A framework of context-sensitive grammar transform is proposed. A greedy compression algorithm with the transform model is presented as well as a Knuth-Morris-Pratt (KMP)-type compressed pattern matching (CPM) algorithm. The compression performance is a match for gzip and Re-Pair. The search speed of our CPM algorithm is almost twice faster than the KMP type CPM algorithm on Byte-Pair-Encoding by Shibata et al. (2000), and in the case of short patterns, faster than the Boyer-Moore-Horspool algorithm with the stopper encoding by Rautio et al. (2002), which is regarded as one of the best combinations that allows a practically fast search.
