The Piracy "Industry" |
 |
Until recent years, the problem of piracy (the unauthorized reproduction or distribution of copyrighted works (for commercial purposes)) was largely confined to the copying and physical distribution of tapes, disks and CDs. Yet the emergence and increased use of global data networks and the WWW has added a new dimension to the piracy of  intellectual property by permitting still easier copying, electronic sales and transmissions of illegally reproduced copyrighted works on a grand scale.
This new development, often referred to as Internet piracy, broadly relates to the use of global data networks to 1) transmit and download digitized copies of pirated works, 2) advertise and market pirated intellectual property that is delivered on physical media through the mails or other traditional means, and 3) offer and transmit codes or other technologies which can be used to circumvent copy-protection security measures.
Lately the International Intellectual Property Alliance has published a new report on the estimated trade losses due to piracy. (The IIPA assumes that their report actually underestimates the loss of income due to the unlawful copying and distribution of copyrighted works. Yet it should be taken into consideration that the IIPA is the representative of the U.S. core copyright industries (business software, films, videos, music, sound recordings, books and journals, and interactive entertainment software).)

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.
