【摘要】：信息质量已经成为诸多应用领域所面临的一个重要问题,自动检测和修复信息系统中的信息错误是改善信息质量的有效手段.利用Web对关系数据库中的信息进行扩展以助于信息错误的自动检测与修复具有对待检测与修复的信息本身依赖少、信息质量规则更灵活、适用性更广以及信息修复相对更准确等优势,可以有效克服现有的基于规则、基于扩展信息和基于人机交互的信息错误检测与修复技术的不足.文中详细分析了基于Web信息的信息错误自动检测与修复技术的优势及所面临的挑战,提出了基于Web信息的信息错误自动检测与修复技术框架.该框架包括:Web信息自动拓展模型、基于Web信息的信息错误自动检测算法、基于Web信息的信息错误自动修复算法和基于Web信息的信息错误自动检测与修复算法的可靠性评估模型.基于上述框架,文中系统总结了基于Web信息的信息错误自动检测技术、信息错误自动修复技术以及信息扩展核心技术三个方面的研究进展,提炼出了基于Web信息的信息错误自动检测与修复技术需要解决的关键科学问题,对未来的研究方向进行了展望并且讨论了初步的研究思路.
[Abstract]:The quality of information has become an important problem in many application fields. Automatic detection and repair of information errors in information systems is an effective means to improve the quality of information. The use of Web to expand the information in relational databases to help the automatic detection and repair of information errors with the treatment of detection and repair. Complex information itself is less dependent, The advantages of more flexible information quality rules, wider applicability and more accurate information repair can effectively overcome the existing rule-based rules. Based on extended information and human-computer interaction based information error detection and repair technology shortcomings. This paper analyzes the advantages and challenges of automatic information error detection and repair technology based on Web information. In this paper, a technical framework of automatic error detection and repair based on Web information is proposed. The framework includes the automatic extension model of Web information, the algorithm of automatic error detection based on Web information, and the algorithm of automatic error detection based on Web information. The reliability evaluation model of information error auto-repair algorithm based on Web information and information error detection and repair algorithm based on Web information is presented. Based on the above framework, the information error automatic detection technology based on Web information is systematically summarized in this paper. The research progress of information error automatic repair technology and information extension core technology is summarized. The key scientific problems that need to be solved in automatic information error detection and repair technology based on Web information are extracted. The future research direction is prospected and the preliminary research ideas are discussed.
