The Glasgow Information Retrieval Group within the School of Computing Science at the University of Glasgow was founded 32 years ago in 1986 by Professor C. J. ‘Keith’ van Rijsbergen, often considered one of the founders of modern Information Retrieval (IR). From its outset, the Glasgow IR group has focused on improving the effectiveness of IR systems, inventing new logic & probabilistic retrieval models in the 90's and early 2000's, followed by the development of adaptive query expansion techniques, interactive multimedia models, the Divergence From Randomness framework, as well as leading research into quantum, expertise search and search result diversification models in the late 2000's. Since then, the Information Retrieval group embraced emerging machine learning and deep learning technologies for very large corpora and data streams, and have been at the forefront of research, development and application of those technologies for search and recommendation use-cases in a manner that ensures both effectiveness and efficiency.

The Glasgow IR Group has a strong research track record. Indeed, the ACM Digital Library shows that the group is ranked first by number of papers (429) at the SIGIR conference (the top CORE A* conference in the IR field). Meanwhile, a recent study by Microsoft Research of the 40 years of SIGIR showed the University of Glasgow as the 5th most cited university at the conference and the 1st in Europe. The group is also renowned for developing the popular open source IR platform, Terrier.org, which has been downloaded over 60,000 since its first release in 2004 and is cited by over 3500 research papers. Furthermore, the group has a long history of engagement with the public and industry sectors from small SMEs to multinational corporations.

The Informer magazine of BCS's Information Retrieval Specialist Group carried a recent profile on the Glasgow Information Retrieval Group.

Terrier IR platform

Terrier is a highly flexible, efficient, and effective open source search engine, readily deployable on large-scale collections of documents developed by the IR group. Terrier implements state-of-the-art indexing and retrieval functionalities, and provides an ideal platform for the rapid development and evaluation of large-scale retrieval applications. Indeed, Terrier is used internationally, with over 60,000 downloads since its first release in 2004. Terrier is is used widely by the research community, with over 3700 citations in research papers according to Google Scholar.

Popular resources

For those new to the Information Retrieval field, the group maintains a useful set of common resources for researchers and practitioners:

  • Information Retrieval Test Collections: On this page are a list of publically available IR test collections. Some are held locally and some are pointers to remote sites.
  • Collections of text and corpora: What's the difference between a test collection and a text collection? Well a test collection has to have associated queries and relevance judgements. The things in here are simply document collections.

Building Trustworthy Recommendation System

Group: Information Retrieval (IR)
Speaker: Xinghai Hu, Tiktok
Date: 02 December, 2024
Time: 15:00 - 16:00
Location: Sir Alwyn Williams Building, 422 Seminar Room

Title
Building Trustworthy Recommendation System

Abstract
Recommender systems have become integral to various facets of modern life, shaping how individuals engage with entertainment, commerce, news, and information. With these systems' increasing social and economic influence, ensuring their trustworthiness is more critical than ever. This talk will explore the evolving responsibility of recommender systems within a multi-agent paradigm, addressing their obligations not just to users, but to society at large. We will examine key drivers of trust—including safety, control, diversity, and transparency —and the technical challenges in building systems that are both effective and responsible. The session will conclude with a discussion on emerging AI opportunities to create more reliable recommendation systems.

Bio
