Issues in Knowledge Representation
{"Image DocumentName": "Issues in Knowledge Representation", "Image ImageDescription": "Most of the issues in knowledge representation are motivated by the effort to program a computer to understand natural languages such as English. Issues raised: Exactly what things can be represented by the objects and relations in the language. E.g. if a predicate relates an object to a value, such as hascolour(car,red) how can that be used to represent John\u2019s car is redder than Mary\u2019s . What level of complexity is required for our objects. How do we distinguish between intensional and extensional knowledge? The intension determines what a concept means at an abstract level (ball is round). The extension is the set of all things denoted by the object (set of all balls). A database denotes the extension of the object, whereas an expert system includes the intension of the object.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
