The 47 revised full papers presented together with three invited talks were carefully reviewed
and selected from 204 submissions. This program was completed by a demonstration and poster
session in which researchers had the chance to present their latest results and advances in
the form of live demos. In addition the PhD Symposium program included 10 contributions
selected out of 21 submissions. The core tracks of the research conference were complemented
with new tracks focusing on linked data machine learning mobile web sensors and semantic
streams natural language processing and information retrieval reasoning semantic data
management big data and scalability services APIs processes and cloud computing smart
cities urban and geospatial data trust and privacy and vocabularies schemas and
