Context-aware services enable users to interact with their environment in more useful ways. Rule-based systems are used for base vehicles for context-aware services due to their powerful capability to represent situations and corresponding actions to be performed. Usually, environments where context-aware services are applied are not static but have somewhat dynamic features. This paper describ...

Emerging ubiquitous computing network is expected to consist of a variety of heterogeneous and distributed devices. While web services technology is increasingly being considered as a promising solution to support the inter-operability between such heterogeneous devices via well-defined protocol, currently there is no effective framework reported in the literature that can address the problem o...

Changes in the information age have induced necessity for a more efficient and effective self-decision-making requirement. A method of extracting constructing naval operations decision-making rules based on scenario analysis is proposed. The template specifications Event Condition Action (ECA) are defined, consistency detection ECA SWRL logical relationships state transitions operational proces...

The recent development of network technology has enabled us to access various information sources easily, and their integration has been studied intensively by the data engineering research community. Although technological advancement has made it possible to integrate existing heterogeneous information sources, we still have to deal with information sources of a new kind—dissemination-based in...

Cellular automata (CA) have been utilized for decades as discrete models of many physical, mathematical, chemical, biological, and computing systems. The most widely known form of CA, the elementary cellular automaton (ECA), has been studied in particular due to its simple form and versatility. However, these dynamic computation systems possess evolutionary rules dependent on a neighborhood of ...

The Internet of Things (IoT), with its plethora of smart objects and technologies, allows to realize smart environments in several scenarios. However, the existing solutions are strictly intended for specific applications and their customization is often limited to what developers have considered at the design and implementation time. So, the integration of new functionalities requires signific...

This paper focuses on dimensions characterizing the execution of global ECA rules within multi-database systems (MDBS). The MDBS speci cities that a ect rule execution are identi ed and integrated in the dimensions currently used to characterize the active rule behavior. As a result, we propose a rule execution taxonomy for global rules. It is composed of dimensions structured in three levels t...

Event processing rules may be prescribed in many different ways, including by finite state machines, graphical methods, ECA (event-conditionaction) rules or reactive rules that are triggered by event patterns. In this paper, we present a model for defining event relationships for event processing rules. We propose a so-called correlation set allowing users to graphically model the event correla...
