Prolog is a programming language, but a rather unusual one. ``Prolog'' is shortfor ``Programming with Logic'', and the link with logic gives Prolog itsspecial character. At the heart of Prolog lies a surprising idea: don't tellthe computer what to do. Instead, describe situations of interest, and computeby asking questions. Prolog will logically deduce new facts about thesituations and give its deductions back to us as answers.Why learn Prolog? For a start, its ``say what the problem is, rather than howto solve it'' stance, means that it is a very high level language, good forknowledge rich applications such as artificial intelligence, natural languageprocessing, and the semantic web. So by studying Prolog, you gain insight intohow sophisticated tasks can be handled computationally. Moreover, Prologrequires a different mindset. You have to learn to see problems from a newperspective, declaratively rather than procedurally.Acquiring this mindset, and learning to appreciate the links between logic andprogramming, makes the study of Prolog both challenging and rewarding.Learn Prolog Now! is a practical introduction to this fascinatinglanguage.
