1217 :    
1218 : feinerer 799 * Updated documentation
1219 : feinerer 26
1220 : feinerer 25 2005-11-30 Ingo Feinerer <h0125130@wu-wien.ac.at>
1221 :    
1222 : feinerer 799 * Wrote R documentation for some classes and methods.
1223 : feinerer 25
1224 : feinerer 21 2005-11-19 Ingo Feinerer <h0125130@wu-wien.ac.at>
1225 :    
1226 : feinerer 22 * R/textdoccol.R: Constructor of textdoccol allows import of CSV
1227 :     files. See the questionnaire data/Umfrage.csv for such an example.
1228 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
1229 : feinerer 22
1230 : feinerer 799 * Changed class interfaces in various files. Weighting of the text
1231 : feinerer 21 matrix is now possible.

1234 :    
1235 :     * R/textdoccol.R: One can build term-document matrices if
1236 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
1237 :     document collection with it.
1238 :    
1239 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
1240 :    
1241 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
1242 :    
1243 :     * R/textdoccol.R: We now can read in a whole XML file with several
1244 :     news items.
1245 :    
1246 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
1247 :    
1248 :     * R/textdoccol.R: Set up an S4 class for a collection of text
1249 :     documents. A first attempt to read in XML input (like the RCV1
1250 :     set) was made.
1251 :    
1252 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
1253 :     some accessor functions.
1254 :    
1255 :     * data/newsitem.xml: Added this XML file for testing purposes. It
1256 :     contains a single news item from the Reuters Corpus Volume 1
1257 :     (RCV1) XML set.

1259 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
1260 :    
1261 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
1262 :     textmatrix as k-means clustering provided by R (kmeans) now works on
1263 :     this textmatrix. The result is a k-means text clustering with a
1264 :     similarity measure based upon word frequences.
1265 :    
1266 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
1267 :    
1268 :     * R/textmatrix.R: Adapted the preprocessing code from the R
1269 :     package "lsa" written by Fridolin Wild to build a document text matrix.
1270 :    
1271 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
1272 :
