Expert systems are sophisticated computer applications that contain representations of human expertise. They can apply this knowledge to solve problems and offer advice much as a human expert does, through interactive dialogue with non-experts. The systems offer explanations of the lines of reasoning they explore and of the conclusions they reach. The authors of this book have developed the first such expert system, called the Latent Damage System, to be built in the United Kingdom for lawyers and other advisors in professional practice. The book should be used in conjunction with the complimentary computer discs. The text begins with an introduction of expert systems in law and latent damage law. The early investigative stages of the Latent Damage System and its development as a computer system are outlined. The final chapter of the book highlights the power and limitations of the system, itemizes the skills required for a major project in this field, considers legal liability for expert systems and discusses the impact of expert systems in law on legal publishing. A combined book and disc edition is also available as well as a separate disc pack.
