Building a Chatbot using Chatterbot in Python

Now comes the final and most interesting part of this tutorial. We will compare the user input with the base sentence stored in the variable weather and we will also extract the city name from the sentence given by the user. Paste the code in your IDE and replace your_api_key with the API key generated for your account.

These chatbots employ cutting-edge artificial intelligence techniques that mimic human responses. Chatterbot combines a spoken language data database with an artificial intelligence system to generate a response. It uses TF-IDF (Term Frequency-Inverse Document Frequency) and cosine similarity to match user input to the proper answers. Once the dependence has been established, we can build and train our chatbot. We will import the ChatterBot module and start a new Chatbot Python instance.

Step 5: Running the Chatbot

By the end of this tutorial, you will have a basic understanding of chatbot development and a simple chatbot that can respond to user queries. ChatterBot is a library in python which generates responses to user input. It uses a number of machine learning algorithms to produce a variety of responses. It becomes easier for the users to make chatbots using the ChatterBot library with more accurate responses.

With further training, this chatbot can achieve better conversational skills and output more relevant answers. In the last step, we have created a function called ‘start_chat’ which will be used to start the chatbot. In the above image, we have imported all libraries. In the first step only we have to import the JSON data which contains rules using which we have to train our NLP model. We have also created empty lists for words, classes, and documents.

Pre-Requisites for creating a chatbot in Python

These chatbots are designed to simulate human conversation, and can be used to provide customer service, marketing, or even just entertainment. So it’s telling me now that it cannot provide real-time updates, but it’s known to be in a hot desert climate. You can see that this messages list is growing, and now it’s including all of the previous conversations. So it starts with the initial one, and then it’s adding all the responses. So essentially, we need to be running all of this code for as long as the conversation is taking place.

The demand for this technology surpasses the available intellectual supply. The first and foremost thing before starting to build a chatbot is to understand the architecture. For example, how chatbots communicate with the users and model to provide an optimized output. Let’s move further to the training stage of our bot creation process.

The num_beams parameter is responsible for the number of words to select at each step to find the highest overall probability of the sequence. We also should set the early_stopping parameter to True (default is False) because it enables us to stop beam search when at least `num_beams` sentences are finished per batch. This model is based on the same idea of passing the previous information through all network layers. The only difference is the complexity of the operations performed while passing the data. The network consists of n blocks, as you can see in Figure 2 below.

Artificial Intelligence is a field that is proving to be very healthy and productive in various areas. A Chatbot is one of its results that allows humans to get their answers through bots. It is one of the successful strategies to grab customers’ attention and provide them with the most impactful output.

Additionally, ChatterBot provides a simple interface for training the chatbot on custom datasets, allowing developers to tailor the chatbot to their specific needs. Overall, ChatterBot is a powerful tool for creating chatbots that can provide value to businesses and enhance the customer experience. Having completed all of that, you now have a chatbot capable of telling a user conversationally what the weather is in a city. The difference between this bot and rule-based chatbots is that the user does not have to enter the same statement every time. Instead, they can phrase their request in different ways and even make typos, but the chatbot would still be able to understand them due to spaCy’s NLP features.

This information (of gathered experiences) allows the chatbot to generate automated responses every time a new input is fed into it. Are you fed up with waiting in long lines to speak with a customer support representative? Can you recall the last time you interacted with customer service?

Once you have your chatbot up and running, it’ll be able to handle simple tasks and conversations. If you want to take your chatbot to the next level, you can consider adding more features or connecting it to other services. The chatbot will use the OpenWeather API to tell the user what the current weather is in any city of the world, but you can implement your chatbot to handle a use case with another API. Self-learning chatbots are an important tool for businesses as they can provide a more personalized experience for customers and help improve customer satisfaction. You can create Chatbot using Python with the help of its NLTK library.

The model will then predict the tag of the user’s message, and we will randomly select the response from the list of responses in our intents file. To train the model, we will convert each input pattern into numbers. First, we will lemmatize each word of the pattern and create a list of zeroes of the same length as the total number of words. We will set value 1 to only those indexes that contain the word in the patterns.

In fact, you might learn more by going ahead and getting started. You can always stop and review the resources linked here if you get stuck. A fork might also come with additional installation instructions. In other words, we need to tell Flask what to do when a specific address is called. To complete this tutorial, you will need Python 3 installed on your system as well as Python coding skills.

  • So, here you go with the ingredients needed for the python chatbot tutorial.
  • Natural Language Processing (NLP) is a subfield of artificial intelligence that focuses on the interaction between computers and humans through natural language.
  • Building a chatbot can be a challenging task, but with the right tools and techniques, it can be a fun and rewarding experience.
  • This URL returns the weather information (temperature, weather description, humidity, and so on) of the city and provides the result in JSON format.
  • Python is a popular choice for creating various types of bots due to its versatility and abundant libraries.

Unsure about which type of chatbot best fits your business goals? You can also add more functionalities to the bot by exploring the Telegram APIs. Next, we fetch the horoscope using the get_daily_horoscope() function and construct our message. Let’s create a utility function to fetch the horoscope data for a particular day.

The chatbot can be integrated in Telegram groups and channels, and it also works on its own. Artificial intelligence has brought numerous advancements to modern businesses. One such advancement is the development of chatbots — programs that solve various tasks via automated messaging. Here is another example of a Chatbot Using a Python Project in which we have to determine the Potential Level of Accident Based on the accident description provided by the user. Also, created an API using the Python Flask for sending the request to predict the output. In the above example, we have successfully created a simple yet powerful semi-rule-based chatbot.
