Conversational AI - Chatbot Architectures and Evaluation

Analyzing architectures and evaluation methods for conversational AI systems, including chatbots, virtual assistants, and dialogue systems

Abstract

Conversational AI has emerged as a powerful technology, enabling natural language interactions between humans and machines. Chatbots, virtual assistants, and dialogue systems are key applications of conversational AI, with diverse architectures and evaluation methods. This paper presents a comprehensive analysis of these architectures, including rule-based, retrieval-based, and generative models, highlighting their strengths and weaknesses. Evaluation methods, such as human judgment, user studies, and automated metrics, are discussed in detail, emphasizing the importance of evaluating both functionality and user experience. The paper also explores current challenges and future directions in conversational AI research, aiming to guide researchers and practitioners in developing more effective and user-friendly systems.
