Ontotext, Sirma Media, Sofia, Bulgaria

We have used biology lessons for 5th grade owned by Young Digital Planet ( We have used a sample of 30 multimedia lessons. At first stage, we parsed the internal format and retrieved text attached to each page. Next, we applied a combination of entity-recognition algorithms and web crawling to fetch additional materials. Sources are mostly dbpedia and Encyclopaedia of Life ( As a result, we enriched the original multimedia application with additional links and images. When user moves accross pages of a lesson, links on the right change to reflect the content.
