Xomnia is a word combining the letter ‘X’ – the unknown – and “Omnia” – Latin for everything. Our team of data scientists and big data engineers are trained to find the undefined – X – in all the relevant data sources – Omnia. This unknown – X – is untapped business value. Combining the X and Omnia you get the Xomnia spirit. Eager, curious and dedicated people, who have the belief that the future is big data.

Introduction to Text Mining

Language is the core of human communication, so it’s no surprise that a lot of data comes in the form of text. Customer emails, feedback forms, documents and reports; all of these data sources contain useful textual information. Text mining techniques allow you to turn text data into useful insights quickly, for example by detecting customer sentiment or identifying important topics and keywords.

In this course, you will learn about the challenges of working with text data. You will learn how to preprocess text using pandas, and how to perform statistical text analysis techniques such as tf-idf. At the end of the course, you will be able to apply familiar supervised learning algorithms to the preprocessed data to perform tasks such as sentiment analysis and topic recognition.
