Inhalt

Knowledge graphs are a powerful and versatile representation of lexical and world knowledge. They are a very special ecosystem of entities/concepts and relations, that define each other and that can be explored and exploited jointly to help with varied NLP tasks, such as question answering, summarization, reasoning.

In this course we will explore the issues of building knowledge graphs, representing them in various ways, learning within knowledge graphs, and learning to further grow them with or without external information.
