摘要:

AbstractIn response to the limitations of comtemporary database management systems in addressing the requirements of many potential application environments, and in view of the characteristics of emerging interconnected systems, we examine research directions involving adding more ‘intelligence’ to database systems. Three major thrusts in the intelligent database systems area are discussed. The first involves increasing the modeling power to represent an application environment. The second emphasis centers on enhancing the functionality of such a system to include rule‐based inference capabilities. The third direction focuses on supporting the interoperability of multiple, autonomous, heterogeneous database systems. We provide here a view of the first two thrusts, and examine the third via a description of the Remote‐Exchange research effort currently underway at USC.

摘要:

AbstractThe ‘SKADE LITotSET’ system is a blackboard‐based expert system that makes ‘litigate or settle’ decisions in the product liability area. It has three knowledge sources: Legal, Manager and Insurance Adjuster. The combined expertise from each of these is required to solve the ‘litigate or settle’ problem. The control component co‐ordinates the interaction between the various knowledge sources on the blackboard. Based on the latest changes to the data on the blackboard, it selects and executes the next knowledge source. The model reproduces the decision makers' opportunistic reasoning processes by the interaction between the various knowledge sources through the blackboard. The results of analyses of a hypothetical case through a series of experiments with the ‘SKADE LITorSET’ system indicate that the blackboard is an appropriate model for development of expert systems in the ‘litigate or settle’ decision domain. The initial success with the blackboard approach suggests that further work needs to be done to see whether more complex models can be built to incorporate a broader range of determinants of settlement decisions.

摘要:

AbstractExpert systems moved from research laboratories to widespread use in the business world during the previous decade. Current data indicate that use will continue to increase in the foreseeable future. However, auditors have not comprehensively addressed the need for and feasibility of independent audits of these systems. This paper discusses factors that will soon create a demand for independent audits of expert systems. It then identifies a framework present in current professional standards that appears to be appropriate for proceeding with the auditing of expert systems. A hypothetical case is subsequently presented to illustrate one possibility of how measurement criteria, audit procedures and an audit report developed under these professional standards might appear. Potential practice problems and research issues are identified throughout the paper.

摘要:

AbstractCOLOSSUS is a mainframe‐based expert system jointly developed by Continuum Australia and GIO (General Insurance Organization) for the assessment of third‐party claims. COLOSSUS has been in production for over two years and is accessible throughout all GIO regions in New South Wales, Australia. In this paper we describe the extension of COLOSSUS to cater for future economic loss to a claimant. Because of the diversity of knowledge sources in the insurance domain, we have adopted a highly interactive approach that requires successive user confirmations during a consultation. The practicality of our knowledge engineering approach is highlighted by examining several difficult issues. Design issues are also addressed with particular reference to clarity and ease of maintenance. An annotated report of a sample run is enclosed.

摘要:

AbstractESCFE (Expert System for Customer Facing Environments) is an integrated expert systems architecture which supports a three‐way dialogue between British Telecommunications (BT) customers, staff and its technical and commercial support systems. ESCFE is customer facing—this means that the user interface dialogue is directed explicitly at the customer, as opposed to other expert systems/help desks which have a user interface directed at staff, who then deal with the customer in whatever manner they have been trained. In dealing with the customer, BT staff require a wide range of knowledge concerning the products and services portfolio, internal BT procedures, selling opportunities, customer‐care policy and contractual liabilities. This knowledge can be contained within ESCFE. The knowledge is used to support a dialogue which allows for both customer‐ and staff‐driven interaction, and for different levels of expertise in both customers and staff.
