我有以下聊天对话：
聊天开始时间：2018 年 4 月 2 日，星期一，10：23：30 (+0100) 聊天来源：GB - 我的帐户(已登录) 代理纳文 P ( 1s ) 纳文： 感谢您联系XYZ，您正在与纳文交谈。我能帮上什么忙？ ( 34秒 ) 访客： 您好，我刚刚从百联宽带切换到晶圆厂光纤 ( 39秒 ) 纳文： 嗨 ( 42秒 ) 纳文：早上好。 ( 47秒 ) 访客：我发现灿烂的宽带太慢了 ( 52秒 ) 纳文： 今天我能帮你什么？ ( 1 分钟 1 秒 )访客：我们被告知将是切换的一天 ( 1 分钟 5 秒 )纳文： 我来帮你。 ( 1 分钟 11 秒 )访客：你能告诉我什么时候会发生这种情况吗
我希望使用R仅从上面提取相关文本.我基本上只希望访问者评论出现在结果中。
我想要的结果如下：
我发现辉煌的宽带太慢了 我们被告知将是切换的一天 你能告诉我这什么时候会发生吗
我试图使用 gsub 和 strsplit 完成此操作，但无济于事。感谢这里的输入。
mytext <- paste(c("Agent Navin P ( 1s ) Navin: Thanks for contacting XYZ, you are talking to Navin. How can I help? ( 34s ) Visitor:",

保留更多信息的一种可能解决方案：

"Hello , I?ve just currently switched from brillian broadband to fab fibre ( 39s ) Navin: Hi ( 42s ) Navin: Good morning. ( 47s )",

library(dplyr); library(textshape); library(stringi)
mytext %>%

mutate(dialogue = ifelse(!grepl('\(\s*([0-9ms ]+)\s\)', dialogue), paste(dialogue, '( - )'), dialogue)) %>%

## [[1]]

## 2 Navin Thanks for contacting XYZ, you are talking to Navin. How can I help? 34s
## 3 Visitor Hello , I?ve just currently switched from brillian broadband to fab fibre 39s

## 10 Visitor Can you tell me when this will happen by -
然后，您可以按人员等进行过滤。
我相信有很多方法可以做到这一点。我拆分了访客并使用 sub 删除了 Navin 的答案。 对于替换，我们需要在末尾添加[-1]，因为我们在拆分的第一个"访客"之前不需要任何东西。
str <- "Chat Started: Monday, April 02, 2018, 10:23:30 (+0100) Chat Origin: GB - My Account (Signed In) Agent Navin P ( 1s ) Navin: Thanks for contacting XYZ, you are talking to Navin.

str <- strsplit(str," Visitor: ")[[1]]
sub(" \((.*?)\) Navin:.*","",str)[-1]
# [1] "Hello , I?ve just currently switched from brillian broadband to fab fibre"
# [2] "I find the brilliant broadband so slow"
# [3] "And we got told would be a day to get switched over"
# [4] "Can you tell me when this will happen by"
如果你想要像你的例子这样的一行，你可以使用paste
paste(sub(" \((.*?)\) Navin:.*","",str)[-1],collapse = " ")
# [1] "Hello , I?ve just currently switched from brillian broadband to fab fibre I find the brilliant broadband so slow And we got told would be a day to get switched over Can you tell me when this will happen by"
如果此人的姓名不一致为"Navin"，则可以使用\w+匹配sub查询中任何人的姓名以将其删除。
sub(" \((.*?)\) \w+:.*","",str)[-1]
