| Summary | This course teaches the basic technologies required for text processing, focussing mainly on information retrieval and text classification. It gives a detailed overview of information retrieval and describes how search engines work. It also covers basic knowledge of the main steps for text classification.
This course is a highly practical course, where at least 50% of what is taught in the course will be implemented from scratch in course works and labs, and students are required to complete a final project in small groups. All lectures, labs, and two course works will take place in Semester 1. The final group project will be due early Semester 2 by week 3 or 4. |
| Course description |
Syllabus:
* Introduction to IR and text processing, system components
* Zipf, Heaps, and other text laws
* Pre-processing: tokenization, normalisation, stemming, stopping.
* Indexing: inverted index, boolean and proximity search
* Evaluation methods and measures (e.g., precision, recall, MAP, significance testing).
* Query expansion
* IR toolkits and applications
* Ranked retrieval and learning to rank
* Text classification: feature extraction, baselines, evaluation
* Web search

| Additional Information (Assessment) |
Exam 30%
Coursework 70%
Course Work 1 10%, individual work covers implementing basic search engine
Course Work 2 20%, individual work covering IR evaluation and web search
Course Work 3 40%, is a group project, where each group is 4-6 members
All of the coursework is heavy on system implementation, and thus being familiar with programming and software engineering is a pre-requisite. Python is required for implementation of Course Work 1 and Course Work 2. For Course Work 3, students are free to use the implementation language they prefer. |
