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
