Explainable Reasoning over Knowledge Graphs for Recommendation

Incorporating knowledge graphs into recommender systems has attracted increasing attention in recent years. By exploring the interlinks within a knowledge graph, the connectivity between users and items can be discovered as paths, which provide rich and complementary information to user-item interactions. Such connectivity not only reveals the semantics of entities and relations, but also helps to comprehend a user’s interest. However, existing efforts have not fully explored this connectivity to infer user preferences, especially in terms of modeling the sequential dependencies within and holistic semantics of a path. We have developed a new model named Knowledge-aware Path Recurrent Network (KPRN) to exploit knowledge graphs for recommendation.

Faster E-commerce Search

The search engine plays an essential role in e-Commerce: it connects the user's need with a set of relevant items based on a query. This is not a simple task; millions of queries per second need to be processed over possibly billions of items, and it is expected that every query will be executed in just a few hundred milliseconds using limited resources.
