Modeling Relational Data with Graph Convolutional Networks

17 Mar 2017tkipf/gae

Knowledge graphs enable a wide variety of applications, including question answering and information retrieval. We demonstrate the effectiveness of R-GCNs as a stand-alone model for entity classification.

Convolutional 2D Knowledge Graph Embeddings

5 Jul 2017TimDettmers/ConvE

In this work, we introduce ConvE, a multi-layer convolutional network model for link prediction, and report state-of-the-art results for several established datasets. We also show that the model is highly parameter efficient, yielding the same performance as DistMult and R-GCN with 8x and 17x fewer parameters.

DeepPath: A Reinforcement Learning Method for Knowledge Graph Reasoning

EMNLP 2017 xwhan/DeepPath

We study the problem of learning to reason in large scale knowledge graphs (KGs). More specifically, we describe a novel reinforcement learning framework for learning multi-hop relational paths: we use a policy-based agent with continuous states based on knowledge graph embeddings, which reasons in a KG vector space by sampling the most promising relation to extend its path.

Knowledge Graph Completion via Complex Tensor Factorization

22 Feb 2017ttrouill/complex

In statistical relational learning, knowledge graph completion deals with automatically understanding the structure of large knowledge graphs---labeled directed graphs---and predicting missing relationships---labeled edges. State-of-the-art embedding models propose different trade-offs between modeling expressiveness, and time and space complexity.

Holographic Embeddings of Knowledge Graphs

16 Oct 2015mnick/holographic-embeddings

Learning embeddings of entities and relations is an efficient and versatile method to perform machine learning on relational data such as knowledge graphs. In this work, we propose holographic embeddings (HolE) to learn compositional vector space representations of entire knowledge graphs.

KBGAN: Adversarial Learning for Knowledge Graph Embeddings

HLT 2018 cai-lw/KBGAN

Because knowledge graphs typically only contain positive facts, sampling useful negative training examples is a non-trivial task. This framework is independent of the concrete form of generator and discriminator, and therefore can utilize a wide variety of knowledge graph embedding models as its building blocks.

Learning Deep Generative Models of Graphs

ICLR 2018 snap-stanford/GraphRNN

Graphs are fundamental data structures which concisely capture the relational structure in many important real-world domains, such as knowledge graphs, physical and social interactions, language, and chemistry. Here we introduce a powerful new approach for learning generative models over graphs, which can capture both their structure and attributes.

One-Shot Relational Learning for Knowledge Graphs

EMNLP 2018 xwhan/One-shot-Relational-Learning

Knowledge graphs (KGs) are the key components of various natural language processing applications. To further expand KGs' coverage, previous studies on knowledge graph completion usually require a large number of training instances for each relation.

Learning Sequence Encoders for Temporal Knowledge Graph Completion

EMNLP 2018 nle-ml/mmkb

In line with previous work on static knowledge graphs, we propose to address this problem by learning latent entity and relation type representations. The proposed approach is shown to be robust to common challenges in real-world KGs: the sparsity and heterogeneity of temporal expressions.

Representation Learning for Visual-Relational Knowledge Graphs

7 Sep 2017nle-ml/mmkb

A visual-relational knowledge graph (KG) is a multi-relational graph whose entities are associated with images. Both the prediction of relations between unseen images and multi-relational image retrieval can be formulated as query types in a visual-relational KG.
