🪩 DiSCo: LLM Knowledge Distillation for Efficient Sparse Retrieval in Conversational Search Simon Lupart, Mohammad Aliannejadi, Evangelos Kanoulas → Full paper: Enhance retrieval in conversational systems using a simple distillation method on LLMs. arxiv.org/abs/2410.14609

✨ Conversational Gold: Evaluating Personalized Conversational Search Systems using Gold Nuggets Zahra Abbasiantaeb*, Simon Lupart* (equal), Leif Azzopardi, Jeff Dalton, Mohammad Aliannejadi → Resource: Conversational nugget-based evaluation dataset iKAT arxiv.org/abs/2503.09902

💡 Reproducing NevIR: Negation in Neural Information Retrieval Coen van den Elsen, Francien Barkhof, Thijmen Nijdam, Simon Lupart, Mohammad Aliannejadi → Reproducibility paper — I supervised this work exploring how IR models handle negation. arxiv.org/abs/2502.13506

And this is just the beginning of Simon’s PhD journey. Amazing achievement with four contributions at #SIGIR2025, kudos!

LLMs are reshaping how we evaluate ranked lists, conversations, and even simulate users. At #LLM4Eval @ #SIGIR2025, we’re spotlighting 3 special themes: 🧠 Beyond query-doc 🗣️ Simulating users 🧪 Synthesizing evaluation data 👇 Curious? Read on & submit by April 23! #LLMs #IR

We will host multiple breakout discussions to pick your brains 🧠 on the future challenges and research on this topic. Let's shape the LLMEval research agenda. Interested? Already have thoughts and ideas? Then, submit your extended abstracts or just join us in the workshop.

Happy to share that our tutorial “Conversational Search: From Fundamentals to Frontiers in the LLM Era”, with Fengran Mo, Mohammad Aliannejadi and Jian-Yun Nie, got accepted at SIGIR 2025 #SIGIR2025! Look forward to engaging discussions on LLM-based and agentic conversational search.

📢 Deadline extended! Submit to #LLM4Eval @ #SIGIR2025 by April 30 (AoE) We welcome work on LLM-based evaluation, including: 🧠 beyond query-doc 🗣️ simulating users 🧪 synthetic eval data 🔗 llm4eval.github.io/SIGIR2025/cfp/ #CFP #IR #LLMs #SIGIR2025

Excited to share that our paper "Query Performance Prediction using Relevance Judgments Generated by Large Language Models" has been accepted by ACM Transactions on Information Systems (TOIS), with Negar Arabzadeh, Arian Askari, Mohammad Aliannejadi, Maarten de Rijke. dl.acm.org/doi/10.1145/37…

Israeli strikes have killed dozens of Iranian civilians so far: a photographer, skater, programmer, artist, nurse ... young and bright individuals with families, names, dreams, and hopes.

I defended my PhD thesis "Optimizing Agentic Workflows for Information Access" on 19 June 2025. I’m deeply grateful to my supervisors Maarten de Rijke and Mohammad Aliannejadi. Thanks to my committee members, Evangelos Kanoulas, Christof Monz, Zhaochun Ren, Andrew Yates, and Emine Yilmaz.

On July 8th, I successfully defended my PhD 🎓✨ My thesis, "Rethinking the Human-Centered Evaluation of Conversational Systems," explores aligning conversation evaluation with real human needs. Thanks to my supervisors Maarten de Rijke and Mohammad Aliannejadi for their support.
