At the University of Kansas, we are collecting cases and advice and making it available by computer. The software, Fabrication error Indexed eXamples and Solutions (FIXS), is a knowledge-based system to provide quick, possible solutions to fabrication errors suitable for use by multiple DOTs. The sharable database can lead to standardized solution procedures that would expedite bridge fabricati...

We introduce the “baby designer enterprise” with the objective of learning grounded symbols and rules based on experience, in order to construct the knowledge underlying design systems. In this approach, conceptual categories emerge as abstractions on patterns arising from functional constraints. Eventually, through interaction with language users, these concepts get names, and become true symb...

Many researchers believe that tacitness of knowledge contributes to incomplete knowledge flow. In this article, the authors focus on obtaining the required mechanical and electrical tacit knowledge for architectural conceptual design purpose by observing activities of a design team involved in a green building project. The authors used the case study research methodology to demonstrate how the ...

In this paper we present the following view on problem-solving methods for knowledge-based systems: Problem-solving methods describe an efficient reasoning strategy for achieving a goal by introducing assumptions about the available domain knowledge and the required functionality. Assumptions, dynamic reasoning behavior, and functionality are the three elements necessary to characterize a probl...

This paper describes the QUality and Experience Metric (QUEM), a method for estimating the skill level of a knowledgebased system based on the quality of the solutions it produces. It allows one to assess how many years of experience the system would be judged to have if it were a human by providing a quantitative measure of the system’s overall competence. QUEM can be viewed as a type of achie...

Constraints are used to manage the integrity of knowledge. Knowledge-based systems applications are frequently constructed as a knowledge base, or rule base, component coupled with a relational database component. The most expensive of these two components o build and maintain is typically the knowledge base. Constraints, which play a key role in database management, are seldom mentioned in con...

A knowledge system architecture is a level of description of knowledge systems that specialises general AI implementation techniques to suit a class of problem solving tasks. This paper presents three complementary views of the architecture level, and analyzes their implications for the design of knowledge en­ gineering tools. The analysis is illustrated with an architec­ ture for managing unce...

According to the current situation in emergency management of the low utilization and slow search for emergency document knowledge result to the efficiency in making decisions. This paper aims to solve the problem of difficult in searching needed knowledge in emergency management. From the perspective of knowledge system engineering, this paper conducts an in-depth study on knowledge-mined mode...

The Joseph Bell Centre for Forensic Statistics and Legal Reasoning has been set up to examine the correct presentation, interpretation and evaluation of scientific and forensic evidence through the use of technology. The aim of the Centre is to build computer systems for those operating in the legal system so that they can follow best practice whether investigating a crime or presenting evidenc...
