Bag-Of-Words To Tile-Vizualization

The utility performs calculation of the Tile-Vizualization procedure and outputs the result into the XML file ("-o"). With the parameter "-docs" the number of considered documents is determined (value "-1" means all documents"). The parameter "-clusts" determines the final  number of clusters. The parameter "-rseed" determines the value of random-number-generator seed, where value 0 means nondeterministic value. The parameter "-mncdocs" determines maximal number of documents per leaf cluster. The parameter "-ctrials" determines the number of different runs/trials of K-Means algorithm in a search for the best solution. The parameter "-ceps" determines convergence epsilon value which influences the stopping criterium for the K-Means algorithm. The parameter "-cutww" determines the percentage of the sum of the weights for the best words in the centroids which appear in the textual output file. The parameter "-mnwfq" determines the minimal document-frequency of the words which are used for the document representation. The parameter "-propwgt" determines the mode of propagating the word-weights when executing the top-down 2-means clustering algorithm. The "-topwords" parameter determines the number of best words written in the description of each centroid.

Example:
Bow2VizTile.exe -i:Reuters21578.Bow -docs:1000

Calculates hierarchical clustering on 1000 documents ("-docs") from Reuters21578 into 10 clusters ("-clusts"), transforms clusters into  rectangular tiling outputs the structure of tiles in the XML  file with the default name "VizTile.Xml" ("-o").
