摘要：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一used inverted index technology, and then describes the Sentence inverted index and related algorithms for the teaching of foreign language writing.  Finally, it designs and implements a set of foreign language teaching aided Authoring System, which is based on these algorithms. The experiment design and analysis show that the Big-data-based Inverted Index technology can be well applied to foreign language writing instruction and it has obvious advantages over the traditional method.
