SHYSTER: A Pragmatic Legal Expert System by James Popple Pdf

Most legal expert systems attempt to implement complex models of legal reasoning. But the utility of a legal expert system lies not in the extent to which it simulates a lawyer’s approach to a legal problem, but in the quality of its predictions and of its arguments. A complex model of legal reasoning is not necessary: a successful legal expert system can be based upon a simplified model of legal reasoning. Some researchers have based their systems upon a jurisprudential approach to the law, yet lawyers are patently able to operate without any jurisprudential insight. A useful legal expert system should be capable of producing advice similar to that which one might get from a lawyer, so it should operate at the same pragmatic level of abstraction as does a lawyer—not at the more philosophical level of jurisprudence. A legal expert system called SHYSTER has been developed to demonstrate that a useful legal expert system can be based upon a pragmatic approach to the law. SHYSTER has a simple representation structure which simplifies the problem of knowledge acquisition. Yet this structure is complex enough for SHYSTER to produce useful advice. SHYSTER is a case-based legal expert system (although it has been designed so that it can be linked with a rule-based system to form a hybrid legal expert system). Its advice is based upon an examination of, and an argument about, the similarities and differences between cases. SHYSTER attempts to model the way in which lawyers argue with cases, but it does not attempt to model the way in which lawyers decide which cases to use in those arguments. Instead, it employs statistical techniques to quantify the similarity between cases. It decides which cases to use in argument, and what prediction it will make, on the basis of that similarity measure. SHYSTER is of a general design: it can provide advice in areas of case law that have been specified by a legal expert using a specification language. Hence, it can operate in different legal domains. Four different, and disparate, areas of law have been specified for SHYSTER, and its operation has been tested in each of those domains. Testing of SHYSTER in these four domains indicates that it is exceptionally good at predicting results, and fairly good at choosing cases with which to construct its arguments. SHYSTER demonstrates the viability of a pragmatic approach to legal expert system design.

A Hybrid Intelligent System Approach to Legal Reasoning by Pooja Raundale Pdf

Many legal expert systems are dependent on the concept of complex models. They are implemented using these complex models of legal reasoning. The legal expert systems are useful only if they are used by the users. The users of the expert systems are mainly common men, lawyers or any other person who is studying law. The usability of the Expert System predominantly depends on the quality factor of the system. A complex model of legal reasoning is not necessary; a successful legal expert system can be based upon a simplified model of legal reasoning. A useful legal expert system should be capable of producing advice similar to a lawyer, so it should operate at the same way as a lawyer works in his area. A legal expert system called NIRNAY has been developed to demonstrate that a useful legal expert system can be based upon a pragmatic approach to the law. NIRNAY is a Hybrid Intelligent System which uses two methods of reasoning to give the advice to the user of the system. NIRNAY has an Application layer above the two modules. These modules are Case Based Reasoner module and Rule Based Reasoner module. The rule base and case base are used for representation of knowledge about the domain. NIRNAY is a hybrid intelligent system in the sense that its advice is based upon the two methods of reasoning; it uses the Rule Based Reasoning and Case Based Reasoning to produce the advice. The first module i.e. RBR module checks the validity of the contract and the argument is produced by the CBR module for Breach of Building Contract, an argument, about the similarities and differences between cases. NIRNAY tries to use the way in which lawyers argue with cases. It also attempts to use the way in which lawyers decide which cases to use in the arguments. It makes use of 'similarity measure' to find the similarity between the cases. It decides which cases to use in argument, and what prediction it will make, on the basis of that similarity measure. NIRNAY is tested for both the modules and it indicates that it is exceptionally good at predicting results, and fairly good at choosing cases with which to construct its arguments. NIRNAY demonstrates the viability of a pragmatic approach to legal expert system design.

A Pragmatic Legal Expert System by James Popple Pdf

Most legal expert systems attempt to implement complex models of legal reasoning. This book argues that a complex model is unnecessary. It advocates a simpler, pragmatic approach in which the utility of a legal expert system is evaluated by reference, not to the extent to which it simulates a lawyer's approach to a legal problem, but to the quality of its predictions and of its arguments. The author describes the development of a legal expert system, called SHYSTER, which takes a pragmatic approach to case law. He discusses the testing of SHYSTER in four different and disparate areas of case law, and draws conclusions about the advantages and limitations of this approach to legal expert system development. Chapter 1 presents a critical analysis of previous work of relevance to the development of legal expert systems. Chapter 2 explains the pragmatic approach that was adopted in the development of SHYSTER. The implementation of SHYSTER is detailed using examples in chapter 3. Chapter 4 describes the testing of SHYSTER, and conclusions are drawn from those tests in chapter 5. Examples of SHYSTER's output are provided in appendices.

Expert Systems in Law by Richard E. Susskind Pdf

Expert systems are computer systems that engage in legal reasoning by assisting general legal practitioners in solving legal problems beyond their range of knowledge or expertise. This book is a comprehensive investigation of expert systems in law. Susskind uses jurisprudence throughout the book to articulate the presuppositions and limitations of building such systems, and to provide sound practical guidance for their design.

Law on Display by Neal Feigenson,Christina Spiesel Pdf

Visual and multimedia digital technologies are transforming the practice of law: how lawyers construct and argue their cases, present evidence to juries, and communicate with each other. They are also changing how law is disseminated throughout and used by the general public. What are these technologies, how are they used and perceived in the courtroom and in wider culture, and how do they affect legal decision making? In this comprehensive survey and analysis of how new visual technologies are transforming both the practice and culture of American law, Neal Feigenson and Christina Spiesel explain how, when, and why legal practice moved from a largely words-only environment to one more dependent on and driven by images, and how rapidly developing technologies have further accelerated this change. They discuss older visual technologies, such as videotape evidence, and then current and future uses of visual and multimedia digital technologies, including trial presentation software and interactive multimedia. They also describe how law itself is going online, in the form of virtual courts, cyberjuries, and more, and explore the implications of law’s movement to computer screens. Throughout Law on Display, the authors illustrate their analysis with examples from a wide range of actual trials.
