【摘要】：随着MOOC教学方式的广泛使用以及蒙古文信息化的长足进步,蒙古语使用者迫切需要一个紧随MOOC教学发展进程、与世界主流平台一致的、功能完善的蒙古文MOOC平台。建立蒙古文MOOC平台可以推动蒙古文优质教学、学习资源的建设,可以促进内蒙古自治区蒙古文在线教育平台和资源建设的发展,对蒙古文信息处理标准和技术在教育领域的应用和发展产生积极的推动作用。本文阐述了蒙古文MOOC平台的特点,以平台功能需求为依据,总结并分析了基于Open ed X系统实现蒙古文MOOC平台需要解决的四个主要问题。本文的主要研究工作以这四个问题为出发点,深入分析了实现蒙古文MOOC平台的关键技术,并给出了改造方案与具体实现过程。本文具体研究工作如下:(1)针对构建蒙古文MOOC平台需要部署Open edX系统用于实际测试和开发的问题,采用云服务建立生产环境与开发环境,并基于LXC容器技术迁移到本地的方法,很好地解决了网络环境不良导致安装失败以及后期协同开发和本地化部署等问题。(2)针对Open edX用户接口显示蒙古文本出现文字断开、变形错误或乱码等问题,深入分析了浏览器显示蒙古文字符的原理,重新编写了Open edX界面字体渲染规则,引入了多种在线嵌入式字体作为用户接口的全局字体。(3)针对Open edX的原生用户界面不支持传统蒙古文的竖排显示的问题,深入分析了Open edX代码目录结构,充分利用Open edX的主题机制,深度改造了Open ed X的原生代码,建立了一套蒙古文主题,很好地解决了蒙古文竖排显示的问题。(4)针对Open edX系统的Markdown编辑器不支持蒙古文竖排显示与编辑的问题,本文通过分析编辑器的构成与显示编辑方式,给出了蒙古文Markdown编辑器的实现方法。(5)针对Open edX不支持传统蒙古文检索的问题,本文重点研究了国际标准编码蒙古文的构词特点,深入分析了ElasticSearch分布式搜索框架以及Lucene工具包,设计了一个符合蒙古文构词特点的蒙古文分析器插件,实现了基于ElasticSearch的国际标准编码蒙古文的分布式检索。
[Abstract]:With the extensive use of MOOC teaching methods and the rapid progress of Mongolian information technology, Mongolian language users urgently need to follow the development process of MOOC teaching, which is consistent with the mainstream platform of the world. Mongolian MOOC platform with perfect function. The establishment of Mongolian MOOC platform can promote the construction of Mongolian language quality teaching and learning resources, and promote the development of Mongolian online education platform and resources construction in Inner Mongolia Autonomous region. This paper expounds the characteristics of Mongolian MOOC platform, which is based on the functional requirements of the platform, and promotes the application and development of Mongolian information processing standards and technologies in the field of education. This paper summarizes and analyzes four main problems that need to be solved in the realization of Mongolian MOOC platform based on Open ed X system. The main research work of this paper takes these four problems as the starting point, and deeply analyzes the key technology of realizing Mongolian MOOC platform. The specific research work of this paper is as follows: 1) aiming at the problem that the Mongolian MOOC platform needs to deploy Open edX system for practical test and development, the production environment and development environment are established by cloud service. Based on the method of migrating LXC container technology to local area, the problems of installation failure caused by poor network environment and later collaborative development and localization deployment are solved.) for Open edX user interface, Mongolian text is disconnected. In this paper, the principle of Mongolian character display in browser is analyzed, and the rules of font rendering in Open edX interface are rewritten. This paper introduces several kinds of online embedded fonts as the global font of user interface. Aiming at the problem that the native user interface of Open edX does not support the vertical display of traditional Mongolian, the structure of Open edX code directory is analyzed in depth. By making full use of the theme mechanism of Open edX, the native code of Open edX has been deeply reformed, and a set of Mongolian themes has been established. In view of the problem that the Markdown editor of Open edX system does not support Mongolian vertical display and editing, this paper analyzes the composition and display editing mode of the editor. In order to solve the problem that Open edX does not support traditional Mongolian retrieval, this paper focuses on the word-formation characteristics of international standard coding Mongolian, and deeply analyzes the ElasticSearch distributed search framework and Lucene toolkit. In this paper, a Mongolian word-formation plug-in is designed, and the distributed retrieval of Mongolian language based on ElasticSearch is realized.
