AI Chatbot Explained: From the World’s First to Real-World Chatbot Applications

AI chatbots have taken center stage, completely transforming how businesses engage with their customers in today’s world of digital age. Not just as customer support agents, bots can take up any role they are given, from sales and marketing agents to virtual medical assistants. These digital assistants are quick and smart to respond to multiple customer queries simultaneously at any time with utmost personalization. What’s great, they fit perfectly across diverse industries.

Welcome to the forefront of the AI chatbot revolution!

What is an AI Chatbot?  

Technically, AI chatbots are either web interfaces or software applications trained on huge data for a specific purpose. They can imitate humans to communicate and respond like them either via text or in voice. All because of natural language processing (NLP) that empowers chatbots to learn and understand our language.

AI Chatbots Before ChatGPT and Bard

AI chatbots are not new, they have a long and interesting history and have existed since the 1960s. ELIZA was the world’s first chatbot. It was surprisingly not designed for ordinary conversation with users, rather to act as a virtual psychotherapist. ELIZA marked an early foray into natural language processing and laid the foundation for the development of more advanced AI chatbots in the years that followed.

• ALICE (1995): Created by Dr. Richard Wallace, ALICE (Artificial Linguistic Internet Computer Entity) was an early attempt at natural language processing and chatbot technology.
• Jabberwacky (1997): A chatbot created by Rollo Carpenter, Jabberwacky used machine learning techniques to engage in open-ended conversations.
• SmarterChild (2001): A popular chatbot on instant messaging platforms, SmarterChild offered information, and weather updates, and even engaged in casual conversation.
• A.L.I.C.E. (AIML Interpreter and Chatbot Engine) (2001): An open-source platform for creating chatbots, based on the AIML (Artificial Intelligence Markup Language) standard.
• Cleverbot (2008): Built on Jabberwacky's technology, Cleverbot is an AI chatbot that attempts to engage users in conversation and learn from interactions.
• Watson (2010): IBM's Watson, while initially known for its success in the quiz show "Jeopardy!", was a powerful AI system capable of natural language processing and providing detailed answers to user queries.
• Siri (2011): Apple's virtual assistant, Siri, brought AI-driven voice recognition and natural language understanding to a mass audience, allowing users to interact with their devices using voice commands.
• Amazon Alexa (2014): Amazon's voice-controlled virtual assistant, Alexa, powers the Echo line of devices and can perform various tasks and answer questions through voice commands.

• Google Assistant (2016): Google's virtual assistant, powered by natural language processing and machine learning, offers voice-based interaction, and performs various tasks for users.

How Do AI Chatbots Work?

There are three models on which AI chatbots work. These are pattern-matching methods, algorithms, and Artificial Neural Networks. Here's an explanation of how each classification method operates:

1. Pattern Matching Chatbots

Pattern matching chatbots are rule-based systems that rely on predefined patterns and rules to understand and respond to user inputs. These patterns and rules are created by human developers. When a user interacts with a pattern-matching chatbot, the system scans the user's input for specific keywords or phrases. If it identifies a match, the chatbot selects a predetermined response associated with that pattern or rule. 

For example, if a user types "What's the weather like today?" to a weather information chatbot, the chatbot might have a rule that recognizes the keyword "weather" and responds with the current weather forecast for the user's location.

Advantages: These chatbots are relatively simple to create and maintain. They work well for tasks with clear and limited interactions.

Limitations: Pattern-matching chatbots struggle with complex conversations and understanding context beyond predefined rules. They lack adaptability and can't learn from user interactions.

2. Algorithmic Chatbots

These chatbots use algorithms and decision trees to process user inputs and generate responses. They rely on logic and structured decision-making. When a user interacts with an algorithmic chatbot, the system analyzes the input using a series of programmed algorithms. These algorithms evaluate the input, follow decision paths, and select an appropriate response based on the logic defined in the algorithms.

For example, an algorithmic chatbot for troubleshooting electronic devices might ask the user a series of yes/no questions to diagnose the problem and provide a solution based on the answers.

Advantages: Algorithmic chatbots can handle more complex interactions than pattern-matching chatbots. They are suitable for decision-making tasks.

Limitations: These chatbots are limited by predefined algorithms and may struggle with understanding nuances in language and context.

3. Artificial Neural Network (ANN) Chatbots

ANN chatbots leverage deep learning techniques and artificial neural networks to understand and respond to user inputs. They are capable of learning from large datasets. ANNs process user inputs by passing them through layers of artificial neurons, which learn to recognize patterns and relationships in the data. Over time, the network adjusts its internal parameters to improve its ability to generate relevant responses.

For example, a customer service chatbot built using ANNs can understand a wide range of customer inquiries, learn from interactions, and provide more context-aware responses as it accumulates more data.

Advantages: ANN chatbots excel at natural language understanding, and context handling, and can improve their performance over time through continuous learning.

Limitations: They are more complex to develop and require large datasets for effective training. Additionally, ANNs may sometimes produce unexpected or incorrect responses if they encounter unfamiliar inputs.

What AI Chatbots Can Do for You?

These smart virtual creatures are capable of doing almost everything that can be trained for. But for a glimpse, we have listed five common and growing use cases of AI chatbots and how they're reshaping the landscape of customer engagement and business operations.

1. Customer Service: Elevating Support to New Heights

The simplest adoption of AI chatbots is in customer service. Customer service is the lifeblood and a critical aspect of business operations, but challenges such as availability, scalability, and consistency are also there. AI chatbots are redefining the way companies interact with their customers by overcoming all the challenges and offering instant and efficient responses to customer inquiries and issues

How does it work?
