This volume contains lecture notes of the 14th Reasoning Web Summer School (RW 2018) held in
Esch-sur-Alzette Luxembourg in September 2018. The research areas of Semantic Web Linked
Data and Knowledge Graphs have recently received a lot of attention in academia and industry.
Since its inception in 2001 the Semantic Web has aimed at enriching the existing Web with
meta-data and processing methods so as to provide Web-based systems with intelligent
capabilities such as context awareness and decision support. The Semantic Web vision has been
driving many community efforts which have invested a lot of resources in developing
vocabularies and ontologies for annotating their resources semantically. Besides ontologies
rules have long been a central part of the Semantic Web framework and are available as one of
its fundamental representation tools with logic serving as a unifying foundation. Linked Data
is a related research area which studies how one can make RDF data available on the Web and
interconnect it with other data with the aim of increasing its value for everybody. Knowledge
Graphs have been shown useful not only for Web search (as demonstrated by Google Bing etc.)
but also in many application domains.
