  abstract      = {In previous research, a TFxIDF vector representation of legal documents was the basis for structuring and labelling a collection of legal documents. Extensive experiments with three text corpora of European law of about 580 documents in three languages have shown, that binary or weighted vector representation may not be sufficient. Even quite successful approaches of similarity computation have problems in identifying the best context of classification. This paper deals with a new approach. The vector representation is modified using a simple ontology of the domain. The adaptation of the vector is done using the newly developed Data Enrichment feature of the SOM/KONTERM library.  This approach was evaluated with a small text corpus of 253 documents of cyberspace law. The improvement was significant in the quality of the clusters but also the labels. }
