We propose a query formulation language, called MashQL for querying and mashing up structured data on the web. The novelty of MashQL is that it does not require one to know the structure of the queried data or the data itself to adhere to a schema. Being a language not merely an interface and, at the same time, assuming data to be schemafree is one of the key challenges addressed in this article. A novel technique to optimize queries over large graph dataset is proposed in order to allow instant userinteraction. The userinteraction is successfully evaluated on DBPedia, which is a large and noisy dataset. n parallel to the continuous development of the hypertext Web, we are witnessing an explosion of structured data published on the Web and leading to the emergence of a “Web of Data.” Companies like Google,...
