CKG 2018 - 1ST INTERNATIONAL WORKSHOP ON CONTEXTUALIZED KNOWLEDGE GRAPHS (CKG 2018)

This workshop is related to Contextualized Knowledge Graphs (CKGs), i.e., Knowledge Graphs where every fact can be associated with values in different contexts (e.g., provenance, time, location, or confidence). CKGs have been gaining importance in the recent years, from research initiatives in contextualized and Distributed Description Logics, annotation of statements in the Semantic Web, or Distributed Knowledge Repositories, to being a need in the creation of collaborative knowledge bases, such as Wikidata, where qualifiers and references can be attached to every statement. This workshop aims to serve as a gathering point for researchers and industry interested in CKGs to discuss current challenges and solutions, while at the same time raising awareness about this emerging topic to a more broader community. It addresses topics that range from foundational to practical topics: from logical models to encode the contextual annotations in the graph, or reasoning and querying with CKGs, to exploiting CKGs in applications such as query answering, data mining, or machine learning, as well as techniques to benchmark or improve the performance of contextual graphs management. The workshop will potentially serve as a kickstarter for the creation of a W3C working group on this topic.
