Ontology Summit 2011 Focus

Theme: "Making the Case for Ontology"

Description, Goals & Objectives

While the field of ontology, in the information science sense, has blossomed since the late 1980s, the use of ontology in commercial applications still has not been fully exploited, much less recognized by the mainstream technical community. Many in the ontology community are asked for good examples where using an ontology brings clear benefits to addressing a commercial need - indeed the quest continues for the "killer app" for ontology.

This year's Ontology Summit seeks to address this need to provide concrete evidence of successful deployment of ontologies by examining several application domains for such examples, and in better articulating where different "strengths" of ontological representation are best applied. To support these concrete examples, the summit also aims to classify the categories of applications where ontology has been, and could be, successfully applied; to identify distinct types of metrics that might be used in evaluating the return on investment in an ontology application (cost, capability, performance, etc.); to lay out some strategies for articulating a case for ontological applications; and to identify remaining challenges and roadblocks to a wider deployment of such applications that represent promising application areas and research challenges for the future. The findings of the summit are documented in the form of a communiqué intended for public consumption.

Process & Deliverables

Similar to our last 5 summits, this Ontology Summit was comprised of 3 months of virtual discourse (over our archived mailing lists) and virtual panel sessions (over augmented conference calls), and culminated in a 2-day face-to-face workshop/symposium held on April 18-19, 2011 at NIST (Gaithersburg, Maryland, US) during which we, among other things, distilled our thoughts into a collaboratively developed communiqué.
