We compare our initial fine-tuning method to in-context learning approach for LLM-based user simulation. We also find patterns in the types of generated utterances (shown below) and quantify their prevalence. This is an extension of our WSDM'22 paper:.

Crowdsourcing-based results show the preferance of rewritten answers, compared to the original one. However, they indicate high subjectivity in preference of rewerite type and entities explained, thus calling for further personalization in conv search.

We thus investigate the presence of salient entities in conv search answers and propose two rewriting strategies:.1) explicit in-line explanations, making the answer self-contained;.2) asking a follow-up question, offering more info on salient entities in the answer.

We argue that conv search limits the user to explore entities that they might be unfamiliar with, but are crucial for understanding the system's answer. This is easier in Web search, as users can easily follow hyperlinks or consult other SERP elements.

I am greatful for the oppurtunity to work with and learn from so many great researchers. Some of them became collaborators, some of them friends 😊. Most importantly, I want to thank my (growing) family (@yoga4academics) for keeping me grounded and loved throughout the journey 🧡.
