SPARQL Query-Builder for Medical Temporal Data

Semantic Web technologies and Linked Data approach are widely used in different areas. Patient therapy and treatment are the processes where temporal data naturally occurs. During the treatment there can exist data like clinical reports, imaging examinations or laboratory results and all of them contain information about date and time of the event. Preparing data for analysis is often a hard task. We work with temporal medical data stored in the RDF store with SPARQL Endpoint support. To meet physicians requirements, it is necessary to transform the temporal data from RDF into a spreadsheet for their analysis. Our goal is to make SPARQL builder that can produce SELECT queries. Each query allows required subset of temporal medical data selection using SPARQL Endpoint for follow-up analysis. The builder should auto-configure itself when ontologies, concepts, timepoints, attributes, domain/range constraints, annotations and RDF vocabularies are known. This paper describes a prototype web-oriented application of SPARQL query builder. The main advantage is a simple user interface where even a user without knowledge of SPARQL can make a complex queries that support a multiple attributes selection with different timepoints. A direct use of SPARQL Endpoint is possible. The result tabular data could be then used for analysis by common tools.
