摘要

根据各种基于字典的压缩,提出了一个适合捕捉压缩模式匹配本质的通用框架,并提出了该框架的压缩模式匹配算法。目标是在不解压缩的情况下找到文本中模式的所有出现,这是字符串匹配中最活跃的主题之一。我们的框架包括这样的压缩方法,如Lempel-Ziv族,(LZ77, LZSS, LZ78, LZW) (J. Ziv和A. Lempel, 1978),字节对编码和基于静态字典的方法。技术上,我们的模式匹配算法扩展了A. Amir等人(1996)提出的LZW压缩文本的模式匹配算法。

A unifying framework for compressed pattern matching
We introduce a general framework which is suitable to capture an essence of compressed pattern matching according to various dictionary based compressions, and propose a compressed pattern matching algorithm for the framework. The goal is to find all occurrences of a pattern in a text without decompression, which is one of the most active topics in string matching. Our framework includes such compression methods as Lempel-Ziv family, (LZ77, LZSS, LZ78, LZW) (J. Ziv and A. Lempel, 1978), byte-pair encoding, and the static dictionary based method. Technically, our pattern matching algorithm extends that for LZW compressed text presented by A. Amir et al. (1996).
