Survey: When semantics meet crowdsourcing to enhance big data variety

Houssein Dhayne, Rima Kilany Chamoun, Maria Sokhn
2018 2018 IEEE Middle East and North Africa Communications Conference (MENACOMM)  
Semantic technologies, as a means of integration and coordination of heterogeneous systems, may help big data to manage terminology and relationships to link various data from different data sources.  ...  Crowdsourcing platforms have the potential to integrate (entity matching, entity resolution) and analyze (sentiment analysis, image recognition) heterogeneous data sources when in some cases these integration  ...  crowdsourcing would improve the quality of integrated data.  ...

DEMO: Managing the Provenance of Crowdsourced Disruption Reports [chapter]

Milan Markovic, Peter Edwards, David Corsar, Jeff Z. Pan
2012 Lecture Notes in Computer Science  
We are exploring the potential role of provenance to facilitate processes such as quality assessment within such systems.  ...  In this demo we present an application for managing traffic disruption reports generated by the crowd, and outline the technologies used to integrate provenance, linked data, and streams.  ...  A crowdsourcing application able to gather, manage, and assess disruption reports would provide an obvious solution.  ...
