Operational test for intelligent behavior
Computer should be interrogated by a human
Computer should possess:
Natural language processing (to communicate) – knowledge representation (to
store information) – automated reasoning (to answer questions and draw new
conclusion) – machine learning (to adapt new circumstances and to detect and
extrapolate patterns)
