Glen Hart currently leads the research group at Ordnance Survey, Great Britain's national mapping agency. Glen first began to investigate the Semantic Web in 2002, initially working to understand the relevance to data integration and then how to construct ontological descriptions of geographical objects. Mirroring his interest in vernacular geography (how people understand and refer to the landscape around them as opposed to official views), Glen was also determined to develop ways to make ontologies more accessible to domain experts, those people expert in a subject area but for whom ontologies expressed in formal logic were totally opaque. This resulted in the development of a syntax for the Web ontology language OWL called Rabbit that expresses OWL sentences using controlled natural language. More recently, Glen has been involved in the publication of Ordnance Survey's Geographic Information as Linked Data. Glen sees the publication of Linked Data as an enabler towards more efficient and accurate data integration, and his research continues along these lines.

Dr. Catherine Dolbear is currently a link data architect at Oxford University Press (OUP), working on strategies for linking content across online academic and journal products within OUP's discoverability program. Catherine is the author of several papers in areas of geographical ontology development, semantic data integration, and information filtering using structured data; a previous cochair of the OWL Experiences and Directions Workshop; and cofounder, along with Glen Hart, of the international workshop series Terra Cognita on geospatial semantics. While leading the geosemantics research team at Ordnance Survey, Catherine worked on the development of several ontologies in the geographic domain as well as the reuse of these in application areas such as flood defense and risk management. More recently, she has been interested in moving semantic technologies into mainstream publishing and tackling the scale, quality, and workflow requirements thereof. She is interested in how people think about the world, what is important to them, and how to discover knowledge by forging new links between information.

It is unusual to enthuse over a book on such a technical topic, but this volume is a gem. ... It fully meets [the authors'] objective of being a practical guide to implementing solutions based on Linked Data and the Semantic Web that involve Geographic Information. The practical experience of the authors shines through and the text is complete and precise enough to allow little scope for argument over academic detail. But my greatest praise is for its readability. To produce a book that is such a pleasure to read on ... such a technical topic is an outstanding achievement. ... [Hart and Dolbear] have a rare talent for making complex concepts clear and the potentially dull sparkle. -Mike Jackson, Ph.D., FRICS, FRGS, Emeritus Professor for Geospatial Science, Nottingham Geospatial Institute, The University of Nottingham, UK
