摘 要: 针对当前企业诚信度评价精度低的难题,结合企业诚信度的特点,提出基于数据挖掘的企业诚信度评价模型。建立企业诚信度评价指标,并根据指标收集评价数据,采用主成分分析法对企业诚信度评价指标进行筛选,得到比较重要的企业诚信度评价指标,采用熵值法确定企业诚信度评价指标权值,并通过数据挖掘实现企业诚信度评价,进行具体企业诚信度评价测试。实验结果表明,所提方法能够有效挖掘企业诚信度的变化特点,获得了较高精度的企业诚信度评价结果。

Abstract: In order to improve the evaluation precision of the current enterprise credibility, the characteristics of enterprise credibility is combined to put forward a data mining based evaluation model of enterprise credibility. The evaluation index of enterprise credibility is established, according to which the evaluation data is collected. The principal component analysis is used to screen the evaluation index of enterprise credibility to obtain the more important evaluation index of the enterprise credibility. The entropy method is adopted to determine the weight of the enterprise credibility evaluation index. The data mining is used to realize the evaluation of enterprise credibility. The specific evaluation of enterprise credibility was tested. The experimental results show that the method can mine the change characteristics of enterprise credibility effectively, and obtain the high?precision evaluation result of enterprise credibility.
Keywords: enterprise credibility; evaluation model; data mining; simulation experiment; evaluation index; entropy method

随着企业规模的发展以及经济全球化的发展,企业之间的竞争越来越激烈,企业诚信度是衡量一个企业优劣的重要指标,因此对企业诚信度进行准确评价,具有十分重要的研究意义[1]。
针对企业诚信度评价问题,国内外专家和学者进行不懈的研究,而且花费了大量的时间和精力,提出了许多有效的企业诚信度评价方法[2]。最原始的企业诚信度评价方法主要通过一些专家和学者组成评价团,通过对比和分析对具体一个企业诚信度进行评价,它们评价结果比较直观,由于各专家和学者看问题角度、审美的角度不一样,导致评价结果差别较大,使得企业诚信度评价结果具有一定的主观盲目性[3?5]。近年来,随着计算机技术和信息处理……
