Abstract

Question-Answering (QA) systems are important in Communities of Practice (e.g., Stack Overflow), by facilitating more effective access to and aggregation of collective knowledge. However, the contemporary QA systems offer standardized answers to similar questions without accounting for users’ diverse knowledge backgrounds, which fail to solve users’ problems. In response, we propose the K-PAG method, which generates personalized answers tailored to the users’ knowledge backgrounds using LLM. Grounded in scaffolding theory and cognitive load theory, the K-PAG identifies the most cognitive-efficient knowledge path that connects users’ existing knowledge concepts to new concepts. The path is then used as a guide to prompt LLMs to generate personalized answers. A cooperative training framework is proposed to reinforce both the path-planning model to generate knowledge paths that better align with the user’s knowledge background and the LLM’s ability to follow knowledge paths during answer generation. Experiment shows K-PAG outperforms benchmarks on generating personalized answers.

Personalized Answer Generation Based on Individual Knowledge Background Using Large Language Model

Question-Answering (QA) systems are important in Communities of Practice (e.g., Stack Overflow), by facilitating more effective access to and aggregation of collective knowledge. However, the contemporary QA systems offer standardized answers to similar questions without accounting for users’ diverse knowledge backgrounds, which fail to solve users’ problems. In response, we propose the K-PAG method, which generates personalized answers tailored to the users’ knowledge backgrounds using LLM. Grounded in scaffolding theory and cognitive load theory, the K-PAG identifies the most cognitive-efficient knowledge path that connects users’ existing knowledge concepts to new concepts. The path is then used as a guide to prompt LLMs to generate personalized answers. A cooperative training framework is proposed to reinforce both the path-planning model to generate knowledge paths that better align with the user’s knowledge background and the LLM’s ability to follow knowledge paths during answer generation. Experiment shows K-PAG outperforms benchmarks on generating personalized answers.
