2001 fall semester

cse659 statistical natural language processing

instructor: Geunbae Lee, Eng 2-211, gblee@postech.ac.kr, 279-2254

language: English

1. Course objectives

This course introduces various recent statistical methods in natural language processing.
We will cover basic statistical tools for computational linguistics and their application to part-of-speech tagging,
statistical parsing, word sense disambiguation, machine translation, information retrieval and statistical discourse processing.
If time permits, we will briefly touch on some topics of statistical language models for speech recognition and text-to-speech systems.
