Reuse: Revisiting Sisyphus-VT

Reuse has long been a major goal of the Knowledge Engineering community. The focus of this paper is the reuse of domain knowledge acquired for an initial problem solver, with a further problem solver. For our analysis we chose a knowledge base system written in CLIPS based on the propose-andrevise (PnR) problem solver, and which had a lift/elevator knowledge base (KB). Given the nature of the p...

Editorial: the Sisyphus-VT initiative

This special issue contains results of the second ‘‘Sisyphus’’ study carried out in the knowledge acquisition community in the period 1992 – 1995 . The Sisyphus initiative arose at the 1990 European Knowledge Acquisition Workshop in Driebergen (The Netherlands) . To explain the rationale behind this initiative it is necessary to give a brief synopsis of the recent history of the knowledge-engin...

Parameterized VT area function inversion

The purpose of our study is to contribute tools for inversion of articulatory to acoustics relations, in specific to perform an estimate of vocal tract area-function parameters from formant frequencies. The inversion is performed in two steps. A first approximation is attained from either a codebook or a neural net and a final optimization is performed by an iterative interpolation for finding ...

Sisyphus-VT: A CommonKADS solution

This article contains a CommonKADS description of the Sisyphus ’93 problem : the VT elevator design . The term ‘‘CommonKADS’’ is used to refer to KADS as it has been developed within ESPRIT project P5248 KADS-II . The goal of this project was to arrive at a de facto European standard for KBS development . As the term ‘‘KADS’’ has become strongly associated with the University of Amsterdam , it ...
