In what ways are advances in information technology likely to affect the processes of scientific research and publication? To study the issues we have developed a web-based knowledge management infrastructure which supports the creation, synthesis and application of scientific knowledge. The purpose of this paper is to present this infrastructure, which we call "Cybrarium", and to highlight cor...

The focus of this paper is ontology-based knowledge management in the framework of a mobile communication and information system for rescue operation management. We present a novel ontology data service, combining prior domain knowledge about large-scale rescue operations with dynamic information about a developing operation. We also discuss the integration of such a data service into a service...

The author is involved in a multi-year program to establish a number of largescale SME collaboration projects. It was anticipated that some web-based tools used previously could be adapted, but limits in the participant firm capabilities and the emergence of a different business model led to a change in approach. In this paper an adaptation of the notion of absorptive capacity where both a firm...

Many universities worldwide have developed a variety of web-based e-learning environments, hoping to benefit from this new and fast spreading IT (Harasim, 2000). The main intention of this paper is to describe an e-learning model that would act as a prudent teacher to teach and test the aptitude of e-learners based on available knowledgebase. Here, we provide an overall view of the proposed mod...

The University of Michigan's natural language processing system, called LINK, is a unificationbased system which we have developed over the last four years . Prior to MUC-4, LINK had been used to extract information from free-form texts in two narrow application domains . One application corpus contained terse descriptions of symptoms displayed by malfunctioning automobiles, and the repairs whi...

Students in civil engineering and mechanical engineering fields may find the concepts of fluid mechanics abstract and have difficulty in grasping the real phenomena. Innovative learning methodologies are necessary to help arouse their interest. Yet, many web-based learning sites have common weaknesses including information being laid out basically in a textbook format and the lack of interactio...

This paper describes the MATHESIS semantic authoring framework being developed within the MATHESIS project. The project aims at an intelligent authoring environment for reusable model-tracing tutors. The framework has three components: an intelligent web-based model-tracing algebra tutor, an ontology and a set of authoring tools. The tutor serves as a prototype for the development of the ontolo...

Data science is an emerging interdisciplinary field that combines elements of mathematics, statistics, computer science, and knowledge in a particular application domain for the purpose of extracting meaningful information from the increasingly sophisticated array of data available in many settings. These data tend to be non-traditional, in the sense that they are often live, large, complex, an...

With the development of Multimedia and networking as well as their extensive application in educational field, the web-based education has been concerned by educational researchers. Against this background, more and more E-learning systems have been established to encounter some bottlenecks of traditional learning. However, many shortcomings of existing e-learning platforms have been exposed ou...

This paper describes the design decisions made in the construction of an online global learning community for grades 7-9 science students. The collaborative learning tools of class profiles, student-scientist forums, and peer review featured in the From Local to Extreme Environments curriculum are discussed in detail. Initial evaluation of these tools and student reactions to global collaborati...
