摘要
[目的/意义]旨在为案例检索方法的应用提供参考。[方法/过程]以Web of Science、CNKI数据库为数据来源,对国内外案例检索的相关文献进行归纳总结,分析其研究现状和研究热点。[结果/结论]案例检索研究可分为两类:一是理论研究,即案例检索思想与方法的论证;二是应用研究,即案例检索的改进,主要有相似度计算、沼泽现象处理、案例特征项的权值确定和属性值确定,以及属性缺失处理办法4个方面。
[Purpose/signiticance]The paper is to provide reference for application of case retrieval method. [Method/process] The paper takes Web of Science and CNKI databases as data source, summarizes case retrieval pertinent documents at home and abroad to analyze status quo and hotspots of the research. [Result/conclusion]Research of case retrieval can be divided into two cate-gories： one is theoretical research, which is demonstration of ideas and methods of case retrieval; the other is applied research, which is improvement of case retrieval, including 4 aspects of similarity computing, marsh phenomenon handling, determination of case charac- teristics weights and attribute value, and handling method of attribute missing.
