LSA-based Cognitive Models
This event took place on Wednesday 01 December 2010 at 11:30

 
Sonia Mandin Université Pierre-Mendès-France

This seminar concerns the design of technology enhanced learning environments to improve their learning through reading and writing activities. So far, We have tested (1) The effect of informative feedback on the computerized note-taking from an online course with students, (2) The effect of feedback on the production of a summary or a synthesis on the control of these activities and the understanding of the documents read and researches from students about the European project LTfLL.

Among these various studies, the most important research concerns the summary activity, an activity that allows learners to train their understanding and to assess it.

A large part of the work presented in this seminar relates to the computational modeling of cognitive processes used in understanding and writing activities. These models allow us to better understand the learner. They are based on latent semantic analysis and are used for predictive purposes in the systems designed.

More generally, with an original approach based on theories borrowed from different fields (psychological, educational, computer), we are trying to answer the question: how to assist learners to improve their reading comprehension and written production?

Future Internet is...


Future Internet
With over a billion users, today's Internet is arguably the most successful human artifact ever created. The Internet's physical infrastructure, software, and content now play an integral part of the lives of everyone on the planet, whether they interact with it directly or not. Now nearing its fifth decade, the Internet has shown remarkable resilience and flexibility in the face of ever increasing numbers of users, data volume, and changing usage patterns, but faces growing challenges in meetings the needs of our knowledge society. Globally, many major initiatives are underway to address the need for more scientific research, physical infrastructure investment, better education, and better utilisation of the Internet. Within Japan, USA and Europe major new initiatives have begun in the area.

To succeed the Future Internet will need to address a number of cross-cutting challenges including:

  • Scalability in the face of peer-to-peer traffic, decentralisation, and increased openness

  • Trust when government, medical, financial, personal data are increasingly trusted to the cloud, and middleware will increasingly use dynamic service selection

  • Interoperability of semantic data and metadata, and of services which will be dynamically orchestrated

  • Pervasive usability for users of mobile devices, different languages, cultures and physical abilities

  • Mobility for users who expect a seamless experience across spaces, devices, and velocities
