Upon this foundation,a corpus-based algorithm was designed and implemented to acquire and filter binary semantic pattern rules automatically. In the algorithm,a data mining method for cross-level association rules is adopted,which is guided by metarule,to find the semantic laws of word combinations in Chinese phrase corpus. Then statistic results are used to filter the findings. In the end,the remains are transformed into binary semantic pattern rules.

在此基础上，本文设计并实现了基于语料库的二元语义模式规则自动挖掘和优选算法，该算法先采用数据挖掘中元规则制导的交叉层关联规则挖掘方法，自动发现汉语短语熟语料库中词语两两组合的语义规律，再根据统计结果自动优选后转换生成候选二元语义模式规则集。
