Man and Computer What makes people different from computer programs? What is the missing element that our theories don't yet{{U}} (51) {{/U}}for? The answer is simple: People read newspaper stories {{U}}(52) {{/U}}a reason to learn more about what they are interested in. Computers, on the other hand, don't. In fact, computers don't{{U}} (53) {{/U}}have interests; there is nothing in particular that they are trying to find out when they read. If a computer{{U}} (54) {{/U}}is to be a model of story understanding, it should also read for a "purpose". Of course, people have several goals that do not make{{U}} (55) {{/U}}to attribute to computers. One might read a restaurant guide in order to satisfy hunger or entertainment goals, or to {{U}}(56) {{/U}}a good place to go for a business lunch. Computers do not{{U}} (57) {{/U}}, and computers do not have business lunches. However, these physiological and social goals give{{U}} (58) {{/U}}to several intellectual or cognitive(认知的)goals. A goal to satisfy hunger gives rise to goals to find{{U}} (59) {{/U}}about the name of a restaurant which serves the desired type of food, how expensive the restaurant is, the {{U}}(60) {{/U}}of the restaurant, etc. These are goals to{{U}} (61) {{/U}}information or knowledge, what we are calling{{U}} (62) {{/U}}goals. These goals can be held by computers too a computer might "want" to find out the location of a restaurant, and read a guide in order to do so{{U}} (63) {{/U}}the same way as a person might. While such a goal would not{{U}} (64) {{/U}}out of hunger in the case of the computer, it might{{U}} (65) {{/U}}rise out of the "goal" to learn more about restaurants. |
