Man and Computer{{/B}} 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 com puter, it might {{U}}(65) {{/U}} rise out of the "goal" to learn more about restaurants. |
