Abstract :
There are large demands for re-engineering human-oriented Web application systems for use as machine-oriented Web application systems, which are called Web services. This paper describes a framework named H2W, which can be used for constructing Web service wrappers from existing, multi-paged Web applications. H2Ws contribution is mainly for service extraction, rather than for the widely studied problem of data extraction. For the framework, we propose a page-transition-based decomposition model and a page access abstraction model with context propagation. With the proposed decomposition and abstraction, developers can flexibly compose a Web service wrapper of their intent by describing a simple workflow program incorporating the advantages of previous work on Web data extraction. We show three successful wrapper application examples with H2W for real world Web applications
