Building mobile context‐aware systems is inherently complex and non‐trivial task. It consists of several phases starting from acquisition of context, through modeling to execution of contextual models. Today, such systems are mostly implemented on mobile platforms, that introduce specific requirements, such as intelligibility, robustness, privacy, and efficiency. Over the last decade, along with the...
Business Process models help to visualize the processes of an organization. There are open-source process execution engines that provide the environments for enacting process models. However, they lack semantization capabilities. In this paper, an overview of Business Process semantization techniques is provided. Moreover, we discuss the common architecture of the selected open-source process execution...
Knowledge management in business information systems often requires a unified dictionary of business concepts, that allows for a transparent integration of such systems. Thanks to it sharing the conceptualization between users becomes possible, and better decision support facilities can be provided. The Prosecco project is a research and development project aims to address the needs and constraints...
In this paper we introduce a new method to incorporate the user as an additional information source for the purpose of indoor localization. Therefore, the user is interrogated about certain characteristics in his/her environment. The questions are generated by a knowledge-based system built on ontologies. We provide a new statistical model to evaluate the user's answer and integrate it into the particle...
