Creating a chatbot can be a fun and educational project to help you acquire practical skills in NLP and programming. This article will cover the steps to create a simple chatbot using NLP techniques. Without NLP, chatbots may struggle to comprehend user input accurately and provide relevant responses. Integrating NLP ensures a smoother, more effective interaction, making the chatbot experience more user-friendly and efficient. To a human brain, all of this seems really simple as we have grown and developed in the presence of all of these speech modulations and rules. However, the process of training an AI chatbot is similar to a human trying to learn an entirely new language from scratch.

Three Pillars of an NLP Based Chatbot

NLP allows computers and algorithms to understand human interactions via various languages. NLP is a tool for computers to analyze, comprehend, and derive meaning from natural language in an intelligent and useful way. This goes way beyond the most recently developed chatbots and smart virtual assistants.

Inaccuracies in the end result due to homonyms, accented speech, colloquial, vernacular, and slang terms are nearly impossible for a computer to decipher. Contrary to the common notion that chatbots can only use for conversations with consumers, these little smart AI applications actually have many other uses within an organization. Here are some of the most prominent areas of a business that chatbots can transform. Users would get all the information without any hassle by just asking the chatbot in their natural language and chatbot interprets it perfectly with an accurate answer. This represents a new growing consumer base who are spending more time on the internet and are becoming adept at interacting with brands and businesses online frequently.

With the addition of more channels into the mix, the method of communication has also changed a little. Consumers today have learned to use voice search tools to complete a search task. Since the SEO that businesses base their marketing on depends on keywords, with voice-search, the keywords have also changed. Chatbots are now required to “interpret” user intention from the voice-search terms and respond accordingly with relevant answers. This reduction is also accompanied by an increase in accuracy, which is especially relevant for invoice processing and catalog management, as well as an increase in employee efficiency.

By the end of this guide, beginners will have a solid understanding of NLP and chatbots and will be equipped with the knowledge and skills needed to build their chatbots.
