RFID: The Next Serious Threat to Privacy

Radio Frequency Identification, or RFID, is a technology which has been receiving considerable attention as of late. It is a fairly simple technology involving radio wave communication between a microchip and an electronic reader, in which an identification number stored on the chip is transmitted and processed; it can frequently be found in inventory tracking and access control systems. In this paper, we examine the current uses of RFID, as well as identifying potential future uses of the technology, including item-level tagging, human implants and RFID-chipped passports, while discussing the impacts that each of these uses could potentially have on personal privacy. Possible guidelines for RFID’s use, including Fair Information Principles and the RFID Bill of Rights are then presented, as well as technological solutions to personal privacy problems, such as tag killing and blocker tags, as well as simple aluminum foil shields for passports. It is then claimed, though, that guidelines and technological solutions will be ineffective for privacy protection, and that legislation will be necessary to guard against the threats posed by the RFID. Finally, we present what we believe to be the most important legislative points that must be addressed.

基于LSA的社会化标注系统标签语义检索研究

在分析社会化标注系统标签检索研究现状基础上,针对传统方法可计算性不高、完备性不够、无法分辨自然语言的语义模糊性等不足,提出基于潜在语义分析的社会化标注系统标签语义检索模型,改进标签-资源矩阵权重计算算法,完善社会化标注系统的语义标注方法。并以delicious系统为例,抓取数据进行验证分析,通过对比,证明提出的模型和改进的算法能显著提高标签检索效率。     

社会化标注环境下的标签共现谱聚类方法

在分析标签共现的基础上, 提出一种基于共现的标签谱聚类方法, 该方法直接利用标签的共现关系来测度标签的相关性, 能够避免将标签表示成向量空间模型时所带来的高维稀疏等问题.在衡量标签的共现相似性时, 设计一种综合的方法, 并给出标签综合共现相似度的计算公式.与传统的单一利用标签的个体共现来衡量其相似性相比, 综合的方法同时考虑标签的个体共现相似性和标签的群体共现相似性, 能够更加精确地刻画标签的共现相似度.实验结果表明, 基于综合共现相似度的标签共现谱聚类方法具有较好的效果.     

OPACs,Users, and Readers’ Advisory: Exploring the Implications of User-Generated Content for Readers’ Advisory in Canadian Public Libraries

This article examines the contribution of social discovery platforms and user-generated content (UGC) on readers’ advisory (RA) services in Canadian public libraries. Grounded Theory was used to conduct a content analysis of library-assigned subject headings and UGC of 22 adult fiction titles in 43 Canadian public libraries that use BiblioCommons, SirsiDynix, and Encore social discovery platforms. Findings indicate that UGC complements the MARC bibliographic record as it provides insight into the subject of a work, its protagonists, and the effect the book has on readers. User-generated reviews provide a rich data set that clearly connects to known RA access points.     

社会标注在卫生社交网络中的应用

随着Web2．0技术的发展,社会标注作为网络资源组织的重要方式,已经广泛应用于各种类型的网站。通过深入研究社会标注在卫生社交网络中的应用和存在的不足,提出了建立社会化登陆模式、构建标签库、建立标签自动分类系统、实现个性化推荐机制、进行标签语义分析、设置用户权限等促进卫生社交网络朝着更好方向发展的建议。

Adaptive Filtering of Newswire Stories using Two-Level Clustering

Adaptive filtering of news is an area of information retrieval gaining substantial interest as services become more available on the Internet. This paper reports on a number of experiments involving a two-level clustering approach using a variety of techniques including threshold adaptation, topic vocabulary adaptation and both noun phrase and named entity adaptation. Our goal in this exploratory research is to empirically compare alternative configurations of our filtering approach that will allow us to better understand the relative value of the component subsystems.     

社会标签的规范性研究——图书标注

分析图书标注的发展以及中英文图书标注系统,比较社会标注与主题标引的异同,综述国内外图书标签规范性研究的现状,并以图书情报领域为例,就中英文用户的图书标注与图书馆的图书编目进行对比实验,实验显示出社会标签与受控的主题词的重合率不高这一问题.在详细分析实验结果的基础上,提出对图书标注进行规范控制的若干建议.
