Tidy emoji tokens, one row per occurrence with metadata

emoji_tokens() expands data to one row per emoji occurrence (in reading order), keeping the original columns and adding the glyph together with its name, category and sentiment score. This mirrors the one-token-per-row shape familiar from tidy text mining and is convenient for counting, joining and plotting.

Usage

emoji_tokens(data, text)

Arguments

data

A data frame or tibble containing a text column.

text

The text column to scan, supplied unquoted.

Value

A tibble with the original columns plus .emoji, .emoji_name, .emoji_category and .emoji_sentiment. Rows without emoji are dropped.

See also

emoji_frequency() for corpus-level counts and emoji_sentiment() for per-row sentiment.

Examples

df <- data.frame(id = 1:2, text = c("great \U0001f600", "bad \U0001f621"))
emoji_tokens(df, text)
