425 : feinerer 25 2005-11-30 Ingo Feinerer <h0125130@wu-wien.ac.at>
426 :    
427 :     * Wrote R documentation for some classes and methods.

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

439 :    
440 :     * R/textdoccol.R: One can build term-document matrices if
441 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
442 :     document collection with it.
443 :    
444 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
445 :    
446 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
447 :    
448 :     * R/textdoccol.R: We now can read in a whole XML file with several
449 :     news items.
450 :    
451 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
452 :    
453 :     * R/textdoccol.R: Set up an S4 class for a collection of text
454 :     documents. A first attempt to read in XML input (like the RCV1
455 :     set) was made.
456 :    
457 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
458 :     some accessor functions.
459 :    
460 :     * data/newsitem.xml: Added this XML file for testing purposes. It
461 :     contains a single news item from the Reuters Corpus Volume 1
462 :     (RCV1) XML set.

464 : feinerer 16 2005-10-07 Ingo Feinerer <h0125130@wu-wien.ac.at>
465 :    
466 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
467 :     textmatrix as k-means clustering provided by R (kmeans) now works on
468 :     this textmatrix. The result is a k-means text clustering with a
469 :     similarity measure based upon word frequences.

472 :    
473 :     * R/textmatrix.R: Adapted the preprocessing code from the R
474 :     package "lsa" written by Fridolin Wild to build a document text matrix.
475 :    
476 :     2005-10-02 Ingo Feinerer <h0125130@wu-wien.ac.at>
477 :    
478 :     * Set up the R Text Mining Package infrastructure.
