Effect of Document Enrichment on e-Learning

In order to realize the idea of document enrichment we developed a tool called TermPedia which predicts and defines technical terms in educational text. The definitions are extracted from Wikipedia, and the technical terms are also linked to contextually relevant Wikipedia articles which provide further explanation for the definitions. This paper presents results from a user study that was carried out to determine the effect of document enrichment on e-learning from educational documents (textbooks). In particular the study tried to answer the following questions, 1. Does document enrichment improve understanding of e-content? 2. Does document enrichment reduce the time needed for e- learning from an educational document?.
