This course considers the “document” and its various genres as a fundamental object for business, government and community, such as web pages, social media feeds, news items, and PDF brochures. The goal is to introduce concepts and hands-on tools for automated understanding of large amounts of text. For this, the course covers four broad areas: (A) information retrieval, (B) natural language processing, © machine learning for documents, and (D) relevant tools for the web. Tasks include content collection and extraction, formal and informal natural language processing, information extraction, information retrieval, classification and analysis. Fundamental probabilistic techniques for performing these tasks, and some common software systems will be covered, though no area will be covered in great depth.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

1. differentiate between the basic probabilistic theories of language and document structure, information retrieval, and classification, clustering and document feature engineering.
2. identify the basic algorithms and software available for probabilistic theories of language and be proficient at using common libraries for natural language processing to perform basic analysis tasks.
3. index a document collection for use in an information retrieval system. Demonstrate advanced knowledge of basic theories and algorithms to determine large scale named-entity matching and standardization of names within a collection.
4. perform automated classification using probabilistic theories.

Research-Led Teaching

The teaching and learning activities below are founded on state-of-the-art research outcomes and currently ongoing research projects. For example, document analysis methods and applications are considered through the strategic Our Health In Our Hands (OHIOH) initiative of The ANU, created in partnership with ACT Health.

Required Resources

A laptop or desktop with a reliable internet connection is required for accessing the course material on Wattle and for completing the practicals and assignments. Python and Jupyter Notebook will be used extensively in this course so being able to install freely available software will be necessary. An alternative is to have access to a laptop or desktop where appropriate software is already installed.

Further details on software used, and instructions, can be found on the Wattle site for the course.

Recommended Resources

The following textbooks will help you to better understand the course material and broaden your understanding. They are both provided online for free by the authors and are highly recommended. The first book covers IR in a very approachable way, but it goes into much more depth than we will cover in this course. The second book is a currently evolving new edition of one of the best NLP textbooks. This book is up to date with the latest approaches and covers many topics in much greater depth than we will cover in this course.

Staff Feedback

Students will be given feedback in the following forms: 

• Written marks and feedback for the online quizzes on Wattle.
• Written marks and feedback on the assignments.
• Written marks and feedback for the final exam.
• Casual verbal feedback and comments during lectures and computing labs, supported by discussion forum posts.

Marks and feedback for assessment items, with the exception of the final exam, are retuned to students within 2 weeks from the respective submission dates, using Wattle grade books and/or Wattle quizzes. If you have questions related to your mark, you must contact Hanna Suominen within 14 days from the mark release. In accordance with the ANU examination policies, final exam marks are released only after the final marks for the entire unit have been released by the ANU.

Note that consistent scaling for each of the units may occur with the final marks. Students must get a minimum final overall mark of at least 50/100 (50%) to pass the subject. Final marks are moderated by the examiners' meeting at the School of Computing. Supplementary assessment will be awarded to those students with an overall unit mark of between 45 and 49.

Student Feedback

ANU is committed to the demonstration of educational excellence and regularly seeks feedback from students. Students are encouraged to offer feedback directly to their Course Convener or through their College and Course representatives (if applicable). The feedback given in these surveys is anonymous and provides the Colleges, University Education Committee and Academic Board with opportunities to recognise excellent teaching, and opportunities for improvement. The Surveys and Evaluation website provides more information on student surveys at ANU and reports on the feedback provided on ANU courses.

Other Information

Gen AI Tools are ALLOWED: 

The use of Generative AI Tools (e.g., ChatGPT) is permitted in this course, given that proper citation and prompts are provided, along with a description of how the tool contributed to the assignment. Guidelines regarding appropriate citation and use can be found on the ANU library website at https://libguides.anu.edu.au/generative-ai . Marks will reflect the contribution of the student rather than the contribution of the tools. Further guidance on appropriate use should be directed to the convener for this course.
