Transforming data to a usable format for Ontuition involves recognizing and resolving data values corresponding to concepts in multiple ontological domains. In particular, for datasets with a geographic component an attempt is made to identify and extract enough spatio-textual data that specific lat/long values to dataset entries can be assigned. Next, a gazetteer is used to transform the textually-specified locations into lat/long values that can be displayed on a map. Non-spatial ontological concepts are also discovered. This methodology is applied to the National Library 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 using XML files. The location data is extracted and coupled 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. %B Proceedings of the 18th SIGSPATIAL International Conference on Advances in Geographic Information Systems %S GIS '10 %I ACM %C New York, NY, USA %P 540 - 541 %8 2010/// %@ 978-1-4503-0428-3 %G eng %U http://doi.acm.org/10.1145/1869790.1869887 %R 10.1145/1869790.1869887
