The method is divided into phases that use: (i) exact string-matching to calculate subsequences of links that were repeated in different navigation sessions (common trails through the website), and then (ii) inexact matching to find other similar sessions (a community of users with a similar interest). The evaluation showed how subsequences could be used to understand the information pathways users chose to follow within a website, and that exact and inexact matching provided complementary ways of identifying information that may have been of interest to a whole community of users, but which was only found by a minority. This illustrates how string-matching could be used to improve the structure of hypertext collections.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"436 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116008979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its development started in 1996. During 10 years of research and development different new presentation, adaptation and user modeling methods and techniques have been added, turning AHA! into a general-purpose adaptive hypermedia platform. This paper presents an overview of the design and architecture of AHA!, with parts that have been published before and with recent additions like style adaptation and a new very flexible link annotation mechanism.Unlike other adaptive hypermedia systems, AHA! is not aimed at a single application area and does not prescribe a single fixed presentation style. Creating applications, defining the user models and the adaptive behavior are all done using graphical authoring tools. End-users are presented with what looks like a normal website, and need not be aware of the adaptation that goes on behind the scenes. Their browsing results in updates to a user model that is stored either in an xml file or a mySQL database, and that is thus also (in principle) available to other applications.Apart from providing a design overview this paper highlights two essential parts of AHA!: the reasoning / rule engine that translates the end-user's actions into user model updates, and the adaptive resource selection, which is used in the conditional inclusion of objects presentation technique and in the conditional link destinations navigation support technique.This paper is itself an adaptive hyperdocument. The order in which the different topics are visited determines the links that are presented and the contents of each (web)page. No matter how you browse through this paper you should end up with a very similar overall impression, and you should have seen all the information the paper contains. However, the actual contents of the pages and the actual link destinations do depend on your browsing order, so different users will not see exactly the same pages and links.Although strictly speaking this paper could be presented using normal linear text, making it an adaptive hyperdocument transforms it from being \"just\" a paper into being a paper and a demo all in one.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125668612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collaborative hypermedia systems and standards like BSCW, Wikis, and WebDAV enable people to establish formal and informal collaboration patterns across the Internet. The easy to use Blog/Weblog systems have made it possible for people to establish communities, express opinions, and spark debates over the Internet with minimal effort. Open hypermedia and annotation systems have been developed to support linking and commenting on existing Web documents to support scholarly discourse of online material. Many e-learning applications have been built on top of these systems to provide support for remote learning activities in schools and at workplaces.However, this focus on remote and distributed social networks has to some degree taken the focus away from social networks and collaboration among people who share the same physical environment whether face-to-face or over time. Physical environments in this context may be public spaces or buildings such as workplaces, schools, libraries, museums, and homes. Some of the technologies listed above may of course be applied by people who are in close proximity to each other who shares the same space over time, but I will argue that there is a need to focus on and conduct research in new ubiquitous hypermedia infrastructures and interaction techniques to also support social interaction and networking among people who share the same physical environment.In the Center for Interactive Spaces and predecessor projects, we have focused on the development of various kinds of ubiquitous hypermedia infrastructures and applications that support collaboration or social interaction among proximate peers at work, at school, at libraries, at museums, etc. We are applying various augmented reality tagging mechanisms (e.g., geo-tags, RFID, Bluetags, and visual tags) to provide hypermedia links among digital resources, people, objects and places. We are applying various mobile, spatial, and multi-user interaction techniques to provide new types of interfaces for social interaction in physical spaces.In the Center for Interactive Spaces we have developed several examples of ubiquitous hypermedia applications: eBag -- an electronic schoolbag system with seamless login based on bluetooth ID; iFloor -- an interactive floor for libraries and schools providing hypermedia functionality for collective search, exploration, debate, and knowledge sharing; InfoGallery -- an exhibition system for digital resources and debates at libraries, museums, attractions, and cityscapes; HyConExplorer utilizing geo- and RFID-tagging to annotate the outdoor environment for school projects or the like.Related examples from other projects and labs are Slogan-benches from the Presence project in Amsterdam; Informative Art from PLAY at Chalmers University, Sweden; the CatchBob! pervasive game developed at EPFL, Switzerland.The talk will: motivate the rese","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123190282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper surveys annotation techniques from open hypermedia systems, Web based annotation systems, and mobile and augmented reality systems to illustrate different approaches to four central challenges ubiquitous annotation systems have to deal with: anchoring, structuring, presentation, and authoring. Through a number of examples each challenge is discussed and HyCon, a context-aware hypermedia framework developed at the University of Aarhus, Denmark, is used to illustrate an integrated approach to ubiquitous annotations. Finally, a taxonomy of annotation systems is presented. The taxonomy can be used both to categorize system based on the way they present annotations and to choose the right technology for interfacing with annotations when implementing new systems.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122898656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These systems enable users to add keywords (i.e., \"tags\") to Internet resources (e.g., web pages, images, videos) without relying on a controlled vocabulary. Tagging systems have the potential to improve search, spam detection, reputation systems, and personal organization while introducing new modalities of social communication and opportunities for data mining. This potential is largely due to the social structure that underlies many of the current systems.Despite the rapid expansion of applications that support tagging of resources, tagging systems are still not well studied or understood. In this paper, we provide a short description of the academic related work to date. We offer a model of tagging systems, specifically in the context of web-based systems, to help us illustrate the possible benefits of these tools. Since many such systems already exist, we provide a taxonomy of tagging systems to help inform their analysis and design, and thus enable researchers to frame and compare evidence for the sustainability of such systems. We also provide a simple taxonomy of incentives and contribution models to inform potential evaluative frameworks. While this work does not present comprehensive empirical results, we present a preliminary study of the photo-sharing and tagging system Flickr to demonstrate our model and explore some of the issues in one sample system. This analysis helps us outline and motivate possible future directions of research in tagging systems.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126285726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
