Rehearse With User: Personalized Opinion Summarization via Role-Playing based on Large Language Models

ACL ARR 2025 February Submission4249 Authors

Abstract:

Personalized opinion summarization is crucial as it considers individual user interests while generating product summaries.
Recent studies show that although large language models demonstrate powerful text summarization and evaluation capabilities without the need for training data, they face difficulties in personalized tasks involving long texts.
To address this, Rehearsal, a personalized opinion summarization framework via LLMs-based role-playing, is proposed.
Having the model act as the user, the model can better understand the user's personalized needs.
Additionally, a role-playing supervisor and practice process are introduced to improve the role-playing ability of the LLMs, leading to a better expression of user needs.
Furthermore, through suggestions from virtual users, the summary generation is intervened, ensuring that the generated summary includes information of interest to the user, thus achieving personalized summary generation.
Experiment results demonstrate our method can effectively improve the level of personalization in large model-generated summaries.
