Learning regional transliteration variants     

Jin-Shea Kuo  Haizhou Li 《Information processing & management》2012,48(1):154-169

This paper conducts an inquiry into regional transliteration variants across Chinese speaking regions. We begin by studying the social association of regional transliterations, followed by postulating a computational model for effective transliteration extraction from the Web. In the computational model, we first propose constraint-based exploration by incorporating transliteration knowledge from transliteration modeling and predictive query suggestions from search engines into query formulation as constraints so as to increase the chance of desired transliteration returns in learning regional transliteration variants. Then, we study a cross-training algorithm, which explores the attainably helpful information of transliteration mappings across related regional corpora for the learning of transliteration models, to improve the overall extraction performance. The experimental results show that the proposed method not only effectively harvests a lexicon of regional transliteration variants but also mitigates the need of manual data labeling for transliteration modeling. We also carry out an investigation into the underlying characteristics of regional transliterations that motivate the cross-training algorithm.  相似文献   

User-satisfaction based bandwidth allocation for transmission of multiple sources of human perceptual data     

Cheng-Chun Chang  Tien-Ying Kuo  Yi-Chung Lo  Heung-No Lee  David Askey  Zhi-Hong Mao 《Journal of The Franklin Institute》2012,349(3):879-890

In recent years, more and more point-to-point communication systems involve simultaneous transmission of multiple sources of human perceptual data over a single communication medium. For example, in a teleoperation system or a telerobotic system, streams of video, audio, and haptic data need to be sent from a field place to a remote human operator. Each type of data demands a certain range of transmission rate. This creates conflicts among these data when the available bandwidth is limited.In this paper we study the bandwidth allocation for multiple sources of human perceptual data transmitted over a rate-limited communication channel. We aim to maximize the overall user satisfaction in the data transmission, and formulate an optimization problem for the bandwidth allocation. Using either the logarithmic or exponential form of human perceptual satisfaction function, we are able to derive closed-form solutions for the optimization problem. We show that the optimal bandwidth allocation for each type of data is piecewise linear with respect to the total available bandwidth.  相似文献   

“后扶贫时代”农村学校阻贫成效评估及长效保障——基于秦巴山连片特困地区五县的实证     

赵阔  赵丹 《当代教育论坛》2021,(2):19-29

农村学校是贫困地区教育扶贫中的关键角色.研究基于多元贫困理论和政策文本分析,构建资源输入、内涵发展和系统改进三维12类农村学校阻贫成效评估体系.在此基础上,对秦巴山连片特困地区五县的实证调查发现,农村学校在贫困生补助、办学资金增加、设施设备改善、贫困生陪伴关怀与贫困生身心素质培养等方面的阻贫成效显著;但在优质教育资源共享、贫困生营养健康支持、学业质量提升、学校软环境与家庭观念改善等方面存在不足,特别是在农村教师直接参与社区扶贫工作等方面存在政策执行偏差.“后扶贫时代”应继续加强师资改善、校长教师培训工作,优化义务教育优质资源共享机制,整体提升农村学生营养健康水平和学业质量,合理扩展农村学校对家庭和社区的阻贫功能.  相似文献

潘海毅  李阔  王毅 《江西电力职业技术学院学报》2021,34(6):3-5

为解决现行变电企业选址方法在实际应用中存在相关系数较低、选址规划位置不合理等问题,结合当前现有变电站配电网与负荷情况,开展110kV变电站选址方法探究.基于现状配电网与负荷情况的选址规划模型构建、模糊层次分析的110kV变电站选址、规划结果一致性检验,提出一种全新的选址方法.实验证明,新的选址方法在实际应用中得出的结果与现行变电站相比一致性更高,更能够满足现有变电站配电网和负荷运行需要.  相似文献   

Effects of applying a VR-based two-tier test strategy to promote elementary students’ learning performance in a Geology class     

Shao-Chen Chang  Ting-Chia Hsu  Wei-Chen Kuo  Morris Siu-Yung Jong 《British journal of educational technology : journal of the Council for Educational Technology》2020,51(1):148-165

Science and technology are driving people’s life changes, including education and the environment. Many scholars have attempted to import technology into the classroom to help students learn in different subjects. However, students often need assistance with unfamiliar learning approaches and learning environments. This study proposed a non-immersive virtual reality (VR) guidance system combined with a two-tier strategy to help students learn geology knowledge. Two groups of students used different learning approaches: the experimental group students were guided by the two-tier test VR guidance system, and the control group students learned with the conventional VR guidance system. According to the experimental result, the two-tier test VR guidance system not only improved the students’ learning achievement in natural science, but also enhanced their learning motivation. In addition, according to the sequential results, we found that VR learning materials or environmental resources can help students answer questions and solve problems more effectively.  相似文献

论北岩书院的理学教育精神     

张阔 《四川教育学院学报》2006,22(5):11-14

北岩书院与二程理学渊源素深，它是程颐注《易》讲学之所，也是“涪陵学派”的发源地，更是二程理学大规模向巴蜀传入的重要场所。自程颐以后，有许多程朱理学大师也在此讲学研究，从而具有了深厚的理学教育精神。  相似文献   

客观知识体系中语义关系相邻共现规律研究   总被引：1，自引：1，他引：0  

裘江南  张彬  王慧丽  张阔 《情报学报》2012,31(2)

客观知识体系是由概念为节点和语义关系为边组成的大规模语义网络,其中普遍存在着大量的语义关系相邻共现现象,却一直未引起学者的关注.本文针对语义关系相邻共现现象进行了定义与分析,并根据语义关系共现的特点和基于前人的共现分析方法,选择了语义关系相邻共现强度函数,并以WordNet为背景计算其语义关系相邻共现矩阵.通过分析该共现矩阵发现了单个语义关系间的共现规律,并依据语义关系分类进一步挖掘了一类语义关系与其他关系间的共现规律.这些语义关系相邻共现规律的发现为判断语义关系组合的可能性和有效性提供了客观依据,为研究语义关系组合打下了很好的基础.  相似文献
