随着网络的快速发展,人们对搜索引擎的依赖越来越强。传统搜索引擎仅基于关键字,而问答系统能够快速、准确地获取用户所需信息,是新一代搜索引擎。问答系统允许用户使用自然语言提问,能够准确返回用户所需答案。问答系统一般由问题理解、信息检索、答案抽取三部分组成。本文介绍了问题理解中的问题类型分类技术,并给出了具体实现。 相似文献

《搜神记·女化蚕》将一位“背信弃义”的女子如何化身为蚕,生生世世遭受蜕皮之苦、吐丝之累的前因后果娓娓道来。作为“蚕神”的原型,故事的女主人公已成一道独特风景线,其形象以及命运背后可能已非全然一种纯粹的原始意象,有必要从历史文化、社会演进、风俗价值观等的视野背景下重新观照《搜神记·女化蚕》背后潜藏的诸多复杂的时代价值观演进的痕迹和意蕴。 相似文献

互联网上信息资源相当丰富,存在于各个分散的服务器上。不同的人群对信息有着各自不同的需求,导致了各种各样搜索工具和技术的产生。人们对信息获取方式便捷化的要求促使了普适计算技术的发展,普适计算设备的研发蓬勃发展,日新月异。在智能手机、电子书、PDA这些普适设备上,由于处理能力不足、带宽窄、存储空间小、网络资费高,手机屏幕小等因素,现有的搜索技术不能只是简单地移植过来。提出了一种基于普适计算的检索模型,它支持全文搜索和协同过滤技术,立足于用户设备,提供给用户高效、精确、低成本的个性化搜索结果。 相似文献

One function of a call number is to organize the library collection to promote browsability either on the shelf or in an online catalog. This study, based on research done at the Ohio State University Libraries, examines the impact on library collection organization if call numbers are not changed to fit into the shelf list sequence. The browsability of items were tracked by assessing how many screens away titles appear from like items in the online public access catalog, if call numbers by a bibliographic utility were not changed. The study assesses whether not reviewing the call numbers affects patrons’ ability to find the items. 相似文献

Previous research suggests that individual nonverbal cues and cue complexes communicate multiple relational messages simultaneously. This work examines the contention that nonverbal percepts may predict relational message interpretations in romantic relationships. Results provide support for the hypothesis that nonverbal cues indicative of greater involvement, pleasantness, and expressiveness connote messages of intimacy. Specifically, the current study reveals that perceptions of intimacy and composure are associated with greater vocalic involvement. Interpretations are provided in line with the social meanings model. 相似文献

This article presents part of phase 2 of a research project funded by the NSF-National Science Digital Library Project, which observed how academic users interact with the ScienceDirect information retrieval system for simulated class-related assignments. The ultimate goal of the project is twofold: (1) to find ways to improve science and engineering students’ use of science e-journal systems; (2) to develop methods to measure user interaction behaviors. Process-tracing technique recorded participants’ processes and interaction behaviors that are measurable; think-aloud protocol captured participants’ affective and cognitive verbalizations; pre- and post-search questionnaires solicited demographic information, prior experience with the system, and comments. We explored possible relationships between affective feelings and cognitive behaviors. During search interactions both feelings and thoughts occurred frequently. Positive feelings were more common and were associated more often with thoughts about results. Negative feelings were associated more often with thoughts related to the system, search strategy, and task. Learning styles are also examined as a factor influencing behavior. Engineering graduate students with an assimilating learning style searched longer and paused less than those with a converging learning style. Further exploration of learning styles is suggested. 相似文献
