互联网“人肉搜索”初探

随着Internet技术的发展和普及。人肉搜索作为一种新的互联网搜索技术在网民中受到追捧。这是一种快速的交互式信息传播方式,拥有广泛的参与主体,具有虚拟平等性,其初衷是助人为乐、还原真相、除恶扬善。虽然人肉搜索切实帮助许多老百姓解决了生活中的问题,也惩罚了某些社会不良行为,然而在现有相关法律相对滞后的情况下,由于网络及人内搜索自身的特性,它也带来了侵犯隐私、网络群体暴力等问题。     

一种基于商标的图像搜索引擎方法

以商标的二值化图片作为商标的形状特征,待辨识图案经过一系列预处理过程(包括商标图案的分割和定,图片大小调整)之后,以点对点比对方式与作为模板的标准图片进行比较,通过得到最大相似程度的方式来进行商标图片分类。通过对实验结果进行分析,表明二值化图片作为商标图案的形状特征具有一定的有效性。     

柴油机机架双机器人焊接工作站离线编程技术

介绍了焊接机器人离线编程系统的组成,分析了路径规划的实用功能;搭建了双机器人工作站仿真场景,采用单点法,先在现场标定工作平台的实际位置,然后在仿真场景中进行校准;利用该仿真场景,离线编写了机架模拟件的双机器人焊接程序,然后下载程序到现场控制柜调试运行;将机架模拟件偏移放置后,自动运行整个焊接程序,进行了模拟件的双机器人多层多道焊接．实验结果表明,模拟件焊接后的焊道符合实际的焊缝位置,经离线编写的程序能够在实际环境中得到较好的廊用．     

面向业务平台原理及其在软件工程中的作用

为了解决业务应用系统软件工程中需求变更带来的系统研发滞后,以及业务人员同软件开发人员沟通带来的沟通偏差等问题,面向业务平台将业务应用系统分离为系统层和业务层。在业务层,业务人员使用业务设计器直接进行需求建模,系统层业务引擎负责执行业务模型。这样使系统适应变化能力增强,是随需应变的解决之道。     

Relational messages associated with nonverbal involvement,pleasantness, and expressiveness in romantic couples

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.     

Optimal Results: What Libraries Need to Know About Google and Search Engine Optimization

Search engine optimization, or the practice of designing a web site so that it rises to the top of the results page when users search for particular keywords or phrases, has become so prevalent on the modern web that it has a significant influence on Google search results. This article examines the techniques used by search engine optimization practitioners, the difference between “white hat” and “black hat” optimization tactics, and why it is important for library staff to understand these techniques and their impact on search engine results pages. It also looks at ways that library staff can help their users develop awareness of the factors that influence search results and how to better assess the quality and relevance of results listings.     

基于Flash3D技术的小学立体几何教学平台的设计与实现

空间观念的培养是小学数学课程的重要目标之一。当前的教学过程中缺少可以操作的可视化学习工具,难以满足立体几何的教学需求,根据这一问题设计并实现了小学立体几何教学平台。文章阐述了该平台的设计理念、主要功能和系统架构,引进了新兴的Flash3D技术,并对著名的Flash3D引擎——Alternativa3D的开发流程进行了详细介绍,基于该引擎对平台进行实现。平台具有逼真的三维场景、丰富的感性资源、友好的交互方式等特点,是新技术在教学中应用的一次有益尝试。     

分布式学术搜索引擎研制及其大数据应用

受“搜索引擎”流行的影响,目前大家已经习惯把图书情报领域使用的“情报检索系统”称之为“学术搜索引擎”。无论从技术层面上还是应用层面上,尽管二者有很大的共同点,但也有很大差异。传统的集中式的搜索引擎已经无法满足飞速发展的信息爆炸和普及化的海量需求用户,能够提供“云服务”的分布式搜索引擎已经成为必然。文章主要内容包括学术搜索引擎涉及的关键技术、分布式搜索引擎的架构,以及分布式搜索引擎在大数据领域的主要应用价值三个方面,最后给出了分布式搜索引擎RMSCIoud的典型应用介绍。     

An Exploration of Indexed and Non-Indexed Open Access Journals: Identifying Metadata Coding Variations

The intent of this investigation was to learn what factors may have contributed to low usage of a small set of reputable open access scholarly journals, as evidenced in graduate student reference lists. Inquiry into differences among open access sources referenced between 2005 and 2014 revealed that non-indexed journals were being used notably fewer times than their commercially indexed counterparts. A comparison of HTML source code between indexed and non-indexed journals illustrated that certain metadata and other coding features may have affected the visibility of non-indexed journal content. The study suggests to librarians the presence of less visible empirical literature on the web and to smaller, independent academic publishers, the need to apply better quality metadata and optimization strategies to their open access journal content.
