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。
Through comparative study of knowledge change between exploratory and non-thematic search, this paper tests the influence of non-thematic factors on exploratory information retrieval by using the experimental and interview methods. The results show that, through the concept map and screen record analysis, non-thematic search leads to more obvious change of the knowledge of the searcher and higher retrieval rate and the retrieval satisfaction of the searcher within the limited retrieval time than the thematic search.
