The paper summarizes theories and practices concerning data mining at the beginning. According to actual conditions of data forecasting, the paper particularizes two basic tasks in data mining, namely, exploring data analysis and forecasting modeling for classification, and employs them in load forecasting practically. Then a special short-term load-forecasting arithmetic is forwarded based on the former work, which can efficiently take into account weather effects on the load, and hence improve the accuracy of load forecasting.

The basic concept and general knowledge of data mining were given firstly, and the characteristics and research methods of data mining procedure were explained based on the test-driving database of WS9 aero-engines. Rough set and decision tree, these two classification mining methods were used to extract decision rules, regression analysis was utilized to find the relationship between variables, and the tendency also was predicted.

On the one hand, there are lots of association rules theory of application-oriented is waiting for explore and creative in these big theory framework; on the other hand, with the development of data mining and relevance technology, it must will birth new mining theory, and it will have impetus to some particular application, it may merge particular application target, such as marketing, custom relationship managements electronic business.

一方面，在这些大的理论框架下有许多面向实际应用目标的关联规则挖掘理论等待探索和创新；另一方面，随着数据挖掘技术本身和相关技术的发展，新的挖掘理论的诞生是必然的，而且可能对特定的应用产生推动作用，可能融合特定的应用目标，如市场营销、CRM、电子商务等。

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。

A simple, but typical, process might include prepro- cessing data, applying a data-mining algorithm, and visualizing the mining results.
