The study aim was to compare expert with non-expert swimmers' rating of the aesthetic and technical qualities of front crawl in video-taped recordings of swimmers with low, middle, and high level proficiency. The results suggest that: i) observers' experience affects their judgment: only the expert observers correctly rated the swimmers' proficiency level; ii) evaluation of movement (technical ...

This study examined differences in self-regulation among college-age expert, moderately expert, and non-expert video game players in playing video games for fun. Winne's model of self-regulation (Winne, 2001) guided the study. The main assumption of this study was that expert video game players used more processes of self-regulation than the less-expert players. We surveyed 143 college students...

Tasks that require users to have expert knowledge are difficult to crowdsource. They are mostly too complex to be carried out by non-experts and the available experts in the crowd are difficult to target. Adapting an expert task into a non-expert user task, thereby enabling the ordinary “crowd” to accomplish it, can be a useful approach. We studied whether a simplified version of an expert anno...

\It seems to me, that work in databases, logic programming, deductive databases, artii-cial intelligence and expert systems will move closer towards one another. Formalisms and techniques developed in each one of those areas will assist the others. Science builds on theories." | J. Minker, 1987

1. Qyerview of the System. Current approaches to expert systems' reasoning under uncertainty fail to capture the iterative revision process characteris­ tic of intelligent human reasoning. This paper reports on a system, called the Non-monotonic Probabilist, or NMP (Cohen, et al., 1985). When its in­ ferences result in substantial conflict, NMP examines and revises the assump­ tions underlying ...

Lagrangian analysis is becoming increasingly important to better understand the ocean's biological and biogeochemical cycles. Yet, biologists chemists often lack technical skills required set up such analyses. Here, we present a new product of pre-computed ocean Lagrangian trajectories (OLTraj) targeting non-expert users, demonstrate how use it by means worked examples. OLTraj based on s...
