I am an expert at encoding and processing knowledge, systematizing it through digitally encoded ontologies including rules and taxonomies and interfacing them with NL. I am thorough, diligent, and precise in my work, noting details and logical implications missed by others.

About Me

I encode and process meaning by systematizing knowledge through designing digitally encoded ontologies, constructing ontologies following the designs, instructing other ontologists in building ontologies following the design patterns, and interfacing them with NL. I am thorough, diligent, and precise in my work, noting details and logical implications missed by others.

My Resume


"I have known Doug on a professional basis since mid-2013 when he joined Enterra Solutions reporting to me as part of our Knowledge Team as a Senior Ontologist. Doug has worked on several projects developing, extending and validating core knowledge across several domains, but I think his best skill is that of a "forensic" Ontologist. He has a unique aptitude to perform complex and highly detailed analyses of systems and knowledge to find gaps, conflicts, etc. and provide or suggest solutions. He is also an excellent trainer to assist and explain new concepts to novices in a manner that they can best consume. Please feel free to contact me as a reference."
