Although CEP operators involve location specific attributes, state of the art systems are heavily constrained in detecting situations where the interest in a situation changes depending on the consumer's location, e. g., with the movement of mobile devices.\u0000 This paper adopts the concept of range queries to CEP systems. We propose a mobility-aware event delivery semantics and present a corresponding execution model, which accounts for mobility driven selection of primary event streams to the CEP system. By utilizing the properties of this execution model, we derive an algorithm that establishes low cost and coordinated reconfiguration of CEP operators in a distributed system. The algorithm minimizes the amount of information that needs to be streamed between operators and avoids additional delays as a result of a reconfiguration of CEP operators. We present an analysis of the algorithm's properties and evaluate the efficiency of the proposed reconfiguration algorithm.","PeriodicalId":92123,"journal":{"name":"Proceedings of the ...

However, event-based systems are tightly coupled, via event subscriptions and patterns, to the semantics of the underlying event schema and values. The high degree of semantic heterogeneity of events in large and open deployments such as smart cities and the sensor web makes it difficult to develop and maintain event-based systems. In order to address semantic coupling within event-based systems, we propose vocabulary free subscriptions together with the use of approximate semantic matching of events. This paper examines the requirement of event semantic decoupling and discusses approximate semantic event matching and the consequences it implies for event processing systems. We introduce a semantic event matcher and evaluate the suitability of an approximate hybrid matcher based on both thesauri-based and distributional semantics-based similarity and relatedness measures. The matcher is evaluated over a structured representation of Wikipedia and Freebase events. Initial evaluations show that the approach matches events with a maximal combined precision-recall F1 score of 75.89% on average in all experiments with a subscription set of 7 subscriptions. The evaluation shows how a hybrid approach to semantic event matching outperforms a single similarity measure approach.","PeriodicalId":92123,"journal":{"name":"Proceedings of the ...

This structured representation provides a simple yet powerful paradigm for building large-scale, distributed, high-performance applications. However, there are many tasks that require sharing data across operators, and across operators and the runtime using a less structured mechanism than point-to-point data flows. Examples include updating control variables, sending notifications, collecting metrics, building collective models, etc. In this paper we describe CAPSULE, which fills this gap. CAPSULE is a code generation and runtime framework that offers an easy to use and highly flexible framework for developers to realize shared variables (CAPSULE term for shared state) by specifying a data structure (at the programming-language level), and a few associated configuration parameters that qualify the expected usage scenario. Besides the easy of use and flexibility, CAPSULE offers the following important benefits: (1) Custom Code Generation - CAPSULE makes use of user-specified configuration parameters and information from the runtime to generate shared variable servers that are tailored for the specific usage scenario, (2) Composability - CAPSULE supports deployment time composition of the shared variable servers to achieve desired levels of scalability, performance and fault-tolerance, and (3) Extensibility - CAPSULE provides simple interfaces for extending the CAPSULE framework with more protocols, transports, caching mechanisms, etc. We describe the motivation for CAPSULE and its design, report on its implementation status, and then present experimental results.","PeriodicalId":92123,"journal":{"name":"Proceedings of the ...

However, classical Publish/Subscribe is not suitable for some emerging IoT applications such as smart grid, transportation and sensor/actuator applications due to its lack of QoS capability.\u0000 To meet the requirements for QoS in IoT message delivery, in this paper we propose the first Publish/Subscribe message broker with the ability to actively schedule computation resources to guarantee QoS requirements. We abstract the message matching algorithm into a task graph to express the data flow, forming a task-based stream matching framework. Based on the framework, we explore a message dispatching algorithm called Smart Dispatch and a task scheduling algorithm called DFGS to guarantee different QoS requirements.\u0000 Experiments show that, the QoS-aware system can support more than 10x throughput than QoS-ignorant systems in representative Smart Grid cases. Also, our system shows near-linear scalability on a commodity multi-core machine.","PeriodicalId":92123,"journal":{"name":"Proceedings of the ...

As measurement methods converge across different types of media, the online/offline measurement divide will diminish. Television is one such medium that has traditionally required offline measurements. Advertisers are, for the most part, still accepting predictions and historical behaviors rather than current facts. Despite the limited accountability, yearly spendings on television advertisements are still much higher than for any other medium, and rising.\u0000 In this paper, we present AdScorer, a scoring system for television advertisements. Our system is based on event stream processing techniques, and can compute scores for advertisements in near real-time based on channel change events from viewer set-top boxes. Our results show that AdScorer is capable of delivering detailed scores on a per-advertisement spot basis for a whole block of commercials, immediately after the commercial break has ended. The scores include regional breakdowns with viewer numbers and shares for each geographical region of Norway as well as national scores. Our evaluation of AdScorer demonstrates that it is capable of scoring numerous channels simultaneously. In our experiments, we used one machine to analyze five channels, but our system can easily scale to support hundres of channels by adding more machines.","PeriodicalId":92123,"journal":{"name":"Proceedings of the ...
