TAGAT: Type-Aware Graph Attention neTworks for reasoning over knowledge graphs

作者:

Highlights:

• A reasoning model over KG based on graph attention networks is proposed.

• The model jointly embeds semantic, neighborhood and entity type information.

• Multi-layer attention mechanism considering type is applied to learn neighborhood.

• Type is integrated into embedding as constraints conforming to human intuition.

• The embedding space has type-related interpretation by means of embedding types.
