基于实例的汉语语义超常搭配的自动发现

搭配在语言信息处理中具有重要的应用价值,通常我们主要关注符合语法规则的常规搭配。实际上,语言中还存在着大量的语法上符合规则而语义上不符合常规认知的语义超常搭配现象,而这样的现象与语言的隐喻表达和思维有着密切的联系,对自然语言理解将产生重要的影响。本文面向汉语隐喻理解来研究文本中语义超常搭配的自动发现方法,从汉语语义超常搭配判断的心理机制出发,提出了基于实例的汉语语义超常搭配识别的量化计算方法。实验以动词为中心的搭配语料为测试集,语义超常搭配识别的召回率为80. 7 % ,准确率为81. 5 %。实验结果表明本文所给出的基于实例语义超常搭配判断的办法是切实可行的。国家自然科学基金资助(项目号:60373080) 和浙江大学985 工程资

Studies on Cu-Ni alloy electroless plating using sodium hypophosphite as reductant

研究了以次磷酸钠为还原剂的化学镀铜过程。分析了温度、pH、硫酸镍含量对化学镀铜沉积速率的影响及镀层的表面形貌和结构。结果表明,沉积速率随着镀液温度、pH和N i离子浓度的提高而增大。镀层组分含量和XRD实验结果表明镀层为铜镍合金,呈面心立方结构,晶面间距d与晶胞参数a与标准Cu-N i的相比略大。SEM实验表明,镀层表面形貌为团粒状,颗粒大小较不均匀。The process of the electroless copper plating(using) sodium hypophosphite as reductant was studied.The influences of temperature,pH,nickel sulphate content on deposition rate of copper electroless plating as well as the surface morphology and structure of the deposit were(analyzed.)The results show that the deposition rate is(accelerated) with increasing bath temperature,pH value and the concentration of nickel ion.Both deposit composition and XRD results indicate that the deposits are Cu-Ni alloy with face-centered cubic structure.Its structural parameters of d and a are slightly larger than that of the standard Cu-Ni(alloy).SEM experiment displays that the deposit has a(surface) morphology of granular structure with uneven grain sizes.国家科技攻关计划项目(2004BA325C

The Identical Nature of Psychological Process of Metaphor Recognition

本文从计算角度探讨隐喻识别问题。首先模拟人类隐喻思维过程构建了"识别、分析、释义"三阶段隐喻机器理解模式,并提出了隐喻识别心理过程的无差别性假设,即不同隐喻句皆通过句内成分之间指称或搭配之异常来触发人们的辨识。该假设直观地体现为人们在识别不同隐喻句时,反应时无明显差异,而在解释隐喻含义时,反应时则表现出明显差异。该假设得到了反应时对比实验结果的支持。隐喻识别心理过程的无差别性为隐喻计算提供了一种新的解决思路和方法。This paper discussed metaphor recognition from a computational view. A mode with three stages of machine-understanding of metaphor which is most close to human thoughts was first suggested. This paper pointed out an identical nature of the psychological process of metaphor recognition that different metaphors were triggered following the same way, that is, they were triggered and prompted people to recognize them by their anomalous semantic collocation of sentence components. A visible appearance of the nature was that the difference between different metaphors' reaction time was very small in the recognition stage, but very significant in the analysis and interpretation stages. The experiment results supported the hypothesis. The identical nature of the psychological process of metaphor recognition introduced a new method research on metaphor computation.国家自然科学基金资助(项目号:60373080
