Knowledge graph learning plays a critical role in integrating domain specific
knowledge bases when deploying machine learning and data mining models in
practice. Existing methods on knowledge graph learning primarily focus on
modeling the relations among entities as translations among the relations and
entities, and many of these methods are not able to handle zero-shot problems,
when new entities emerge. In this paper, we present a new convolutional neural
network (CNN)-based dual-chain model. Different from translation based methods,
in our model, interactions among relations and entities are directly captured
via CNN over their embeddings. Moreover, a secondary chain of learning is
conducted simultaneously to incorporate additional information and to enable
better performance. We also present an extension of this model, which
incorporates descriptions of entities and learns a second set of entity
embeddings from the descriptions. As a result, the extended model is able to
effectively handle zero-shot problems. We conducted comprehensive experiments,
comparing our methods with 15 methods on 8 benchmark datasets. Extensive
experimental results demonstrate that our proposed methods achieve or
outperform the state-of-the-art results on knowledge graph learning, and
outperform other methods on zero-shot problems. In addition, our methods
applied to real-world biomedical data are able to produce results that conform
to expert domain knowledge.
