Streaming MASSIF Prototypes

Info

Streaming MASSIF Prototypes allows to easily create RDF Stream Processing (RSP) and Stream Reasoning (SR) applications. The GUI can be accessed on HTTP://localhost:90000/.

Demo Use Case

To demonstrate the features of Streaming MASSIF Prototypes we build an RSP application step-by-step that loads a traffic data stream from the City Bench benchmark. We will investigate the intermediate results to verify the various processing steps.

GOAL: detect when traffic is increasing from a high traffic count to a very high traffic count.

Demo step:

1. Define a Source to read the traffic stream (we will read it from file with a timeout of 1 second between events).
2. Investigate the data in the stream.
3. Map the data to the semantic model (we will use the SSN ontology).
4. As we are only interested in high to very high vehicle counts, we want to filter out any event that is not a vehicle count event and has a count below 10.
5. We want to abstract the high and very high vehicle count observations.
6. These abstractions can then be used to detect temporal patterns.
