Restriction to a predefined set of ontologies, and consequently limitation to specific domain environments is a pervading drawback in Semantic Search technologies. In this work we present PowerAqua [2], a multi-ontology-based Question Answering (QA) platform that exploits multiple distributed ontologies and knowledge bases to answer queries in multi-domain environments. The system interprets the user’s Natural Language (NL) query using the available semantic information, and translates the user terminology into the ontology terminology (triples), retrieving accurate semantic entity values as response to the user’s request
