PLEM for Edublog Ranking

The poll for the Edublog Awards 2009 closed today. While waiting for the outcome of the voting, I tried to use the PLEM ranking algorithm to rank the nominated blogs in the category "Best individual blog" based on the Wisdom of Crowds and different interaction metrics (PLEM saves and ratings, Delicious saves, Friendfeed comments and likes, Yahoo inbound links, Digg votes, Google Trackbacks, and Technorati blog reactions). To see the result, you can visit the PLEM project Website here, hit the "edublog" tag from the "Popular Tags" list, and choose "Most Popular" as the ranking option. Below is a screenshot of the result. Let's see whether the Edublog Awards voting result will be different or not.

The MobileHost CoLearn system: mobile social software for collaborative learning

The paper "The MobileHost CoLearn system: mobile social software for collaborative learning" has been published in the International Journal of Mobile Learning and Organisation (IJMLO) by Inderscience Publishers. A preprint of this paper can be downloaded here.


Learning and knowledge are fundamentally social in nature – as emphasised by many researchers. In the past few years, there has been an increasing focus on social software applications as a result of the rapid development of Web 2.0 technologies. Furthermore, mobile and ubiquitous technologies have provided capabilities for more sophisticated open social systems, where mobile knowledge sharing is the norm. In this paper, we explore the use of Web 2.0 concepts and social software for learning and present the MobileHost CoLearn system; a mobile web services driven social software for mobile collaborative learning.
