The relationship between collaboration processes, task strategies and the use of the tools and resources that the computer environment offers, may be crucial for the effects of computer supported collaborative learning. We are interested to find out how, within a computer environment, students collaborate, how they use the different tools we offer and how this influences the quality of the fina...

Current groupware systems do not work well over wireless networks, as a wireless connection is of variable and often poor quality. Our research suggests a number of changes that allow groupware applications to make efficient use of a wireless channel. One fundamental change is providing adaptability, which allows applications to take advantage of favourable network conditions and to react to di...

We establish natural criteria under which normally iterable premice are for stacks of normal trees. Let [Formula: see text] be a regular uncountable cardinal. and an text]-sound premouse text]-iteration strategy (roughly, text]-strategy). define condensation property iteration strategies, inflation condensation. show that if has then is text]-iterable length trees each text]), moreover, we spec...

Integration of text and documents into database management systems has been the subject of much research. However, most of the approaches are limited to data retrieval. Collaborative text editing, i.e. the ability for multiple users to work on a document instance simultaneously, is rarely supported. Also, documents mostly consist of plain text only, and support very limited meta data storage or...

black humor plays a crucial role in fulfilling langston hughes's anti-racist purposes as an integral notionin his poetry. accordingly, translation(s) of his poetry are to benefit from the same indexes onthe basis of equivalent effect principle. on this account, 33 black-humor-rich poems of hughes, translatedby ahmad shamloo, yaghma golruee and hassan fayyad, were selected to be analyzed contras...

Collaborative modeling tools are useful for many tasks within design or learning processes. However, they are difficult to build and are usually domain-specific. In response to this situation, we propose a model-driven method for the development of domain-independent collaborative modeling tools. This method consists of a methodological framework, a conceptual framework and a technological fram...

Most text categorization methods require text content of documents that is often difficult to obtain. We consider “Collaborative Text Categorization”, where each document is represented by the feedback from a large number of users. Our study focuses on the semisupervised case in which one key challenge is that a significant number of users have not rated any labeled document. To address this pr...
