Natural Language Processing (NLP) techniques have been successfully used to automatically extract information from unstructured text through a detailed analysis of their content, often to satisfy particular information needs. In this paper, an automatic concept map construction technique, Fuzzy Association Concept Mapping (FACM), is proposed for the conversion of abstracted short texts into concept maps. The approach consists of a linguistic module and a recommendation module. The linguistic module is a text mining method that does not require the use to have any prior knowledge about using NLP techniques. It incorporates rule-based reasoning (RBR) and case based reasoning (CBR) for anaphoric resolution. It aims at extracting the propositions in text so as to construct a concept map automatically. The recommendation module is arrived at by adopting fuzzy set theories. It is an interactive process which provides suggestions of propositions for further human refinement of the automatically generated concept maps. The suggested propositions are relationships among the concepts which are not explicitly found in the paragraphs. This technique helps to stimulate individual reflection and generate new knowledge. Evaluation was carried out by using the Science Citation Index (SCI) abstract database and CNET News as test data, which are well known databases and the quality of the text is assured. Experimental results show that the automatically generated concept maps conform to the outputs generated manually by domain experts, since the degree of difference between them is proportionally small. The method provides users with the ability to convert scientific and short texts into a structured format which can be easily processed by computer. Moreover, it provides knowledge workers with extra time to re-think their written text and to view their knowledge from another angle. 相似文献

网络知识组织系统(NKOS)可用于网络信息资源的组织和检索,弥补目前基于文本匹配的组织检索系统的缺陷。简单知识组织系统(SKOS)是W3C于2004年发布的新的网络知识组织系统表示语言,尽管目前还处于不成熟的发展阶段,但它的简单易用、适用范围广等优越性已经引起广泛注意;同样,SKOS作为W3C推荐的受控词表的表示标准,在促进受控词表的实际应用等方面有着非同寻常的意义。该文在NKOS的背景下详细介绍SKOS标准,并简单分析SKOS与其他知识组织系统表示语言的差异,然后举例部分SKOS现有应用,最后对SKOS及NKOS的应用加以展望。 相似文献

关于新闻定义的讨论一直是学术界关注的问题,针对较有影响的陆定一、范长江、宁树藩三位学术前辈关于新闻定义的观点进行了再讨论,分析其中值得借鉴与尚有欠缺之处,并提出了新闻定义中的受众本位观问题和强调“过程性”的定义思维,最终在有理有据的分析基础上给出定义:“新闻是及时公开报道的新近发生或发现的受众应知而未知或欲知而未知的信息”。 相似文献

中国县域文化与居民性格研究既是本土心理学的课题,也是跨文化心理学的课题,更是文化心理学、社会心理学的课题,在本土心理学和文化心理学尚未成熟的背景下,使用跨文化心理学概念框架是一个有益的选择。采用田野工作法、文献资料法、调查访谈法、经验总结法、逻辑推理法等方法,使用背景变量、过程变量、心理变量的实验心理学概念,区分生态学背景变量、社会政治背景变量;生物适应变量(包括包括生态影响、生物传递)、文化适应变量(文化传递、社会化和濡化);可见行为变量、推论行为变量的心理变量等概念。观察、分析、综合、抽象、概括了张掖甘州文化类型与居民性格特质及其关系,进而进行了县域文化与性格研究的展望。 相似文献

An academic librarian, especially one who works primarily in a research consultation capacity, often encounters individuals who are seeking in-depth help with research projects that they struggle to explain. The number of concepts, interdependencies and assumptions involved in research projects today can make them difficult to define and discuss with other people. The multidisciplinary nature and globalization of many areas of research is forcing researchers to not only discuss, but to collaborate with many others from different academic backgrounds and disparate physical locations. Many researchers struggle with project paralysis at various points along the way as they attempt to manage both the myriad of details and the bigger picture relationships and implications of their project.A number of visual tools including concept mappers and mind mappers are well suited to help advanced students, faculty, researchers and librarians to organize the ideas and knowledge throughout the various stages of complex research, from envisioning an idea to the early stages of actively researching and documenting research findings. This paper will discuss the potential uses of visual mapping tools and review the current state of academic literature surrounding the topics of mind mapping and concept mapping. 相似文献
