- Abstract: Knowledge graph (KG) entity typing aims at inferring possible missing entity
type instances in KG, which is a very significant but still under-explored
subtask of knowledge graph completion. In this paper, we propose a novel
approach for KG entity typing which is trained by jointly utilizing local
typing knowledge from existing entity type assertions and global triple
knowledge from KGs. Specifically, we present two distinct knowledge-driven
effective mechanisms of entity type inference. Accordingly, we build two novel
embedding models to realize the mechanisms. Afterward, a joint model with them
is used to infer missing entity type instances, which favors inferences that
agree with both entity type instances and triple knowledge in KGs. Experimental
results on two real-world datasets (Freebase and YAGO) demonstrate the
effectiveness of our proposed mechanisms and models for improving KG entity
typing. The source code and data of this paper can be obtained from:

We study the task of seed-guided fine-grained entity typing in science and engineering domains.
We propose SEType which first enriches the weak supervision by finding more entities for each seen type from an unlabeled corpus.
It then matches the enriched entities to unlabeled text to get pseudo-labeled samples and trains a textual entailment model that can make inferences for both seen and unseen types.

An empirical observation is that the head and tail entities connected by the same relation often share similar semantic attributes.

By enforcing the entities' embeddings close to their associated prototypes' embeddings, our approach can effectively encourage the global semantic similarities of entities.

Open Knowledge Graphs (such as DBpedia, Wikidata, YAGO) have been recognized as the backbone of diverse applications in the field of data mining and information retrieval.
Most of these KGs are mostly created either via an automated information extraction from snapshots or information accumulation provided by the users or using Wikipedias.
It has been observed that the type information of these KGs is often noisy, incomplete, and incorrect.
A multi-label classification approach is proposed in this work for entity typing using KG embeddings.
