Leslie F. Sikos, Ph.D., is a researcher at Flinders University, Australia, specializing in knowledge representation of multimedia resources, multimedia ontology engineering, and automated video scene interpretation via spatiotemporal reasoning and information fusion. He has worked in both academia and the industry, thereby acquiring hands-on skills in Semantic Web technologies, photography, video authoring, CGI, and 3D modeling, and has developed two of the most expressive multimedia ontologies to date, which are formally grounded in description logics and complemented by rulesets. Dr. Sikos is currently working on the standardization of next-generation video indexing techniques that leverage semantic annotation at different levels of granularity, including entire videos, video shots, video segments, video frames, and regions of interest of video frames, and map depicted concepts to Linked Data. Inspired by the creation and exploitation of rich LOD datasets, Dr. Sikos actively contributes to the development of open standards and open data repositories.
