Knowledge & Educational Technologies
Knowledge discovery, exchange and creation & learning
changes towards open arrangements due to
 usage of internet & social media applications
 collaboration between users
 availability of new (mobile) devices
 continuous connectivity
Application perspective
 User is overcharged and need support
 High autonomy of users leads to little external control
Technological perspective
 Ecology (heterogeneity and continuously development) of
applications and devices
 Extensive data and resources
Adaptation (adaptivity and adaptability) mechanisms to
support users in learning, teaching and knowledge
discovery and exchange processes
 Context aware & personalized services
 Recommender Systems
 Analysis of textual information & resources
