The authors presumed that it was possible to replace certain criteria of the expert system aimed at evaluating actual quality of basketball players, proposed by Trninić et al., with the corresponding indicators of situation-related efficiency (official statistics of the game). Hence, the aim of this study is to verify the potential of establishing such a combined model of expert system that would consist of both the evaluation criteria and certain number of objectively measurable aspects of actual quality (player's partial performance or playing efficiency) and to determine its pragmatic validity. To achieve the aim the sample comprised of 60 basketball players that were competing in the Croatian First Division League in the 1998/99 season was tested. The sample and their quality of play was described by the two different types of data: 1) the 13 situation-related efficiency data (FIBA statistics of the game) utilized to objectively assess performance or playing effectiveness of players, collected at 132 games played by 12 teams, and 2) the evaluation data, subjectively assessing actual quality of players, i.e. their perceived overall performance, collected at the end of the season from the 10 basketball trainers. On the basis of relatively high correlations within the 7 pairs of mutually equivalent variables (from 0.63 to 0.84) and the extremely high correlation (0.97) obtained between the perceived overall performance (actual quality), subjectively assessed with respect to the 19 criteria of the original expert evaluation system, and the overall performance (actual quality) assessed by the combined model (where the 8 evaluation criteria had been replaced by the 7 corresponding indicators ofplaying efficiency), it is feasible to consider the combined model of expert system as an acceptable tool for more objective and economical assessment of actual quality of basketball players.
作者推测,用与情境相关的效率的相应指标(比赛官方统计数据)来取代Trninić等人提出的旨在评估篮球运动员实际水平的专家系统的某些标准是可行的。因此,本研究的目的是验证建立这样一个专家系统组合模型的潜力,该模型将由评估标准和实际水平的若干客观可衡量方面(球员的部分表现或比赛效率)组成,并确定其实际有效性。为实现这一目标,对1998/99赛季克罗地亚甲级联赛中的60名篮球运动员进行了测试。通过两种不同类型的数据描述样本及其比赛水平:1)13个与情境相关的效率数据(国际篮联比赛统计数据)用于客观评估球员的表现或比赛有效性,这些数据是在12支球队进行的132场比赛中收集的;2)评估数据,主观评估球员的实际水平,即他们在赛季结束时从10名篮球教练那里收集到的总体表现感知。基于7对相互等效变量之间相对较高的相关性(从0.63到0.84),以及在根据原始专家评估系统的19条标准主观评估的总体表现(实际水平)与组合模型评估的总体表现(实际水平)(其中8条评估标准已被7条相应的比赛效率指标取代)之间获得的极高相关性(0.97),可以认为专家系统组合模型是更客观、经济地评估篮球运动员实际水平的可接受工具。
