融合关键词概率映射的汉越低资源跨语言摘要

在低资源汉越跨语言摘要任务中，由于标注的汉越对齐数据稀缺，较难实现跨语言语义对齐.鉴于此，提出一种融合关键词概率映射的低资源跨语言摘要方法，首先利用源语言关键词实现关键信息的提取，然后基于概率映射对将源语言关键词映射到目标语言，最后基于指针网络将映射的目标语言关键词融入到摘要生成过程中.在构建的汉越跨语言摘要数据集上的实验结果表明，相比于直接的端到端的方法，融入关键词概率映射信息可以有效地提升低资源跨语言摘要的质量.     

重叠式功能跨语言研究综述

重叠式功能跨语言研究在国内外已经有了相当丰硕的研究成果,但还存在研究的对象界定模糊、对具体语言中重叠式能产性及跨语言复现率的关注不足、对不同来源重叠式的区别不够清晰等问题。另外,重叠式多功能之间的语义引申也是重叠式功能跨语言研究中一个有待深入研究的课题。     

语言的性别差异及其对跨性别交际的影响

男性和女性在跨性别交际中常常出现交际失误。语言的性别差异往往是引起这些交际失误的原因。因为不同性别的交际者在用词、表达方式和会话风格等方面存在着差异。也即,男性和女性因受不同性别文化的影响,各自形成一套不同的语言风格。为避免交际误解,应培养跨性别交际的敏感性,这样才能达到有效交际的目的。     

跨语言句法启动中语义与句法的双语表征机制--以题元角色为视角的实证研究

本研究借鉴Potter和Lombardi的句法启动及语言间句法启动的实验范式，针对高、低水平英语学习者设计了不同的句法启动，在启动句和目标句的题元顺序一致与不一致的条件下进行汉-英（ C-E）句法启动实验，旨在考察句子产生过程中的语义功能及中国英语学习者句法表征的内在机制。研究结果证明了句子加工过程中的语义作用，发现启动句和目标句的题元顺序在句法启动的效应大小中起了主导作用，同时也证实了中国学习者的语言水平以及母语对其外语通达效率存在影响。     

英语教学与跨文化教育

解码大学英语词汇——简论跨词类派生词

由于受英汉词类细分不对应和各自语言表述习惯内在差异的影响，易形成汉语学习者习得英语时的盲点或弱视区，即语言缺失。概括出包括基于动词词根的形容词／副词在内的六种跨词类派生词。这六类词既丰富了所属词族又可解码英语词汇，并能言简意赅地对接汉语。     

英汉跨语言学习中L1与L2双向性语言迁移模式研究

在跨语言学习与研究中,语言迁移现象时常发生,学习者在语言学习过程中常受到第一语言(L1)与第二语言(L2)之间的迁移影响,即L1→L2、L2→L1的语言正迁移与负迁移影响。以"概念整合理论"与"跨语言影响理论"为理论指导,对英汉跨语言学习中的L1与L2双向性语言迁移模式进行了深入研究。     

基于词典的藏汉跨语言检索系统研究

针对跨语言检索中查询翻译歧义问题,文章从藏汉跨语言检索的特点出发,采用了平衡翻译(Balanced Transation)方法,减少了歧义翻译数量,提高了翻译的准确度.在文档索引上,为了弥补藏文分词对于命名实体识别的不足,采用了4元组的索引方法,明显提高了检索的速度和准确度.     

跨性别交际失误的社会语言学分析

从语言变异的角度对跨性别交际失误现象进行社会语言学分析,社会文化因素的影响造成男女两性话语风格的不同,进而影响彼此的交流。在对《老友记》部分语料统计分析的基础上,我们发现社会的变化导致两性差异的缩小,两性话语风格随之变化,有些方面甚至出现与以往相反的趋势。两性话语风格的趋同将有助于减少跨性别交际中的失误现象。     

跨性别交际中的语言性别差异

语言性别差异普遍存在于人类的语言活动中。两性在使用语言进行交际时,呈现出不同的特点,而造成这些差异的原因涉及到生理、社会地位和亚文化模式等方面。为避免交际失误,应当正确认识语言的性别差异,培养跨性别交际的意识,从而顺利进行跨性别交际。     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.     

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。

An on-line scaling method for improving scalability of a database cluster

The explosive growth of the Internet and database applications has driven database to be more scalable and available, and able to support on-line scaling without interrupting service. To support more client's queries without downtime and degrading the response time, more nodes have to be scaled up while the database is running. This paper presents the overview of scalable and available database that satisfies the above characteristics. And we propose a novel on-line scaling method. Our method improves the existing on-line scaling method for fast response time and higher throughputs. Our proposed method reduces unnecessary network use, i.e. , we decrease the number of data copy by reusing the backup data. Also, our on-line scaling operation can be processed parallel by selecting adequate nodes as new node. Our performance study shows that our method results in significant reduction in data copy time.     

An improved R-tree based on childnode''s probability

R-Tree is a good structure for spatial searching. But in this indexing structure,either the sequence of nodes in the same level or sequence of traveling these nodes when queries are made is random. Since the possibility that the object appears in different MBR which have the same parents node is different, if we make the subnode who has the most possibility be traveled first, the time cost will be decreased in most of the cases. In some case, the possibility of a point belong to a rectangle will shows direct proportion with the size of the rectangle. But this conclusion is based on an assumption that the objects are symmetrically distributing in the area and this assumption is not always coming into existence. Now we found a more direct parameter to scale the possibility and made a little change on the structure of R-tree, to increase the possibility of founding the satisfying answer in the front sub trees. We names this structure probability based arranged R-tree (PBAR-tree).     

Integrating GIS Web services based on mediating architecture

The geographic information service is enabled by the advancements in general Web service technology and the focused efforts of the OGC in defining XML-based Web GIS service. Based on these models, this paper addresses the issue of services chaining,the process of combining or pipelining results from several interoperable GIS Web Services to create a customized solution. This paper presents a mediated chaining architecture in which a specific service takes responsibility for performing the process that describes a service chain. We designed the Spatial Information Process Language (SIPL) for dynamic modeling and describing the service chain, also a prototype of the Spatial Information Process Execution Engine (SIPEE) is implemented for executing processes written in SIPL. Discussion of measures to improve the functionality and performance of such system will be included.
