This map is the contextual representation of the Grand challenge Problems (from the ARV 2011). Our goal is to define cooccurrences present in this corpus. We select words that frequently appear around each others. If two words are usually cited closely, they will be linked here in this map. To a word 1, we select 1 to 3 words that appear in its close environment (the context chosen is 50 words before - 50 words after the word). We deleted generic words (learning, technology) for this analysis as it brought too much noise.
