Abstract
In this digital world integrating smart city concepts, a smart city is a
technically advanced metropolitan region that collects data using various electronic
technologies, voice recognition methods, and sensor devices. It would not be wrong to
say that this smart city is based on the Internet of things (IoT) and artificial intelligence
(AI). The IoT and AI are closely related. IoT systems generate big data, and data is at
the heart of AI and machine learning. Simultaneously, as the number of linked devices
and sensors expands, the importance of smart technologies is also growing faster in this
domain. These technologies enable contextual understanding and allow smart devices
to solve our problems. Today, the applications of computational intelligence in IoT
products and smart devices used in smart cities vary. AI can be leveraged to drive
efficiency and improve human living quality for the smart cities of tomorrow. NLP
gives the powers to AI tools that recognize and respond in natural Language. This
chapter focused on a definite area of AI called Natural Language Processing, which
helps and enhances human living in smart cities. There are many use cases where this
AI technology makes sense for smart cities. Computerized healthcare services assist
policymakers in implementing smart cities in becoming brighter, using opinion mining
and permission to remodel a house. These use cases are achieved and discuss various
applications, scopes, techniques, advantages, disadvantages, and future scope of NLP
of AI in Smart Cities.
