Course content

Algorithms for analysing the meaning of words in documents are of crucial importance for a wide range of applications including information retrieval, automatic summarization, or automatic keyphrase extraction. The lecture puts a special focus on the resoures used to provide knowledge for these algorithms. Besides classical semantic wordnets like Princeton WordNet, the lecture also introduces emerging Web 2.0 resources like Wikipedia and Wiktionary.
