Abstract

One of the big challenges of using knowledge graphs for recommendations is how to capture the structured know-ledge of items and extract its semantic features. To solve this problem, this paper proposed a collaborative filtering recommendation algorithm based on knowledge graph embedding(KGECF). Firstly, it extracted the knowledge information related to items from the Freebase knowledge graph and linked with historical interactive items to construct knowledge subgraphs. Then it obtained the representation of entities and relations in the sub-graph using the Xavier-TransR method based on TransR. This paper designed an end-to-end joint learning model to embed structured information and historical preference information into a unified vector space. Finally, it used the collaborative filtering method to further calculate these vectors to generate an accurate re-commendation list. Experimental results on two public datasets MovieLens-1M and Amazon-book show that the proposed algorithm is superior to the baseline algorithms in terms of precision, recall, F1 value and NDCG metrics. It means that the above method can integrate large-scale structured and unstructured data, while obtaining high precision recommendation results.
