文本语法与历史遗产类旅游文本的英译

本文侧重于人文景观中的历史遗产类旅游文本的英译。本文尝试对从Werlich文本语法入手,探讨如何通过有效的翻译提高历史遗产类旅游文本的效果。在功能翻译原则指引下,对文本的外部制约和内部制约进行分析对比。从而总结出目前历史遗产类旅游文本存在的不足。     

一种新的视频文本定位方法

本文提出了一种基于投影分析与支持向量机学习相结合的文本定位方法。首先采用投影分析的方法将可能的文本区域提取出来,然后再采用基于支持向量机学习的方法将提取出来的文本区域中的虚假文本区域排除掉。采用投影分析的方法时先将图像的边缘提取出来,再使用一些形态学的操作使边缘聚集,最后采用多次投影定位出文本区域。在使用支持向量机进行文本分类时本文采用了小波,角点,扫描线和区域内边缘点的重心位置等特征。实验表明该方法比单纯的基于边缘的方法要好。     

自动校对中现代藏文音节字研究

现代藏文自动校对中,对音节字（ ）的校对是其基础。在藏文文本中音节字是用音节点进行间隔的,由于藏文二维的书写特征和音节字形成过程中与其构件之间严格的搭配规则等诸多问题,使得对它的校对又区别于任何一种文字。文章介绍了音节字的构件、结构和搭配规则等问题,列举了藏文音节字中的错误类型,并针对其特殊性给出了一个特有的音节字校对的流程和方法。     

文本挖掘综述

文本挖掘是对一个非结构化文本信息进行分析从而获取用户关心或感兴趣,有潜在实用价值知识的过程。本文首先介绍了文本挖掘的定义和研究现状,之后文本挖掘一般处理过程,着力于文本分类和文本聚类的一般过程,最后展望了今后的研究目标。     

基于知网语义相似度计算的特征降维方法研究

针对文本分类处理中的高维度问题,结合知网语义词典,提出了一种新的特征降维处理方法.通过计算特征词汇之间的语义相似度,将原有特征集分成若干特征词集;同一词集内的特征词语义彼此间相似;而不同词集的特征词彼此间相似度比较小.将同一特征词集内的词汇权重相加,从而突出同义词以及近义词对文本分类的贡献,并可以大大降低文本比较的特征维数.实验结果表明,利用该方法在文本分类中得到了较好的分类准确率和分类性能.     

Indexing text with approximate q-grams

We present a new index for approximate string matching. The index collects text q-samples, that is, disjoint text substrings of length q, at fixed intervals and stores their positions. At search time, part of the text is filtered out by noticing that any occurrence of the pattern must be reflected in the presence of some text q-samples that match approximately inside the pattern. Hence the index points out the text areas that could contain occurrences and must be verified. The index parameters permit load balancing between filtering and verification work, and provide a compromise between the space requirement of the index and the error level for which the filtration is still efficient. We show experimentally that the index is competitive against others that take more space, being in fact the fastest choice for intermediate error levels, an area where no current index is useful.

Landscape of ROD9 Island: Functional annotations and biological network of hypothetical proteins in Salmonella enterica

Salmonella, an Enterobacteria is a therapeutically important pathogen for the host. The advancement of genome sequencing of S. enterica serovar Enteritidis have identified a distinct ROD9 pathogenic island, imparting virulence. The occurrence of 17 ROD9 hypothetical proteins, necessitates subsequent bioinformatics approach for structural and functional aspects of protein-protein relations or networks in different pathogenic phenotypes express. A collective analysis using predictive bioinformatics tools that includes NCBI-BLASTp and BLAST2GO annotated the motif patterns and functional significance. The VFDB identified 10 virulence proteins at both genomic and metagenomic level. Phylogenetic analysis revealed a divergent and convergent relationship between 17 ROD9 and 41 SP-1 proteins. Here, combining a comprehensive approach from sequence based, motif recognitions, domain identification, virulence ability to structural modelling provides a precise function to ROD9 proteins biological network, for which no experimental information is available.
