Query: Knowledge Graph Embedding in E-commerce Applications: Attentive
  Reasoning, Explanations, and Transferable Rules   Knowledge Graphs (KGs), representing facts as triples, have been widely
adopted in many applications. Reasoning tasks such as link prediction and rule
induction are important for the development of KGs. Knowledge Graph Embeddings
(KGEs) embedding entities and relations of a KG into continuous vector spaces,
have been proposed for these reasoning tasks and proven to be efficient and
robust. But the plausibility and feasibility of applying and deploying KGEs in
real-work applications has not been well-explored. In this paper, we discuss
and report our experiences of deploying KGEs in a real domain application:
e-commerce. We first identity three important desiderata for e-commerce KG
systems: 1) attentive reasoning, reasoning over a few target relations of more
concerns instead of all; 2) explanation, providing explanations for a
prediction to help both users and business operators understand why the
prediction is made; 3) transferable rules, generating reusable rules to
accelerate the deployment of a KG to new systems. While non existing KGE could
meet all these desiderata, we propose a novel one, an explainable knowledge
graph attention network that make prediction through modeling correlations
between triples rather than purely relying on its head entity, relation and
tail entity embeddings. It could automatically selects attentive triples for
prediction and records the contribution of them at the same time, from which
explanations could be easily provided and transferable rules could be
efficiently produced. We empirically show that our method is capable of meeting
all three desiderata in our e-commerce application and outperform typical
baselines on datasets from real domain applications.
