| Popis | In this paper we present drapi, an algorithm for independent distributed mining of first-order frequent pattern. This system is based on RAP, an algorithm for finding maximal frequent patterns in first-order logic. drapi utilizes a modified data partitioning schema introduced by Savasere et al. and offers good performance and low communication overhead. We analyze the performance of the algorithm on four different tasks: Mutagenicity prediction - a standard ILP benchmark, information extraction from biological texts, context-sensitive spelling correction, and morphological disambiguation of Czech. The results of the analysis show that the algorithm can generate more patterns than the serial algorithm RAP in the same overall time. |
