Guide to AI in customer service using chatbots and NLP

NLP techniques are helping companies connect with their customers better, understand how they feel, and improve customer satisfaction across the board. The availability of automated customer service is not affected by schedules or locations. This allows businesses to provide ongoing customer care so that problems can be resolved as soon as they emerge. This enables customers to have their questions answered at any time without having to wait for a response, which could take anything from a few hours to several days—a significant impact on the level of customer satisfaction. Furthermore, it shows that the business is focused on providing service to customers, which is an asset for the general reputation of the brand and trust [80, 111]. Specifically, we intend to conduct a systematic literature review on automating customer queries through the use of several NLP techniques.

• Vector space models provide a way to represent sentences from a user into a comparable mathematical vector.
• It’ll help you create a personality for your chatbot, and allow it the ability to respond in a professional, personal manner according to your customers’ intent and the responses they’re expecting.
• 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.
• BUT, when it comes to streamlining the entire process of bot creation, it’s hard to argue against it.

To understand this just imagine what you would ask a book seller for example — “What is the price of __ book? ” Each of these italicised questions is an example of a pattern that can be matched when similar questions appear in the future. The source code to the JavaScript webhook built within this article has been pushed to GitHub and can be accessed from this repository. Using the command above deploys the function to the Google Cloud with the flags explained below attached to it and logs out a generated URL endpoint of deployed cloud function to the terminal. When at the entities tab, we name this new entity as food then at the options dropdown located at the top navigation bar beside the Save button we have the option to switch the entities input to a raw edit mode.

My journey of creating a personalized chatbot

Using mini-batches also means that we must be mindful of the variation [newline]of sentence length in our batches. To accommodate sentences of different

sizes in the same batch, we will make our batched input tensor of shape

(max_length, batch_size), where sentences shorter than the

max_length are zero padded after an EOS_token. For this we define a Voc class, which keeps a mapping from words to

indexes, a reverse mapping of indexes to words, a count of each word and

a total word count. The class provides methods for adding a word to the [newline]vocabulary (addWord), adding all words in a sentence

(addSentence) and trimming infrequently seen words (trim). The following functions facilitate the parsing of the raw [newline]utterances.jsonl data file.

This use case showcases how AI can be leveraged to create intelligent conversational agents that provide users with personalized and contextually relevant interactions. Following these steps, you can develop a sophisticated chatbot that understands user intent and engages in meaningful conversations. Intelligence in modern ChatbotsThe chatbots which are designed to be deployed in businesses and companies come in two varieties. The second type is based on machine learning model, where the bot actually focuses on understanding the context of the conversation to come up with solutions. The chatbot tries to figure the intention of the user behind the statement to formulate an effective response. This completely relies on training the model on a neural network which thinks on its own after being provided with a thousand examples.

Service chatbots

For now, we still cannot make use of the running function as Dialogflow only supports secure connections with an SSL certificate, and where Ngrok comes into the picture. After installing the needed packages, we modify the generated package.json file to include two new objects which enable us to run a cloud function locally using the Functions Framework. Moving on to the Training Phrases section on the intent page, we will add the following phrases provided by the end-user in order to find out which meals are available. After the context section is the intent’s Events and we can see it has the Welcome event type added to the list of events indicating that this intent will be used first when the agent is loaded.

Another way to extend the chatbot is to make it capable of responding to more user requests. For this, you could compare the user’s statement with more than one option and find which has the highest semantic similarity. SpaCy’s language models are pre-trained NLP models that you can use to process statements to extract meaning. You’ll be working with the English language model, so you’ll download that. In this step, you will install the spaCy library that will help your chatbot understand the user’s sentences.
