TITLE Data-Driven Natural Language Processing

 
LEVEL 03 - Years 2, 3, 4 in Modular Undergraduate Course

 
ECTS CREDITS 5

 
DEPARTMENT Institute of Linguistics and Language Technology

 
DESCRIPTION This study-unit focuses on techniques for designing Natural Language Processing applications whose core is a statistical model of language derived from large linguistic corpora. The unit is divided into three main parts, as follows:

1. Part I deals with introductory material and some of the mathematical and linguistic background. In this part, participants will also be introduced to existing corpora, as well as annotation methods.

2. Part II focuses in detail on particular areas of corpus-driven research in NLP, and the methods used, with particular emphasis on:
- Research on words, word distributions, word frequencies and collocations.
- Semantic similarity and corpus-derived thesauri.
- N-gram language models.
- Hidden Markov models.
- Maximum Entropy models.

3. Part III aims to provide a more comprehensive picture of state-of-the art NLP research, with emphasis on the areas such as the following:
- Part of speech tagging.
- Statistical Parsing.
- Statistical techniques for Natural Language Generation.

Study-unit Aims:

Contemporary NLP applications increasingly rely on statistical generalisations from data repositories to circumvent the knowledge bottleneck that has plagued AI systems since their inception. A knowledge of statistical methods and algorithms is therefore fundamental to any student of NLP. This unit aims to:
- Give students a thorough grounding in such methods.
- Show how these methods are deployed in the construction of systems for the robust analysis and generation of Natural Language.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:
- Identify the appropriate statistical models for a particular NLP problem.
- Design and implement a system that incorporates data-driven learning of natural language patterns.

2. Skills:

By the end of the study-unit the student will be able to:
- Formulate a research problem in probabilistic terms.
- Formulate and test hypotheses.
- Find and exploit resources (including web resources).
- Implement solutions to NLP problems using data-driven methods based on large corpora and stochastic models.
