We present Ontuition, a system for mapping ontologies. Trans- forming data to a usable format for Ontuition involves recog- nizing and resolving data values corresponding to concepts in multiple ontological domains. In particular, for datasets with a geographic component we try to identify and extract enough spatio-textual data that we can assign specific lat/long values to dataset entries. Next, a gazetteer is used to transform the textually-specified locations into lat/long values that can be dis- played on a map. In addition, we discover non-spatial ontolog- ical concepts. This methodology is applied to the National Li- brary of Medicine's very popular clinical trials website (http:// clinicaltrials.gov/) whose users are generally interested in locating trials near where they live. The trials are specified us- ing XML files. We show how to extract the location data and couple it with a disease ontology to enable general queries on the data with the result being of use to a very large group of people. The goal is to do this automatically for such ontology datasets with a locational component.
