Abstract
Compressed pattern matching is one of the most active top- ics in string matching. The goal is to find all occurrences of
a pattern in a compressed text without decompression. Various algorithms have been proposed depending on underlying compression
methods in the last decade. Although some algorithms for multipattern searching on compressed text were also presented very
recently, all of them are only for Lempel-Ziv family compressions. In this paper we propose two types of multipattern matching
algorithms on collage system, which simulate the AC algorithm and a multipattern version of the BM algorithm, the most important
algorithms for searching in uncompressed files. Collage system is a formal framework which is suitable to capture the essence
of compressed pattern matching according to various dictionary based compressions. That is, we provide the model of multipattern
matching algorithm for any compression method covered by the framework.
