Web2.0及其对互联网的影响

从近期互联网上出现的新名词"Web2.0"展开,回顾了40余年来互联网模式的演进;对互联网出现的新应用和模式进行了讨论和阐述;总结了Web2.0的概念和内涵并指出Web2.0有可能成为未来Internet的一个发展方向;最后,以Web2.0的特点出发,详细讨论了在Web2.0的影响下,互联网可能发生的变化和未来的特点.     

互联网Web 2.0主流技术及其发展趋势

一、什么是互联网Web 2.0技术 互联网Web 2.0技术是相对于Web1.0技术而言的,是Web 1.0技术的提高和革新.Web 1.0技术是指网站制作发布网页,用户被动、单纯浏览网页的模式.Web 1.0技术是以网站提供集中信息给读者,满足广大用户共同需求为目的的,如现在常见的一些门户网站.     

Web2．0奔跑进行时

Web2.0不是独立存在的,在2006年将会全面融入互联网,这种融入并不意味着Web2.0以及Web2.0所代表的创新浪潮的消退,反而将以这种充满活力的创新方式引发互联网产业格局的巨大变革。Web2.0,在奔跑。

十年追忆:Web 2.0的质疑

当流行的热潮过去之后,我们才能清醒地认识事物的本质。互联网的脚步跨入本世纪之后,网络技术的革命催生了Web2.0,形形色色的Web 2.0的技术形式粉墨登场,让我们觉得在网络时代,技术已经不是问题,适应才是生存的选择。Web 2.0铺天盖地而来,把我们笼罩其中。当我们目不暇给地撞入博客、维基、标签、聚合等的怀抱中时,蓦然回首,忽然发现身后的BBS、BT、Google原来也是Web 2.0前辈,不禁有些哑然失笑。融入P2P的理念之后,迅雷都能成为Web 2.0的代表,而网游,则早就名副     

基于GRDDL的Web2.0与语义Web融合的研究

互联网的发展日新月异,新的概念技术不断的更细和覆盖。对未来互联网的发展有两个相互对立愿景：Web 2.0和语义Web。然而我们相信这两种技术是互补的,而不是竞争。语义Web可以吸取Web 2.0的社会性和互动性,而Web 2.0可以从语义Web中提取有用的智能信息,让所有人随时随地地联系在一起,让整个网络更加智能。本文对Web 2.0和语义Web分别进行阐述,并对两者的融合进行探讨。

谈Web 2.0的安全性

经过10多年的发展,互联网已经迎来第二个发展浪潮-Web2.0时代。尽管针对Web2.0的准确定义还存在着许多争论,但无疑Web2.0已经逐步生根了。无论是从技术角度还是人文角度出发,Web2.0都被赋予了大量的应用,Blog、TAG、SNS、RSS、Wiki等均占据着显赫的位置。Web2.0拥有众多令人激动的崭新应用,新技术的采用所可能产生的新的安全问题逐渐成为了人们关注的焦点。一如Web1.0应用的安全问题,在Web2.0出现具体的、可验证利用的安全漏洞和威胁之前,在设计、发布Web2.0应用时重点需要注意的安全问题也就自然成为了我们讨论的议题。详见P2“谈Web2.0的安全性”一文。     

Web 2.0 Injection Infection Vulnerability Class

ABSTRACT

Web 2.0 defines a changing trend in the use of World Wide Web application development and web design technology. Web 2.0 design concepts have led to the evolution of a web culture that has allowed social-networking and ease of design use of non-secure component applications to enter the business domain of the enterprise. These Web 2.0 component applications are then commingled with other business legacy applications including databases. This article focuses on the taxonomy of the injection infection class of vulnerabilities associated with Web 2.0 application security issues.

Performance improvement of web caching in Web 2.0 via knowledge discovery

Web 2.0 systems are more unpredictable and customizable than traditional web applications. This causes that performance techniques, such as web caching, limit their improvements. Our study was based on the hypotheses that the use of web caching in Web 2.0 applications, particularly in content aggregation systems, can be improved by adapting the content fragment designs. We proposed to base this adaptation on the analysis of the characterization parameters of the content elements and on the creation of a classification algorithm. This algorithm was deployed with decision trees, created in an off-line knowledge discovery process. We also defined a framework to create and adapt fragments of the web documents to reduce the user-perceived latency in web caches. The experiment results showed that our solution had a remarkable reduction in the user-perceived latency even losses in the cache hit ratios and in the overhead generated on the system, in comparison with other web cache schemes.

Migrating from WCAG 1.0 to WCAG 2.0 - A comparative study based on Web Content Accessibility Guidelines in Taiwan

The primary purpose of this research was to explore a comparative analysis of the “Web Content Accessibility Guidelines (WCAG)” standard in Taiwan and the international WCAG standards (WCAG 1.0/WCAG 2.0). The WCAG in Taiwan was established by the Research, Development and Evaluation Commission (RDEC), Executive Yuan in 2002. The WCAG 1.0 was established by the Web Accessibility Initiative (WAI, an organization that created the Web Content Accessibility system) of the World Wide Web Consortium (W3C), and became a W3C standard on May 5, 1999. The WCAG 2.0 became a W3C standard on December 11, 2008.The WCAG in Taiwan was established based on the contents of the WCAG 1.0. However, as the WCAG 2.0 was announced in 2008, check standards based on the WCAG 1.0 were facing revision in all aspects. Therefore, this study aimed at analyzing and comparing the differences between the WCAG 2.0 and the WCAG standards in Taiwan. Utilizing “human check” based on the WCAG 2.0 standard, this study assessed disabilities-related websites conforming to the WCAG standard in Taiwan. Results suggested that migrating from WCAG in Taiwan (based on WCAG 1.0) to WCAG 2.0 does not require a full range revision of webpage design. Suggestions given to disabilities-related websites in Taiwan for developing and providing more complete web accessibility included: (1) websites without accessible design should directly follow the WCAG 2.0 standard in developing web accessibility; (2) future promotion of web accessibility should include all educational institutes and related associations/organizations.For future studies, the resource availability for the disabled and the government achievement in web accessibility after WCAG 2.0 is implemented in Taiwan are topics worth of investigation. Expert opinions and user feedbacks should be included to reflect the actual needs of people with disabilities.     

SweetWiki: A semantic wiki

Everyone agrees that user interactions and social networks are among the cornerstones of “Web 2.0”. Web 2.0 applications generally run in a web browser, propose dynamic content with rich user interfaces, offer means to easily add or edit content of the web site they belong to and present social network aspects. Well-known applications that have helped spread Web 2.0 are blogs, wikis, and image/video sharing sites; they have dramatically increased sharing and participation among web users. It is possible to build knowledge using tools that can help analyze users’ behavior behind the scenes: what they do, what they know, what they want. Tools that help share this knowledge across a network, and that can reason on that knowledge, will lead to users who can better use the knowledge available, i.e., to smarter users. Wikipedia, a wildly successful example of web technology, has helped knowledge-sharing between people by letting individuals freely create and modify its content. But Wikipedia is designed for people—today's software cannot understand and reason on Wikipedia's content. In parallel, the “semantic web”, a set of technologies that help knowledge-sharing across the web between different applications, is starting to gain attraction. Researchers have only recently started working on the concept of a “semantic wiki”, mixing the advantages of the wiki and the technologies of the semantic web. In this paper we will present a state-of-the-art of semantic wikis, and we will introduce SweetWiki, an example of an application reconciling two trends of the future web: a semantically augmented web and a web of social applications where every user is an active provider as well as a consumer of information. SweetWiki makes heavy use of semantic web concepts and languages, and demonstrates how the use of such paradigms can improve navigation, search, and usability.     

A model-driven approach to building modern Semantic Web-Based User Interfaces

The Semantic Web has widely spread in the last 10 years as a suitable web platform to support semantics and expressive information seeking. However, one of the main problems with this paradigm is still the representation and manipulation of ontologies as well as the complex relationships that they implicitly represent. Actually, this remains a challenge when unskilled users have to deal with this abstract representation in order to carry out daily solving-problem activities (e.g., designing web applications based on ontologies). This probably made the Semantic Web to decrease in popularity, also being commercially unsupported and overcame by recent technologies and services based on the Web 2.0, the emerging end-user-focused web concept. All in all, the specification of Model-Based User Interfaces fits very well to both paradigms. Accordingly, the aim of this work is to provide new ways of modeling user interfaces based on semantic models that better fit the domain problem. At the same time, we think of exploiting interactive features through current and modern end-user programming elements based on the Web 2.0, finally contributing to an architecture that supports higher interactive end-user interfaces on the web.
