Heterogeneity in RSP engines

We have several RDF Stream Processing engines• C-SPARQL, CQELS, SPARQLstream, EP-SPARQL...

Heterogeneity in • Languages• Features • Query models

Stream Reasoning techniques

Can we exploit the semantics in the stream to improve the processing?• Window management• Maintenance

Challenge 2: Techniques and methods for Stream Reasoning• J. Z. Pan (invited speaker): The Maze of Deletion in Stream

Reasoning• R. Yan, M. T. Greaves, W. P. Smith and D. L. McGuinness:

Stream Reasoning in applications

SR starts to be mature to be used in real use cases

However, new challenges are emerging• Modelling• Noise• Algorithms and scalability

Challenge 3: SR in real settings• F. Lecue (invited speaker): Ontology Stream Reasoning for

Diagnosis and Predictive Inference• P. Schneider, J. Parreira and T. Eiter: Towards Spatial

Ontology-Mediated Query Answering over Mobility Streams• H. Khrouf, B. Belabbess, L. Bihanic, G. Kepeklian and O.
