Raw data extraction from electrocardiograms with Portable Document Format

During the last two decades there has been a thorough research and development of standards and protocols in order to cope with different electrocardiogram formats from heterogeneous acquisition systems. Despite the efforts of public and private consortiums on creating a standardized electrocardiogram (ECG) storage format, there is still not a single one. Indeed, there is also the necessity of access to raw data of the ECGs previously acquired. Most of these documents have been saved as Adobe PDF files, since for medical staff it is an easy format for later visualization. However, this format presents difficulties when trying to access original raw data for subsequent studies and signal analysis. In this manner, this paper presents an application that obtains plain numerical data from ECG files stored with PDF format. Data can also be exported to one of the most common file formats in existence, to be easily accessed thereafter.     

Near-duplicate document image matching: A graphical perspective

A near-duplicate document image matching approach characterized by a graphical perspective is proposed in this paper. Document images are represented by graphs whose nodes correspond to the objects in the images. Consequently, the image matching problem is then converted to graph matching. To deal with the instability of object segmentation, a multi-granularity object tree is constructed for a document image. Each level in the tree corresponds to one possible object segmentation, while different levels are characterized by various object granularities. Some graphs can be generated from the tree and the objects associated with each graph may be of different granularities. Two graphs with the maximum similarity are found from the multi-granularity object trees of the two near-duplicate document images which are to be matched. The encouraging experimental results have demonstrated the effectiveness of the proposed approach.     

KHATT: An open Arabic offline handwritten text database

A comprehensive Arabic handwritten text database is an essential resource for Arabic handwritten text recognition research. This is especially true due to the lack of such database for Arabic handwritten text. In this paper, we report our comprehensive Arabic offline Handwritten Text database (KHATT) consisting of 1000 handwritten forms written by 1000 distinct writers from different countries. The forms were scanned at 200, 300, and 600 dpi resolutions. The database contains 2000 randomly selected paragraphs from 46 sources, 2000 minimal text paragraph covering all the shapes of Arabic characters, and optionally written paragraphs on open subjects. The 2000 random text paragraphs consist of 9327 lines. The database forms were randomly divided into 70%, 15%, and 15% sets for training, testing, and verification, respectively. This enables researchers to use the database and compare their results. A formal verification procedure is implemented to align the handwritten text with its ground truth at the form, paragraph and line levels. The verified ground truth database contains meta-data describing the written text at the page, paragraph, and line levels in text and XML formats. Tools to extract paragraphs from pages and segment paragraphs into lines are developed. In addition we are presenting our experimental results on the database using two classifiers, viz. Hidden Markov Models (HMM) and our novel syntactic classifier.

二维条形码在机关公文管理中的应用

办公自动化系统的发展和应用,对于政府转变职能,提高办公效率起到了举足轻重的作用,但是在实际应用过程中也碰到了很多问题,其中之一就是对公文的管理。传统办公自动化系统的目标是实现办公全过程的＂无纸化＂,即把纸质文件转化为电子文件进行流转。但在目前国情下,要一步实现无纸化办公,还面临很多困难,因此政府机关不得不将纸质文件流和电子文件流并行运行,从而导致需要分发交换的纸质文件和文件的电子信息脱节。通过将条码技术引入到公文管理中,生成含有文件信息的二维条码,从而实现纸质文件和文件的电子信息完全同步。     

归档文件整理规则实施后的思考

《归档文件整理规则》实施后,文书档案管理方式发生了变化,对档案的整理在一定程度上产生了影响,应该在实施过程中总结经验,在探索新方法的过程中加以完善。     

基于组件技术支持产品协同设计的中间文档管理及实现

在产品协同设计过程中始终存在大量的设计中间文档，对中间文档的管理是保证协同设计顺利进行的关键环节。中间文档的管理涉及到两个操作，对文件的操作和对文件附加属性的操作，使用组件技术，将这两个分离的操作封装在一起，提高了操作的一致性和安全性，并使得协同设计软件的开发更加便捷。     

改进的软件错误报告自动分类算法

软件错误报告的自动分类能够节省大量人力和时间,然而用户提交的错误报告主观性较强,对错误报告的描述较随意,造成自动分类的效率低下。为此,基于传统的词频-逆向文件频率( TF-IDF )算法,结合文档内词条频度与词条在同类别及不同类别文档中的分布情况,提出2种特征降维的改进算法,降维后再对词条进行权值处理,进一步提高特征降维的效果。实验结果表明,应用该算法得到的错误报告自动分类在精确率、召回率、F1值和准确度等指标上比现有算法都有明显提高。
