various files. Weighting of the text
26 :     matrix is now possible.

28 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
29 :    
30 :     * R/textdoccol.R: One can build term-document matrices if
31 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
32 :     document collection with it.
33 :    
34 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
35 :    
36 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
37 :    
38 :     * R/textdoccol.R: We now can read in a whole XML file with several
39 :     news items.
40 :    
41 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
42 :    
43 :     * R/textdoccol.R: Set up an S4 class for a collection of text
44 :     documents. A first attempt to read in XML input (like the RCV1
45 :     set) was made.
46 :    
47 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
48 :     some accessor functions.
49 :    
50 :     * data/newsitem.xml: Added this XML file for testing purposes. It
51 :     contains a single news item from the Reuters Corpus Volume 1
52 :     (RCV1) XML set.
53 :    
54 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
55 :    
56 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
57 :     textmatrix as k-means clustering provided by R (kmeans) now works on
58 :     this textmatrix. The result is a k-means text clustering with a
59 :     similarity measure based upon word frequences.
60 :    
61 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
62 :    
63 :     * R/textmatrix.R: Adapted the preprocessing code from the R
64 :     package "lsa" written by Fridolin Wild to build a document text matrix.
65 :    
66 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
67 :
