Bio

I received my Ph.D. degree in Artificial Intelligence from University of Chinese Academy of Sciences (UCAS), under the supervision of Prof. Ji Xiang in 2020. During my Ph.D., I mainly researched Technologies of Point-of-Interest Recommendation on Location-based Social Network. My current research interests span Spatio-Temporal Recommendation, Spatio-Temporal Data Mining, Knowledge Graphs, Graph Neural Network, Federated Learning. If you’d like to know more about my work or explore opportunities for collaboration, please get in touch!

Research Interests

Spatio-Temporal AI : Spatio-Temporal Recommendation and Spatio-Temporal Data Mining

Graph Machine Learning : Graph Neural Network and Knowledge Graphs

Federated Learning : Federated Recommendation and Spatio-Temporal Federated Learning

Research DataSets

The datasets can be used for POI/next-POI recommendation, trajectory recommendation, friends recommendation (link prediction), activity recommendations, group recommendation and community discovery tasks:

Foursquare_FGCRec : Foursquare includes check-in data ranging from April 2012 to September 2013.

Gowalla_FGCRec : Gowalla contains check-in data ranging from February 2009 to October 2010.

Foursquare_FGRec : Foursquare includes the check-in data of users who live in California, ranging from December 2009 to June 2013.

Yelp_FGRec : Yelp contains a large number of geotagged businesses (also called POIs) and reviews within several cities.

Foursquare_CARec : We filter users who visited less than 10 POIs in Foursquare dataset and POIs visited by less than 10 users.

Yelp_CARec : We filter users who visited less than 32 POIs in Foursquare dataset and POIs visited by less than 31 users. https://www.yelp.com/dataset.

Foursquare_MUC : Foursquare contains check-in data ranging from January 2011 to July 2011.

Gowalla_MUC : Gowalla includes check-in data between Feb. 2009 and Oct 2010.
