A Question-Answering System for Vietnamese Public Administrative Services
Anh Pham Duy, Huong Le Thanh · 2023
In the realm of legal question-answering (QA) systems, information retrieval (IR) plays a pivotal role. Despite thorough research in numerous languages, the Vietnamese research community has shown limited interest in legal information retrieval, particularly in the context of public administrative services. In this paper, we propose the development of a QA system tailored to the Vietnamese language, specifically focusing on the domain of public administrative services. Our system provides legal-based responses, and it is built upon a combination of retrieval and re-ranking techniques. We employ both lexical-based and semantic-based retrieval models and integrate them to create the final model. Our research shows that the system outperforms existing models in retrieving public administrative information and answering questions related to Vietnamese legal documents.
