Collaborative websites, or wikis, are being used in the classroom to recruit user attention and to disseminate information [1). These wikis place a heavy emphasis on text, while generally neglecting graphics. Little to no research has examined the impact of this textual approach. This paper examines the use of graphics and rule systems as motivating tools in academic wikis. It reports the resul...

In this paper we investigate the effect of different external representations on the process and product of collaborative computer modeling tasks. Shared representations can significantly influence the processes of modeling and communication. We compare pairs working on a collaborative modeling task using a text based model representation with others using a graphical representation. Results in...

This paper describes an integrated architecture for online collaborative multimedia (audio and text) meetings which supports the recording of participants' audio exchanges, automatic metadata generation and logging of users editing interaction and also information derived from the use of group awareness widgets (gesturing) for post-meeting processing and access. We propose a formal model for ti...

This study had intention to evaluate the Wiki tool, of the Moodle in accordance with the performance of the pupils. A research with pupils was carried through who used the Virtual Environment of Learning, in which they had engaged in the construction of a collaborative text, showing the importance/consequences of the use of Information Technology and Communication in small and medium and midsiz...

The development of knowledge systems has been driven by changing approaches, starting with special purpose languages in the 1960s that evolved later to dedicated editors and environments. Nowadays, tools for the collaborative creation and maintenance of knowledge became attractive. Such tools allow for the work on knowledge even for distributed panels of experts and for knowledge at different f...

Agglomerating results from studies of individual biological components has shown the potential to produce biomedical discovery and the promise of therapeutic development. Such knowledge integration could be tremendously facilitated by automated text mining for relation extraction in the biomedical literature. Relation extraction systems cannot be developed without substantial datasets annotated...

This paper describes a collaborative modeling environment to support the analysis and interpretation of statutory texts, i.e., laws. The paper performs a case study on formalizing the product liability act and proposes a data-centric process that enables the formalization of laws. The implemented application integrates state-of-the-art text mining technologies to assist legal experts during the...

A problem with collaborative development of documents is that people can interfere with each other’s work. If unresolved, this interference can result in an incorrect document. A evaluation scenario using the development of a database design is proposed as a good context for evaluation of collaborative systems for the development of both text and diagram documents. Several metrics and measures ...

This article describes a hybrid tool for collaborative information management and retrieval – procspace – that draws on different approaches in the field in order to show in what way those methods can be combined into a single application targeted for use by researchers in the humanities. Integrating data-mining models (such as the vector-space model) into collaborative text filtering can combi...
