WCFA (Web service interface control flow automata) is enhanced by allowing pre/post-conditions for certain Web service invocations to be declared. The formal definition of WCFA is given. Global behaviors of web service compositions (described by a set of WCFA) are captured by ARG (abstract reachability graph), in which each control point is equipped with a state formula and a call stack. The algorithm...
Internet brings more flexibility and possibilities to software. How to develop and maintain the software conveniently and easily is a big challenge for the developers of Internet applications. The purpose of this paper is to create a systemic framework for object oriented design (OOD) and map between the program and the reality. This paper investigates the things, relations and interactions between...
We use WCFA (Web Service Interface Control Flow Automata) to model web service interfaces. Global behaviors of web service compositions are captured by abstract reachability graph(ARG). A polynomial time algorithm for the construction of ARG is presented. The algorithm uses a reachability analysis to verify both safety and call stack inspection properties. Both kinds of properties are expressed by...
Most of the current search engines focus on the content-based searching; therefore, they require the users to input accurate query terms. Unfortunately, most people would like to input just a few words when doing the search and the words themselves might have diverse meanings, which badly decrease the searching performance. The previous automatic query expansion algorithms usually use the documents...
With the rapid development of WWW, grid and IPv6, more and more collaborative science and technology research systems and applications have been built on Internet in many countries. SOA and Web2.0 bring new opportunities for collaboration in scientific research. We construct a digital collaborative R&D Platform for TNList (Tsinghua National Library for Information Science and Technology). This...
