Congratulations to Prof Ong Yew-Soon, Chief Artificial Intelligence (AI) Scientist and Advisor, Dr Joey Zhou, Deputy Director and Principal Scientist and Mr Zhao Heng, Senior Research Engineer, on having their paper accepted at the 49th International ACM SIGIR Conference on Research and Development in Information Retrieval.

Their paper, titled “Agentic Spatio-Temporal Grounding via Collaborative Reasoning”, explores the Agentic Spatio-Temporal Grounder (ASTG) framework for the task of Spatio-Temporal Video Grounding (STVG) towards an open-world and zero-shot scenario, eliminating the requirements of per-frame spatial annotation in training and also per-frame reasoning in inference.

Held from 20 – 24 July 2026, in Melbourne, Australia, SIGIR 2026 will cover a wide range of topics, including search engines, recommendation systems, text mining, and related areas, making it a significant event for researchers and practitioners in the field of information retrieval.
