This paper introduces an evaluated approach to the automatic generation of video narratives from user generated content gathered in a shared repository. In the context of social events, end-users record video material with their personal cameras and ...

In the mid-sixties, Ted Nelson worked at Brown University on an early hypertext system. In 1969, IBM wanted to show the system at a conference, and Nelson gained permission to use Vladimir Nabokov's highly unconventional and hypertextual novel, Pale ...

While the significance of hypertext links for the new ways of telling stories has been widely discussed, there has been not many debates about the very elements that are being connected: hypertext nodes. Apart from few exceptions, poetics of the link ...

In this study we measure the impact of pre-existing social capital on the efficiency of collaboration among Wikipedia editors. To construct a social network among Wikipedians we look to mutual interaction on the user talk pages of Wikipedia editors. As ...

The study of collaboration patterns in wikis can help shed light on the process of content creation by online communities. To turn a wiki's revision history into a collaboration network, we propose an algorithm that identifies as authors of a page the ...

Social tagging is one of the hallmarks of Web2.0. The most common role of tags is descriptive. However, tags are being used for other purposes such as to indicate some actions to be conducted on the resource (e.g. 'toread'). This work focuses on '...

As users turn to large scale social media systems like Twitter for topic-based content exploration, they quickly face the issue that there may be hundreds of thousands of items matching any given topic they might query. Given the scale of the potential ...

More and more, mobile devices act as personal information managers and are able to obtain rich contextual information on the user's environment. Mobile, context-aware web applications can exploit this information to better address the needs of mobile ...

Most wikis do not allow users to collaboratively organize relations among wiki pages, nor ways to visualize them because such relations are hard to express using hyperlinks. The Spatial Hypertext Wiki (ShyWiki) is a wiki that uses Spatial Hypertext to ...

Investigations such as police investigations, intelligence analysis, and investigative journalism involves a number of complex knowledge management tasks. Investigative teams collect, process, and analyze information related to a specific target to ...

People yearn for more integration of their information. But tools meant to help often do the opposite-pulling people and their information in different directions. Fragmentation is potentially worsened as personal information moves onto the Web and into ...

Spatial hypertexts are difficult to explain and to share because we have so little vocabulary with which to discuss them. From examination of actual spatial hypertexts drawn from a variety of domains and created in a variety of systems, we may identify ...

Recent research has shown that different tagging motivation and user behavior can effect the overall usefulness of social tagging systems for certain tasks. In this paper, we provide further evidence for this observation by demonstrating that tagging ...

One of the key motivating factors for information providers to use personalization is to maximise the benefit to the user in accessing their content. However, traditionally such systems have focussed on mainly corporate or professionally authored ...

This paper presents GALE, the GRAPPLE Adaptive Learning Environment, which (contrary to what the word suggests) is a truly generic and general purpose adaptive hypermedia engine. Five years have passed since "The Design of AHA!" was published at ACM ...

A considerable amount of our activities on the Web involves revisits to pages or sites. Reasons for revisiting include active monitoring of content, verification of information, regular use of online services, and reoccurring tasks. Browsers support for ...

In this talk, we will reflect on the evolution of the Web. We will do this by analyzing the reasons why it became the first truly ubiquitous hypertext system against all competitors, and then by looking both at the way it has evolved from a network of ...

Recent advances in Web Science provide comprehensive digital traces of social actions, interactions, and transactions. These data provide an unprecedented exploratorium to model the socio-technical motivations for creating, maintaining, dissolving, and ...
