Course objective : The purpose of this course is to give students an understanding of various aspects of knowledge-based systems (KBS). This course will also facilitate students to engage in KBS related research topics.
Learning outcomes : A student completing the course successfully will Understand the principles by which the KBS work. Have an understanding of different methodologies of KBS and apply these concepts to implement KBS. Identify and categorize the problems for which a KBS approach would be appropriate. Be familiar with a range of KBS applications and with some KBS development tools.
Course content : Foundations of Knowledge-Based Systems, Propositional and predicate logic, Knowledge representation, Methods of inference and reasoning, Rule-based systems, Semantic networks and frames, Object-based systems, Search structures, Representing uncertainty, Reasoning under uncertainty, Approximate reasoning and fuzzy logic, Hybrid systems, Knowledge acquisition, Alternative approaches in reasoning: case-based reasoning, model-based reasoning, KBS development tools, KBS applications.
