A QUERY FORMULATION LANGUAGE FOR DATA WEB?

This trend of structured data on the web is shifting the focus of the web technologies toward new paradigms of structured ?data retrieval. Traditional search engine cannot serve such data as the result of a keyword based. Query will not be precise or clean, because the query itself is still ambiguous although the underlying data are structured. To expose the massive amount of structured data on the web to its full potential, people should be able to query these data easily and effectively. We present a query formulation language(called MashQL) in order to easily query and fuse structured data on the web the main novelty of MashQL is that it allows people to navigate, explore, query and mash up data sources without prior knowledge about the schema, structure, vocabulary, or any technical details of the sources.
