摘要
论述了国外基于非相关文献的知识发现系统中所使用的算法---四种关联挖掘算法即Association Rules、TF-IDF、Z-Score和MIM,三种目标词排序算法即AMW、LTC-AMW和COH,希望能对国内知识发现方法的研究提供参考,以指导国内研究者开发出适合中文文献数据库的知识发现系统,为医学及其他领域提供有用的知识发现工具。
The paper discusses algorithms used in disjoint literature-based discovery system at abroad-four correlation-mining algorithms,namely,Association Rules,TF-IDF,Z-Score and MIM,three different target-term ranking algorithms,namely,AMW,LTC-AMW and COH.we hope that it can provide references for domestic research about disjoint literature-based discovery to guide domestic researchers to develop discovery system,which is fit for Chinese document database,and to provide useful knowledge discovery tool for the medical and other fields.
