Ontology-based semantic query for clinical trials

The extensive medical terminology used to describe clinical trials complicates Key words searches to locate resources.This paper presents an ontology-based semantic query system for clinical trial descriptions.This system uses the Web ontology language(OWL) to create the ontology based on ICD-10 and ICMJE(the ontology includes a clinical trial class and a disease class),retrieves clinical trial data from ClinicalTrials.gov,annotates the data as instances of the clinical trial class and creates relationships between the clinical trials and diseases to enable structured semantic clinical trial queries using SPARQL.Through this method,users can use disease and property Key words to express the structured semantic query and locate the resources.The query conditions generated by this method more accurately meet the user's needs than traditional queries.
