报告摘要:

Knowledge graph (KG) is a large scale semantic network consisting of entities/concepts as well as the semantic relationships among them, which could be considered as a concise version of Semantic Web. Recently KG is emerging as a hot topic of knowledge discovery and management under artificial intelligence, facilitating semantic computing. Embedding is an effective way for dimensionality reduction and latent semantic representation, which is able to be applied in high dimensional space context such as network and graph. In this seminar, I am going to present our recent researches about combining KG and embedding for recommender systems, to address the inherent research challenges in recommender systems, such as cold-start and sparsity.
