Mustafa, Faisal and McCluskey, T.L. (2009) Dynamic web services composition: current issues. International Conference on Computer Engineering and Technology, 2009. ICCET '08, 2. pp. 463-467.

A major area of recent web-related research
concerns automated web service composition. The strength of web services technology is the possibility of creating value-added services by combining existing ones to achieve customized tasks.
How to combine these services efficiently into an arrangement that is both functionally sound and architecturally realizable is a
very challenging topic that has founded a significant research area within computer science.
Our research contribution lies in the area of dynamic
composition services selection. We have started by collating and
analyzing current outstanding problems within the dynamic
composition area. To help explain the background to these
challenges we compare, firstly, the key components of distributed
computing technologies with web service composition.
implementation supplies its service description (WS Register),
and provides technical and business support to clients.
Then we
define the ‘execute ability’ problem - the key idea that
preconditions of web services must be satisfied before or during
composition. We discuss data distribution strategies among
services, how they can be used to overcome problems in dynamic
composition problems and how they relate to the quality of
service. Finally, we present our proposed framework model to
handle the process of web service composition and execution. We
propose that this framework eliminates the main problems as
discussed in the paper.
