Adapting informal sources of knowledge to e-Learning

The amount of information sources and the available data is growing dramatically fast nowadays. It is very difficult time for teachers to keep up with changes, especially in information domain, and to find new and appropriate sources of information; this problem also affects e-Learning. Contemporary e-Learning systems deliver predefined, rigid courses which usually do not take into account user specific conditions, like wishing to broaden his or her knowledge in wide range of domains at the same time. Without constant maintenance, electronic courses are also getting outdated. Moreover, all of the current solutions seem to underestimate the potential of informal learning [1].
