Chatbots: Definition, Functions & Use


What Is a Chat Bot

Software that does exactly what humans do… This idea isn’t new, and, maybe there are fewer and fewer people to be impressed by chatbots, however, you can’t even imagine how powerful the chatbots of today can be. 

Extensive use of various messengers where users hang out much of their time boosts the chatbots popularity. Digital friends and assistants, chatbots now perform a plethora of functions from educational and therapeutic to travel or meeting planning. 

But what is actually a chat bot? 

Simple (or not as simple as you can imagine) software that stimulates interaction by imitating human written or spoken speech.

The meteoric chatbot rise resulted from the desire of the brands to improve communication with end-users. Actually, it has changed the communication drastically. Visiting the biggest e-commerce platforms, a user may get an immediate response to the question at any time without waiting morning to come, for example. 

Moreover, the enormous number of tasks can be addressed through the interface consisting of numerous elements. The list of such tasks starts from the routing ones (booking, takeout) to job-related tasks. By replacing the interface where a user should take several actions to reach the goal by a chatbot, you’ll make users’ life easier, thus, enhance the User Experience of your website or app and decrease its bounce rate that seems to be a sound idea.

In addition, chatbots may replace the live chats so that cutting the costs or focus resources on getting more significant problems solved could be possible. Of course, the situation when a chatbot is unable to meet the customer demands or resolve challenging issues is rather possible, thus, as a chatbot owner, you should definitely leave a user the possibility to send a request to site’s support. 

Gartner forecasts that by 2020, over 85% of customer interactions will be handled without a human.

That is why a business owner/ CTO/ manager should consider the possibility of chatbot introduction to improve the customer service and make the information accessible 24/7. All the more value of global chatbot market is going to increase significantly in the future:

How Do Chatbots Work

After defining chatbots, understanding the major principles of their work would be a great idea. As chatbots could be conditionally divided into two big categories: simple chatbot (question-answer chatbot or conversational agent) that recognize the most frequently asked questions basing on pre-prepared commands, and chatbots that use all the potential machine learning gives to imitate a human interlocutor as precisely as possible. 

The first category includes different chatbots for business (the ones you usually can see on websites that offers all kinds of products). As a rule, communicating with such chatbots, a user gets the list of standard questions, to which a chatbot may reply using the recognition of the prescribed keywords.

The second category can be represented by the well-known voice assistants Siri (Apple), Alexa (Amazon), Google Assistant, etc. that may actually give rise to a whole new epoch of the internet search, making it more human-like.

Compare two search requests: 

“Gas station near me” (that a person will probably enter into the search engine);

“Siri, show me the nearest gas station, please” (that a person will probably tell a voice assistant with an intention to find the gas station).

You shouldn’t be a SEO expert to see the difference between these two requests. So, smart chatbots are able to recognize a human intent disregarding the form of the user’s input. 

This comparative characteristic is intended to make the difference between simple and smart chatbots clear: 

Simple chatbotsSmart chatbots
Are based on…pre-written keywordsAI
Learn from conversation
Use prescribed conversations steps (are strictly limited)
Recognize user’s free form input
Process user’s input despite the mistakes of all kind
Can be easily implemented

Despite the numerous differences, both simple and smart chatbots (except for the ones that offer only prescribed lines to a user) have the same work structure:

Simple chatbot receives user's input, recognizes the intent, and pick up the most appropriate response in the database

Main Chatbot Features

As you can tell, chatbots of today are all different depending on the functions their creators had an objective to include. However, all (good) chatbots without exceptions have several common traits.

So, what should good chatbots do?

  • Simplify our lives. The main objective of both simple and smart chatbots is to save the user time by shortcutting to a goal. In case if user intent is to find out whether the e-shop delivers in certain countries, a chatbot will give this info right away so that a site visitor should not waste time trying to find the proper paragraph on the website containing this info.
  • Give the impression of human touch. No matter are you talking to a simple or smart chatbot, the main objective of both is to give a user an impression he/she is communication with a human being, so chatbots should be more personalized than any of the apps you’ve dealt with before. 
  • Provide extended support to their users. As users turn to chatbots in order to make their life easier, the existence of proper documentation and the possibility to get timely assistance through a chatbot itself (e.x. “Help”, “How it works” sections) are of high importance. Moreover, giving hints about additional functionality to a user through the chatbot itself is a great idea as well.
  • Interact in a short and simple manner. Users of today have less and less time to be wasted on the investigation that is why the quicker chatbot meets customer needs, the more satisfied a user becomes. 

What Can a Chatbot Do?

1. Hold a conversation

This is probably the main reason for chatbots creation. But why are people so curious about communicating with AI chatbot instead of talking to their own kind?

  • High response rate. Chatbots mission is to satisfy human curiosity right here right now, thus, it’s always easier to turn to a chatbot in order to get an immediate response. 
  • Entertainment. Why not chat with a chatbot when you have to kill another hour? Especially if it is able to give you a few funny tips imitating being a human. 
  • Novelty. Chatter bots are a relatively recent invention so that a man is still curious about a chat bot meaning and working algorithms. Even more curious is he to gossip about the boss and see a chatbot reaction to the funniest meme he’s ever laughed at.

2. Increase end-user engagement by improving customer service

Chatbots can provide the answers to the frequently asked questions immediately so that you shouldn’t wait for the support agent to come or stay up all night thinking of whether this e-shop provides delivery in other countries or not. Of course, in most cases, a user may get his information on the FAQ page, however, justified by highly competitive e-commerce environment, a user prefers to go on another site instead of wasting time to find answers on his/her questions. In this way, chatbots may help increase the conversion and boost user engagement. 

3. Reduce a set of routine actions a user performs to only one command

From 4 actions to one request:

Bran wants to buy a car. A used one to save money, but he also wants to check the information about used cars warranties, as his friend once told him that used car with warranties is better than without it. He types his request into a search engine and finds one of the numerous sites:
