从数据挖掘到知识发现 总被引:1,自引:0,他引:1
<正> KDD简介 过去的十年里,生成和收集数据的能力迅猛发展。科学数据集、商品的条形码、商业的计算机化和政府事务等都产生了海量的数据。 如此大量的数据明显超出了传统手工数据分析方法的分析能力。这些方法能够从数据中产生信息报告,但不能分析这些报告的内容以便集中处理。这就要求新一代技术与工具具备智能地并且自动地帮助人们分析海量数据来获取有用知识的能力。 从原始数据中发现有用的模式(或知识)通常称之为数据库中的知识发现,简称KDD。这种称法出现于 相似文献

The proliferation of large masses of data has created many new opportunities for those working in science, engineering and business. The field of data mining (DM) and knowledge discovery from databases (KDD) has emerged as a new discipline in engineering and computer science. In the modern sense of DM and KDD the focus tends to be on extracting information characterized as knowledge from data that can be very complex and in large quantities. Industrial engineering, with the diverse areas it comprises, presents unique opportunities for the application of DM and KDD, and for the development of new concepts and techniques in this field. Many industrial processes are now automated and computerized in order to ensure the quality of production and to minimize production costs. A computerized process records large masses of data during its functioning. This real-time data which is recorded to ensure the ability to trace production steps can also be used to optimize the process itself. A French truck manufacturer decided to exploit the data sets of measures recorded during the test of diesel engines manufactured on their production lines. The goal was to discover knowledge in the data of the test engine process in order to significantly reduce (by about 25%) the processing time. This paper presents the study of knowledge discovery utilizing the KDD method. All the steps of the method have been used and two additional steps have been needed. The study allowed us to develop two systems: the discovery application is implemented giving a real-time prediction model (with a real reduction of 28%) and the discovery support environment now allows those who are not experts in statistics to extract their own knowledge for other processes. 相似文献

TheNielsen Opportunity Explorer
tmproduct can be used by sales and trade marketing personnel within consumer packaged goods manufacturers to understand how their products are performing in the market place and find opportunities to sell more product, more profitably to the retailers. Opportunity Explorer uses data collected at the point-of-sale terminals, and by auditors of A. C. Nielsen. Opportunity Explorer uses a knowledge-base of market research expertise to analyze large databases and generate interactive reports using knowledge discovery templates, converting a large space of data into concise, inter-linkedinformation frames. Each information frame addresses specific business issues, and leads the user to seek related information by means of dynamically created hyperlinks. 相似文献
