Proceedings of the nineteenth ACM conference on Hypertext and hypermedia

Welcome to the 19th ACM Conference on Hypertext and Hypermedia -- Hypertext 2008. One of the great joys of the Hypertext conference series has always been the diversity of the topics that the conference encompasses. Regular attendees have always known and valued this diversity, but the conference steering committee have been aware that it can be confusing to newcomers, and at times difficult for reviewers who have to decide whether a paper is 'in-scope' for the conference. This year we have refined the approach that we began last year, whereby we have had four separate tracks, each with their own chairs and committees; these committees have been responsible for selecting and briefing their reviewers and advertising the call for papers into their communities. We believe that this approach has made the conference more accessible to newcomers, and this has been reflected in the increased quantity and quality of papers submitted. The conference theme this year is "linking people and places" and celebrates the power and importance of the link, in its widest sense. The first track, Information Linking and Organization, specifically targets the formal study of scholarly, structural, sculptural, spatial, open, dynamic and adaptive or any other type of hypertext (or Web-based Information System). In this track, researchers discuss models, architecture, interfaces, properties, or theory in general, about hypertext and hypermedia. The second track, Applications of Hypertext, has been for many years the most difficult for people to scope; it targets descriptions of applications of hypertext, for example in healthcare, cultural heritage, education or industry, where the affordance of the link has in some way enabled a novel application. The third track, Hypertext, Culture, and Communication, examines the creation and reception of literary machines ranging from literary fiction to creative nonfiction and scholarly argumentation. As hypertext reading and writing become ever more pervasive in society, the rhetoric of links continues to offer frequent surprises and unexpected opportunities. This year's papers integrate fresh insights into spontaneous forms and ephemeral social media with considered reflection on carefully crafted hypermedia. Social Linking track expands the remit of the Social Hypertext track introduced in 2007. This track focuses on one of the most exciting recent developments in Web science, social annotation, by which users can easily markup other authors' resources via collaborative mechanisms such as tagging, filtering, voting, editing, classification, and rating. These social processes lead to the emergence of many types of links between texts, users, concepts, pages, articles, and media. The social linking track has immediately established itself as the most popular venue for this year's Hypertext technical submissions, covering several aspects of design, analysis, and modeling of information systems driven by social linking. The accepted papers represent a high-quality sample of research covering a broad range of social linking topics, which include the co-evolution of social, information, and semantic networks; formal models of social annotation and its behavioral patterns; link inference from blogs and social networks; applications to search, retrieval, recommendation, navigation, and scalability issues; information-theoretic aspects of socially-induced semantic networks; structure and dynamics of social information networks; and evaluation of mechanisms and interfaces for social linking systems. This is the third time the Hypertext Conference has been held in Pittsburgh. We are very fortunate, this time, to have excellent keynote presentations from Bernardo Huberman of HP Labs and Prof. Jon Kleinberg of Cornell University, and an excellent technical and social program to look forward to. In addition to the contributions featured in this volume Hypertext 2008 offered two workshops: ;) Web Science: Collaboration and Collective Intelligence organized by Weigang Wang (University of Manchester, UK) and David Millard (University of Southampton, UK) Creating out of the Machine: Hypertext, Hypermedia, and Web Artists Explore the Craft organized by Stephen Ersinghaus (Tunxis Community College, Connecticut, USA) )

欢迎参加第19届美国计算机协会超文本与超媒体会议——2008年超文本会议。超文本会议系列的一大乐趣一直在于会议所涵盖主题的多样性。常客们一直了解并重视这种多样性，但会议指导委员会意识到这可能会让新手感到困惑，有时也会让评审人员难以决定一篇论文是否在会议的“范围之内”。今年我们改进了去年开始采用的方法，即我们设立了四个独立的分会场，每个分会场都有自己的主席和委员会；这些委员会负责挑选和向评审人员介绍情况，并在各自的社区宣传征稿事宜。我们相信这种方法使会议更容易被新手接受，这从提交论文的数量和质量的提高上就可以体现出来。 今年会议的主题是“连接人与地方”，从最广泛的意义上颂扬了链接的力量和重要性。 第一个分会场，信息链接与组织，专门针对学术性、结构性、雕塑性、空间性、开放性、动态性和适应性或任何其他类型的超文本（或基于网络的信息系统）的正式研究。在这个分会场，研究人员讨论超文本和超媒体的一般模型、架构、接口、属性或理论。 第二个分会场，超文本的应用，多年来一直是人们最难确定范围的；它针对超文本应用的描述，例如在医疗保健、文化遗产、教育或工业领域，其中链接的功能在某种程度上促成了一种新颖的应用。 第三个分会场，超文本、文化与传播，研究从文学小说到创意非虚构作品和学术论证等各种文学作品的创作和接受。随着超文本阅读和写作在社会中变得越来越普遍，链接的修辞学不断带来频繁的惊喜和意想不到的机会。今年的论文将对自发形式和短暂社交媒体的新见解与对精心制作的超媒体的深思熟虑相结合。 社会链接分会场扩大了2007年引入的社会超文本分会场的职责范围。这个分会场关注网络科学中最近最令人兴奋的发展之一——社会标注，通过这种方式用户可以通过诸如标签、过滤、投票、编辑、分类和评级等协作机制轻松地标记其他作者的资源。这些社会过程导致了文本、用户、概念、页面、文章和媒体之间多种类型链接的出现。社会链接分会场立即成为今年超文本技术投稿最受欢迎的场所，涵盖了由社会链接驱动的信息系统的设计、分析和建模的多个方面。被接受的论文代表了高质量的研究样本，涵盖了广泛的社会链接主题，包括社会、信息和语义网络的共同进化；社会标注及其行为模式的正式模型；从博客和社交网络推断链接；在搜索、检索、推荐、导航和可扩展性问题上的应用；社会诱导语义网络的信息论方面；社会信息网络的结构和动态；以及社会链接系统的机制和接口的评估。 这是超文本会议第三次在匹兹堡举行。这次我们非常幸运，能听到惠普实验室的贝尔纳多·休伯曼和康奈尔大学的乔恩·克莱因伯格教授的精彩主题演讲，还有令人期待的精彩技术和社交活动安排。 除了本卷所收录的内容外，2008年超文本会议还举办了两个研讨会： 由王卫刚（英国曼彻斯特大学）和大卫·米勒德（英国南安普敦大学）组织的“网络科学：协作与集体智慧” 由斯蒂芬·埃尔辛豪斯（美国康涅狄格州通西斯社区学院）组织的“机器之外的创造：超文本、超媒体和网络艺术家探索技艺”
