This paper discusses how mediation strategies can be used to design a pedagogical agent integrated to a text mining tool to promote collaborative work in academic reading and writing activities. The agent uses the Artificial Intelligence Markup Language (AIML) to communicate with students, while its text mining features enables it to keep track of what is being produced collaboratively. Mediati...

Recent research on interfaces driven by line-markings indicates that there are many potential benefits and applications of such interfaces. Benefits include the exploitation of users' handwriting skills and their skills in understanding handwritten marks. There are systems that have exploited one or the other of these benefits but not both. One application which would take advantage of both of ...

Among several diagrams defined in UML, the class diagram is particularly useful through entire software development process, from early domain analysis stages to later maintenance stages. However conventional UML environments are often inappropriate for collaborative modeling in physically remote locations, such as exchanging models on a public mailing list via email. To overcome this issue, we...

The authors report on the development of the Cancer Tissue Information Extraction System (caTIES)--an application that supports collaborative tissue banking and text mining by leveraging existing natural language processing methods and algorithms, grid communication and security frameworks, and query visualization methods. The system fills an important need for text-derived clinical data in tra...

With the emergence of collaborative knowledge goods such as Wikipedia, the demo­ cratic evolution of documents seems to be a minor step in the further evolution of democracy. However, a proper theory for the development and exploitation of democratic text information systems is missing. We propose the development of a framework for democratic text evolution that includes both techni cal and soc...
