The International Semantic Web Conference, to be held in Vienna in late October 2017, hosts an annual challenge that aims to promote the use of innovative and new approaches to creation and use of the semantic web. This year’s challenge will focus on knowledge graphs. Both public and privately owned, knowledge graphs are currently among the most prominent implementations of Semantic Web technologies.

This year’s Semantic Web Challenge is centered around two important tasks for building large-scale knowledge graphs:

Knowledge graph population. Given the name and type of a subject entity, (e.g., a company) and a relation, (e.g., CEO) participants are expected to provide the value(s) for the relation. Knowledge graph validation. Given a statement about an entity, e.g., the CEO of a company, participants are expected to provide an assessment about the correctness of the statement. For both tasks, users may use a portion of the knowledge graph for training. Furthermore, arbitrary sources (e.g., external datasets, Web pages, etc.) may be used as input.

Participants may choose to participate in one or both tasks. The evaluation of challenge participants will be carried out on the Knowledge Graph owned by Thomson Reuters (TR). The KG has a public and a private part; the public part can be used for building and training the candidate systems, the private part will be used for evaluation.
