Research dynamics: Measuring the continuity and popularity of research topics

Dynamic development is an intrinsic characteristic of research topics. To study this, this paper proposes two sets of topic attributes to examine topic dynamic characteristics: topic continuity and topic popularity. Topic continuity comprises six attributes: steady, concentrating, diluting, sporadic, transforming, and emerging topics; topic popularity comprises three attributes: rising, declining, and fluctuating topics. These attributes are applied to a data set on library and information science publications during the past 11 years (2001–2011). Results show that topics on “web information retrieval”, “citation and bibliometrics”, “system and technology”, and “health science” have the highest average popularity; topics on “h-index”, “online communities”, “data preservation”, “social media”, and “web analysis” are increasingly becoming popular in library and information science.     

Feeling Caught: Adult Children's Experiences with Parental Infidelity

The purpose of this study was to understand what, if any, messages adult children recalled receiving from family members following the discovery of their parents’ infidelity that either discouraged or encouraged feeling caught. Thirty-eight individuals were interviewed. Findings suggested that adult children received messages about parental conflict being between their parents, no one being the good/bad guy, and speaking favorably about change, all of which discouraged feeling caught. Messages that encouraged feeling caught involved urging the child to uncover information, serve as a mediator, and field other family members’ opinions. These findings are compared to previous research.     

Health-related information seeking: Is it worth it?

In spite of often compelling reasons for why people should seek information, they persistently engage in lower levels of it than might be expected, at times seeking no information at all. The idealized model reflecting dogged persistence, pursuing rational search strategies, until a high-quality answer is found is often assumed in the design of information systems. However, many people confronted with health problems engage in avoidance and denial, making a health care system dependent on proactivity problematic. This essay explores six conditions, the idealized model, avoidance, bewilderment, serendipity, ignorance is bliss, and indolence, that arise from low and high effort strategies when typed by good, contingent, and bad health outcomes. Since a substantial proportion of the population does not act in accordance with our assumptions, it may be time for policy makers, system designers and researchers to revisit their approaches to facilitating health-related information seeking.     

Communication apprehension as a determinant of avoidance,withdrawal and performance anxiety

Although communication apprehension (CA) is often presented as having a major impact on communication related behavior, the extant literature provides neither strong nor direct support for such claims. In the present research (1) behavior was viewed as a single index of disjunctively connected response options including avoidance, withdrawal and anxiety and (2) CA was viewed as a categorical rather than a continuous variable. Results of two separate studies provide direct evidence suggesting that CAs avoid communication if possible and report considerable anxiety when forced to communicate.     

主题地图约束的合法性验证*

主题地图作为异构信息检索的重要手段之一，在以分类目录为目的的文件存档和以概念化导航为目的的Web浏览中得到广泛应用。为了保证作为其基础的下层语义网络的完备性和健壮性，验证主题地图在语法和语义上的合法性非常重要。为此，提出了主题地图模式及约束语言规范，研究了Schema约束和上下文语义约束，并建立了与之相配套的主题地图语义验证器，实现了对于主题地图约束的合法性验证。     

浅谈多元化毕业设计对大学生创新能力的培养

针对大学生创新能力培养的毕业设计环节,构建一个毕业设计的多元化选题平台,加强多元化创新实践基地建设,采用多元化毕业设计指导模式。以此为基础,进一步探讨大学生创新意识、创新思维和创新能力的培养方式。     

2009年以来我国网络流行语的传播机制研究

选取近三年来一些最能代表社会舆论、简短精炼的网络流行语进行分析,以求可以深入挖掘网络流行语的形成与流行机制。通过分析发现,网络流行语不拘于传统媒体的规范用语要求,契合了网络这一媒介的传播特性,它在内容上的时代感、讽刺性和宣泄性,形式上的灵活性和创造性,使其突破了网络这个单一的传播渠道,成为包括传统媒体在内的全媒体的热捧。这些网络流行语在一定程度上折射并反映出社会现实,是由社会现实所引发的年轻群体对话语权的追求,有些网络流行语的广泛传播,更是促进了新闻事件的解决,取得了意想不到的效果。然而,盲目的跟风和复制只会削弱其传播效果,也有很多网络流行语出于商业利益的考虑,大有炒作之疑,急需规范这些网络行为。     

Web主题信息采集中信息主题的识别

主要介绍了我们设计的Web主题信息采集系统的一项核心工作——Web信息主题的识别，主题识别算法从构造专业性较强的主题词典着手，充分分析和考虑Web网页文本的特点，从而大大提高了主题信息采集的效率和精度，该算法同样适用于其他领域的主题信息识别。     

基于语义爬虫的商品信息主题采集研究*

结合网页主题链接分析和网页主题内容语义分析,提出一个以主题爬虫实现采集商品信息的方法。在爬行过程中通过对本体的统计学习,使主题本体参照物不断得到优化。实验结果表明,该方法较其他传统爬行算法更有效,并能防止主题漂移的发生,带来较高的主题收获率。
