| Abstract(in English) | In the present paper we propose a new method for clustering text data by using the Normalized Compression Distance and Zero-Suppressed BDDs. The Normalized Compression Distance can be considered as an approximation of the Normalized Information Distance which is defined by using Kolmogorov complexity. Standard string compressors such as gzip, bzip2 have been previously used to compute the Normalized Compression Distance. In contrast, we propose to use the ZBDD representation of item sets as a compressor for the item sets. We conducted experiments for clustering by using our methods. The results obtained show the usefulness of this approach. |
