基于主题词表的OPAC检索提示

Retrieval Prompts based on OPAC Thesaurus

针对当前OPAC缺少检索提示而造成绩效不佳的现状,进行检索提示的需求、思路、设计及实现方法的研究。利用Ajax、JavaScript、Css和数据库相关技术对主题词进行采集、存储、查询及显示,通过分析书目主题词的数据特征及主题词表的数据结构、设计主题词数据采集与存储方案来构建主题词表,在此基础上实现主题词热门推荐、输入联想、拼写检查、查询扩展、英文释义与内文链接、主题检索的结果聚类与图书推荐等书目检索提示并评估应用效果,从而对用户的检索行为给出实时的、丰富的、科学的检索提示。

By means of Ajax, JavaScript, Css and database, we could collect, save, query and display subject words, as well as building the thesaurus by analyzing the characteristics of subject words, the data structure of thesaurus, and designing the plan of collecting and storing subject words. Then we could enable the functions of retrieval prompts such as the popular subjects recommendation, input suggestion, spelling check, query expansion, English explanation and internal text link as well as cluster results and books recommendation, providing the real-time, rich and scientific retrieval prompts for users.
