The Evolving Chatbots
Making Future

Now we have already entered the third phase of Natural Language Processing. It's like the wait is over. After this hype of Artificial Intelligence, we see chatbots everywhere to make the work easy.
What are Chatbots?
A chatbot is artificial intelligence software designed to stimulate conversation with human users, especially over the Internet in the natural language. We already saw some there are Google Assistant, Alexa, Siri, etc. They are assigned to perform tasks like hotel booking, online orders, restaurant booking, and basic information about new ones, etc.

Broadly there are three types of chatbots:
- Self Learning or AI bots
- Rule-Based bots
- Voice-Based bots
1. Self Learning or AI bots
In this approach, we use some Machine-Learning based techniques. These AI bots can handle complex situations and are more effective than rule-based ones. If the company is getting multiple users at a time, these Retrieval Based AI bots can solve the problem simply because they trained before themselves on a set of questions and possible outcomes. For extreme conditions, Generative AI bots can generate the answers and not always reply with responses from a group of solutions.

2. Rule-Based bots
In this approach, a bot responds to questions dependent on specific guidelines on which it is prepared. These are pretty straightforward, and the rules can be detailed to highly unpredictable also, these are not as effective as AI bots. These bots can deal with specific inquiries yet neglect to oversee complex ones.

3. Voice bots — The Future
In the coming days, we will see this type of approach ultimately. We already saw some of these approaches used in Alexa or Google Assistant. The OpenAI company has already published the GPT-3 paper. GPT-3 (Generative Pre-trained Transformer 3) is the third phase of Natural Language Processing which can perform many things like making own blogs, story writing, etc. Many experts believe that we are very near to seeing the wonders in this artificial intelligence era.
