A Quick Guide to the Use of NLP in Chatbots

Building A Conversational N L.P Enabled Chatbot Using Googles Dialogflow

It is possible to establish a link between incoming human text and the system-generated response using NLP. This response can range from a simple answer to a query to an action based on a customer request or the storage of any information from the customer in the system database. Just define a new tag, possible patterns, and possible responses for the chat bot. Now that we have defined our attention submodule, we can implement the

actual decoder model. For the decoder, we will manually feed our batch

one time step at a time. This means that our embedded word tensor and

GRU output will both have shape (1, batch_size, hidden_size).

A chatbot using NLP will keep track of information throughout the conversation and learn as they go, becoming more accurate over time. In this section, you put everything back together and trained your chatbot with the cleaned corpus from your WhatsApp conversation chat export. At this point, you can already have fun conversations with your chatbot, even though they may be somewhat nonsensical. Depending on the amount and quality of your training data, your chatbot might already be more or less useful. Next, you’ll learn how you can train such a chatbot and check on the slightly improved results.

In our case we will implement a multiclass classifier using a neural network. Programming language- the language that a human uses to enable a computer system to understand its intent. Preprocessing plays an important role in enabling machines to understand words that are important to a text and removing those that are not necessary. With more organizations developing AI-based applications, it’s essential to use…


As technology and the human–computer interface progress, NLP usage and applications are attracting increasing attention, prompting widespread recognition and implementation in a variety of industries. NLP has found its use in the banking sector [1,2,3] in supply chains [4, 5] to education [6,7,8,9,10] within the legal space [11,12,13] and among medical practitioners [14, 15]. The combination of artificial intelligence (AI) and automation is causing significant changes in the business world. In order to reach previously unachievable levels of efficiency and quality, businesses are presently focusing their attention on developing new applications of AI and automating their work processes [16]. Several studies have shown that NLP can be used to comprehend and interpret speech or text in natural language to accomplish the desired goals [17,18,19,20,21].

In all of the phrases listed above, the name or type of food is not specified but rather they are all specified as food. This is because we want the food to be dynamic value, if we were to list all the food names we certainly would need to have a very large list of training phrases. This also applies to the amount and price of the food being ordered, they would be annotated and the agent would be able to recognize them as a placeholder for the actual values within an input.

  • This has led to a massive reduction in labor cost and increased the efficiency of customer interaction.
  • However, you’ll quickly run into more problems if you try to use a newer version of ChatterBot or remove some of the dependencies.
  • Determining which goal you want the NLP AI-powered chatbot to focus on before beginning the adoption process is essential.
  • Additionally, you can adjust your models and continue to train them as your industry or business terminology changes [25, 112].

ChatterBot uses the default SQLStorageAdapter and creates a SQLite file database unless you specify a different storage adapter. 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! You can always stop and review the resources linked here if you get stuck.

We can have a much more dynamic user experience with the Conversational Interface instead of just relying on the natural language interaction. We can take into considered Slack as an example, where the bit platform is getting interactive with big UI elements like images and push buttons and messaging menus. For example, the NLP processing model required for the processing of medical records might differ greatly from that required for the processing of legal documents.

It’s fast, ideal for looking through large chunks of data (whether simple text or technical text), and reduces translation cost. Don’t waste your time focusing on use cases that are highly unlikely to occur any time soon. You can come back to those when your bot is popular and the probability of that corner case taking place is more significant. On the other hand, if the alternative means presenting the user with an excessive number of options at once, NLP chatbot can be useful. It can save your clients from confusion/frustration by simply asking them to type or say what they want.

Channel and technology stack

To process these types of requests, based on user questions, chatbot needs to be connected to backend CRMs, ERPs, or company database systems. Intent classification means that a chatbot is able to understand what humans want. A restaurant customer service bot, for example, not only needs to be able to recognize if a customer wants to order a pizza or ask about the status of their delivery, but also what type of pizza they want. When a customer calls a restaurant to order a pizza, for instance, the service agent goes into the call with a lot of background knowledge. The agent knows what types of pizzas there are on the menu, what ingredients can be the agent also knows what questions customers typically ask, from delivery time to forms of payment.

Today, chatbots can consistently manage customer interactions 24×7 while continuously improving the quality of the responses and keeping costs down. Chatbots automate workflows and free up employees from repetitive tasks. A chatbot can also eliminate long wait times for phone-based customer support, or even longer wait times for email, chat and web-based support, because they are available immediately to any number of users at once.

We now just have to take the input from the user and call the previously defined functions. Now, we will extract words from patterns and the corresponding tag to them. This has been achieved by iterating over each pattern using a nested for loop and tokenizing it using nltk.word_tokenize. The words have been stored in data_X and the corresponding tag to it has been stored in data_Y.

To the contrary…Besides the speed, rich controls also help to reduce users’ cognitive load. Hence, they don’t need to wonder about what is the right thing to say or ask.When in doubt, always opt for simplicity. So, when logical, falling back upon rich elements such as buttons, carousels or quick replies won’t make your bot seem any less intelligent. These rules trigger different outputs based on which conditions are being met and which are not. ‍Currently, every NLG system relies on narrative design – also called conversation design – to produce that output. To nail the NLU is more important than making the bot sound 110% human with impeccable NLG.

No, that’s not a typo—you’ll actually build a chatty flowerpot chatbot in this tutorial! You’ll soon notice that pots may not be the best conversation partners after all. In this step, you’ll set up a virtual environment and install the necessary dependencies.

And these are just some of the benefits businesses will see with an NLP chatbot on their support team. Eventually, you’ll use cleaner as a module and import the functionality directly into bot.py. But while you’re developing the script, it’s helpful to inspect intermediate outputs, for example with a print() call, as shown in line 18. If you scroll further down the conversation file, you’ll find lines that aren’t real messages.
