During the last decade, the international community has been interested in the processes of publication and refinement of Knowledge Graphs (KGs) through initiatives such as the Web of Data. A multitude of methods and systems have been developed to address issues related to the acquisition, publication and exploitation of KGs. In particular, considerable progress has been made in the construction and the enrichment of KGs: ontology matching, data integration, fact prediction and validation. This happened thanks to the use of techniques developed in the fields of knowledge representation, reasoning and machine learning. With these advances, more and more industrial applications are now able to produce and process KGs. However, the produced KGs are complex and evolving, which open several new issues.
In this workshop, we seek contributions describing methods and uses-cases that rely on the application of reasoning and machine learning on complex, uncertain and evolving knowledge graphs. These contributions can be applied to different domains such as smart cities, smart health, smart farming, digital humanities and automation of business processes.
The workshop will cover topics around different types of reasoning and complex data treatment:
hybridization of symbolic and machine learning methods
reasoning in constrained environments
reasoning with uncertainty
reasoning with incompleteness
reasoning on large volumes of data
reasoning under open / closed world assumptions
reasoning for privacy (data access policy, anonymization, rewriting requests, etc.)
The workshop will be organized in two sessions of 90 minutes. A first session will be dedicated to several keynote speakers who are leaders in the domain of reasoning on complex and evolving Knowledge Graph. In a second session, a panel discussion will be organized with different actors from industry and academia. We invite any people interested to be part of the panel to send an email to the organizing committee (email@example.com ,firstname.lastname@example.org, email@example.com) in order to present themselves and their topics of interest.
The objectives of this workshop will be to provide a platform to discuss what has been achieved so far and what are the future challenges for reasoning on KGs.
