基于大数据倒排索引技术的外语写作教学辅助系统研究与实现

Research and Implementation of Foreign Language Teaching Aided Authoring System Using Big-data-based Inverted Index Technology

大数据及其相关技术的发展给众多领域带来了诸多机遇与挑战,教育领域也不例外。本文首先介绍了大数据场景下常用的倒排索引技术,其次设计了面向外语写作教学的句子倒排索引算法,接着基于该算法设计并实现了一套外语写作教学辅助系统。应用分析与实验表明,大数据倒排索引技术能够较好地应用于辅助外语写作教学,同时较之于传统的方法也有着明显的优势。

The development of big data and related technologies has opened up a lot of opportunities and challenges to many fields, including education. This paper firstly introduces the Big-data-based inverted index technology, and then describes the Sentence inverted index and related algorithms for the teaching of foreign designs and implements a set of foreign language teaching aided Authoring System, which The experiment design and analysis show that the Big-data-based Inverted Index technology language writing instruction and it has obvious advantages over the traditional method language writing. Finally, it is based on these algorithms. can be well applied to foreign language writing instruction and it has obvious advantages over the traditional method.
