Shyster (expert System)
SHYSTER is a legal expert system developed at the Australian National University in Canberra in 1993. It was written as the doctoral dissertation of James Popple under the supervision of Robin Stanton, Roger Clarke, Peter Drahos, and Malcolm Newey. A full technical report of the expert system, and a book . Also . further detailing its development and testing have also been published. SHYSTER emphasises its pragmatic approach, and posits that a legal expert system need not be based upon a complex model of legal reasoning in order to produce useful advice. Although SHYSTER attempts to model the way in which lawyers argue with cases, it does not attempt to model the way in which lawyers decide which cases to use in those arguments. SHYSTER is of a general design, permitting its operation in different legal domains. It was designed to provide advice in areas of case law that have been specified by a legal expert using a bespoke specification language. Its knowledge of the law i ...

Private Law
Private law is that part of a civil law legal system which is part of the '' jus commune'' that involves relationships between individuals, such as the law of contracts and torts (as it is called in the common law), and the law of obligations (as it is called in civil legal systems). It is to be distinguished from public law, which deals with relationships between both natural and artificial persons (i.e., organizations) and the state, including regulatory statutes, penal law and other law that affects the public order. In general terms, private law involves interactions between private individuals, whereas public law involves interrelations between the state and the general population. Concept One of the five capital lawyers in Roman law, Domitius Ulpianus, (170–223) – who differentiated ius publicum versus ius privatum – the European, more exactly the continental law, philosophers and thinkers want(ed) to put each branch of law into this dichotomy: Public and Pri ...

Compact Cassette
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips in 1963, Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed - for example the Microcassette - the generic term ''cassette tape'' is normally always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally designed for dictation machines, but improvements in fidelity led to it supplanting the stereo 8-track cartridge an ...

Australian Copyright Act 1968
The copyright law of Australia defines the legally enforceable rights of creators of creative and artistic works under Australian law. The scope of copyright in Australia is defined in the ''Copyright Act 1968'' (as amended), which applies the national law throughout Australia. Designs may be covered by the ''Copyright Act'' (as sculptures or drawings) as well as by the ''Registered Designs, Design Act''. Since 2007, Performing arts, performers have moral rights in recordings of their work. Until 2004, copyright in Australia was based on the "plus 50" law which restricts works until 50 years after the author's death. In 2004 this was changed to a "plus 70" law in line with the USA and European Union, but this change was not made retroactive (unlike the 1995 change in the European Union which brought some, e.g. British authors, back into copyright). The consequence is that the work of an Australian author who died before 1955 is normally in the public domain in Australia. However ...

Digital Rights Management
Digital rights management (DRM) is the management of legal access to digital content. Various tools or technological protection measures (TPM) such as access control technologies can restrict the use of proprietary hardware and copyrighted works. DRM technologies govern the use, modification, and distribution of copyrighted works (such as software and multimedia content), as well as systems that enforce these policies within devices. Laws in many countries criminalize the circumvention of DRM, communication about such circumvention, and the creation and distribution of tools used for such circumvention. Such laws are part of the United States' Digital Millennium Copyright Act (DMCA), and the European Union's Information Society Directive (the French DADVSI is an example of a member state of the European Union implementing the directive). DRM techniques include licensing agreements and encryption. The industry has expanded the usage of DRM to various hardware products, such ...

Natural Justice
In English law, natural justice is technical terminology for the rule against bias (''nemo iudex in causa sua'') and the right to a fair hearing ('' audi alteram partem''). While the term ''natural justice'' is often retained as a general concept, it has largely been replaced and extended by the general "duty to act fairly". The basis for the rule against bias is the need to maintain public confidence in the legal system. Bias can take the form of actual bias, imputed bias, or apparent bias. Actual bias is very difficult to prove in practice whereas imputed bias, once shown, will result in a decision being void without the need for any investigation into the likelihood or suspicion of bias. Cases from different jurisdictions currently apply two tests for apparent bias: the "reasonable suspicion of bias" test and the "real likelihood of bias" test. One view that has been taken is that the differences between these two tests are largely semantic and that they operate similarly ...

Trover
Trover () is a form of lawsuit in common-law countries for recovery of damages for wrongful taking of personal property. Trover belongs to a series of remedies for such wrongful taking, its distinctive feature being recovery only for the value of whatever was taken, not for the recovery of the property itself (see replevin). Overview Although actions in trover can be traced to the time of Bracton, and later Edward I of England, it became more clearly defined later during the reign of Henry VI of England, 1422–1461 and 1470–1471. Action in trover became a mature legal doctrine during the reign of Elizabeth I of England, 1558–1603. Early trover cases involved the keeping or taking of a bailment by the bailee (the person charged to hold the property with "ordinary care"). Others concerned the use of lost chattels found by another and determining who was the real owner. Early on, there was difficulty in dealing with situations where chattels held by a bailee were used by ...

Pattern Recognition
Pattern recognition is the automated recognition of patterns and regularities in data. It has applications in statistical data analysis, signal processing, image analysis, information retrieval, bioinformatics, data compression, computer graphics and machine learning. Pattern recognition has its origins in statistics and engineering; some modern approaches to pattern recognition include the use of machine learning, due to the increased availability of big data and a new abundance of processing power. These activities can be viewed as two facets of the same field of application, and they have undergone substantial development over the past few decades. Pattern recognition systems are commonly trained from labeled "training" data. When no labeled data are available, other algorithms can be used to discover previously unknown patterns. KDD and data mining have a larger focus on unsupervised methods and stronger connection to business use. Pattern recognition focuses more on the si ...

Nearest Neighbor Search
Nearest neighbor search (NNS), as a form of proximity search, is the optimization problem of finding the point in a given set that is closest (or most similar) to a given point. Closeness is typically expressed in terms of a dissimilarity function: the less similar the objects, the larger the function values. Formally, the nearest-neighbor (NN) search problem is defined as follows: given a set ''S'' of points in a space ''M'' and a query point ''q'' ∈ ''M'', find the closest point in ''S'' to ''q''. Donald Knuth in vol. 3 of ''The Art of Computer Programming'' (1973) called it the post-office problem, referring to an application of assigning to a residence the nearest post office. A direct generalization of this problem is a ''k''-NN search, where we need to find the ''k'' closest points. Most commonly ''M'' is a metric space and dissimilarity is expressed as a distance metric, which is symmetric and satisfies the triangle inequality. Even more common, ''M'' is take ...

Knowledge Representation
Knowledge representation and reasoning (KRR, KR&R, KR²) is the field of artificial intelligence (AI) dedicated to representing information about the world in a form that a computer system can use to solve complex tasks such as diagnosing a medical condition or having a dialog in a natural language. Knowledge representation incorporates findings from psychology about how humans solve problems and represent knowledge in order to design formalisms that will make complex systems easier to design and build. Knowledge representation and reasoning also incorporates findings from logic to automate various kinds of ''reasoning'', such as the application of rules or the relations of sets and subsets. Examples of knowledge representation formalisms include semantic nets, systems architecture, frames, rules, and ontologies. Examples of automated reasoning engines include inference engines, theorem provers, and classifiers. History The earliest work in computerized knowledge rep ...

Jurisprudence
Jurisprudence, or legal theory, is the theoretical study of the propriety of law. Scholars of jurisprudence seek to explain the nature of law in its most general form and they also seek to achieve a deeper understanding of legal reasoning and analogy, legal systems, legal institutions, and the proper application of law, the economic analysis of law and the role of law in society. Modern jurisprudence began in the 18th century and it was based on the first principles of natural law, civil law, and the law of nations. General jurisprudence can be divided into categories both by the type of question scholars seek to answer and by the theories of jurisprudence, or schools of thought, regarding how those questions are best answered. Contemporary philosophy of law, which deals with general jurisprudence, addresses problems internal to law and legal systems and problems of law as a social institution that relates to the larger political and social context in which it exists.Sh ...
