Deep research has emerged as an important task that aims to address hard queries that need extensive open-web exploration. To tackle it, most prior work equips large language model (LLM)-based agents with opaque web search APIs, enabling agents to iteratively issue search queries, retrieve extern...

Shared tasks offer excellent opportunities for advancing scientific fields and standardizing evaluation methods through collaborative community efforts. With the recent paradigm shift in information retrieval from keyword-based to conversational search, shared tasks can serve as promising sources...

Conversational search agents, especially with the advent of large language models, have developed into useful tools to satisfy complex information needs of their users. Former research has shown that personalization (i.e., adaptation of agent responses to the preferences and traits of the user) c...
