In this paper, we represent the context based weighting scheme for vector space model to evaluate the relation between concept and context in Information storage and retrieval system. A meaning of a word is relatively decided by a context dynamically. A vector space model, generally use a static weighting scheme for term document matrix like latent semantic indexing (LSI), co-occurrence or correlations...
MOOCs (Massive Open Online Courses), a new form of learning, are characterized by a large scale of subscription. Thus, appropriate assessment strategies should be implemented to support massive data flows. In this paper, we are interested in studying the Peer Assessment in MOOCs based on Inquiry Based Learning (IBL), iMOOCs. Our contribution is a continuation of our previous research work. In fact,...
The Reference Model for an Open Archival Information System has been extraordinarily influential within the digital preservation community. The Preserving Virtual Worlds project explored the application of the OAIS Reference Model for the preservation of computer games, videogames and electronic literature within a research library setting. This paper identifies practical problems in determining the...
In this paper we define an ontological model to accurately represent the context in Pervasive Computer Supported Collaborative Work. A major issue in this domain is the mass of information required to correctly depict a situation. As we need to represent users and devices according to multiple aspects (physical, computational, social ...) the amount of information can quickly become unmanageable....
A learning process is substantially a knowledge management process. Computers can play multiple roles in human learning and facilitated human learning processes by providing technical, cognitive, and social support. This paper discusses knowledge management in computer-supported learning, explores the knowledge management process in learning process, and suggests how to better support knowledge management...
We introduce F-ALCI, a federated version of the description logic ALCI. An F-ALCI ontology, like its package-based counterpart ALCIP-, consists of multiple ALCI ontologies that can import concepts or roles defined in other modules. Unlike ALCIP- which supports only contextualized negation, F-ALCI, supports contextualization of each of the logical connectives, a feature that allows more flexible reuse...
