Rubryx is a software application of pattern classification of web sites. It allows classifying a large bulk of specialized textual information and generating web-catalogs, electronic libraries, reference systems on account of expert information and full-text analysis.
The aim of the program is to classify the documents most efficiently. For a successful solution of the task, an accurate selection of the class and threshold value of index K is required. The classes should be selected so that their intersection is minimized and the most bulk of documents is covered. Index K should be chosen so that odd documents are not included into the class (K value is too small) and suitable documents are not sorted away (K value is too big). A number of preliminary classifications may be required.
For preliminary classifications, make approx 1 per cent sample of the general bulk of documents. For example, for 100 thousand web sites to classify, 1 sites is enough for preliminary experiments. On the one hand, 1 sites is a representative sample, on the other hand, classification of such a sample on up-to-date computers will take a few moments.
During classification a part of documents can be excluded from all classes. These documents should be carefully studied. It is possible that new classes should be added to the list. Part of the residual documents may not suit for the generated catalog. Including of a large amount of the same documents into different classes means that the subject matter of the catalog has been poorly divided into classes.
Having obtained good results in sample classification, the whole bulk of documents can be classified. Consequently, you get a number of web sites of qualitative information corresponding to the number of classes.
