419 :    
420 :     * R/aobjects.R: Changed package document structure to avoid class
421 :     dependency problems.
422 :    
423 : feinerer 28 2005-12-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
424 :    
425 : feinerer 29 * Wrote a script for the ModLewis Split for the Reuters-21578 XML
426 :     data set.
427 :    
428 : feinerer 28 * Finished documentation and reordered directory structure. Now "R
429 :     CMD check textmin" works without errors.

431 : feinerer 27 2005-12-04 Ingo Feinerer <h0125130@wu-wien.ac.at>
432 :    
433 :     * src/: Various splits can now be easily created for the
434 :     Reuters21578 data set.

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

453 : feinerer 20 2005-11-08 Ingo Feinerer <h0125130@wu-wien.ac.at>
454 :    
455 :     * R/textdoccol.R: One can build term-document matrices if
456 :     nessecary (with buildTDM(...)) and fill the field tdm from a text
457 :     document collection with it.
458 :    
459 :     * R/textmatrix.R: Wrote S4 class for term-document matrices.
460 :    
461 : feinerer 19 2005-11-06 Ingo Feinerer <h0125130@wu-wien.ac.at>
462 :    
463 :     * R/textdoccol.R: We now can read in a whole XML file with several
464 :     news items.
465 :    
466 : feinerer 17 2005-11-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
467 :    
468 :     * R/textdoccol.R: Set up an S4 class for a collection of text
469 :     documents. A first attempt to read in XML input (like the RCV1
470 :     set) was made.
471 :    
472 :     * R/textdocument.R: Set up an S4 class for text documents. Wrote
473 :     some accessor functions.
474 :    
475 :     * data/newsitem.xml: Added this XML file for testing purposes. It
476 :     contains a single news item from the Reuters Corpus Volume 1
477 :     (RCV1) XML set.

480 :    
481 :     * R/textmatrix.R (textmatrix): Removed the transpose of the original
482 :     textmatrix as k-means clustering provided by R (kmeans) now works on
483 :     this textmatrix. The result is a k-means text clustering with a
484 :     similarity measure based upon word frequences.

486 :     2005-10-05 Ingo Feinerer <h0125130@wu-wien.ac.at>
487 :    
488 :     * R/textmatrix.R: Adapted the preprocessing code from the R
489 :     package "lsa" written by Fridolin Wild to build a document text matrix.
