Abstract: This paper describes an attempt to integrate an expert system with a hypertext database of relevant primary and secondary text materials. The domain of law represented is that of the Brussels Convention 1968. Three dimensions of system development are addressed. With regard to the legal dimension, the choice of domain and the representation of both knowledge and data are considered. O...

Chicken or Checkin’? Rational Learning in Repeated Chess Games We examine rational learning among expert chess players and how they update their beliefs in repeated games with the same opponent. We present a model that explains how equilibrium play is affected when players change their choice of strategy when receiving additional information from each encounter. We employ a large international ...

We investigate “intelligent” grasping schemes using a fuzzy logic rule base expert system. In this paper, we use a vision system, robot arm and mechanical hand to locate and manipulate unmodeled, randomly placed objects of various sizes and shapes. In the pregrasp stage, we use vision data to provide a nonlinear mapping from object characteristics to hand configuration. In the postgrasp stage, ...

Job-specific modules (JSMs) were used to collect information for expert retrospective exposure assessment in a community-based non-Hodgkins Lymphoma study in New South Wales, Australia. Using exposure assessment by a hygienist, artificial neural networks were developed to predict overall and intermittent benzene exposure among the module of tanker drivers. Even with a small data set (189 driver...

A knowledge-based interactive system for choosing abstract data structures and concrete represent.* tions for them is described. The system acts as an "expert" on data structures and is to be consulted by programmers during the design stage of their work A specification method is described which assumes a restricted vocabulary of data structure terminology common to the user and the system. The...

This paper has as main goal to develop a hybrid expert system to minimize some of the complexity problems related to arti cial intelligence eld. For instance, we can mention: the so-called bottleneck of expert systems, e.g., the knowledge elicitation process; the choice of the model for the knowledge representation to code human reasoning; In relation to the connectionist approach, the number o...

This paper describes the prototype version of Sales Contractor, a computer system which produces standard or variable contracts for the sale of goods. Although built using an expert system shell, Sales Contractor operates as a decision support system, advising the user about which clauses to include in the contract, but leaving the final choice to him/her. Sales Contractor represents the first ...

test method facet is one of the factors which can have an influence on the test takers’ performance. the purpose of the current study was to investigate the effects of two different response types, multiple-choice cloze and multiple-choice test, on the pre-intermediate and intermediate test takers’ reading comprehension performance. to this end, 40 pre-intermediate and intermediate learners par...

Worst-case bounds on the expected shortfall risk given only limited information on the distribution of the random variables has been studied extensively in the literature. In this paper, we develop a new worst-case bound on the expected shortfall when the univariate marginals are known exactly and additional expert information is available in terms of bivariate marginals. Such expert informatio...
