Guide to AI in customer service using chatbots and NLP

Now, since we can only compute errors at the output, we have to propagate this error backward to learn the correct set of weights and biases. If you want to follow along and try it out yourself, download the Jupyter notebook containing all the steps shown below. The necessary data files for this project are available from this folder. Make sure the paths in the notebook point to the correrct local directories. And of course, you will need to install all the Python packages if you do not have all of them yet.

The user needs enter a string which is like a welcome message or a greeting, the chatbot will respond accordingly. First, we need to install the required libraries for Developing a chatbot. NLTK, Regex, random and string libraries are required for chatbot development. In the above image, we have created a bow (bag of words) for each sentence. Basically, a bag of words is a simple representation of each text in a sentence as the bag of its words. Tokenize or Tokenization is used to split a large sample of text or sentences into words.

How to build the input for an NLP

While the data is logically valid, it is mostly concerned with the context of certain research questions. Numerous variables could have had an impact on the study’s accuracy such as data extraction process and studies focus. Five major scientific databases were searched at in order to retrieve the relevant studies. However, these databases are not exhaustive, and, as a result, the quality of this research may have been impacted.

Natural language processing (NLP) is a branch of artificial intelligence that helps computers understand, interpret, derive meaning, manipulate human language, and then respond appropriately. With the growing pace of technology, companies are now looking for better and more innovative ways to serve their customers. For the past few years, we’ll have been hearing about chat support systems provided by different companies in different domains. Be it food delivery, E-commerce, or Ticket booking, chatbots are almost everywhere now and they are the first communication on behalf of their brand. Nowadays, they’ve become somewhat necessary to the companies for smooth communication.

EXISTING USERS

The chatbot started from a clean slate and wasn’t very interesting to talk to. Chatbots can be available around the clock, providing assistance and information to users at any time, which is especially useful for global audiences. Define dialog classes for different flows and use them to manage user interactions. In its current iteration, NLP can be taught to answer a number of questions, some of which are rather complex. In the near future, however, NLP will be trained to do more than just answer questions; it will be able to deliver complicated solutions that directly address the underlying questions being asked. In the years to come, we can anticipate that NLP technology will become increasingly sophisticated and precise [104, 121, 122].

• They are able to respond and help with tasks like customer service or information retrieval since they can comprehend and interpret natural language inputs.
• Chatbots can make it easy for users to find information by instantaneously responding to questions and requests—through text input, audio input, or both—without the need for human intervention or manual research.
• Additionally, NLP can help businesses save money by automating customer service tasks that would otherwise need to be performed by human employees.
• Bizbike was able to increase their NPS score from 54 to 56, which means that 62 percent of their customers are actively promoting conversational chatbot solutions and the Bizbike service.

Many digital businesses tend to have a chatbot in place to compete with their competitors and make an impact online. You need to want to improve your customer service by customizing your approach for the better. Thus, rather than adopting a bot development framework or another platform, why not hire a chatbot development company to help you build a basic, intelligent chatbot using deep learning.

Much like any worthwhile tech creation, the initial stages of learning how to use the service and tweak it to suit your business needs will be challenging and difficult to adapt to. Once you get into the swing of things, you and your business will be able to reap incredible rewards, as a result of NLP. First we will create a function “utteranceToFeatures” than given a text (the utterance) will return the features object as the input of the example. The method chain is to build a pipeline of functions, and featuresToDict converts an array of features to the object format.

We would love to have you onboard to have a first-hand experience of Kommunicate. What we see with chatbots in healthcare today is simply a small fraction of what the future holds. This is the process by which you can break entire sentences into either words. The name of this process is word tokenization or sentences – whose name is sentence tokenization.

The final step in this process is called decision-making and this enables the chatbot to be more intelligent. This prepares the chatbot step ahead for expected questions and then the decision is modified depending on that. NLP is useful for many businesses, however customer service benefits the most. Individuals are actively researching and advancing technology as it serves businesses as well as consumers.

As more and more industries are predicted to engage with this technology, staying one step ahead by investing in it now will keep your business competitive. 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.

Additionally, the utilization of language translation techniques in order to eliminate linguistic barriers and automate the process of providing answers to customer queries in a diverse range of languages. The process of transforming spoken or written language from one language to another is called language translation. In customer query response, language translation can be used to automate the process of providing answers to customer queries in a diverse range of languages, which is useful in customer care and support.

‘Not another one of these,’ you sigh to yourself, recalling the frustrating and unnatural conversations, the robotic rhetoric, and often nonsensical responses you’ve had in the past when using them. You warily type in your search query, not expecting much, but to your surprise, the response you get is not only helpful and relevant; it’s conversational and engaging. It encourages you to stay on the page, to go ahead with your purchase, find out more about the business, sign up for repeat purchasing, or even buy further products. With personalization being the primary focus, you need to try and “train” your chatbot about the different default responses and how exactly they can make customers’ lives easier by doing so. With NLP, your chatbot will be able to streamline more tailored, unique responses, interpret and answer new questions or commands, and improve the customer’s experience according to their needs. It is also important to pause and wonder how chatbots and conversational AI-powered systems are able to effortlessly converse with humans.

Why NLP is a must for your chatbot

In this tutorial, you’ll start with an untrained chatbot that’ll showcase how quickly you can create an interactive chatbot using Python’s ChatterBot. You’ll also notice how small the vocabulary of an untrained chatbot is. Chatbots can provide immediate waiting times for users and improving overall satisfaction. Chatbots can handle a large number of simultaneous interactions, ensuring consistent and prompt responses regardless of the number of users. We used five digital libraries (ScienceDirect, Springer, Web of Science, Scopus, and IEEE) to perform an automatic search for research articles as an answer to inquiries about research from relevant journals and conferences. As a result of differing approaches taken by the numerous search engines in the pursuit of relevant articles, the total number of publishing results varied between databases.

For example, it is entirely feasible that the choice of existing studies or the assessment will be influenced by the assumptions of the researcher without a protocol [39]. Additionally, the establishment of a standardized protocol that others can use to replicate the study adds credibility to the review. The primary focus of the planning phase is the preparation of the research undertaking to be carried out in order to perform the SLR. It entails determining the review’s goal, developing relevant hypotheses according to established goals, and devising a thorough review methodology. A systematic review approach should be employed if the review’s primary goal is to assess and compile data showing how a certain criterion has an impact [59].

NLP is used to extract feelings like sadness, happiness, or neutrality. It is mostly used by companies to gauge the sentiments of their users and customers. By understanding how they feel, companies can improve user/customer service and experience. Chatbots help businesses to scale up operations by allowing them to reach a large number of customers at the same time as well as provide 24/7 service. They also offer personalized interactions to every customer which makes the experience more engaging.
