ARTIFICIAL INTELLIGENCE



Artificial intelligence (AI) is an area of research that goes back to the very beginnings of computer science. The idea of building a machine that can perform tasks perceived as requiring human intelligence is an attractive one. The tasks that have been studied from this point of view include game playing, language translation, natural-language understanding, robotics and the like. Challenging games such as chess have been the subject of intensive study, with the result that the leading modern chess programs can defeat almost all best human players.
Early attempts to translate from one language to another, even when the languages were somewhat similar (such as English and German) were based solely on dictionary lookup of words and mechanical syntax conversion. Results were often absurd. Recently AI researchers have achieved greater success by incorporating in the translation process knowledge about meaning and language use. Essentially, the approach is to understand a text before translating it. Thus natural language processing (understanding) becomes the key to translation, as well as being important in itself for
such applications as human-computer interaction through speech input.
