How To Create an Intelligent Chatbot in Python Using the spaCy NLP Library

With this output vector o, the weight matrix W, and the embedding of the question u, we can finally calculate the predicted answer a hat. The following figure shows the performance of RNN vs Attention models as we increase the length of the input sentence. When faced with a very long sentence, and ask to perform a specific task, the RNN, after processing all the sentence will have probably forgotten about the first inputs it had. I am a final year undergraduate who loves to learn and write about technology.

This not only elevates the user experience but also gives businesses a tool to scale their customer service without exponentially increasing their costs. As a cue, we give the chatbot the ability to recognize its name and use that as a marker to capture the following speech and respond to it accordingly. This is done to make sure that the chatbot doesn’t respond to everything that the humans are saying within its ‘hearing’ range.

Using .train() injects entries into your database to build upon the graph structure that ChatterBot uses to choose possible replies. If you’re comfortable with these concepts, then you’ll probably be comfortable writing the code for this tutorial. If you don’t have all of the prerequisite knowledge before starting this tutorial, that’s okay!

Now we have an immense understanding of the theory of chatbots and their advancement in the future. Let’s make our hands dirty by building one simple rule-based chatbot using python for ourselves. These chatbots require knowledge of NLP, a branch of artificial Intelligence (AI), to design them. They can answer user queries by understanding the text and finding the most appropriate response. The next step in the process consists of the chatbot differentiating between the intent of a user’s message and the subject/core/entity. In simple terms, you can think of the entity as the proper noun involved in the query, and intent as the primary requirement of the user.

Implement The NLP Utils¶

With the addition of more channels into the mix, the method of communication has also changed a little. Consumers today have learned to use voice search tools to complete a search task. Since the SEO that businesses base their marketing on depends on keywords, with voice-search, the keywords have also changed. Chatbots are now required to “interpret” user intention from the voice-search terms and respond accordingly with relevant answers.

• ChatterBot 1.0.4 comes with a couple of dependencies that you won’t need for this project.
• However, with more training data and some workarounds this could be easily achieved.
• I will also provide an introduction to some basic Natural Language Processing (NLP) techniques.
