Rule-based systems process event streams and trigger actions according to pre-defined rule-sets. Over the last three decades, such systems have been widely used in businesses, governments and organisations. However, with today's need to process larger event streams such as events produced in Internet of Things (IoT), current rule-based systems face serious challenges in terms of speed, scalability...
Rule engine, which acknowledges facts and draws conclusions by repeatedly matching facts with rules, is a good way of knowledge representation and inference. However, because of its low computational efficiency and the limitation of single machine's capacity, it cannot deal well with big data. As traditional MapReduce architecture can only address this problem in certain conditions, we have made some...
In order to quickly response to changes in requirements or business rules, rule-based software development has been introduced to separate the business rules from the application code. Rule engine is adopted to achieve this aim and makes the business rules as an independent part. Business rules can be modified without affecting to the application, thus cost, time and effort in requirement analysis,...
Nowadays different sectors such as transport companies or public safety and emergency forces have great demand in mobile communications. In general, this area raises complex scenarios, where different access networks can be used, based on high-level administrative parameters (cost, geographic location). The use of different access networks could bring advantages in terms of availability and quality...
RFID technology has advanced a lot in recent years. In order for enterprises to be competitive, an increasing number have integrated the technology into their operations. Most RFID middleware providers focus on how to shield the bottom device-level heterogeneity to accelerate the application and deployment of this technology. They always concentrate on collecting RFID events to generate standard application-level...
Service Oriented Computing (SOC) is the fast emerging successor of the Object Oriented Computing design paradigm. Web Services technology, which is considered as an implementation of the SOC model, has had an incredible acceptance but tumultuous growth. This apparent chaos is due to its inherent lack of flexible cooperation strategies, generic service model and weak semantic description, mainly when...
RFID technology has advanced a lot in recent years. In order for enterprises to be competitive, an increasing number have integrated the technology into their operations. The prime challenge for RFID middleware is not to shield the bottom device-level heterogeneity but to accelerate the integration with legacy system and application in a complex scenario. In this paper, we introduce a distributed...
The bloom of Internet and the convenience of e-Commerce bring a lot of demands of Internet booking applications. There are two challenges in Internet Booking Applications: high volume concurrent processing and complex business processing. Facing these two challenges, we designed an extensible framework for Internet booking applications, which includes an Internet Booking Engine, a rule engine, and...
