Outline 1 Representation systems Categories and objects . We will discuss two different systems that are commonly used to represent knowledge in machines The idea of constructing systems that perform their tasks by reasoning with explicitly represented knowledge is just a working hypothesis about how to Default Logic is an important method of knowledge representation and reasoning, because it supports reasoning with incomplete information, and because defaults can be found naturally in many application domains, such as diagnostic problems, information retrieval, legal reasoning, regulations, specifications . Prior exposure to relevant topics in theoretical computer science and AI, particularly knowledge representation and reasoning, is an advantage, but certainly not a requirement. Decision Support combining Machine Learning, Knowledge Representation and Case-Based Reasoning . Knowledge Representation and Reasoning (KR) is a well-established and lively field of research. knowledge representation, focusing on COMET (Bosselut et al.,2019), a language model trained on commonsense knowledge graphs. A crucial part of these systems is that knowledge is represented symbolically, and that reasoning procedures are able to extract .
