Philipp Cimiano is full professor of computer science at Bielefeld University and head of the Semantic Computing group, affiliated with the Cluster of Excellence on Cognitive Interaction Technology (CITEC). He received his doctoral degree in applied computer science from the University of Karlsruhe (now KIT) on the topic of learning ontologies from text. His main expertise is in the areas of natural language processing, ontology learning, knowledge acquisition and representation, and the multilingual Semantic Web. He was nominated one of AI's 10 to Watch by the IEEE Intelligent Systems Magazine in 2008, an award given to the top 10 young researchers in the field of artificial intelligence worldwide.
Christina Unger is a postdoctoral researcher in the Semantic Computing group. She received her PhD from the Utrecht Institute of Linguistics (UiL-OTS), the Netherlands, in 2010, on the topic of the relationship between syntactic displacement and semantic scope. Her major research interest lies in the area of computational semantics, with a focus on ontology-based natural language understanding, question answering, and the automatic generation of grammars from the lexicon-ontology interface.
John McCrae is a postdoctoral researcher in the Semantic Computing group. He received his PhD from the National Institute of Informatics in Tokyo, in 2009, on the topic of learning consistent ontologies by information extraction. His research interests include the lexicon-ontology interface, the collaborative development and publishing of language resources, and machine translation. He is one of the main developers of the ontology-lexicon model lemon, now being further advanced under the frame of the W3C Ontology-Lexica Community Group.
