A person ontology comprising concepts, attributes and relationships of people has a number of applications in data protection, didentification, population of knowledge graphs for business intelligence and fraud prevention.

The underlying idea is to frame the task of triple classification as a debate game between two reinforcement learning agents which extract arguments -- paths in the knowledge graph -- with the goal to justify the fact being true (thesis) or the fact being false (antithesis), respectively.

An ontology to capture the essential entities and relations is presented, as well as the description of data sources, which can be used to populate innovation knowledge graphs.

Large-scale knowledge graphs (KGs) are shown to become more important in current information systems.

KNOWLEDGE GRAPH COMPLETION RELATIONAL REASONING ZERO-SHOT LEARNING

Based on this new perspective, we re-formulate scene graph generation as the inference of a bridge between the scene and commonsense graphs, where each entity or predicate instance in the scene graph has to be linked to its corresponding entity or predicate class in the commonsense graph.

We simplify the problem by making a plausible assumption that the tensor representation of a knowledge graph can be approximated by its low-rank tensor singular value decomposition, which is verified by our experiments.

Rules over a knowledge graph (KG) capture interpretable patterns in data and can be used for KG cleaning and completion.

TransINT maps set of entities (tied by a relation) to continuous sets of vectors that are inclusion-ordered isomorphically to relation implications.

We show that by a proper selection of the loss function for training the TransE model, the main limitations of the model are mitigated.

We show popular embedding models are indeed uncalibrated.
