Knowledge Representation in Artificial Intelligence

Introduction to Knowledge Representation Knowledge representation is the used in artificial intelligence to represents complex information in a form that a computer system can solve in a simple way such as diagnosing a medical condition or having a dialog in a natural language. The term knowledge means body of facts and principles. It can be language, concepts, procedures, rules, ideas, abstractions, places, customs, and so on. It is an abstract term that means an individual understanding of a given subject. Knowledge is the information that can be used to solve problem in particular domain. To solve that kind of problems it requires more knowledge and this knowledge must be represented in the computer. To solve these types of problem by designing a program firstly it must define how the knowledge will be represented. It is a major issue for building expert system. Text, images, audio, video and different...

Expert System in Artificial Intelligence

INTRODUCTION An Expert system is a set of programs that manipulate encoded knowledge to solve problem in a specialized domain that normally requires human expertise. Expert system is part of computer application known as artificial intelligence. An expert system can perform a task which is performed by human expert. For example there are three expert system that can diagnose illness, financial forecast. Some expert system is designed to work as human experts while others are designed to help the expert system. It converts the specific subject into software code and these codes are used to answering question. The expert knowledge must be obtained from specialist or in other words expertise. It is divided into two sub system and these two sub system are: Knowledge base Inference engine Knowledge base It is a core module of an expert system and represents fact and rules in expert system. It...

Introduction to Artificial Intelligence

Introduction to AI Artificial Intelligence, or A.I., is a machine with some intelligent properties such as reasoning, planning and learning. The term Artificial Intelligence was introduced in 1956 by John McCarthy at the Massachusetts Institute of technology. Artificial Intelligence is a branch of computer science that can perform human types or human like operation. It is generally associated with computer science that concerned with the study and creation of computer system that exhibit some form of intelligence. A good example of artificial intelligence is face recognition. System that can learn new concepts and tasks. System that can reason and draw useful conclusion about the world around us. System that can understand natural language or precede and comprehend a visual scene. System that can perform other types of feats that require human type of intelligence. Artificial intelligence includes Neural Network Expert System Games Playing Natural Language Robotics Turing Test Fuzzy logic Logic Programming     Neural Network A neural network is also known as artificial...
