Title: "A SURVEY ON CONSTRUCTION AND ENHANCEMENT METHODS IN SERVICE CHATBOTS 
DESIGN"

by

Mr. Zhenhui PENG


Abstract:

Chatbots are being widely applied in many service industries to help schedule 
meetings, online shopping, restaurant reservations, and customer care and so 
on. The key to the success of the service chatbots design is to provide 
satisfying responses to the given user’s requests. This survey aims to provide 
a comprehensive review of chatbots construction and enhancement methods. We 
first introduce major techniques for the three core design philosophies, which 
are rule-based, retrieval-based and generation-based methods, followed by a 
brief summary of the evaluation metrics. Then we present methods which service 
chatbot’s capabilities with either an ensemble of multiple chatbots, 
collaborating with human workers or learning from users. Finally, in future 
directions we discuss the promising response generation models for chatbots 
using the recent progress in the Transformer and contextual embeddings, as well 
as potential ways to construct a chatbot with personality to achieve a better 
user experience.
