我正在做一个使用R进行情感分析的项目。我正在尝试收集使用某些最受欢迎的表情符号的推文。如何通过表情符号收集推文？
#devtools::install_github("dill/emoGG")
library(emoGG) # source of the "emoji_search" function
library(twitteR) # source of the "searchTwitter" and "twListToDF" functions
emoji_search("BALLOON")
emoji <- searchTwitter("BALLOON")
emoji
emojidf <- twListToDF(emoji)
答案 0 :(得分：0)
经过一番谷歌搜索和实验，我了解了emojis are encoded in tweets in a confusing way（至少对我来说）。
一种快捷方式是使用Kate Lyons' here之类的表情符号字典来搜索表情符号。 Some more background about how she compiled it。
这为我们提供了一种更直接的方式来搜索带有表情符号的推文。例如，字典显示如果我们寻找以下字符串，我们可以寻找“ balloon”表情符号：
<ed><a0><bc><ed><be><88>
我对rtweet较为熟悉，这是气球状表情符号搜索的外观：
[编辑：我不确定这是否正常工作。这些看起来都是非英语的推文，并且其中可能没有气球表情符号...] :-(
> rtweet::search_tweets("<ed><a0><bc><ed><be><88>")
