Abstract

Dataspaces are the collections of heterogeneous and partially unstructured data. It is difficult for the users to explore the data from varies data sources using a single schema. And the queries supposed should be allowed to specify varying degrees of structure, spanning keyword queries to more structure-aware queries. Utilizing give the model of heterogeneous data and the definitions of two mainly types of query on dataspaces, in this paper we propose an improved method which can suppose the flexibly query more efficiently.
