摘　　要：随着5G的商用,短信功能将逐渐被5G消息所替代。5G消息单条文本消息长度将可达上万字。现有关键字组合策略将由于文本长度的增加产生误匹配。本文设计了一种约束上下文区间的关键词组合策略,并给出了详细的实现方法。使用该方法可以高效实现在特定长度的上下文区间内进行关键词组合策略匹配,同时该方法能够截取命中策略的关键文本片段,帮助人工审核人员进行快速审核。With the commercialization of 5G,short messages will be replaced by 5G messages.The length of a single 5G message text message will reach tens of thousands of words.Existing keyword combination strategies will cause mismatches due to the increase in text length.This paper designs a keyword combination strategy that constrains the context interval.And gives a detailed implementation method.Using this method can effi ciently achieve keyword combination strategy matching in a specifi c length context interval.At the same time,this method can intercept the key text fragments of the hit strategy and help manual reviewers to conduct quick review.
