Case-Based Reasoning Tool
案例式推理 (Case-Based Reasoning, CBR) 是知识表达的一种新方法， 最主要就是利用先前的经验来解决问题。 在 CBR 中， 知识是以过去的案例来表示。 而需要解决类似问题时， 便使用这些经验来引导推理。
简单地说, Case-Based Reasoning 就是：
人类推理的过程
推理过程的表达
在应用程序发展上，解决问题的一种方法论
如果您总是搞不清楚前向推理(forward chaining)，后向推理(backward chaining)， goal-directed reasoning， certainty factors 这些名词。而您的领域知识又很难用 if-then 的规则方式表达， 但却有大量的案例足以取样，则用 CBR的方式来解决问题，应是不错的选择。
CBR-Works
"Just think of everything you'd want a CBR
tool to do and CBR-Works does it!"
Dr. Ian Watson, Director AI-CBR
Most companies collect and file their data in databases or in huge filing cabinets.
Yet they do not use this valuable source of information to its full potential and improve
their services. CBR-Works opens this source of knowledge about your products and
projects and makes it available to your employees, customers, and suppliers - online,
on CD-ROM, or on the Intranet.
A person, who knows what to search for will find it.
A person, who does not know will become lost!
CBR-Works stands for a whole product line of development tools for the acquisition, processing, and distribution of information. CBR-Works lets your customers get help from Virtual Assistants.
CBR-Works actively supporting users as they search databases, letting your existing databases become intelligent support systems and knowledge bases. Information garnered through the search process is modeled and maintained in a knowledge model.
With easily formulated queries, CBR-Works delivers precise and meaningful answers. As an experienced expert, your system knows background information and relationships. Even when these relationships are not expressed during a query, they are used during searches and are reflected in the quality of the answers.
You can observe the intelligent behavior of such systems by looking at the alternatives suggested from searches. With conventional database systems, how good the search results are greatly depends on the user's knowledge of the system. CBR-Works quickly and reliably finds the best solution for a problem, even for the nonexpert.
