428 :    
429 : feinerer 29 * Wrote a script for the ModLewis Split for the Reuters-21578 XML
430 :     data set.
431 :    
432 : feinerer 28 * Finished documentation and reordered directory structure. Now "R
433 :     CMD check textmin" works without errors.

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

458 :    
459 :     * R/textdoccol.R: One can build term-document matrices if
460 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
461 :     document collection with it.
462 :    
463 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
464 :    
465 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
466 :    
467 :     * R/textdoccol.R: We now can read in a whole XML file with several
468 :     news items.
469 :

471 :    
472 :     * R/textdoccol.R: Set up an S4 class for a collection of text
473 :     documents. A first attempt to read in XML input (like the RCV1
474 :     set) was made.
475 :    
476 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
477 :     some accessor functions.
478 :    
479 :     * data/newsitem.xml: Added this XML file for testing purposes. It
480 :     contains a single news item from the Reuters Corpus Volume 1
481 :     (RCV1) XML set.

484 :    
485 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
486 :     textmatrix as k-means clustering provided by R (kmeans) now works on
487 :     this textmatrix. The result is a k-means text clustering with a
488 :     similarity measure based upon word frequences.

490 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
491 :    
492 :     * R/textmatrix.R: Adapted the preprocessing code from the R
493 :     package "lsa" written by Fridolin Wild to build a document text matrix.
