Rehearse With User: Personalized Opinion Summarization via Role-Playing based on Large Language Models
This addresses the problem of generating tailored product summaries for individual users, though it appears incremental as it builds on existing LLM capabilities for personalization tasks.
The paper tackles the challenge of personalized opinion summarization for long texts using large language models (LLMs), proposing a role-playing framework called Rehearsal that improves personalization levels in generated summaries.
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, \textbf{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 that our method can effectively improve the level of personalization in large model-generated summaries.
