本文针对国际联机检索系统中的文献型数据库,从文献逻辑检索的基本原理出发,以DIALOG系统为参照,总结推导出检索课题规范性分析法则及在此基础上的检索策略优化模型——AB模型。同时,还给出了本模型在操作执行过程中的组配机制。利用本模型对检索课题进行分析检索,可以提高检索效率/费用比及检索一致性,避免由于检索者自身检索素质的差异给检索结果带来的消极影响。
In this paper, aiming at the document type database in international online search system, starting from the basic principle of document logical retrieval and referring to DIALOG system, this paper summarizes the normative analysis rules of search questions and the retrieval strategy optimization model based on it --AB model . At the same time, the mechanism of assembly of this model in operation and execution is given. Using this model to search and retrieve retrieval questions can improve retrieval efficiency / cost ratio and consistency of retrieval, and avoid the negative impact on the retrieval results caused by the difference of searchers’ retrieval quality.
