Case-Based Reasoning Tool

案例式推理 (Case-Based Reasoning, CBR) 是知識表達(dá)的一種新方法， 最主要就是利用先前的經(jīng)驗(yàn)來解決問題。 在 CBR 中， 知識是以過去的案例來表示。 而需要解決類似問題時， 便使用這些經(jīng)驗(yàn)來引導(dǎo)推理。
簡單地說, Case-Based Reasoning 就是：

人類推理的過程
推理過程的表達(dá)
在應(yīng)用程序發(fā)展上，解決問題的一種方法論
如果您總是搞不清楚前向推理(forward chaining)，后向推理(backward chaining)， goal-directed reasoning， certainty factors 這些名詞。而您的領(lǐng)域知識又很難用 if-then 的規(guī)則方式表達(dá)， 但卻有大量的案例足以取樣，則用 CBR的方式來解決問題，應(yīng)是不錯的選擇。

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.
