The Copyright Industry Copyright is not only about protecting the rights of creators, but has also become a major branch of industry with significant contributions to the global economy. According to the International Intellectual Property Alliance the U.S. copyright industry has grown almost three times as fast as the economy as a whole for the past 20 years. In 1997, the total copyright industries contributed an estimated US$ 529.3 billion to the U.S. economy with the core copyright industries accounting for US$ 348.4 billion. Between 1977 and 1997, the absolute growth rate of value added to the U.S. GDP by the core copyright industries was 241 %. Also the copyright industry's foreign sales in 1997 (US$ 66.85 billion for the core copyright industries) were larger than the U.S. Commerce Department International Trade Administration's estimates of the exports of almost all other leading industry sectors. They exceeded even the combined automobile and automobile parts industries, as well as the agricultural sector. In an age where knowledge and information become more and more important and with the advancement of new technologies, transmission systems and distribution channels a further increase in the production of intellectual property is expected. Therefore as copyright establishes ownership in intellectual property it is increasingly seen as the key to wealth in the future.

Expert system Expert systems are advanced computer programs that mimic the knowledge and reasoning capabilities of an expert in a particular discipline. Their creators strive to clone the expertise of one or several human specialists to develop a tool that can be used by the layman to solve difficult or ambiguous problems. Expert systems differ from conventional computer programs as they combine facts with rules that state relations between the facts to achieve a crude form of reasoning analogous to artificial intelligence. The three main elements of expert systems are: (1) an interface which allows interaction between the system and the user, (2) a database (also called the knowledge base) which consists of axioms and rules, and (3) the inference engine, a computer program that executes the inference-making process. The disadvantage of rule-based expert systems is that they cannot handle unanticipated events, as every condition that may be encountered must be described by a rule. They also remain limited to narrow problem domains such as troubleshooting malfunctioning equipment or medical image interpretation, but still have the advantage of being much lower in costs compared with paying an expert or a team of specialists.
