Delivering right information at the right time has been an adage of knowledge management for some time. In this talk Marek Hatala, an assistant professor from the School of Interactive Arts and Technology at Simon Fraser University in Vancouver, revisits this motto in two different contexts.

First, he will show how semantic web and user modeling techniques were employed in a personalized augmented audio-reality environment for museum visitors called ec(h)o. The ec(h)o platform is designed to create a museum experience that consists of a physical installation and an interactive virtual layer of three-dimensional soundscapes that are physically mapped to the museum displays. The source for the audio data is digital sound objects.

In the second part Marek will show how a user model developed in ec(h)o project can be used in other semantically rich applications. He will present LORNET - a 5-year research in the domain of e-learning - focusing on interoperability between learning resources, courses, programs, learner competencies, learner needs, and fellow learners.
