Prof. Raymond Chi-Wing Wong, His Past PhD Students and His Collaborator Obtained Prestigious Best Paper Award at ICDE 2024 for New Database Queries called Regret Queries

Prof. Raymond Chi-Wing Wong, two of his past PhD students (Weicheng Wang and Min Xie) and his collaborator (Prof. H. V. Jagadish) obtained the Best Paper Award at the 40th IEEE International Conference on Data Engineering (ICDE 2024) in Utrecht, Netherlands on May 13-16, 2024.

The title of this best paper is called "Reverse Regret Queries". This paper is one of the representative papers under the topic called "k-regret queries". It is a new kind of database queries. It has the advantages of two traditional popular queries in the database community, namely the top-k queries and the skyline queries. Specifically, this k-regret query has the advantage of the top-k queries (where the output size is controllable). Besides, it has the advantage of the skyline queries (where the user does not need to give his/her exact user preference function).

This new query is a query according to the perspective of a user. It could help a user to find a list of products the user is interested in. This best paper considers the perspective of a company (instead of a user). Now, in the existing market, there are a lot of existing products. The company wants to promote a new product. We want to find all users who are interested in the new product in this existing market where the user preference could be captured by the k-regret query.

ICDE is one of the first-tier conferences in the field of the database community. ICDE is a premier forum for the exchange and dissemination of data management research results among researchers, practitioners, developers, educators and users. The acceptance rate of ICDE 2024 is 22.75% (337 accepted paper out of 1481 submissions). The best paper is very competitive since there is only one best paper in this conference where the selection rate is 0.30% (one paper out of 337 accepted papers).

Congratulations to Professor Wong and his students for their outstanding achievement.
