Synchrotron radiation lithography (SRL) and mask techniques are developed, and the micro-electro-mechanical systems (MEMS) techniques are also investigated at NSRL. In this paper, some results based on SRL and MEMS techniques are reported, and sub-micron and high aspect ratio microstructures are given. Some micro-devices, such as microreactors are fabricated at NSRL.展开更多
研究了中文名词性谓词的语义角色标注(semantic role labeling,简称SRL).在使用传统动词性谓词SRL相关特征的基础上,进一步提出了名词性谓词SRL相关的特征集.此外,探索了中文动词性谓词SRL对中文名词性谓词SRL的影响,并且联合谓词自动...研究了中文名词性谓词的语义角色标注(semantic role labeling,简称SRL).在使用传统动词性谓词SRL相关特征的基础上,进一步提出了名词性谓词SRL相关的特征集.此外,探索了中文动词性谓词SRL对中文名词性谓词SRL的影响,并且联合谓词自动识别实现了全自动的中文名词性谓词SRL.在中文NomBank上的实验结果表明,中文动词性谓词的SRL合理使用能够大幅度提高中文名词性谓词的SRL性能;基于正确句法树和正确谓词识别,中文名词性谓词的SRL性能F1值达到了72.67,大大优于目前国内外的同类系统;基于自动句法树和自动谓词识别,性能F1值为55.14.展开更多

Current SRL assessment approaches cannot be applied to handle inadequate information as the input. The ER-based approach is proposed to synthesize inadequate input information and an integration-centric perspective is applied to reduce the computational complexity. Two case studies are performed to validate the efficiency of the proposed approach. And these studies are also performed to study how the inadequate information will affect the assessment result. And the differences caused by the system＇s structure. The importance of the system＇s structure in the SRL assessment is demonstrated and the contributions made in this study are summarized as conclusions.展开更多
