A Comparison of Text-Based Methods for Detecting Duplication in Scanned Document Databases

This paper presents an experimental evaluation of several text-based methods for detecting duplication in scanned document databases using uncorrected OCR output. This task is made challenging both by the wide range of degradations printed documents can suffer, and by conflicting interpretations of what it means to be a duplicate. We report results for four sets of experiments exploring various aspects of the problem space. While the techniques studied are generally robust in the face of most types of OCR errors, there are nonetheless important differences which we identify and discuss in detail.     

Generalized Hamming Distance

Many problems in information retrieval and related fields depend on a reliable measure of the distance or similarity between objects that, most frequently, are represented as vectors. This paper considers vectors of bits. Such data structures implement entities as diverse as bitmaps that indicate the occurrences of terms and bitstrings indicating the presence of edges in images. For such applications, a popular distance measure is the Hamming distance. The value of the Hamming distance for information retrieval applications is limited by the fact that it counts only exact matches, whereas in information retrieval, corresponding bits that are close by can still be considered to be almost identical. We define a Generalized Hamming distance that extends the Hamming concept to give partial credit for near misses, and suggest a dynamic programming algorithm that permits it to be computed efficiently. We envision many uses for such a measure. In this paper we define and prove some basic properties of the Generalized Hamming distance, and illustrate its use in the area of object recognition. We evaluate our implementation in a series of experiments, using autonomous robots to test the measure's effectiveness in relating similar bitstrings.

体育院系学生蛙泳技术主因子结构初步研究

】运用Ｒ－型因子分析法研究影响体育院系游泳普修课学生掌握和提高蛙泳技术的主要因素,探索构成学生掌握和提高蛙泳技术的主因子结构,依据有关学科理论定量分析各主因子对掌握和提高蛙泳技术的影响程度及作用,结果表明：弹跳力与记忆综合特征因子、柔韧与动感综合特征因子分别是主因子结构中第一、第二主因子,它们对蛙泳技术的学习影响及作用相对较大。通过对这两个主因子中的高载荷因子的逐步回归计算,建立了蛙泳技术教学的数学模型,制定出学生身体素质、认知心理能力的评价等极标准,从而为控制教学过程和提高教学效果提供了参考信息和理论依据     

说话人识别中基于音素分类的数据选择方法

在说话人识别中,有效语音数据的选择是一个重要的预处理环节.常用的数据选择方法根据能量信息的强弱对有效数据进行提取,但在实际情况中能量的高低与语音数据并无必然联系.本文在对传统方法进行分析比较的同时引入语言学知识,提出基于辅音信息的有效数据选择方法.该方法通过对活动语音检测结果中音素识别结果进行分析,保留所有元音,对辅音进行筛选,去除无益于说话人识别的干扰辅音音素,从而实现对有效语 音数据的选取.实验表明,应用该方法得到的说话人识别结果,明显优于传统的基于能量的数据选择算法,如基于G.723.1标准的活动语音检测算法和近期提出的基于交叉熵顺序统计滤波的端点检测算法.     

Emotion recognition in fathers and mothers at high-risk for child physical abuse

Objective

The present study was designed to determine whether parents at high risk for physical child abuse, in comparison with parents at low risk, show deficits in emotion recognition, as well as to examine the moderator effect of gender and stress on the relationship between risk for physical child abuse and emotion recognition.

Methods

Based on their scores on the Abuse Scale of the CAP Inventory (Milner, 1986), 64 parents at high risk (24 fathers and 40 mothers) and 80 parents at low risk (40 fathers and 40 mothers) for physical child abuse were selected. The Subtle Expression Training Tool/Micro Expression Training Tool ( [Ekman, 2004a] and [Ekman, 2004b]) and the Diagnostic Analysis of Nonverbal Accuracy II (Nowicki & Carton, 1993) were used to assess emotion recognition.

Results

As expected, parents at high risk, in contrast to parents at low risk, showed deficits in emotion recognition. However, differences between high- and low-risk participants were observed only for fathers, but not for mothers. Whereas fathers at high risk for physical child abuse made more errors than mothers at high risk, no differences between mothers at low risk and fathers at low risk were found. No interaction between stress, gender, and risk status was observed for errors in emotion recognition.

Conclusions and practice implications

The present findings, if confirmed with physical abusers, could be helpful to further our understanding of deficits in processing information of physically abusive parents and to develop treatment strategies specifically focused on emotion recognition. Moreover, if gender differences can be confirmed, the findings could be helpful to develop specific treatment programs for abusive fathers.     

世纪之交的教育反思(二)

站在世纪之交的历史节点上,从不忽视职业教育的角度反观一个世纪以来的中国教育,在中国教育传统和外来教育影响的交变作用下,它经历着教育认识的嬗递与变革、教育方术的发展与富集、教育本体的颠覆与重构的巨大变化过程.这是中国社会由传统向现代整体演进的一个有机组成部分.这个过程远远没有结束.认识这个过程,对于正确把握我国教育的发展规律、创造出新世纪全面适应我国经济与社会发展和全体社会成员自身发展需要,包括普通教育和职业教育、基础教育和高等教育等各级各类教育的"让人民满意的教育",具有重要意义.
