| Abstract: |
| Indexing and searching mechanism based mainly upon semantic attributes of documents has been showing certain limitations. The function of the non topical attributes and their implication to information retrieval and system design are not yet fully explored. By summarizing the non-topical characteristics of documents and by analyzing them in light of information needs, information seeking and use studies, the author attempts to explore their potentialities to information retrieval and information system design. Based on some non-topical attributes, a system, NSIRS, was developed and evaluated in order to test the ideas brought forward in this article. Finally, the non-topical features embedded in some well-known information retrieval systems are discussed as well. 4 figs. 4 tabs. 24 refs. |
| 中文摘要: |
| 主题检索一直是信息检索系统也是信息检索研究的重点，但文献的非主题特征的研究与利用没有受到足够的重视。文献的非主题特征指与文献相关，但与其主题内容或语义没有直接或必然联系的特征。笔者尝试较系统地归纳文献的非主题特征，并基于信息需求研究、信息查找与利用行为研究的有关理论，分析非主题特征对于信息检索理论与实践的意义，并通过基于非主题特征的网络中文学术文献识别系统（NSIRS）的设计与评价，验证其可行性与效果，分析了当前一些信息检索系统的非主题检索功能与特色。图4。表4。参考文献24。 |
