OntoReason Company Overview

OntoReason brings a semantic approach to healthcare knowledge management that helps healthcare vendors, biomedical researchers, public health organizations, and government agencies improve the quality, comparability, and accessibility of clinical information. We leverage the semantic representation of standard terminologies and vocabulary services and integrate these with an organizations local vocabulary, thus forming a robust, interoperable foundation that allows the development and adoption of a consistent set of knowledge bases that support the assimilation of an organizations data into powerful information and actionable knowledge.
