Abstract: Approximate matching is a type of matching whose pattern includes ap proximate informations and it is one of the main search areas currently related to string matching. Horspool algorithm is one of the most classic algorithms rel ated to accurate matching while it can not fulfill approximate matching.This pap er transforms pattern into binary lists and improves Horspool algorithm in order to fulfill both accurate matching and approximate matching.

摘要： 匹配模式中存在模糊信息的匹配形式称为模糊匹配，它是目前字符串匹配的重 要研究方向。Horspool算法是精确匹配的经典算法，但不能实现模糊匹配。该文将要求匹配 的模式转化为相应的二进制数序列，在Horspool算法基础上扩大其功能，使其能够实现模糊 匹配，且不影响其精确匹配的功能。
