The First Late Interaction Workshop (LIR) @ ECIR 2026
The 1st Late Interaction Workshop (LIR) @ ECIR 2026 is a half-day hybrid forum dedicated to advancing research on late-interaction retrieval methods, such as ColBERT and multi-vector approaches. It brings together researchers and practitioners to discuss theoretical insights, efficiency challenges, usability improvements, and novel applications like multi-modal and reasoning-based retrieval.

Policies worth checking twice
- Submissions are single-blind by default.
- We welcome pre-prints and arXiv submissions. Prior availability as a pre-print will not negatively impact your review.
- Page limits exclude references, acknowledgements, and limitations sections.
- All submissions will be reviewed for relevance to the workshop and the community at large.
- Authors will be individually contacted to decide whether their accepted submission will be archival or non-archival.
