“…Some questions to ask when determining context is who will be using it, why, when, where, and what. It also consists of more specific aspects such as [19] location, time, temperature, even users emotions and preferences; these can be classified as scalar, vector, or abstract values. Selecting certain factors such as platform, will eliminate a lot of context of use issues; however, when considering IoT, most cases will not be platform dependent.…”

“…Cell phones being completely context aware would 3 EAI Endorsed Transactions on Internet of Things 01 2018 -03 2018 | Volume 4 | Issue 14 | e3 require sensors, and RFID tags. This would allow phones to be aware of locations and other information [19], which will limit the amount of interaction between the user and device. Context can also be used in terms of service contracts which is responsible for the fulfillment of agreed upon conditions.…”

EAI Endorsed Trans IoT

A large number of IoT platforms have been introduced in the last few years. The major issue with available platforms is that they view Things as private property. But this view is short sighted. A Thing should be viewed as a service or a functionality provider. The Thing owner should be able to publish Thing information and make it public. On the other hand, Thing requesters should be able to discover available Things. Our research is concerned with introducing an architecture that supports the publication and discovery of Things. This architecture will enable Thing owners to publish Thing specification and Thing requesters to find Things that best matches their needs. The main contribution of this paper is an SOA Context-aware Architecture for the publication and discovery of Things. This paper formally defines an architecture for Things and queries. Also, this paper presents two XML languages that supports the publication and query of Things.

“…The Jingling Genies project aims to grow knowledge and competencies at three levels: Interaction in globalized research, IT frameworks for context-sensitive services, and global supervision of PhD students [8]. The object of the globalized research in the Jingling Genies project is the development of theories and implementation of a framework for context-sensitive services [12]. This framework will consider the notion of context as a prime factor for providing trustworthy, useful and pervasive interaction with the user via mobile and generally pervasive units.…”

This showcase paper describes the Global Interaction Research Initiative-GIRI-recently inaugurated at the IT University of Copenhagen. It presents the motivation for this initiative, namely that the use of information technology is the core enabling factor for global collaboration and business. We argue that there is a fundamental need for understanding and providing next generation technologies for this ultra large-scale interaction paradigm. GIRI is organized around a set of research themes and projects, focusing on different application areas. Themes and projects are loosely coupled in the sense that each research project is defined in its own right with a specific set of challenges, vision, approach, partners, and funding scheme. At the time of writing, GIRI has 3 research themes and are hosting 6 projects, but these numbers are expected to increase as GIRI grows. GIRI is an open research initiative, and we invite other researchers to join.

“…In the development of SOA technology, our previous work [6] has presented the necessity of adopting context awareness techniques to service discovery and selection to fulfill the ever-growing demand of intelligent and user-centered service execution. Context awareness [1] originated as a term from ubiquitous computing or pervasive computing which sought to deal with continuous changes in the environment.…”

“…Thus a formal method is required. Dynamic Description Logic (DDL) [3] is adopted in this paper, since it is suitable for behavior formalization and inference, and it is based on Description Logic, which is commonly adopted as the logic foundation of ontology language standards, such as OWL [13], which is used to model context environment in our previous work [6] to provide the features of semantics description and knowledge sharing. However, when applied in context-awareness domain, the satiability-checking algorithm in DDL needs to be extended, since its Open World Assumption in essence restricts the expressiveness of preconditions in contextual behavior.…”

Service composition is one of the most important features of Service-Oriented Architecture (SOA), where it is imperative to automatically adapting changing context in the environment. This paper adopts context-awareness to service composition to construct SOA based systems/applications where contexts are behavior-integrated, user-centered and changing-adaptable. An overall framework of a context agent is established, which consists of behavior interpreter, ontology context repository, inference engine, contexture behavior sequence planner and evaluation repository. We formalize behaviors of context entity and services, and take them into consideration in behaviorplanning based service composition. An ontology model of context environment is built to describe context semantic in order to enable knowledge sharing. The predictability and controllability of context entities are addressed and corresponding evaluation mechanism and planning algorithm are proposed. Dynamic Description Logic is applied in contextual behavior sequence decision, and its satiability-checking algorithm is extended to enhance the constraining power of pre-conditions in a contextual behavior.
