NLP chatbots A Complete guide by Freshchat

Recall that if an error is returned by the OpenWeather API, you print the error code to the terminal, and the get_weather() function returns None. In this code, you first check whether the get_weather() function returns None. If it doesn’t, then you return the weather of the city, but if it does, then you return a string saying something went wrong. The final else block is to handle the case where the user’s statement’s similarity value does not reach the threshold value. On the next line, you extract just the weather description into a weather variable and then ensure that the status code of the API response is 200 (meaning there were no issues with the request).

Widely used by service providers like airlines, restaurant booking apps, etc., action chatbots ask specific questions from users and act accordingly, based on their responses. 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. NLP chatbots also enable you to provide a 24/7 support experience for customers at any time of day without having to staff someone around the clock.

What is Natural Language Processing (NLP)?

This is especially important if you plan to leverage healthcare chatbots in your patient engagement and communication strategy. Once the intent has been differentiated and interpreted, the chatbot then moves into the next stage – the decision-making engine. Based on previous conversations, this engine returns an answer to the query, which then follows the reverse process of getting converted back into user comprehensible text, and is displayed on the screens. Say you have a chatbot for customer support, it is very likely that users will try to ask questions that go beyond the bot’s scope and throw it off. This can be resolved by having default responses in place, however, it isn’t exactly possible to predict the kind of questions a user may ask or the manner in which they will be raised. NLP is used to extract feelings like sadness, happiness, or neutrality.

Some common examples include WhatsApp and Telegram chatbots which are widely used to contact customers for promotional purposes. The cost-effectiveness of chatbots has encouraged businesses to develop their own. This has led to a massive reduction in labor cost and increased the efficiency of customer interaction.

To do this, you loop through all the entities spaCy has extracted from the statement in the ents property, then check whether the entity label (or class) is “GPE” representing Geo-Political Entity. If it is, then you save the name of the entity (its text) in a variable called city. Setting a low minimum value (for example, 0.1) will cause the chatbot to misinterpret the user by taking statements (like statement 3) as similar to statement 1, which is incorrect. Setting a minimum value that’s too high (like 0.9) will exclude some statements that are actually similar to statement 1, such as statement 2.

Apart from the applications above, there are several other areas where natural language processing plays an important role. For example, it is widely used in search engines where a user’s query is compared with content on websites and the most suitable content is recommended. The reality is that AI has been around for a long time, but companies like OpenAI and Google have brought a lot of this technology to the public. Of this technology, NLP chatbots are one of the most exciting AI applications companies have been using (for years) to increase customer engagement.

Preprocess data

In this article, we will create an AI chatbot using Natural Language Processing (NLP) in Python. First, we’ll explain NLP, which helps computers understand human language. Then, we’ll show you how to use AI to make a chatbot to have real conversations with people. Finally, we’ll talk about the tools you need to create a chatbot like ALEXA or Siri.

Naturally, predicting what you will type in a business email is significantly simpler than understanding and responding to a conversation. Simply put, machine learning allows the NLP algorithm to learn from every new conversation and thus improve itself autonomously through practice. The words AI, NLP, and ML (machine learning) are sometimes used almost interchangeably.

Create JSON of intent

In this section, you will create a script that accepts a city name from the user, queries the OpenWeather API for the current weather in that city, and displays the response. Test data is a separate set of data that was not previously used as a training phrase, which is helpful to evaluate the accuracy of your NLP engine. During training you might tell the new Home Depot hire that “these types of questions relate to pricing requests”, or “these questions are relating to the soil types we have”. A vast majority of these requests will fall into different buckets, or “intents”.

It’s vital to understand your organization’s needs and evaluate your options to ensure you select the AI solution that will help you achieve your goals and realize the greatest benefit.

With more organizations developing AI-based applications, it’s essential to use… Another way to compare is by finding the cosine similarity score of the query vector with all other vectors. In the above sparse matrix, the number of rows is equivalent to the number of sentences and the number of columns is equivalent to the number of words in the vocabulary. Every member of the matrix represents the frequency of each word present in a sentence. It is written in Cython and can perform a variety of tasks like tokenization, stemming, stop word removal, and finding similarities between two documents. NLP is used to summarize a corpus of data so that large bodies of text can be analyzed in a short period of time.

It provides the necessary information for the chatbot to understand and respond to user queries effectively. Gathering diverse and high-quality training data is essential to train a robust NLP model. By utilizing a combination of supervised and unsupervised learning techniques, NLP models can be trained to handle a wide range of user inputs and generate relevant responses. According to Google, their advanced NLP models achieved a 20% reduction in error rates compared to previous models. This advancement allows chatbots to better comprehend user intents and deliver more relevant responses. In this guide, one will learn about the basics of NLP and chatbots, including the fundamental concepts, techniques, and tools involved in building them.
