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. H2W's contribution is mainly for service extraction, rather than for the widely studied problem of data extraction. For the framework, the authors 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.
