In a service-oriented environment, heterogeneous data from distributed data archiving centers and various geo-processing services are chained together dynamically to generate on-demand data products. Creating an executable service chain requires detailed specification of metadata for data sets and service instances. Using metadata tracking, semantics-enabled metadata are generated and propagated through...
In distributed image mining using Web services, Web services implement individual mining algorithms. These services, together with those services providing data and data preprocessing functions, must be chained together dynamically to solve complex real world problems in mining applications. Service composition, the process of creating the service chain, can be divided into three phases: process modeling,...
