how to build a chatbot using nlp

Chatbots play a vital role in the interaction with the users who need the information. There are many advantages of implementing a chatbot in any application/website based on the current situation. Numerous chatbots are already deployed and are serving the users, and are striving to fulfill user’s needs. The basic architecture of a chatbot is given to acknowledge the working of the chatbot. A case study has been made on the most widely used chatbot – Google Assistant.


NLP assists your chatbot in analyzing and producing text from human language. NLP is a subset of informatics, mathematical linguistics, machine learning, and metadialog.com AI. Let’s look at some of the most important aspects of natural language processing. To show you how easy it is to create an NLP chatbot, we’ll use Tidio.

More Efficient Service Means Happier Customers

To deal with this, you could apply additional preprocessing on your data, where you might want to group all messages sent by the same person into one line, or chunk the chat export by time and date. That way, messages sent within a certain time period could be considered a single conversation. All of this data would interfere with the output of your chatbot and would certainly make it sound much less conversational.

Best of all, these new queries and the responses are saved in Capacity, so the system is always learning. It, therefore, has the best response every time and is always improving with time. In this tutorial, we will guide you on how to build a chatbot using Go and natural language processing (NLP) techniques. A chatbot is a software application that can interact with users through text or voice messages. By implementing NLP, your chatbot can understand user input, process it, and generate human-like responses. Their NLP-based codeless bot builder uses a simple drag-and-drop method to build your own conversational AI-powered healthcare chatbot in minutes.

Python Chatbot Project-Learn to build a chatbot from Scratch

Congratulations, you’ve built a Python chatbot using the ChatterBot library! Your chatbot isn’t a smarty plant just yet, but everyone has to start somewhere. You already helped it grow by training the chatbot with preprocessed conversation data from a WhatsApp chat export. Your chatbot has increased its range of responses based on the training data that you fed to it.

  • It has a variety of applications in different areas like Medical Research, search engines, and business intelligence staff.
  • To extract the name of the city a loop is used to traverse all the entities that spaCy has extracted from the user input and check whether the entity label is “GPE” (Geo-Political Entity).
  • Without further ado, it will invite you to create the first intent for your agent.
  • NLP technologies have made it possible for machines to intelligently decipher human text and actually respond to it as well.
  • Unlike common word processing operations, NLP doesn’t treat speech or text just as a sequence of symbols.
  • In this section, you put everything back together and trained your chatbot with the cleaned corpus from your WhatsApp conversation chat export.

We thus have to preprocess our text before using the Bag-of-words model. Few of the basic steps are converting the whole text into lowercase, removing the punctuations, correcting misspelled words, deleting helping verbs. But one among such is also Lemmatization and that we’ll understand in the next section.

Step 2: Choosing the right channel and Technology stack for your chatbot.

The ChatLog text field’s state is always set to “Normal” for text inserting and afterwards set to “Disabled” so the user cannot interact with it. Chatbots are used a lot in customer interaction, marketing on social network sites and instantly messaging the client. Now we will lemmatize each word and remove duplicate words from the list. Lemmatizing is the process of converting a word into its lemma form and then creating a pickle file to store the Python objects which we will use while predicting. Here we iterate through the patterns and tokenize the sentence using nltk.word_tokenize() function and append each word in the words list. When working with text data, we need to perform various preprocessing on the data before design an ANN model.

  • It’s the twenty-first century, and computers have evolved into more than simply massive calculators.
  • Deep learning methods employ multiple processing layers to learn hierarchical representations of data, and have produced state-of-the-art results in many domains.
  • If you want to create a sophisticated chatbot with your own API integrations, you can create a solution with custom logic and a set of features that ideally meet your business needs.
  • This is especially important if you plan to leverage healthcare chatbots in your patient engagement and communication strategy.
  • Designers should also pay attention to both easy to handle close-ended conversations and open-ended conversations so that chatbots can communicate with customers more naturally.

Still, while contexts can be very useful, if you are building a simple linear dialogue, you might not need them at all. For instance, intent in Dialogflow can identify that the meaning of “Hi” is a “Greeting” and so decide on an appropriate response. In this sense, you can train your agent to differentiate between intent to find information, intent to buy, or intent to make a reservation.

NLP-powered chatbots are capable of understanding the intent behind conversations and then creating contextual and relevant responses for users. There are a number of human errors, differences, and special intonations that humans use every day in their speech. NLP technology allows the machine to understand, process, and respond to large volumes of text rapidly in real-time. In everyday life, you have encountered NLP tech in voice-guided GPS apps, virtual assistants, speech-to-text note creation apps, and other app support chatbots.
