1、PART1 Since World War II, computer scientists have tried to develop techniques that would allow computers to act more like humans. The entire research effort, including decision-making systems, robotic devices (Fig.22-1), and various approaches to computer speech, is usually called artificial intell

2、igence (AI). An ultimate goal of AI research is to develop a computer system that can learn concepts (ideas) as well as facts, make commonsense decisions, and do some planning. In other words, the goal is to eventually create a thinking, learning computer. A computer program is a set of instructions

3、 that enables a computer to process information and solve problems. Most programs are fairly rigidthey tell the computer exactly what to do, step by step. AI programs are, however, exceptions to this rule. They can take short-cuts, make choices, search for and try out different solutions, and change

4、 their methods of operation.

5、em. Ifthen rules of reasoning are also programmed in to enable the computer to select, organize, and update its information. According to these rules, if something is true, then certain things must follow. Every action makes new possible actions available. Programs to play chess have been around sin

6、ce the early days of electronic computers, but they tended to be rigid and limited by the skills of the program designer. Detailed instructions on what moves to make and how to respond to an opponents moves were written into a program. Sometimes the suggestions of several chess experts were included

7、. However, such programs seldom defeated human chess experts. The computer program would tend to be strong in the opening part of the game, but would weaken as the game went on.TextNew wordNotesExercisesTranslationVocabulary PART1Lesson 22 Artificial Intelligence(AI)TextNew wordNotesExercisesTransla

8、tionVocabulary Thanks to AI research, all that has changed. Recently, chess-playing computer programs have been developed to defeat most human opponentsincluding chess masters. Of course, theres more to artificial intelligence than the ability to play games. Computer scientists are working on dozens

9、 of different practical uses for AI programs. These included operating robots, solving math and science problems, understanding speech, and analyzing images. Perhaps the biggest use of AI programs is expert advisors for trouble-shooting (locating problems and making repairs) complex systems ranging

10、from diesel engines to nuclear submarines and to the human body. In other words, these AI programs search for trouble, detect and classify problem areas, and give advice. The use of AI expert advice systems will not be limited to trouble-shooting specific machinery. AI programs are being developed f

12、f laser sensors, AI techniques are being developed to analyze visual information and to improve robot capabilities. Most artificial intelligence systems involve some sort of integrated technologies, for example the integration of speech synthesis technologies with that of speech recognition. The cor

13、e idea of A.I. systems integration is making individual software components, such as speech synthesizers, interoperable with other components, such as common sense knowledge bases, in order to create larger, broader and more capable A.I. systems. The main methods that have been proposed for integrat
