CHIIR 2025 Tutorial: Applying Large Language Models to Interactive Information Retrieval

Overview

This half-day interactive tutorial introduces researchers to practical applications of Large Language Models (LLMs) for Interactive Information Retrieval (IIR). Through hands-on exercises and real-world research scenarios, participants will learn:

  • How to integrate LLMs via APIs
  • Ways to evaluate their outputs in IIR settings

The tutorial will help attendees choose suitable models for different research needs and provide them with tools to enhance their work. No prior experience with LLMs is required, though familiarity with basic programming concepts is recommended.

Learning Objectives

By the end of the tutorial, participants will:

✅ Cover basic theoretical foundations of LLMs in IIR
✅ Gain hands-on experience in running LLMs via APIs
✅ Learn to use LLMs for real-world research tasks such as query generation, document relevance assessment, and user interaction modeling
✅ Develop a critical perspective on LLM capabilities and limitations
✅ Stay updated on recent advances in LLMs for search and retrieval

Target Audience

This tutorial is designed for:

  • Researchers and students (PhD students, postdocs, academics)
  • Industry professionals working with search technologies
  • Human-centered researchers in fields such as human-computer interaction (HCI), conversational AI, and information access
