3. MGREP Concept Mapping Engine Single Word Variation Concepts Remove Common Words Combine with Word Order Permutation Radix-tree Match Figure 1. Overview of our free text-to-ontology mapping method Key Idea: While classical concept match algorithms use the time consuming approach of generating concept variations during concept match, mgrep pre-generate concept variations and uses highly efficient string match algorithms to achieve two orders of magnitude increase in speed over MetaMap.
