Title: The Knowledge Graph Extraction Virtuous Circle Abstract: Knowledge graphs such a NELL, Freebase, and YAGO provide a means to address the knowledge bottleneck in artificial intelligence domains such as natural language processing,  computer vision, and robotics. State of the art knowledge graphs have accumulated large amounts of beliefs about real world entities using machine reading methods.  Current machine readers have been successful at populating such knowledge graphs by means of pattern detection — a shallow way of machine reading which leverages the redundancy of large corpora to capture language patterns. However, machine readers still lack the ability to fully understand  language. In the pursuit of the much harder goal of language comprehension, knowledge graphs present an opportunity for a virtuous circle:  the accumulated knowledge can be used to improve machine readers; in turn, advanced reading methods can be used to populate knowledge graphs with beliefs expressed using complex and potentially ambiguous language. In this talk, I  will elaborate on this virtuous circle, starting with building knowledge graphs, followed by results on using them  for machine reading. Bio: Ndapandula Nakashole is a postdoctoral fellow at Carnegie Mellon University. She works with professor Tom Mitchell on using machine learning to build computer systems that intelligently process and understand human language. Ndapa received her PhD from the Max Planck Institute for Informatics and Saarland University, where she was awarded the Otto Hahn Medal  for her dissertation. She completed her  B.Sc and M.Sc at the University of Cape Town.
