No. 43 ID: Use Case Name: Deep Learning Based User Intent Recognition
On-premise systems
StatusIn operation
ScopeRecognizing usersí intent to solve their problems in e-commerce fields
Objective(s)To recognize and understand usersí intent by AI and deep learning technologies and apply such technologies to build chat bot systems to further reduce labor cost and to be applied in various fields.
(up to
150 words)
Intelligent customer service chat bot is mainly used to categorize usersí questions, recognize usersí intents and answer usersí questions intelligently for different business jobs. Currently, this chat bot has been used to handle 90% of online customer service and has enabled to save over 100 million labor costs every year.
Complete Description has been committed to using technology to drive business growth and improve user experience in all customer service fields. Based on the improvement of customer consulting experience and the developing trend of artificial intelligence technology, as early as 2012, JD had decided to develop intelligent chat bots to fulfill the needs of continuous expansion of business, to save customer service costs and increase service capability. Intent recognition is a key and core technology to build such an intelligent customer service chat bot. By applying natural language processing technologies, deep learning technologies, traditional machine learning algorithms, intent recognition accuracy has reached to 95%. Based on accurate intents, and a series of solution finding algorithms, our chat bot can solve the userís problems to a great extent and give the user a high quality consulting experience. Finally, in order to provide diversified and personalized customer services, we are continuously improving the accuracy of intent recognition, personalized solution generation, sentiment recognition, and image recognition. So far, intelligent customer service has revolutionized the traditional customer service consulting business.
