Plan-Based Semantic Enrichment of Event Streams [chapter]

Kia Teymourian, Adrian Paschke
2014 Lecture Notes in Computer Science  
In this paper, we present an efficient technique for event stream enrichment by planning multi-step event enrichment and processing.  ...  The event enrichment is optimized to avoid unnecessary event stream enrichment without missing any complex events of interest.  ...  We propose an approach for knowledge-based event processing using semantic enrichment of event streams (section 2).  ...

Predicting Severity of Road Traffic Congestion Using Semantic Web Technologies [chapter]

Freddy Lécué, Robert Tucker, Veli Bicer, Pierpaolo Tommasi, Simone Tallevi-Diotallevi, Marco Sbodio
2014 Lecture Notes in Computer Science  
Our prototype of semantics-aware prediction, being used and experimented currently by traffic controllers in Dublin City Ireland, works efficiently with real, live and heterogeneous stream data.  ...  In particular we present a system which integrates numerous sensors (exposing heterogenous, exogenous and raw data streams such as weather information, road works, city events or incidents) to improve  ...  Diagnosis is based on semantic matching of events and a probabilistic model while prediction is based on stream auto-correlation, association mining.  ...

SEPP: Semantics-Based Management of Fast Data Streams

Dominik Riemer, Ljiljana Stojanovic, Nenad Stojanovic
2014 2014 IEEE 7th International Conference on Service-Oriented Computing and Applications  
In this paper, we propose a semantic model for the management of fast data streams using the concept of Semantic Event Processing Pipelines (SEPP).  ...  Increased volume of event streams as well as the demand for more complex real-time analytics require for execution of processing pipelines among heterogeneous event processing engines.  ...  [14] introduces a middleware for publishing semantic event streams. This approach requires semantically enriched data streams.  ...
