Course Summary

Knowledge Representation and Reasoning (KRR) is at the core of Artificial Intelligence. It is concerned with the representation of knowledge in symbolic form and the use of this knowledge for reasoning. This course presents current trends and research issues in Knowledge Representation and Reasoning (KRR). It enables students interested in Artificial Intelligence to deepen their knowledge in this important area and gives them a solid background for doing their own work/research in this area. The topics covered include: Commonsense reasoning, Propositional and First-order Logic, Answer set programming, Planning, Reasoning about action, Constraint programming.

This course can be a starting point for further exploration of artificial intelligence. Further courses include COMP3431/COMP9431: Robotic Software Architecture, COMP9417: Machine Learning and Data Mining, COMP9444: Neural Networks and COMP9844: Extended Neural Networks.

Required Knowledge

Students are expected to have some background in symbolic logic and general AI, which might come from COMP3411 or COMP9414: Artificial Intelligence or COMP9814: Extended Artificial Intelligence. The handbook entry (undergraduate) and handbook entry (postgraduate) require these as pre-requisites for this course. Students with a background in symbolic logic and/or artificial intelligence obtained by other means should contact Student Support Services to request a waiver for the pre-requisite.

Student Learning Outcomes

COMP4418 is focussed on current trends and issues in Knowledge Representation and Reasoning. The intent of this course is to connect students to the topics through lecturers who know their subjects intimately, through continuing active use and research. To this end, there are three lecturers, each with great expertise in the topics they present. The course is structured to keep related topics close together, and to develop some themes. Assessment is based around assignments, which supports "learning by doing" and a final written exam that will examine the material taught across the course.

As a result of this course, students will:

• develop an understanding of theoretical and practical issues in symbolic knowledge representation and reasoning, in general;
• develop an understanding of the capabilities of specific knowledge representation formalisms for specific tasks;
• learn techniques specific to specific knowledge representation problems and formalisms; and,
• have practical experience in using special-purpose languages for (some of) commonsense reasoning, ontologies, planning, reasoning about actions, and constraint programming.

Student Conduct

The Student Code of Conduct ( Information , Policy ) sets out what the University expects from students as members of the UNSW community. As well as the learning, teaching and research environment; the University aims to provide an environment that enables students to achieve their full potential and to provide an experience consistent with the University's values and guiding principles. A condition of enrolment is that students inform themselves of the University's rules and policies affecting them, and conduct themselves accordingly.

In particular, students have the responsibility to observe standards of equity and respect in dealing with every member of the University community. This applies to all activities on UNSW premises and all external activities related to study and research. This includes behaviour in person as well as behaviour on social media, for example Facebook groups set up for the purpose of discussing UNSW courses or course work. Behaviour that is considered in breach of the Student Code Policy as discriminatory, sexually inappropriate, bullying, harassing, invading another's privacy or causing any person to fear for their personal safety is serious misconduct and can lead to severe penalties, including suspension or exclusion from UNSW.

If you have any concerns, you may raise them with your lecturer, or approach the School Ethics Officer , Grievance Officer , or one of the student representatives.

Plagiarism is defined as using the words or ideas of others and presenting them as your own. UNSW and CSE treat plagiarism as academic misconduct, which means that it carries penalties as severe as being excluded from further study at UNSW. There are several on-line sources to help you understand what plagiarism is and how it is dealt with at UNSW:

• Plagiarism and Academic Integrity
• UNSW Plagiarism Procedure

Make sure that you read and understand these. Ignorance is not accepted as an excuse for plagiarism. In particular, you are also responsible that your assignment files are not accessible by anyone but you by setting the correct permissions in your CSE directory and code repository, if using. Note also that plagiarism includes paying or asking another person to do a piece of work for you and then submitting it as your own work.

UNSW has an ongoing commitment to fostering a culture of learning informed by academic integrity. All UNSW staff and students have a responsibility to adhere to this principle of academic integrity. Plagiarism undermines academic integrity and is not tolerated at UNSW. Plagiarism at UNSW is defined as using the words or ideas of others and passing them off as your own.

If you haven't done so yet, please take the time to read the full text of

• UNSW's policy regarding academic honesty and plagiarism

Course Evaluation and Development

This course is evaluated each session using the myExperience system.

Student feedback will be obtained by electronic survey at the end of the course through myExperience . Students are also encouraged to provide informal feedback during the session, and to let the Lecturer-in-Charge know of any problems as soon as they arise.

Student feedback from the last offering indicated that students were satisfied with the course, but suggested to include more guidance to the programming languages in the lectures. We will endeavour to achieve that in this offering.
