Through their planning processes, Bedfordshire CCG (BCCG) recognised the need to both change the services they commission and the way they commission services. They decided to take a whole systems approach to redesigning their Musculoskeletal care (MSK) service, which at the time represented the fourth highest area of spend but delivered a fragmented, variable and inequitable service for patients.

Service Oriented Architecture and Web Services provide an integration infrastructure for service workflow composition and execution. Many planning techniques can be facilitated to construct the service workflow at a building phase (planning), however, it is difficult and challenging to maintain the qualities of service workflow at execution phase, as the delayed response time, the limited throu...

Hierarchies are the most common structure used to understand the world better. In galaxies, for instance, multiple-star systems are organised in a hierarchical system. Then, governmental and company organisations are structured using a hierarchy, while the Internet, which is used on a daily basis, has a space of domain names arranged hierarchically. Since Artificial Intelligence (AI) planning p...

My PhD research is focused on Web Service Composition through the use of AI planning techniques, considering the domain as an inherently non-deterministic one. The main goal of my research is to build a system in which an end user will be able to search for suitable web services, add new ones, and create new composite ones either manually or automatically. As a practical example of the usefulne...

BACKGROUND Service user (patient) involvement in care planning is a principle enshrined by mental health policy yet often attracts criticism from patients and carers in practice. AIMS To examine how user-involved care planning is operationalised within mental health services and to establish where, how and why challenges to service user involvement occur. METHOD Systematic evidence synthesi...

A static approach is proposed to study secure composition of services. We extend the λ-calculus with primitives for selecting and invoking services that respect given security requirements. Security-critical code is enclosed in policy framings with a possibly nested, local scope. Policy framings enforce safety and liveness properties. The actual run-time behaviour of services is over-approximat...

This paper presents PORSCE II, an integrated system that performs automatic semantic web service composition through planning. In order to achieve that, an essential step is the translation of the web service composition problem into a planning problem. The planning problem is then solved using external domain-independent planning systems, and the solutions are visualized and evaluated. The sys...
