Text Analytics: Statistical Methods in NLP

Description

This course introduces some of the central themes and techniques that have emerged in statistical methods for language technologies and natural language processing. While many early NLP systems relied heavily on hand-crafted rules, during the past ten years a great deal of progress has been made using probabilistic methods that automatically and implicitly learn about language by extracting statistics from large quantities of text, thus reducing the knowledge acquisition bottleneck. As the computational power of computers increases, and as more natural language data becomes available online, statistical methods will become increasingly attractive and powerful in the future.

The seminar provides detailed coverage of current techniques, their strengths and limitations, and current research directions by including recent research papers. In the course of the seminar, students will acquire key skills like the fundamentals in academic research and scientific writing, and they will be encouraged to improve their presentation skills.
