rsplab's Introduction

RSP Lab

Abstract

In Stream Reasoning (SR), empirical research on RDF Stream Processing (RSP) is attracting a growing attention. The SR community proposed methodologies and benchmarks to investigate the RSP solution space and improve existing approaches. In this paper, we present \rsplab, an infrastructure that reduces the effort required to design and execute reproducible experiments as well as share their results. RSPlab integrates two existing RSP benchmarks (LSBench and CityBench) and two RSP engines (C-SPARQL engine and CQELS).
It provides a programmatic environment to: deploy in the cloud RDF Streams and RSP engines, interact with them using TripleWave and RSP Services, and continuously monitor their performances and collect statistics. RSPlab is released as open-source under an Apache 2.0 license.

RSP Lab aims at being the a full stack development environment for RSP Engines. To this extent, we started by realizing a platform that will support research

Included Benchmarks:

Information on how to set up and run existing experiments can be found in the wiki.

test the scripts against pollution. Mapping should be similar to what did for the traffic.

Broken links

Hello there,
I'm trying to setup the project, but I've found that most of the links in the wiki are broken. Can you tell me where are the instructions to install the project from scratch?

Experiments 10 is not working

CSPARQL fails to register the query for experiments 10.

Registering the following query:

select ?obId1 ?obId2 ?lat1 ?lon1 ?lat2 ?lon2 ?v1 ?v2 ((?v1+?v2) as ?sumOfAPI)
from stream http://www.insight-centre.org/dataset/SampleEventService#AarhusPollutionData201399 [range 3s step 1s]
from stream http://www.insight-centre.org/dataset/SampleEventService#AarhusPollutionData184892 [range 3s step 1s]

throws the following exception:
