SPARQL Query Splitter: query translation between different contexts

Description

When integrating the information of a number of applications, one solution is to provide one or more unified entry points to the applications. A challenging task in this context is to translate the user query, which is posed over the unified entry point, to the integrated applications. The user query is expressed in terms of the entry point schema and the integrated applications do not accept this query because they have different schemes. In this demo, we present SPARQL Query Splitter, a tool that translates SPARQL user queries posed over an entry point schema to a number of queries over the application schemes. Our tool uses the mappings between the schemes to perform the translation by means of a symbolic calculator.
