Sci-fi has been an inspiration for some amazing modern-day innovations. 3D holograms (Start War), 3D printing (Star Trek), Video calling (Thunderbirds). In fact, your favorite sci-fi character J.A.R.V.I.S. is the inspiration behind one of the sought-after innovations today- chatbots. 

Developed by Tony Stark, J.A.R.V.I.S. was an intelligent bot that responds to the user’s thoughts. Connected to global information networks, it used holograms as an interface to communicate with Stark and give him access to anything he needs or wants.

Inspired by this Sci-fi AI character, Mark Zuckerberg created its own version of Jarvis- a personal virtual assistant to manage his home. 

Apple and Google created their own versions of Jarvis for their users in the form of Siri and Google Assistant (which would have functionality like Jarvis at a low dimension). Businesses are creating their own platforms to connect with customers, answer their queries, and a lot more that a human would do.

These conversational bots, called chatbots have a long history of evolution. They have evolved from a basic text-based chat window to an advanced, interactive conversational platform. The coming segment discusses how chatbots have evolved over time and what they are capable of doing today. 

A Brief History of Chatbots 

While many of us would agree that chatbot has become a buzzword only half a year back, but the concept has its existence from the time when people started developing ways to interact with computers. The first-ever chatbot was introduced even before the launch of personal computers. It was developed by MIT Artificial Intelligence Laboratory by Joseph Weizenbaum in 1966 and was named Eliza. 

Eliza examined the keywords received as input and then triggered the output according to a defined set of rules. This methodology of generating output is still used by a number of chatbots. 

The next chatbot was Parry, written by psychiatrist Kenneth Colby at the Stanford University in an attempt to simulate a person with paranoid schizophrenia. Then came the A.L.I.C.E, which was developed in 1995 by Richard Wallace. While A.L.I.C.E won the Loebner prize thrice, it failed to pass the Turing test. A Turing test examines whether or not a machine is able to think intelligently like humans. 

In the first decade of the 21st century, Smartchild robot was built ActiveBuddy. This new-era chatbot was not only a source of entertainment but provided stock information, sports score, movie quotes, and more. It was a part of AOL and Windows Live Messenger, which had a userbase of billions. 

After this, a line of virtual assistants was launched. While Siri by Apple was the first one to introduce conversational assistants, similar concepts gained popularity When Google launched the Google Assistant for Android, Microsoft brought Cortana into existence. 

Taking this a step ahead, smart speakers were introduced which made voice conversation possible between humans and the bot. Amazon Alexa, Google Home represents a different category of conversational UI.

Chatbots in the Recent Past 

Chatbots have got an edge in the recent past because of two prominent reasons: 

  1. Messaging Platforms
  2. Technology  

In 2015, Telegram opened its app for developers to build and deploy bots. Following this, Facebook opened its messaging platform, the Facebook Messenger for bot development and it garnered the attention of users as well as developers. Now, almost every popular platform including Whatsapp, Slack, We Chat, IMO offers the facility to build a chatbot. 

Over time, there is an advancement in the abilities of a chatbot and technology has been a real contributor to it. Artificial intelligence and its technologies have been helping developers in taking chatbots and their functionality to the next level. Today, chatbots are performing financial transactions, processing orders, resolving customer queries, and a lot more. We will be talking about it in detail in the upcoming segment. 

Chatbots: Then and Now 

The journey of chatbots from 1960 till date has been interesting. Chatbots have evolved in functionality, interface, and their significance to the business world cannot be ignored. Here is a glimpse of how progressive chatbots have been so far.  

Tasks and Roles Performed: Chatbots have been a great conversational agent for businesses. For a long time, they were an efficient replacement of a customer service provider who is there for the customers 24/7. However, with chatbots being able to take new roles and responsibilities, they have become an alternative to mobile apps. 

From simple conversations to complex transactions, chatbots are made to do almost everything. They are now used by businesses, irrespective of the industry and are used for placing orders, checking the status of the order, book flight tickets, make financial transactions, handle complex queries of the clients/customers, improve marketing campaigns, and a lot more. In short, chatbots are new apps for businesses. 

Enhancement in UI Elements: As the chatbots evolve with better abilities, there is a shift in their UI elements as well. They have a Conversational User Interface (CUI) which brings a change to the way human-computer interaction occurs.

CUI uses Natural Language Processing (NLP) that enables computers to understand, analyze, and create meaning from human language. NLP also takes up and process unstructured inputs (such as questions with spelling mistakes), helps in sentiment analysis, and more. 

Depending upon the functionalities performed, a number of graphic elements are added to the chatbot. Along with text messages, there are carousels, buttons, quick reply, web view, group chat, option to share audio, video, document file, image, GIF, and more.  

Technology Stack for Development: Chatbots are made to do a lot of things. Depending upon what a chatbot has to do, different technologies are adopted by the development community to build a chatbot. There are tools (like ChatFuel, API.ai, Botsify) that help to build a chatbot with less technical expertise. Then, there are technologies like Machine Learning, Natural Language Processing, RPA that can take chatbot abilities to the next level. Such abilities can be integrated by opting for custom chatbot development

Modes of Communication: Chatbots have evolved over time to enable text and voice communication possible. Chatbots working in collaboration with virtual assistants or smart speakers allow users to give input and receive output in a voice format. Here is a perfect example of it- Mark Zukerberg's Jarvis.

Significance of Chatbots for Businesses

As chatbots evolve with better functionality and features, businesses, irrespective of the industry, have been using chatbots to improve efficiency in operations, customer service, cut down errors, and more. While chatbots have various benefits to offer, it is important for businesses to examine the right use case of this technology and then implement it.
