etcML provides easy-to-use access to high-quality machine learning algorithms that can induce meaningful structure from your textual data. Our primary mode of analysis is classification, which you can think of as automatic categorization.
The input data - often referred to as training data - to our system is text, where each piece of text (usually a sentence or a document) has a predefined label. The system learns which labels are statistically associated with which kinds of words, and then can use that information to make accurate predictions about new, unlabeled data.
For example, we used the text of several thousands of online movie reviews as the training data for our sentiment classifier. We treated the star rating assigned to each review as its label, and had the system learn which kinds of words are associated with positive reviews, and which are associated with negative reviews. You can try typing in a positive or negative sentence, and the classifier will make a prediction about how likely it is that your sentence is expressing positive or negative sentiment.etcml
