3 :     * inst/doc/clustering.Rnw: Wrote a small vignette to present the
4 :     clustering facilities of this package.
5 :    
6 : feinerer 33 2005-12-15 Ingo Feinerer <h0125130@wu-wien.ac.at>
7 :    
8 :     * R/aobjects.R: Changed package document structure to avoid class
9 :     dependency problems.

13 : feinerer 29 * Wrote a script for the ModLewis Split for the Reuters-21578 XML
14 :     data set.

19 : feinerer 27 2005-12-04 Ingo Feinerer <h0125130@wu-wien.ac.at>
20 :    
21 :     * src/: Various splits can now be easily created for the
22 :     Reuters21578 data set.

25 :    
26 :     * Updated documentation

28 : feinerer 25 2005-11-30 Ingo Feinerer <h0125130@wu-wien.ac.at>
29 :    
30 :     * Wrote R documentation for some classes and methods.

33 :    
34 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
35 :     files. See the questionnaire data/Umfrage.csv for such an example.
36 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
37 : feinerer 22
38 : feinerer 21 * Changed class interfaces in various files. Weighting of the text
39 :     matrix is now possible.
40 :    
41 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
42 :    
43 :     * R/textdoccol.R: One can build term-document matrices if
44 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
45 :     document collection with it.
46 :    
47 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
48 :    
49 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
50 :    
51 :     * R/textdoccol.R: We now can read in a whole XML file with several
52 :     news items.
53 :    
54 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
55 :    
56 :     * R/textdoccol.R: Set up an S4 class for a collection of text
57 :     documents. A first attempt to read in XML input (like the RCV1
58 :     set) was made.
59 :    
60 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
61 :     some accessor functions.
62 :    
63 :     * data/newsitem.xml: Added this XML file for testing purposes. It
64 :     contains a single news item from the Reuters Corpus Volume 1
65 :     (RCV1) XML set.
66 :    
67 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
68 :    
69 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
70 :     textmatrix as k-means clustering provided by R (kmeans) now works on
71 :     this textmatrix. The result is a k-means text clustering with a
72 :     similarity measure based upon word frequences.
73 :    
74 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
75 :    
76 :     * R/textmatrix.R: Adapted the preprocessing code from the R
77 :     package "lsa" written by Fridolin Wild to build a document text matrix.
78 :    
79 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
80 :    
81 :     * Set up the R Text Mining Package infrastructure.
