This paper propose an integrated intelligent approach to enhancing process diagnosis automation (IIPD). A parallel hierarchical architecture is developed for IIPD, where various subsystems are coordinated by a meta-system. As the kernel of IIPD, the meta-system is endowed with a better understanding of diagnostic problem-solving and aims at large scale knowledge integration. Subsystems include ...

The SIGNAL insurance companies have developed an expert system for the support of its customer sales service. It was introduced at the end of 1993 and is currently used by approximately 500 customer service representatives. It involves a counseling system, which enables customer sales personnel to produce high-quality benefit analyses at the point of sale. It is not only an information system f...

Introduction Expert system can be defined as a tool for information generation from knowledge. Information is either found in various forms or generated from data and/or knowledge. Text, images, video, audio are forms of media on which information can be found, and the role of information technology is to invent, and devise tools to store and retrieve this information. Statistical information i...

Equifax Check Services provides retail merchants and other businesses with quality decisions concerning the acceptability. risk. or fraudulence of customer checks. The greatest percentage of these decisions are provided automatically through on-line links with point-of-sale termmalls. When a transaction is suspect, a referraY notice is generated directing the merchant to call one of Equifax Che...

No matter which area of business one is engaged in, expert systems can be used to fulfill the need for higher productivity and reliability of decisions. Expert systems are most valuable to organizations that have a high-level of knowhow experience and expertise that cannot be easily transferred to other members. They are designed to carry the intelligence and information found in the intellect ...

This article deals with hybrid expert system that has knowledge base realized through a hierarchical structure of artificial neural networks (NN). The decision tree is built by C4.5 algorithm at first. In the next step the nods of the tree are replaced by NN. They are trained to split the data in the same way as the nods. So the problem is separated into partial sub-problems that are solved by ...

Service-Oriented Architecture (SOA) is one of the technologies under extensive discussion in recent years, and most noteworthy of all are Web Services. Web Services utilize core technologies, such as Extensible Markup Language (XML), Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL) and Universal Description, Discovery, and Integration (UDDI), to construct an easy c...

We briefly describe the medical expert system Cadiag-2, developed to support the differential diagnostic process in internal medicine. We propose a propositional logic called fuzzy probability logic as a possible formalization of Cadiag-2 and indicate the way of transferring Cadiag-2's methodology into this framework.

This paper presents an application of the Dempster-Shafer evidence combination scheme in building a rule based expert system shell for diagnostic reasoning. Domain knowledge is stored as rules with associated belief functions. The reasoning component uses a combination of forward and backward inferencing mechanisms to interact with the user in a mixed initiative format.
