标准化与规范化网络信息共享服务的框架结构设计

信息共享是良好的个性化服务的基础，而标准化与规范化则是信息全面共享的的前提，本文提出建立相应的信息共享服务标准的重要性，详细论述了标准化与规范化的信息共享服务，并在此基础上初步完成了标准化与规范化信息共享服务的框架结构设计。     

试论同义词里的同一语素——以张志毅《简明同义词典》为个案的研究

同一语素是指出现在一组同义词中的音同形同意义上相同或相近的语素,同一语素在同义词里大量存在,是一种重要的语言现象。同一语素在意义上可分为相同和相近两种类型。它们在同义词里呈多种分布格式,但分布上有对应性。同一语素在同义词里的出现也是有条件限制的。     

室温固相反应制备CdS纳米粒子

以牛血清白蛋白为稳定剂,CdSO4·8H2O、硫脲、NaOH室温固相反应制备CdS,用XRD、TEM、原子力对粒子进行表征表明,得到单分散立方相球状CdS纳米粒子。还表明。牛血清白蛋白加入的量及加入方式对粒子的大小、粒径分布、分散程度有影响。随牛血清白蛋白加入的量的增加,粒子变小,粒径分布更均匀,分散程度提高;且在固相反应物中加入牛血清白蛋白一起研磨比粒子制成后水相中再加入牛血清白蛋白更有利于粒子的粒径分布均匀和分散。     

美国在“马亚克斯”事件中的情报失误及其启示

[目的/意义]1975年5月12日,柬埔寨海军在泰国湾扣押了美国商船"马亚克斯号",时任总统福特领导下的美国政府最终采用武力方式夺回了船只及船员。然而,美国在此次营救行动中的情报工作存在较多失误。研究此次行动中的情报方面的失误,能为改进危机预警与管控中的情报工作提供参考借鉴。[方法/过程]该研究利用解密的美国军事及外交档案,系统梳理了美军在"马亚克斯"事件中出现的事前威胁研判与预警、事后意图判断与战略选择、战场情报搜集与分析、情报上报分发等多个失误及其成因。[结果/结论]美国在这次行动中的情报失误启示我们,应当提升战略预警能力,准确预判风险;注重情报的提前储备,有力支持危机决策与行动;优化情报报送分发机制,充分发挥情报价值。

Improving relational similarity measurement using symmetries in proportional word analogies

Measuring the similarity between the semantic relations that exist between words is an important step in numerous tasks in natural language processing such as answering word analogy questions, classifying compound nouns, and word sense disambiguation. Given two word pairs (A, B) and (C, D), we propose a method to measure the relational similarity between the semantic relations that exist between the two words in each word pair. Typically, a high degree of relational similarity can be observed between proportional analogies (i.e. analogies that exist among the four words, A is to B such as C is to D). We describe eight different types of relational symmetries that are frequently observed in proportional analogies and use those symmetries to robustly and accurately estimate the relational similarity between two given word pairs. We use automatically extracted lexical-syntactic patterns to represent the semantic relations that exist between two words and then match those patterns in Web search engine snippets to find candidate words that form proportional analogies with the original word pair. We define eight types of relational symmetries for proportional analogies and use those as features in a supervised learning approach. We evaluate the proposed method using the Scholastic Aptitude Test (SAT) word analogy benchmark dataset. Our experimental results show that the proposed method can accurately measure relational similarity between word pairs by exploiting the symmetries that exist in proportional analogies. The proposed method achieves an SAT score of 49.2% on the benchmark dataset, which is comparable to the best results reported on this dataset.     

Gender,Rhetoric, and International Political Systems: Angela Merkel's Rhetorical Negotiation of Proportional Representation and Party Politics

This article assesses the ways in which electoral systems present unique rhetorical challenges for women running for elective office, using German Chancellor Angela Merkel as a case study. In proportional systems, much of the rhetorical work occurs at the level of the party, requiring the political woman to capitalize on the rhetorical resources of the party structure in which she finds herself, advancing to party leadership, and eventually localizing the national election via the party structure. However, Merkel's performance demonstrates that the presence of women and of feminine norms of communication can sometimes mask the hegemonic masculinity that continues to govern democratic electoral systems. The authors conclude by considering the utility of the theory of “feminine style.”
