Text is unstructured data, meaning it is information that has no pre-set data structure or schema. Therefore it can't be stored, related, and measured in the same way structured data can.
However, if analyzed correctly, it can provide a wealth of insights that other data can’t. Fortunately, Natural Language Processing and Machine Learning can help you transform it into a structure so you can measure, quantify, and ultimately act on it.
This is what Classifiers do in Caravel.
A classifier can be a topic, expressed intent, emotion, sentiment, category, etc. that you want to predict from your text. Caravel then classifies your unstructured text using the classifiers that you've defined to give your text structure and quantify it.
In Caravel there are two types of classifiers: Prebuilt Classifiers and Custom Classifiers.
Prebuilt classifiers require zero training or setup and can be used right away to classify your text. Caravel offers classifiers that cover a myriad of categories from emotions to software bugs and topics for product, customer experience, eCommerce teams and more.

Custom classifiers are trainable and you can give them feedback to learn to predict custom topics or intents on your data. Our custom classifiers are meant to provide accuracy with small sets of training data, meaning you can get good results without spending much time training.
