| 摘 要： | 以汉语题名目录的模糊检索为例，对机读目录目前存在的模糊检索问题进行分析，提出一个基于集合运算的改进方案，通过细粒度拆分待检题名并将拆分所得的各元字符作为冗余待检题名逐一执行检索，再对全部检索结果执行有关集合运算实施聚合，以得到尽可能接近检索者本意的题名及其馆藏信息，增强机读目录的模糊检索深度，低成本优化现行检索系统。

| Abstract: | Taking fuzzy retrieval for Chinese title catalogue as an example,this paper analyses the fuzzy retrieval problem for MARC and proposes an improvement solution based on set operations.It splits the title for retrieval to metacharacters by fine-granularity and retrieves these metacharacters as redundant title for retrieval,then converges all retrieve results by set operations and returns.The improvement solution can enhance the depth to fuzzy retrieval for MARC and optimize present retrieval system with low-cost. |
