Recent advances in neural information retrieval
About the speaker: Dr Guido Zuccon is an Associate Professor in Information Retrieval at The University of Queensland (Australia), and an ARC DECRA recipient. Guido also holds honorary positions at the UQ Faculty of Medicine, in Queensland Health as Principal Scientist (Adjunct) and at the University of Strathclyde (UK) as Honorary Reader. Guido’s research in Information Retrieval includes models and methods for search and evaluation, and domain-specific search.
Abstract: Search engine rankers powered by pre-trained language models like BERT have shown unprecedented gains in retrieval and ranking tasks, and have quickly become the focus of much of the research in Information Retrieval. Despite the powerful relevance modelling abilities of these methods, there are yet a number of challenges to be solved for these methods to be usable in practice across a wide range of scenarios and search providers; these include, among others: robustness of these rankers to out of distribution data, trade-off between effectiveness, efficiency and hardware, data and training efficiency, effective hybrid sparse-dense methods, integration of feedback methods. In this talk I will give a broad overview of the research produced to address these challenges by my research team at The University of Queensland, and I will then deep-dive into some of our methods.
