基于结构语义的Web页面中超链接的分类

超链接作为WWW 中的一种信息组织方式, 在W eb 信息服务中已占有重要的地位。但是由于超链接仅仅是为了实现文档的非线性组织而产生的, 因而超链接本身缺乏语义信息。因此, 首先对超链接从语义上进行分类具有重要的意义。本文首先介绍了以往对超链接类型定义和分类的研究工作, 然后通过分析W eb 页面类型及相互之间的关系提出了一个基于结构语义来划分超链接类型的方法, 并初步探讨了它在信息收集和查询等方面的应用。     

Taxonomy of inlinked Web entities: What does it imply for webometric research?

Hyperlinks from other Web sites are, in some respect, similar to bibliographical citations. Link analysis, like citation analysis in bibliometrics, has emerged as a research area of webometrics in recent years. But why are links made and where do they point? A sample of inlinked Web entities (i.e., Web pages or Web sites) was randomly selected from a group of academic institutions' Web sites. The inlinked sites, along with the hyperlink data and outlinking sites, were analyzed and categorized to form a taxonomy of inlinked sites. Based on this taxonomy, a list of reasons for hyperlinking, grouped in four top-level categories (teaching/learning, research, service, and home page), was identified. Compared with bibliographical citations, hyperlinks were made for a different set of reasons. Hyperlinking also has fewer dimensions, less complexity, and little negative implication. On the whole, almost 50% of all the inlinks examined were created for pointing to resource or directory information provided at the target Web sites. In addition, nearly three fourths (73%) of all the inlinked sites analyzed in this study were linked to for reasons relating to service or home page while less than one third (27%) of the links were made out of research or teaching/learning motivations. Yet, teaching and research are the two major criteria traditionally used for evaluating academic institutions. These findings, although by no means conclusive, suggest that evaluative link-based studies should not only consider link counts but also reasons for hyperlinking in order to ensure the validity of such research.     

基于模糊聚类的超链分析算法

基于关键字匹配的搜索引擎排序网页时仅仅考虑评价网页的重要性,而忽视分类;基于分类目录的搜索引擎很难动态分析Web信息。本文在分析它们不足的前提下,提出利用模糊聚类的方法对搜索引擎的检索结果进行动态分类,依据超链分析算法PageRank和Web文档隶属度相结合进行分类排序,并给出具有调节值的结合公式。实验证明,该算法能够更有效地满足用户的需要,提高检索效率。

基于超链分析的Web资源自动发现技术

传统的Web资源自动发现是基于Web页面内容实现的。本文试图从超链分析的角度探讨Web资源的自动发现技术。超链分析技术起源于社会网络分析和科学引文分析理论,它只分析页面之间的关系,而不关心页面本身的属性。通过试验证明,单纯使用超链,根据用户提供的网页实例,我们能够自动发现与学科资源相关的网站。该技术可以有效的减少网络爬行器的无谓爬行,提高采集效率,减轻网络负担,在学科资源建设中起了重要的作用。

Mapping the Cyber-Stakeholders: U.S. Energy Policy on the Web

This article looks to decentered hyperlinking patterns on the worldwide web as a site where media researchers can investigate the treatment of social issues by websites. Such “issue networks” are offered in contrast to the increasingly portalized and commercial nature of information architecture and interfaces on the worldwide web. The article searches for commonly linked sites on the issue of the Bush-Cheney energy policy in an attempt to uncover the hyperlink patterns and debate among the most interconnected sites.     

A fair history of the Web? Examining country balance in the Internet Archive

The Internet Archive, an important initiative that maintains a record of the evolving Web, has the promise of being a key resource for historians and those who study the Web itself. The archive's goal is to index the whole Web without making any judgments about which pages are worth saving. The potential importance of the archive for longitudinal and historical Web research leads to the need to evaluate its coverage. This article focuses upon whether there is an international bias in its coverage. The results show that there are indeed large national differences in the archive's coverage of the Web. A subsequent statistical analysis found differing national average site ages and hyperlink structures to be plausible explanations for this uneven coverage. Although the bias is unintentional, researchers using the archive in the future need to be aware of this problem.     

Evolution of Online Campaigning: Increasing Interactivity in Candidate Web Sites and Blogs Through Text and Technical Features

Political candidates have responded to the public's desire to use the Internet as an interactive information source by creating their own online presence. This study is a content analysis of the Web sites and blogs of the 10 Americans vying to be the Democratic candidate for the 2004 presidential election. Focusing on interactivity, data indicated front pages hyperlink to participation areas such as Donation or Volunteer sections and rarely linked to external content. Blogs used hyperlinks at a rate less than Web sites. Interactivity was encouraged through text, as 83.7% of Web sites asked voters to become more involved. Blog posts discussed issues and attacked the opponents, including President Bush. For the most part, blog posts were personal in nature and used direct address. The tactical use of advanced Web site features showed a technological progression of political campaigning and an overall increase in interactivity through technology and text.

Incorporating web browsing activities into anchor texts for web search

Anchor texts complement Web page content and have been used extensively in commercial Web search engines. Existing methods for anchor text weighting rely on the hyperlink information which is created by page content editors. Since anchor texts are created to help user browse the Web, browsing behavior of Web users may also provide useful or complementary information for anchor text weighting. In this paper, we discuss the possibility and effectiveness of incorporating browsing activities of Web users into anchor texts for Web search. We first make an analysis on the effectiveness of anchor texts with browsing activities. And then we propose two new anchor models which incorporate browsing activities. To deal with the data sparseness problem of user-clicked anchor texts, two features of user’s browsing behavior are explored and analyzed. Based on these features, a smoothing method for the new anchor models is proposed. Experimental results show that by incorporating browsing activities the new anchor models outperform the state-of-art anchor models which use only the hyperlink information. This study demonstrates the benefits of Web browsing activities to affect anchor text weighting.     

The Web and the Unassailable Voice

In most existing art museum Web pages, the values of the museum dominate the values of the Web. Therefore, museum Web pages often electronically duplicate familiar museum products – floor plans, collection catalogues, event calendars – rather than transforming the idea of the museum by adapting the values of the Web.This paper will seek to show how art museums and technologists can come to understand each other and use their differences productively by:1. Orienting museum Web sites towards projects that can only be done on the Web and not on paper.2. Using the Web to overcome the many limitations to understanding imposed by the physical art museum.3. Using the interactive potentials of the Web to change the one-way flow of information from art museum to visitor to a two-way flow which also moves from visitor to museum.4. Infusing the orientation towards constant change into the art museum so that the Web helps the art museum to reinvent itself.     

Modelling the Triple Helix of university-industry-government relationships with game theory: Core,Shapley value and nucleolus as indicators of synergy within an innovation system

The Triple Helix of university-industry-government relationships is a three-person cooperative game with transferable utility. The core, the Shapley value and the nucleolus are suggested as indicators to measure the synergy between innovation actors. The core is the expression of actors’ interests and constraints exerted on them; it measures the extent of the synergy. The Shapley value indicates actors’ strength to lead to and create synergy; and the nucleolus determines the power of coalitions to maintain synergy. The Triple Helix games of the South Korean and the West African innovation systems are studied, based on bibliographic data collected from Web of Science over a ten-year period (2001–2010). Results show that the core of South Korea is larger than that of West Africa, meaning that synergy occurs more within the South Korean innovation system than in the West African one. University has more power to lead to and create synergy and coalitions involving government work in order to maintain synergy.

Understanding Celebrity Endorsers in Cross-cultural Contexts: A Content Analysis of South Korean and US Newspaper Advertising

Based largely on McCracken's ‘cultural meaning transfer’ model (1989), which stresses the cultural meanings of celebrity endorsers, this study explores the characteristics that differentiate celebrity-endorser strategies in South Korean newspaper ads from those in US newspaper ads. With Hofstede's cultural typology—uncertainty avoidance and power distance—as a theoretical framework, this study finds that ads in South Korea with a high uncertainty avoidance and a high power distance culture present a higher proportion of celebrity endorsers than those in the US with a low uncertainty avoidance and a low power distance culture. However, US ads have a greater proportion of product-related celebrity endorsers in both high- and low-involvement product ads. The study also provides detailed information on foreign celebrity endorsers presented in international product ads.

Anti-Korean sentiment and online affective community in Taiwan

This paper examines the rise of anti-Korean sentiment in contemporary Taiwan particularly at the turn of the 2010s. It moves beyond conceptualizing emotion as psychological status to conceive anti-Korean sentiment as a cultural text that debunks the complexity of emotion as an active agent of collective (un)consciousness. Specifically, the paper considers anti-Korean sentiment in Taiwan as an affective space where young Taiwanese demonstrate their active engagement in (re)locating Taiwan in the global imaginative map and their struggle for national identity in the midst of increasing geopolitical tensions in East Asia. Instead of seeing anti-Korean sentiment from an international relations perspective, this paper studies anti-Korean sentiment from a bottom-up perspective through in-depth interviews with young Taiwanese who are actively engaging with anti-Korean discussions and explore various ways that anti-Korean sentiment mediates and transforms imaginative relations between Taiwan and Korea and beyond.
