Ripple-Down Rationality: A Framework for Maintaining PSMs
نویسنده
چکیده
Knowledge-level (KL) modeling can be character-ised as theory subset extraction where the extracted subset is consistent and relevant to some problem. Theory subset extraction is a synonym for Newell's principle of rationality, Clancey's model construction operators, and Breuker's components of expert solutions. In an abductive framework, a PSM is the extraction controller and is represented by a suite of BEST inference assessment operators. Each BEST operator is a single-classiication expert system which accepts or culls a possible inference. PSMs can therefore be maintained by ripple-down-rules, a technique for maintaining single-classiication expert systems.

Simultaneous Modelling and Knowledge Acquisition Using NRDR
Incremental refinement methods of knowledge bases ease maintenance but fail to uncover the underlying domain model used by the expert. In this paper, we propose a new knowledge representation formalism for incremental acquisition and refinement of knowledge. It simultaneously guides the expert in expressing his model of the domain during the actual knowledge acquisition process. This knowledge ...
متن کاملMaintaining Procedural Knowledge: Ripple-down-functions
Research into the maintenance of procedural knowledge has focused on the detection of declarative meta-structures within the procedures. An alternative approach is described here based on the ripple-down-rules (RDR) formalism. To the standard RDR rule tree, we add a functions environment hierarchy that stores the implementation of the procedures used in the rules. This functions environment str...
متن کاملAcquisition of Search Knowledge
The development of highly eeective heuristics for search problems is a diicult and time-consuming task. We present a knowledge acquisition approach to incrementally model expert search processes. Though, experts do not normally have introspective access to that knowledge , their explanations of actual search considerations seems very valuable in constructing a knowledge level model of their sea...
متن کاملNRDR for the Acquisition of Search Knowledge
The contribution of this paper is threefold: It substantially extends Ripple Down Rules, a proven eeective method for building large knowledge bases without a knowledge engineer. Furthermore, we propose to develop highly eeective heuristics searchers for combinatorial problems by a knowledge acquisition approach to acquire human search knowledge. Finally, our initial experimental results sugges...
متن کاملVisualRDR: A general framework for creating, maintaining and learning of ripple down rules for Information Extraction
The problem facing the industry and the common user today is that of an information glut. Large amounts of useful information, in various forms, are being generated mostly for human consumption. This deluge of information requires us to find ways of gathering information from such unstructured sources with as little manual intervention as possible. This has been made possible by information ext...
