Text Analytics: Machine Learning for Text

Text Analytics: Machine Learning for Text

Course Description

Text analytics is about the extraction of useful knowledge from texts. The ubiquity of texts in Web, social networks, emails, and digital libraries makes the need for the text processing approaches imperative. In recent years, leveraging machine learning methods for analyzing texts has received a lot of attention. But, what makes learning from texts specific? How should texts be represented for machine learning models? How can machine learning models discover hidden semantic information within a text?

This seminar is going to answer these questions by coherently introducing various text-centric machine learning approaches from basic algorithms (e.g. rule-based) to advanced models (e.g., deep neural networks). The seminar covers a wide spectrum of fascinating topics such as text clustering, text classification, heterogeneous data, and feature selection. We discuss exciting applications of these approaches. Examples include information extraction, text summarization, sentiment analysis, and text segmentation. By the end of this seminar, students gain the knowledge of how to apply machine learning approaches to solve text-centric problems.
