Conceptual elevation of data in business process modeling was first formulated in 2003. The research community responded to this new idea enthusiastically. In the past decade, there have been numerous research activities concerning the interactions between business processes/activities and data in many aspects of business process management. Many of the advancements have or will have impacted on design/modeling,...
Among the most important and distinctive actionable knowledge are actionable behavioral rules (ABRs). To make ABRM a promising technique for security informatics, we develop new methodologies for it. We also conduct an experiment to validate our approach. The experimental results strongly suggest the validity of our approach.
The task abstraction and aggregation in a business process can help to (1) obtain customized descriptions of a business process for different users, and (2) derive user interfaces of a business process related to the participating users. This paper proposes an approach for task abstraction and aggregation of a business process based on a role-enriched business process model. For each user role, tasks...
Hierarchical time series (HTS) is a special class of multivariate time series where many related time series are organized in a hierarchical tree structure and they are consistent across hierarchy levels. HTS modeling is crucial and serves as the basis for business planning and management in many areas such as manufacturing inventory, energy and traffic management. However, due to machine failures,...

Business process (or workflow) management is vital in enterprise application systems. Current workflow management systems (WfMSs) do not provide a clear separation between execution management and data management, such a lack of separation causes serious difficulties in managing data consistency and process change. This paper argues for an "execution independence" principle of isolating...
An important omission in current development practice for business process (or workflow) management systems is modeling of data & access for a business process, including relationship of the process data and the persistent data in the underlying enterprise database(s). This paper develops and studies a new approach to modeling data for business processes: representing data used by a process as...
Trust and reputation of web services is usually established based on the historical information about past transactions or rating scores collected over a period of time. However, when a new web service joins a community, normally there is not much information to be relied on to evaluate its initial reputation. Therefore trust bootstrapping, the technique to establish trust for a web service based...
Business process (BP) can be supported by a large number of resources with evolving contents. In order to receive the support from these resources, the BP must satisfy the authorization policies of these resources. On the other hand, a BP also has its own authorization policies that users must satisfy in order to interact with the BP. Meanwhile, execution policies need to be applied to manage the...
Service composition is a technique to recompose various heterogeneous network services for a new business. A modern streaming media system may run multiple businesses. Their resources can easily be improperly distributed and under utilized. This paper studies service composition in the context of streaming media applications. A three-layer model is adopted to describe the system. The optimal service...
With the steady growth of Web services in recent years, service users are confronted with great difficulties in selecting suitable services from substantial functionally similar services in the complex service provisioning environment. Contradictions and incompatibilities arise during service selection in the design and maintenance of enterprize applications. To solve these problems, necessary relations...
Mashups, a new Web 2.0 technology provide the ability for easy creation of Web-Based applications by end-users. The uses of the mashups are often consumer related. In this paper we explore how mashups can be used in the enterprise area and hat the criteria for enterprise mashups are. We provide categories for the classification of enterprise mashups, and based upon a motivating example we go further...
Privacy in Web services is of great importance and a critical requirement for any business and non-business environments. The growth of Web services has been accompanied by sharing more and more user personal information with Web service providers between diverse and heterogeneous computing systems, which has raised concern about possible malicious or accidental unauthorized abuse of user information...
The adoption of Web service technologies in dynamic business applications such as on-demanding computing or highly reconfigurable virtual enterprises advocates for methods and tools for describing and managing non-functional aspects of services, e.g., the reliability, accessibility and accuracy of a service. These properties are referred as quality of service (QoS). Failing to accurately specify and...
