GoalsIntroduction (KBS)Example Applications Alexander Felfernig & Gerald SteinbauerInstitute for Software TechnologyNr. Wissensverarbeitung

What is a KBS?A Knowledge-based System (KBS) is a system implemented with the goal to imitate human problem-solving behavior using Artificial Intelligence (AI) techniques.Development and maintenance of KBS is the objective of Knowledge Engineering (KE).Many commonalities with Software Engineering (SE).

Artificial Intelligence?Artificial intelligence (AI) research is concerned with the automation of tasks requiring intelligent behavior.Strong AI supposes that it is possible for machines to become sapient, or self-aware, but may or may not exhibit human-like thought processes.Weak AI supports the accomplishment of specific problem solving tasks not encompassing the full range of human cognitive abilities.
