Our paper on extracting drug-drug interaction (DDI) from the literature has been accepted for publication in Bioinformatics. This paper focuses on using heterogeneous drug-related domain information for DDI relation extraction. Especially, we have created a large-scale knowledge graph covering drug-related information and learned embeddings of the nodes and links in order to obtain embedding vectors of various pieces of domain information in a single vector space, which is very important. Then, we use the pretrained embedding representations as external knowledge for neural DDI extraction from the literature.
This is a typical example of symbolic-neural learning (or neuro-symbolic learning), which we have been promoting in a series of International Workshops on Symbolic-Neural Learning since 2017.
