459 : feinerer 23 We are now able to import files in Reuters-21578 XML format.
460 : feinerer 22
461 : feinerer 21 * Changed class interfaces in various files. Weighting of the text
462 :     matrix is now possible.

465 :    
466 :     * R/textdoccol.R: One can build term-document matrices if
467 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
468 :     document collection with it.
469 :    
470 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
471 :    
472 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>

478 :    
479 :     * R/textdoccol.R: Set up an S4 class for a collection of text
480 :     documents. A first attempt to read in XML input (like the RCV1
481 :     set) was made.
482 :    
483 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
484 :     some accessor functions.
485 :    
486 :     * data/newsitem.xml: Added this XML file for testing purposes. It
487 :     contains a single news item from the Reuters Corpus Volume 1

491 :    
492 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
493 :     textmatrix as k-means clustering provided by R (kmeans) now works on
494 :     this textmatrix. The result is a k-means text clustering with a
495 :     similarity measure based upon word frequences.
