Rule-Based Chatbots vs AI Chatbots: Key Differences

Botpress leverages natural language processing (NLP) to understand and interpret human language, providing a more human-like interaction. It comes with an intuitive visual flow builder that enables users to design conversation flows, manage content, and implement user interfaces. ChatGPT uses advanced natural language processing techniques to understand and respond to user input. This means that users can communicate with the chatbot in a more natural way without having to use specific commands or keywords. Nobody likes to be alone always, but sometimes loneliness could be a better medicine to hunch the thirst for a peaceful environment. Even during such lonely quarantines, we may ignore humans but not humanoids.

Chatbot, short for chatterbot, is an artificial intelligence (AI)

feature that can be embedded and used through any major messaging applications – Wikipedia. In the script above, we first set the flag continue_dialogue to true. After that, we print a welcome message to the user asking for any input.

Creating and operating the chatbot

First and foremost, the Chatbot should understand your targeted audience’s preferences and general mood. It should provide simple and clear answers to their queries seamlessly without any delays. A well-trained AI bot can resolve multiple queries more accurately than its rule-based chatbot counterpart. From a pure business perspective, AI chatbots have more value as they can respond to hundreds of queries simultaneously. Companies deploy AI chatbots when they intend to stimulate human-like behavior.

But an advanced AI bot that offers more interaction with your customers comes with premium packages. And unsurprisingly, a paid AI chatbot offers better accuracy and efficiency than a free chatbot. One major downside of AI bots is the high cost, as they require extra resources to mimic a human-like conversation. But simultaneously, they can handle multiple, complex tasks for the marketer.

How does a rule-based chatbot work?

This article will discuss everything you need about rule-based vs. AI chatbots. Keep reading and learn what type of Chatbot is right for your organization. It’s important to remember that, at this stage, your chatbot’s training is still relatively limited, so its responses may be somewhat lacklustre. The command ‘logic_adapters’ provides the list of resources that will be used to train the chatbot.

First, we will make an HTML file called index.html inside the template folder. Python includes support for regular expression through the re package. Today, Python has become one of the most in-demand programming languages among the more than 700 languages in the market.

Conversational AI can guide visitors through the sales funnel, improving the customer base. The relevant questions generated by artificial intelligence actively connect potential customers with a live agent when necessary. A good customer base increases brand awareness, improving brand credibility. The conversation process becomes more complicated (and time-consuming) when a rule-based chatbot transfers the connection to a live agent without resolving the issue.

What is rule-based chatbot vs AI based chatbot?

AI chatbots, in contrast, are used for more complicated cases to fully resolve customers' issues. Also, rule-based bots are limited by typos or wrong keywords that people might use. This is why rule-based chatbots require more data for automated customer service training.

Unquestionably, one of the best uses of natural language processing is chatbots (NLP). Known as NLP, this technology focuses on understanding how humans communicate with each other and how we can get a computer to understand and replicate that behavior. It is expected that in a few years chatbots will power 85% of all customer service interactions. AI-based chatbots can answer complex questions with machine learning technology. Chatbots with artificial intelligence understand the user intent without delay. Artificial intelligence and machine learning technologies in chatbots overcome the sales obstacles in the conversation.

ChatGPT represents the latest evolution of AI technology by utilizing deep learning techniques and large language models to understand and generate human-like language. Its unique capabilities include the ability to understand the context and generate coherent responses, as well as the ability to learn from vast amounts of data. ChatterBot uses entire sentences when responding due to being trained with minimal data amounts. Your chatbot shouldn’t sound less human and conversational; therefore, it is best to delete this data.

We use the RegEx Search function to search the user input for keywords stored in the value field of the keywords_dict dictionary. If you recall, the values in the keywords_dict dictionary were formatted with special sequences of meta-characters. RegEx’s search function uses those sequences to compare the patterns of characters in the keywords with patterns of characters in the input string.

Let us try to build a rather complex flask-chatbot using the chatterbot-corpus to generate a response in a flask application. Implement fallback responses for scenarios where the chatbot cannot understand or answer user queries. At this step, it’s time to assemble everything and train your chatbot using exported WhatsApp conversations. Enjoy playing with it at this stage, even if the conversations seem nonsensical.

We will begin building a Python chatbot by importing all the required packages and modules necessary for the project. We will also initialize different variables that we want to use in it. Moreover, we will also be dealing with text data, so we have to perform data preprocessing on the dataset before designing an ML model. The chatbot did not recognize the simple “easy yoga” request in our first example. So, as you can see, we will have to add more data to our JSON file for the convo to run smoothly. We constantly update and structure new data so the chatbot can return a fluid, more human-like response.

The responses are described in another dictionary with the intent being the dictionary, multiple such sequences are separated by the OR | operator. This operator tells the search function to look for any of the mentioned keywords in the input string. Let us consider the following snippet of code to understand the same. The methods we define next conduct the individual text preprocessing needed.

  • TheChatterBot Corpus contains data that can be used to train chatbots to communicate.
  • They have all harnessed this fun utility to drive business advantages, from, e.g., the digital commerce sector to healthcare institutions.
  • Clear objectives will guide the development process and help you measure the chatbot’s success.
  • However, their code generation capabilities are limited compared to human programmers.
  • That‘s precisely why Python is often the first choice for many AI developers around the globe.

Which chatbot is not AI based?

Chatbots are a type of conversational AI, but not all chatbots are conversational AI. Rule-based chatbots use keywords and other language identifiers to trigger pre-written responses—these are not built on conversational AI technology.
