Armin Haller is an Associate Professor of Business Information Systems. His research interests include knowledge graph engineering, ontology engineering, linked data, the Internet-of-Things and the semantic Web in general. Armin has received funding from organisations including: the Department of Finance, to develop an ontology framework for government information and an open-source software that allows domain experts to maintain knowledge graphs called Schímatos; and from the Australian Research Council’s Linkage Program, for a project with Sydney Trains.  He has published in the most prominent academic journals and conferences in his field, including Journal of Web Semantics, Semantic Web Journal, Applied Ontology, World Wide Web Conference and the International Semantic Web Conference. Armin engages with the Australian ICT industry through his managing of the W3C Office Australia. He is also active in several W3C working groups, where he chaired the Semantic Sensor Network Ontology working group. This work has resulted in an international standard for the description of sensors and actuators on the Internet-of-Things and has been published in two journal articles. Armin is a passionate evangelist of Open Government Data and, to this end, has chaired Australian Government Linked Data Working Group for the last 7 years.
