Query variations and their effect on comparing information retrieval systems
International Conference on Information and Knowledge Management, 2016 We explore the implications of using query variations for evaluating information retrieval systems and how these variations should be exploited to compare system effectiveness.

Evaluating Generative Ad Hoc Information Retrieval [PDF]
Annual International ACM SIGIR Conference on Research and Development in Information Retrieval, 2023 Recent advances in large language models have enabled the development of viable generative retrieval systems. Instead of a traditional document ranking, generative retrieval systems often directly return a grounded generated text as a response to a query.

COIL: Revisit Exact Lexical Match in Information Retrieval with Contextualized Inverted List [PDF]
North American Chapter of the Association for Computational Linguistics, 2021 Classical information retrieval systems such as BM25 rely on exact lexical match and can carry out search efficiently with inverted list index. Recent neural IR models shifts towards soft matching all query document terms, but they lose the computation ...

Neural Approaches to Conversational Information Retrieval [PDF]
The Information Retrieval Series, 2022 A conversational information retrieval (CIR) system is an information retrieval (IR) system with a conversational interface which allows users to interact with the system to seek information via multi-turn conversations of natural language, in spoken or ...

On the Information Leakage in Private Information Retrieval Systems [PDF]
IEEE Transactions on Information Forensics and Security, 2019 We consider information leakage to the user in private information retrieval (PIR) systems. Information leakage can be measured in terms of individual message leakage or total leakage.

Information Retrieval and Criticality in Parity-Time-Symmetric Systems. [PDF]
Physical Review Letters, 2017 By investigating information flow between a general parity-time (PT-)symmetric non-Hermitian system and an environment, we find that the complete information retrieval from the environment can be achieved in the PT-unbroken phase, whereas no information ...
