PC Chairs' Preface

摘要

It is our great pleasure to present the 25th Pacific-Asia Conference on Knowledge Discovery and Data Mining (PAKDD 2021). PAKDD is a premier international forum for exchanging original research results and practical developments in the space of KDD-related areas, including data science, machine learning, and emerging applications. We received 768 submissions from across the world. We performed an initial screening of all submissions, leading to the desk rejection of 89 submissions due to violations of double-blind and page limit guidelines. Six papers were also withdrawn by authors during the review period. For submissions entering the double-blind review process, each paper received at least three reviews from PC members. Further, an assigned SPC member also led a discussion of the paper and reviews with the PC members. The PC co-chairs then considered the recommendations and meta-reviews from SPC members in making the final decision. As a result, 157 papers were accepted, yielding an acceptance rate of 20.4%. The COVID-19 pandemic caused several challenges to the reviewing process, and we appreciate the diligence of all reviewers, PC members, and SPC members to ensure a quality PAKDD 2021 program.
