摘要
文章通过对探索性主题检索和非主题检索的知识变化对比研究,利用实验法和访谈法检验了非主题因素对探索性信息检索的影响。结果发现通过概念图和屏幕记录分析,在有限的检索时间内,与主题检索相比,非主题检索引起检索者的知识变化更为明显,检准率和检索者的检索满意度也较高。
Based on the comparative study of exploratory subject retrieval and non-subject retrieval,this paper uses experimental method and interview method to verify the effect of non-subject factor on exploratory information retrieval. The result shows that based on the analysis of concept map and screen recorder,the non-subject retrieval causes more obvious knowledge changes than subject retrieval within limited time,which also obtains higher retrieval accuracy and retrieval satisfaction.
