User behaviors in online social networks convey not only literal information but also one’s emotional attitudes towards the information. To compute this attitude, we define the concept of emotion role as the concentrated reflection of a user’s online ...

The aim of this article is to propose a new innovative grouping approach using the genetic algorithm (GA) to enhance the interaction and collaboration among peers by considering the complementary degree of students’ learning status and their social ...

The widespread adoption of the Internet of Things (IoT) has created a demand for ubiquitous connectivity of IoT devices into the Internet. While end-to-end connectivity for IoT requires in practice IPv6, a vast majority of nodes in Internet are only ...

A key success of a Web service is to appropriately design its interface to make it easy to consume and understand. In the context of service-oriented computing (SOC), the service’s interface is the main source of interaction with the consumers to reuse ...

We present a new spatio-temporal incentive-based approach to achieve a geographically balanced coverage of crowdsourced services. The proposed approach is based on a new spatio-temporal incentive model that considers multiple parameters including ...

The convergence of Internet of Things (IoT) and the Cloud has significantly facilitated the provision and management of services in large-scale applications, such as smart cities. With a huge number of IoT services accessible through clouds, it is very ...

The adoption of the Internet of Things (IoT) drastically witnesses an increase in different domains and contributes to the fast digitalization of the universe. Henceforth, next generation of IoT-based systems are set to become more complex to design and ...

The fog computing paradigm has drawn significant research interest as it focuses on bringing cloud-based services closer to Internet of Things (IoT) users in an efficient and timely manner. Most of the physical devices in the fog computing environment, ...

Internet-based Indoor Navigation Service-Oriented Architectures (IIN-SOA) organize signals collected by IoT-based devices to enable a wide range of novel applications indoors, where people spend 80--90% of their time. In this article, we study the ...

Adaptive Case Management (ACM) has emerged as a key BPM technology for supporting the unstructured business process. A key problem in ACM is that case schemas need to be changed to best fit the case at hand. Such changes are ad hoc, and may result in ...

A growing number of business process management systems is under development both in academia and in practice. These systems typically are based on modern system engineering principles, such as service-oriented architecture. At the same time, the advent ...

Business process improvement is an endless challenge for many organizations. As long as there is a process, it must be improved. Nowadays, improvement initiatives are driven by professionals. This is no longer practical because people cannot perceive ...

Knowledge-intensive Processes (KIPs) are processes whose execution is heavily dependent on knowledge workers performing various interconnected knowledge-intensive decision-making tasks. Among other characteristics, KIPs are usually non-repeatable, ...

Process mining techniques aim at analyzing records generated during the execution of a business process in order to provide insights on the actual performance of the process. Detecting concurrency relations between events is a fundamental primitive ...
