Introduction
Let us consider an illustration:
You are a customer and you arrive on a website to browse its services. A pop-up flashes on the screen that can assist you. It asks you a few scripted questions to deliver you a seamless experience. That’s what an AI Chatbot is.
AI chatbots can be described as Artificial Intelligence chatbots that are computer programs with the capabilities to interact with the end user through modern technologies, simulating a human interaction. AI chatbots are not only limited to websites, but have been buzzing around with their presence on social media, messaging apps, or even the games. AI chatbots being available 24/7 have helped businesses being quick to respond quickly to their customers, slashing the TAT (turnaround time), boosting efficiency, and improving the customer experience.
AI chatbots simulate conversations with users in a way that closely resembles human interaction. The traditional chatbots developed initially were a simple set of pre-programmed answers to the Frequently Asked Questions (FAQ’s). Being scripted, these bots were not able to solve or answer the complex problems or anything that lay outside their set boundaries.
With the evolution of technology, the Generative AI chatbots now offer enhanced functionality. These Gen AI chatbots are built on NLP techniques like tokenization and intent detection principles that were used in traditional bots, leveraged with LLM concepts in modern bots.
According to Gertner, “ By 2026, 50% of customer service and support organizations will have implemented Gen AI for assistance”. It will therefore improve customer experience and automate the tasks, thereby improving productivity.
What Makes a Chatbot ‘The Best’?
To meet the evolving needs of modern business, one must consider building an apt chatbot that makes it “The Best AI chatbots for business”. A chatbot is considered ideal if it is intuitive, can gracefully handle a variety of tasks, can understand human queries, and provides qualitative personalized interactions at a good speed.
An NLP chatbot or a Generative AI chatbot uses Natural Language Processing (NLP), a branch of Artificial Intelligence, to program software that can understand text, speech, images, audio, or video and reply to humans. The pre-processed data and machine learning algorithms help in training NLP. The use of NLP chatbot keywords plays an important role in making context-aware conversation rich and natural.
The Best AI chatbots are the ones that provide transparency, customization, and security measures. Based on the above factors, a chatbot could be either an Open Model or a Proprietary Model.
Open AI Model: The Open AI Model offers more transparency and so its vulnerabilities could be fixed easily since its code and data are available publicly.
Proprietary AI Model: Proprietary AI Model, on the other hand, is more secure since its data is available on an enterprise level and offers less transparency.
