Foreword

The problem of search in Web services has been attracting the attention of researchers over the last decade. The reason for this is that as service technology evolves and as more services become available (and even more now with the advent of cloud computing) it becomes important to be able to locate the service that meets our needs within a large and sometimes dense cloud of offering. Many, often “spot” proposals have been put forward to address the problem and several standards have been defined, but none of these has been effective or is now accepted as the way to perform service search. This excellent book looks at the search problem from a broader perspective. Instead of narrowing down on a specific aspect or subproblem of service search, it dissects and analyzes the fundamental problems in search and presents concrete, applicable solutions as well as the theoretical foundations behind them. In particular, Yu and Bouguettaya define the notion and the characteristics of a Web Services Management System, which is the service analogous of a DBMS. They define why a WSMS is needed, and what makes it similar to and different from a DBMS. They specify a service model and a service algebra for querying Web services. All these aspects denote a rigorous and holistic approach to the problem which not only supports the search techniques provided in the book but that can be used as an underlying framework for res
