GVEC: A Generative Vietnamese Chatbot for Economy, Using Vietnamese Economy Information Database from VnEconomy Community

Currently, the problem of automatic question answering (Q/A) with applications in chatbot services has become essential, addressing various issues in daily life. There are many approaches to solving this problem, but each presents its own challenges. The generative AI approach has recently gained widespread attention due to its ability to provide smooth, human-like responses. However, it has the drawback of producing coherent-sounding but inaccurate or fabricated content, known as "hallucinations". In this study, we aim to find a solution for the question-answering task in the context of the Vietnamese economy. We propose the Generative Vietnamese Economy Chatbot (GVEC), based on the Vietnam Economy Information Database (VEID) retrieved from VnEconomy systems. Our proposition is to apply Retrieval-Augmented Generation (RAG) to various LLM systems and test them on our specially designed benchmark, called the Vietnamese Numeric Economy Information Question/Answer Datasets (VNEIQAD), generated by our Question/Answers Generating with Numerical Information (QAGwNI) algorithm. This will help better evaluate the solution in the economic context.
