MapFace - An Editor for MetaMap Transfer (MMTx)

Mapping concepts from medical terminologies, such as the UMLS, to medical documents is a prerequisite for many tasks of (automatically) processing documents. Due to the nature of the UMLS and the tools to accomplish the mapping, it is not always possible to achieve a correct and unambiguous mapping. This drawback led us to the development of an editor for correcting the obtained information. Our editor, MapFace, visualizes information received by the MetaMap Transfer (MMTx) program and enables users to edit and correct this information on both a conceptual and a syntactical level. By means of this functionality we are able to provide further processing steps with correct and appropriate input. Furthermore, the visualization features enable users to validate or even generate hypotheses, as well as support the better understanding of medical text.
