来自不同信息源的内涵知识的析取与利用：半自动方法与工具Extraction and Exploitation of Intensional Knowlesge from Heterogeneous Information Sources pdf 免费 地址 txt lrf 下载 kindle umd

This book is the first comprehensive approach to the c***truction and the management of cooperative information systems. From a set of input database schemes describing the information content of multiple sources, the techniques presented yield a structured, integrated and c***istent de*ion of the information content represented in a suitable data repository. The author builds his work on skilled and controlled use of results and methods from various fields of computer science, such as data mining, algorithmic learning, knowledge representation, database management, etc. The approach presented has been implemented in the prototype system DIKE, Database Intensional Knowledge Extractor, which has been studied in various application contexts.
