Introduction to the person in charge of Meituan B&B’s AI intelligent customer service，Since the launch of B&B conversation robot (AI intelligent customer service)，The accuracy of identifying user problems reaches more than 90%，Can maintain the intelligent speaking ability of large models，It can also improve the accuracy of question and answer。What is unimaginable is，The birth of this product，It is the result of the cooperation between the technical team of Meituan B&B and a young entrepreneurial team from Beijing。

Team leader Chi Xiaoyu holds double bachelor’s degrees in mathematics and economics from the School of Mathematical Sciences of Peking University and the China Economic Research Center (now the 188bet Online Sports Betting and Casino National School of Development of Peking University)，Graduated with a PhD from the Institute of Software, Chinese Academy of Sciences in 2009，Majoring in artificial intelligence and computer graphics。Before cooperating with Meituan B&B，Chi Xiaoyu is already a "leader" in the field of artificial intelligence theory;Top Experts”，In the key projects of the National Ministry of Science and Technology“Information Photonic Technology”Served as“Realistic near-eye three-dimensional display technology and device”Project subject leader。

2021，Chi Xiaoyu became attached to Meituan B&B，Become a&ldquo who has moved from the theoretical world to the applied world;Vanguard”。

Chi Xiaoyu said，Starting in 2021，The team actively participated in Meituan B&B’s“Open platform”In plan，Use your own technical accumulation in graphics and images to do some technical exploration and attempts。For example，At that time, the entire Internet industry’s information transmission method had switched from traditional graphics to video，And even these top short video platforms，In terms of generating content, we also rely more on a large number of creator ecosystems to provide content。Since the number of excellent creators is always limited，Therefore, generating high-quality content is actually relatively expensive and scarce。With the joint promotion of the platform’s technical team，The team tries to use some of the latest generative AI techniques，Such as video face-changing technology、Automated motion capture migration technology、Environmental lighting automatically obtains realism technology, etc.，Use technology to generate high-quality content in large quantities，To help the platforms we serve quickly generate high-quality video content。

The most important time node in this process is the end of 2022。At that time，Discuss with the relevant person in charge of Meituan B&B，The two key judgments reached helped Chi Xiaoyu make his decision: Firstly，The homestay industry will end the adjustment and dormancy period of the previous three years，Ushering in a new round of explosive growth，This will also generate a large number of service demands based on related businesses；The second is the development 188bet sports betting app download in the field of LLM (Large Language Model)。Although the overall effect of LLM in the past few years has not been amazingly improved compared to before，But in terms of model generalization ability and corpus processing ability，It has been gradually improved and is expected to bring huge changes and help to the field of intelligent customer service in terms of corpus cleaning and answer richness。

Therefore，Starting from the end of 2022，With the support of Meituan B&B，Chi Xiaoyu’s team and the platform jointly study how to use the latest technology and appropriate market timing，Serve all merchants and users on the platform well。In the B&B scene，Robots can help significantly reduce the workload of landlords，Especially in special service scenarios such as nights and holidays。At the same time，Integrate with landlord、User’s communication scenario，The robot can also fully automatically and intelligently extract historical conversations between landlords and tenants，And perform smart additions and services。

“In simple terms，As long as the landlord has answered the user's question once in history，Our intelligent system and language model will automatically record this service content，I will answer in richer and even playful language later。For example, you can answer based on the landlord’s history，Provide tenants with detailed surrounding dining information。”According to introduction，Parking policy for some remote and unpopular scenic spots、Parking fee，B&B conversation robot can also handle it accurately。And，For some frequently occurring service issues in the future，They will establish a set of intelligent model automatic training mechanisms to guide landlords to respond，Significantly improve the service quality and service capabilities of small and medium-sized landlords who lack energy and ability。

As a response system serving specific areas，Compared to the very popular OpenAI on the market or Microsoft’s Office365、Bing and other application forms are these“Public data covers large language models in all fields”，The accurate name of Meituan B&B’s AI intelligent customer service should be “Private data domain short question and answer language 188bet online sports betting large model service”。Chi Xiaoyu said，Problems caused by the excessive diversity of data across the entire network and the LLM pre-training (a machine learning method) mechanism，Use LLM to answer vertical questions，Hallucination (referring to the large model appearing to give incorrect answers when answering questions、The phenomenon of nonsense) rate is impossible to solve，This is caused by its technical principle。The technical path of Meituan B&B’s AI intelligent customer service is one that can maintain the intelligent speaking capabilities of the existing large model，A solution that can also ensure the accuracy and accuracy of question and answer。

Technology supports and drives the transformation of retail，Retail provides continuous resource investment and rich scenario support for technology。Talking about the relationship between platforms and small and beautiful technology companies，Chi Xiaoyu said，As a very large platform，The platform does need more energy and resources to invest in operational efficiency、Among deeper core business issues such as traffic business and business mechanism。The technology team can focus more on the application of new technologies，Go all out to overcome technical problems，And carry out practical application。“We hope that the platform will continue to maintain an open and sharing attitude，Building multi-party participation、Build a win-win industrial ecology，In the future, more technical partners will participate to improve the overall artificial intelligence application level of the industry，Create greater social value。”
