| 摘 要： | 以提高洪水资源利用率为目标,研究利用实时水雨工情及短期雨洪预报等综合信息的汛期库水位实时动态控制方法,即改进的预蓄预泄法.应用实例表明,在不降低水库上下游防洪标准的前提条件下,可使桓仁水库及梯级库群的发电效益明显增加.该综合信息的汛期库水位实时动态控制方法,对北方水资源短缺地区调节性能较高的大型水库(水电站)汛期实时调度,有较好的借鉴意义.

| Abstract: | Word sense disambiguation (WSD) is an important and difficult problem in natural language processing. A multi-strategy approach for WSD is proposed based on sememe relations in HowNet. The approach benefits from part-whole and attribute-host relations, which are the most basic and important sememe relations in HowNet. In addition, value-attribute relation, message structure and semantic relevancy are utilized to do disambiguation as supplement. The experimental results of SENSEVAL-3 Chinese WSD task show that the proposed method performs well in comparison with the official results. |
