如何从感伤者词典中删除多个术语？

例如，“请”和“建议”这两个词与积极情绪相关联，但我不希望这些特定词影响我的分析。

我已经想出一种方法，使用以下脚本排除 1 个单词，但需要排除更多：

mysentiment<- lexicon::hash_sentiment_jockers_rinker[x != "please"]

mytext <- c(
  'Hello, We are looking to purchase this material for a part we will be making, but your site doesnt state that this is RoHS complaint. Is it possible that its just not listed as such online, but it actually is RoHS complaint? Please advise. '
)

sentiment_by(mytext, polarity_dt = mysentiment)
extract_sentiment_terms(mytext,polarity_dt = mysentiment)

【解决方案1】：

您可以子集 mysentiment data.table。只需创建一个您不希望包含的单词的向量并将其用于子集。

mysentiment<- lexicon::hash_sentiment_jockers_rinker
words_to_exclude <- c("please", "advise")
mysentiment <- mysentiment [!x %in% words_to_exclude]
