【摘要】：微软公司为Windows和Apple Macintosh操作系统开发了一套办公软件，，是由Microsoft为Windows和Apple Macintosh操作系统的电脑而编写和运行的一款试算表软件。Excel是微软办公套装软件的一个重要的组成部分。 Excel具有开放性、自描述性它可以进行各种数据的处理、统计分析和辅助决策操作，广泛地应用于管理、统计财经、金融等众多领域。这一性能使它成为在Internet上进行数据存储和数字化信息传播的理想文档格式。然而人们常常需要对Excel文档内容进行引用分析或者编辑。基于目前移动互联网的火热化，移动办公的普及和Excel在数据挖掘和搜索引擎中数据源的地位。这就需要对Excel文件格式的内容进行解析，将其有效内容提取出来，或移植到移动设备。并且根据移动设备的特殊性设计新的抽取算法和呈现算法。本课题便是着眼于这一核心功能进行实现的。本系统主要由两个功能模块组成，其一是将Excel文档内容中的数据信息提取出来，其二是将Excel文档中的数据与图像内容进行还原与呈现。本文着重讨论Excel的数据抽取方法，其中包括Excel内容流提取、字符集的转化以及数据信息抽取。利用的技术主要为解释器技术。最后，本文指出了Excel格式在未来发展的趋势,比如垂直搜索的文本挖掘和语义网络。
[Abstract]:Microsoft has developed a suite of office software for the Windows and Apple Macintosh operating systems. Excel is a spreadsheet software written and run by Microsoft for Windows and Apple Macintosh operating system computers. Excel is an important part of Microsoft office suite software. Excel is open. It can be used in many fields such as management, statistics, finance and so on. This performance makes it an ideal document format for data storage and digital information dissemination on the Internet. However, people often need to analyze or edit the contents of Excel documents. Based on the current popularity of mobile Internet, the popularity of mobile office and Excel in data mining and search engine data source status. It is necessary to parse the content of Excel file format, extract its effective content, or transplant it to mobile device. A new extraction algorithm and a presentation algorithm are designed according to the particularity of mobile devices. This subject is focused on the implementation of this core function. The system is mainly composed of two functional modules, one is to extract the data information from the Excel document content, the other is to restore and present the data and image content in the Excel document. This paper focuses on the data extraction methods of Excel, including Excel content stream extraction, character set transformation and data information extraction. The main technology used is interpreter technology. Finally, this paper points out the trend of Excel format in the future, such as vertical search text mining and semantic network.
