The minority information resources' construction is an important part of national information construction in China. The heterogeneous distributed data semantic integration technology within cloud computing platform, mainly focus on how to use the machine automatically analyzing, understanding and handling of user needs and heterogeneous information. In this paper, the methodology of the semantic integration and dynamic management of heterogeneous distributed data is introduced firstly. And then how to build the semantic ontology for heterogeneous information are illustrated. The technology can find the data related with \"Cloud application\", and then it can convert the chaotic data source to an orderly, easy-to-use source of information.
