Summarizing, Visualizing and Correcting Large Collections of Medical Terms

Biomedical professions have collected large ontologies of medical terms covering diseases, diagnosis, drugs, anatomy, bacteria, genes, chemicals, medical procedures and more. We developed a theoretical framework to create concise summaries of large ontologies and software tools to visualize these summaries. Using this software, medical experts can easily browse large medical ontologies, making it easier to recognize errors in structure and content. Recently, we developed machine learning methods for updating and curating biomedical ontologies. We are also developing methods to interpret large collections of formal medical knowledge in ontologies, which will aid in the prediction of dangerous drug interactions.
