Abstract
ABSTRACTIn mobile environments, users often need to coordinate their actions with other users with regard to user-individual context information like current location when selecting suitable services for a process. Thereby, some users may prefer to conduct particular services together with certain other users. Such multi-user context-aware service selections could result in complex decision problems – making decision support for the participating users highly valuable or even necessary. To do so, we propose an optimisation-based service selection approach for multi-user context-aware processes. We also show how our approach provides decision support by evaluating its efficacy based on a real-world scenario.
Highlights
The tremendous advances in mobile technologies and the rise of mobile business over the last decade have led to a rapid growth of the service market (Statista, 2017)
Selecting services for processes in mobile environments like a tourism city day trip often results in a decision problem of high complexity as it is often necessary to coordinate the actions of multiple users as well as to consider context information
Context information can refer to the current location, daytime, and so on, or generally speaking ‘any information that can be used to characterize the situation of an entity1’ (Dey, 2001, p. 5)
Summary
The tremendous advances in mobile technologies and the rise of mobile business over the last decade have led to a rapid growth of the service market (Statista, 2017). Selecting services for processes in mobile environments like a tourism city day trip often results in a decision problem of high complexity as it is often necessary to coordinate the actions of multiple users as well as to consider context information. In this regard, context information can refer to the current location, daytime, and so on, or generally speaking ‘any information that can be used to characterize the situation of an entity1’ Preferencebased dependencies and users preferring (but not enforcing) to use certain services (or service objects) together with other users have not been addressed in literature so far
