  Info and facts on 'Case-based reasoning'   (Site not responding. Last check: 2007-11-06)
Or, more radically, that all reasoning is based on past cases experienced or accepted by the being actively exercising choice -- prototype theory -- most deeply explored in human cognitive science (The field of science concerned with cognition; includes parts of cognitive psychology and linguistics and computer science and cognitive neuroscience and philosophy of mind).
CBR therefore tends to be a good approach for rich, complex domains in which there are myriad ways to generalize a case.
CBR traces its roots to the work of Roger Schank (additional info and facts about Roger Schank) and his students at Yale University in the early 1980s.

 Encyclopedia: Case based reasoning
Cases (precedents) are here not used to produce a single answer, but to interpret a situation in court, and to produce and assess arguments for both parties.
Cases may be indexed by a prefixed or open vocabulary, and within a flat or hierarchical index structure.
The case may still be learned, and be available in the case base in the intermediate period, but it has to be marked as a non-evaluated case.

 Case-based Reasoning
This type of reasoning is based on the premise that human beings learn and solve complex problems by using analogical or experiential reasoning.
Case-based knowledge is evident in precedence based reasoning (such as in tax law or accounting) and is useful when little evidence is available or the information is incomplete.
If no reasonably appropriate prior case is found, then the current case and its human created solution can be added to the case base thus allowing the system to learn.

CBR methods may be purely self-contained and automatic, or they may interact heavily with the user for support and guidance of its choices.
Finding a case in the case base that matches an input description is done by combining the input features of a problem case into a pointer to the case or category that shares most of the features.
Cases that match all input features are, of course, good candidates for matching, but - depending on the strategy - cases that match a given fraction of the problem features (input or inferred) may also be retrieved.

 [No title]
Historically and philosophically, CBR exists as a reaction to rule-based reasoning: In CBR, the emphasis is on the case, not the rule.
CBR seeks to determine a "source case" relevant to a given "target case." All CBR systems separate their reasoning into two stages: (1) finding the appropriate source case (retrieving); and (2) determining the appropriate conclusions in the target case (revising/reusing).
He refers to cases as "memories," retrieval of cases as "remindings," and representation of cases as "memory organization." Systems that owe their origin to this school of thought are considerable in scope and ability.

 Case-Based Reasoning   (Site not responding. Last check: 2007-11-06)
Case-based reasoning builds on the idea that human expertise is not composed of formal structures like rules, but of experience: a human expert reasons by relating a new problem to previous ones.Case-based reasoning now amounts to reasoning by comparing a new problem with a set of stored previous problems with their solution.
A major problem in case-based reasoning however, resides in the retrieval of cases that are sufficiently similar to a new problem at hand.
Based on the specific measure employed, the system associates a numerical value with each case indicating the similarity between this case and the problem under consideration.

 Case based reasoning   (Site not responding. Last check: 2007-11-06)
Case-based reasoning (CBR) is an intelligent-systems method that enables information managers to increase efficiency and reduce cost by substantially automating processes such as diagnosis, scheduling and design.
A case-based reasoner works by matching new problems to "cases" from a historical database and then adapting successful solutions from the past to current situations.
A collection of cases is called a case base and makes it possible to support for instance decision support for a specific part of a domain.

 Case-Based Reasoning: A Review (published in The Knowledge Engineering Review, Vol.9 No.4, 1994)   (Site not responding. Last check: 2007-11-06)
Case storage is an important aspect in designing efficient CBR systems in that, it should reflect the conceptual view of what is represented in the case and take into account the indices that characterise the case.
The goal of CBR systems is thus to be reminded of similar cases when faced with a new problem and to retrieve those cases in order to help the user solve the new problem in a fashion similar to the way it was solved for a closely matching situation.

 Case-Based Reasoning
Case-based Reasoning (CBR) is based on the intuition that new problems are often similar to previously encountered problems and, therefore, that past solutions may be of use in the current situation."
Instead of implying that legal reasoning is primarily a process of deduction or a process of analogising the theory of law as discourse requires a richer view of the process of legal reasoning."

 Case-Based Reasoning
Case-based reasoning (CBR) is the enterprise of solving new problems by analogy with old ones.
Problems and their solutions are stored as cases, and to solve a new problem, a CBR system retrieves a case of a similar problem, and adapts its solution to solve the new problem.
Cases can suggest solutions even to ill-defined problems in weak-theory domains for which there may be no adequate set of rules or hard-wired algorithms.

 Case based reasoning - Computing Reference - eLook.org
There are many situations where experts are not happy to be questioned about their knowledge by people who want to write the knowledge in rules, for use in expert systems.
In most of these situations, the natural way for an expert to describe his or her knowledge is through examples, stories or cases (which are all basically the same thing).
Some key research areas are efficient indexing, how to define "similarity" between cases and how to use temporal information.

 Case-Based Reasoning
We are, in essence, creating theories about the minute details in the world around us, trying to create a theory of dry cleaners that will help us to select the right one, or a theory of state government, or the behavior of our friends that will allow us to better function in the world.
We are constantly accumulating cases and comparing those cases to the cases we have already accumulated in a effort to understand the next case that will appear.

Over the last eight years, we have been working on the problem of case-based reasoning (CBR) for medical diagnosis.
Through a succession of research projects, we developed a system that used physiologic causes to match findings in cases, evaluated the system on 240 cases, and developed a system that divides cases and memory based on the diagnostic units in the case.
Still, it is clear that CBR has not reached its potential to effectively handle the case material and work in concert with a model-based program.
