In this paper we present the evolution of a collaborative courseware generating system that is featured by XML-based course structure representation, JSP-based dynamic courseware presentation, and WebDAV-based collaborative courseware authoring. While the first system implementation employs a proprietary design that uses a self-defined XML DTD to represent course structure, the second and the t...

background: cooperative and collaborative learning approach with online programs is useful in response to rising demand for university educational system. this study evaluates the use of internet and computer in collaborative teaching and learning process for post graduate nursing students. method: this is a correlation descriptive study. the population in the study is based on census sampling ...

Collaborative systems' speciications are complex, due to dynamically changing application structure (as users join and leave the session), concurrency, and interaction in multiuser interfaces. There are few speciication development methods to support these issues. We propose a method and high-level formal languages to specify reconngurable structure and behavior for collaborative systems. The m...

An agent's ability to understand an utterance depends upon its ability to relate that utterance to the preceding discourse. The agent must determine whether the utterance begins a new segment of the discourse, completes the current segment, or contributes to it. The intentional structure of the discourse, comprised of discourse segment purposes and their interrelationships, plays a central role...

Collaborative tagging describes the process by which many users add metadata in the form of keywords to shared content. Recently, collaborative tagging has grown in popularity on the web, on sites that allow users to tag bookmarks, photographs and other content. In this paper we analyze the structure of collaborative tagging systems as well as their dynamical aspects. Specifically, we discovere...

in this study, we introduce and study a concept of distributed fuzzymodeling. fuzzy modeling encountered so far is predominantly of a centralizednature by being focused on the use of a single data set. in contrast to this style ofmodeling, the proposed paradigm of distributed and collaborative modeling isconcerned with distributed models which are constructed in a highly collaborativefashion. i...

It has been claimed that collaborative networks are the societal structure of this century. Nonetheless, low success rates often observed in the practice of purposeful collaboration suggest that our understanding is still limited. In this paper, I advance on the theory of collaborative systems, a systems theoretical approach to interorganizational collaborative relationships, critically investi...

Collaborative categorization is an emerging direction for research and innovative applications. Arguably, collaborative categorization on the Web is an especially promising emerging form of collaborative Web systems because of both, the widespread use of the conventional Web and the emergence of the Semantic Web providing with more semantic information on Web data. This paper discusses this iss...

The integration of practice and learning is a key to cultivation of or­ ganizational capability for creating or inheriting intellect. In this paper, firstly we address the critical research issues for collaborative space design to inte­ grate practice and learning. Following the discussion, we have built an ontology which specifies the structure of the collaborative learning, described patterns...
