25+ Best Machine Learning Datasets for Chatbot Training in 2023

The dialogues are really helpful for the chatbot to understand the complexities of human nature dialogue. As the name says, these datasets are a combination of questions and answers. An example of one of the best question-and-answer datasets is WikiQA Corpus, which is explained below.

I pegged every intent to have exactly 1000 examples so that I will not have to worry about class imbalance in the modeling stage later. In general, for your own bot, the more complex the bot, the more training examples you would need per intent. To make sure that the chatbot is not biased toward specific topics or intents, the dataset should be balanced and comprehensive. The data should be representative of all the topics the chatbot will be required to cover and should enable the chatbot to respond to the maximum number of user requests. In this article, we’ll provide 7 best practices for preparing a robust dataset to train and improve an AI-powered chatbot to help businesses successfully leverage the technology.

1. Partner with a data crowdsourcing service

The decoder RNN generates the response sentence in a token-by-token

fashion. It uses the encoder’s context vectors, and internal hidden

states to generate the next word in the sequence. It continues

generating words until it outputs an EOS_token, representing the end

of the sentence. A common problem with a vanilla seq2seq decoder is that

if we rely solely on the context vector to encode the entire input

sequence’s meaning, it is likely that we will have information loss.

The chats are about topics related to the Semantic Web, such as RDF, OWL, SPARQL, and Linked Data. You can also use this dataset to train chatbots that can converse in technical and domain-specific language. This dataset contains over three million tweets pertaining to the largest brands on Twitter. You can also use this dataset to train chatbots that can interact with customers on social media platforms. That’s why your chatbot needs to understand intents behind the user messages (to identify user’s intention).


It can cause problems depending on where you are based and in what markets. Many customers can be discouraged by rigid and robot-like experiences with a mediocre chatbot. Solving the first question will ensure your chatbot is adept and fluent at conversing with your audience. A conversational chatbot will represent your brand and give customers the experience they expect. For example, consider a chatbot working for an e-commerce business.

After typing our input sentence and pressing Enter, our text

is normalized in the same way as our training data, and is ultimately

fed to the evaluate function to obtain a decoded output sentence. We

loop this process, so we can keep chatting with our bot until we enter

either “q” or “quit”. In order to quickly resolve user requests without human intervention, chatbots need to take in a ton of real-world conversational training data samples. Without this data, you will not be able to develop your chatbot effectively. This is why you will need to consider all the relevant information you will need to source from—whether it is from existing databases (e.g., open source data) or from proprietary resources.

However, if you’re interested in speeding up training and/or would like

to leverage GPU parallelization capabilities, you will need to train

with mini-batches. 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

vocabulary (addWord), adding all words in a sentence

(addSentence) and trimming infrequently seen words (trim). As for this development side, this is where you implement business logic that you think suits your context the best.

Therefore, the existing chatbot training dataset should continuously be updated with new data to improve the chatbot’s performance as its performance level starts to fall. The improved data can include new customer interactions, feedback, and changes in the business’s offerings. Chatbots leverage natural language processing (NLP) to create and understand human-like conversations.

When trained, these

values should encode semantic similarity between similar meaning words. Note that we are dealing with sequences of words, which do not have

an implicit mapping to a discrete numerical space. Thus, we must create

one by mapping each unique word that we encounter in our dataset to an

index value. This allowed the client to provide its customers better, more helpful information through the improved virtual assistant, resulting in better customer experiences.

Try not to choose a number of epochs that are too high, otherwise the model might start to ‘forget’ the patterns it has already learned at earlier stages. Since you are minimizing loss with stochastic gradient descent, you can visualize your loss over the chatbot training dataset epochs. Moreover, it can only access the tags of each Tweet, so I had to do extra work in Python to find the tag of a Tweet given its content. If you already have a labelled dataset with all the intents you want to classify, we don’t need this step.

In both cases, human annotators need to be hired to ensure a human-in-the-loop approach. For example, a bank could label data into intents like account balance, transaction history, credit card statements, etc. In order to create a more effective chatbot, one must first compile realistic, task-oriented dialog data to effectively train the chatbot. Without this data, the chatbot will fail to quickly solve user inquiries or answer user questions without the need for human intervention. Break is a set of data for understanding issues, aimed at training models to reason about complex issues.

The chatbot’s training dataset (set of predefined text messages) consists of questions, commands, and responses used to train a chatbot to provide more accurate and helpful responses. This dataset contains different sets of question and sentence pairs. They collected these pairs from Bing query logs and Wikipedia pages.

You can use this dataset to train chatbots that can adopt different relational strategies in customer service interactions. You can download this Relational Strategies in Customer Service (RSiCS) dataset from this link. This collection of data includes questions and their answers from the Text REtrieval Conference (TREC) QA tracks. These questions are of different types and need to find small bits of information in texts to answer them. You can try this dataset to train chatbots that can answer questions based on web documents. When

called, an input text field will spawn in which we can enter our query
