Webometric research with the Bing Search API 2.0

In May 2011 the Bing Search API 2.0 had become the only major international web search engine data source available for automatic offline processing for webometric research. This article describes its key features, contrasting them with previous web search data sources, and discussing implications for webometric research. Overall, it seems that large-scale quantitative web research is possible with the Bing Search API 2.0, including query splitting, but that legal issues require the redesign of webometric software to ensure that all results obtained from Bing are displayed directly to the user.     

固定背景下人脸图像的特征提取

对于复杂人脸模式、脸部特征的提取,是人脸自动识别技术的关键,本文对固定背景下人脸图像特征的定位和提取算法进行了分析.文中首先对彩色图像背景进行分割,得到二值化图像;然后采用边界搜索方法确定人脸外接矩形;最后在色度空间中,结合SUSAN角点检测方法,实现人眼、嘴角定位,完成了人脸图像特征的提取和识别.实验证明,该算法在降低运算区域的同时,降低了运算复杂度和其他干扰因素,并且在速度、效率、准确性方面均有良好的性能.

“Books.Google.RU”—Google's Mass Digitization of Russian‐Language Books

ABSTRACT. Google is pursuing “mass digitization” of Russian books as part of its efforts that now involve more than a dozen partners, although so far there is no separate Russian‐language search interface. How easy is it to find materials in books.google.com that are in Russian? What do users need to know to maximize their results?     

Government Information on the Web

Summary

Government information is abundant on the World Wide Web, but finding that information is often difficult. The usual routine of utilizing search engines or directories does not work well, unless an individual is interested in a specific government agency. Instead, the savvy librarian will be well advised to check the prominent journals and newspapers for announcements of new sites and utilize the homepage of the Library of Congress. With some education and experience, a user can quickly find information using the Library of Congress' homepage, the Librarian's Index to the Internet, and Beaucoup.     

Metadata Dreaming

ABSTRACT

The author presents the state of metadata schemes today and discusses the idea of a “third way” between free-text searching and full cataloguing. He concludes that there is no such compromise and suggests that metadata schemes will have to incorporate controlled vocabularies and detailed designators if they are to progress, thus leading to a confluence that will be, in essence, a new form of traditional cataloguing.     

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.

Are Information Seekers and Users Among the General Public at a Crossroads?

Abstract

Presently, eating disorders affect millions of people. Today, the media and the Internet are major publishing channels for consumer health information. Much research has found that the media may offer insufficient information on eating disorders. This research examines the quantity of adult consumer health publications on eating disorders in magazine articles and on the Internet in 1998 and investigates the effectiveness of Internet search engines. The results indicate that the resources found in popular magazines and on the Internet are not adequate, and that the Internet search engines are not effective in searching for information.     

Google Book Search and Metadata

This article summarizes published documents on metadata provided by Google for books scanned as part of the Google Book Search (GBS) project and provides suggestions for improvement. The faulty, misleading, and confusing metadata in current Google records can pose potentially serious problems for users of GBS. Google admits that it took data, which proved to be inaccurate, from many sources and is attempting to correct errors. Some argue that metadata is not needed with keyword searching; but optical character recognition (OCR) errors, synonym control, and materials in foreign languages make reliable metadata a requirement for academic researchers. The authors recommend that users should be able to submit error reports to Google to correct faulty metadata.
