Goal models as run-time entities in context-aware systems

Content Provider ACM Digital Library
Author Mussbacher, Gunter Petriu, Dorina Vrbaski, Mira Amyot, Daniel
Abstract The strength of goal models is their ability to assess candidate solutions against high level criteria for many stakeholders, allowing system-wide trade-offs to be performed. We argue that, in a context-aware system, reasoning based on goal models can complement standard rule-based reasoning engines for decision making without involving explicit interaction with the user. While rule-based systems excel in filtering out unsuitable solutions based on clear criteria, it is difficult to rank suitable solutions based on vague, qualitative criteria of stakeholders with a rule-based approach. The User Requirements Notation (URN) is a goal-based and scenario-based requirements modeling language that has been applied to many different domains, from reactive systems to telecommunication standards to business processes. For context-aware systems, URN's workflow notation can describe the overall behavior of a context-aware system and URN's goal models can further enhance reasoning about contextual situations. While URN already supports some of the interactions between workflow and goal models required for the specification of context-aware systems, it does not yet fully support the modeling, design-time simulation, and run-time execution of a context-aware system based on its URN model. This paper (i) introduces such a modeling, simulation, and execution environment, (ii) discusses three architectural solutions for combined rule-based and goal-oriented reasoning, and (iii) reports on a URN profile that describes a domain-specific language for context-aware reasoning using goal-orientation with the help of an example application from the health care domain.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
