A Literature Survey of Recent Advances in Chatbots
It provides a comprehensive overview for researchers and practitioners, but is incremental as it synthesizes existing work without introducing new methods or data.
This survey reviews recent advances in chatbots, highlighting their use of AI and NLP, and identifies key challenges and limitations while providing recommendations for future research.
Chatbots are intelligent conversational computer systems designed to mimic human conversation to enable automated online guidance and support. The increased benefits of chatbots led to their wide adoption by many industries in order to provide virtual assistance to customers. Chatbots utilise methods and algorithms from two Artificial Intelligence domains: Natural Language Processing and Machine Learning. However, there are many challenges and limitations in their application. In this survey we review recent advances on chatbots, where Artificial Intelligence and Natural Language processing are used. We highlight the main challenges and limitations of current work and make recommendations for future research investigation.
