'Everything Personal, Not Just Business': Improving User Experience Through Rule-based Service Customization

The web services paradigm promises tremendous flexibility in the creation of rich composite services for enterprises and end-users. The flexibility and richness offers the possibility of highly customized, individualized services for the end user and hence revenue generating services for service providers (e.g. telecom network operators, ISPs, ASPs). But how can end-users (and enterprises) specify their preferences when a myriad of possibilities and potential circumstances need to be addressed? In this paper we advocate a solution based on policy management where user preferences are specified using high-level rules. This paper identifies the requirements for this kind of interpretation, and describes the Houdini prototype system (under development at Bell Labs) which offers a rich rule-based language and a framework that supports intuitive, forms-based provisioning interfaces.
