Collocation of Comments — collocate

This function provides the frequency of collocations in comments that correspond to the provided transcript.

Usage

collocate_comments(transcript_token, note_token, collocate_length = 5)

Arguments

transcript_token: transcript token to act as baseline for notes, resulting from tokenize_source()
note_token: tokenized document of notes, resulting from tokenize_derivative()
collocate_length: the length of the collocation. Default is 5

Value

data frame of the transcript and corresponding note frequency

Details

Collocations are sequences of words present in the source document. For example, the phrase "the blue bird flies" contains one collocation of length 4 ("the blue bird flies"), two collocations of length 3 ("the blue bird" and "blue bird flies"), and three collocations of length 2 ("the blue", "blue bird", and "bird flies"). This function counts the number of corresponding phrases in the 'notes', or the derivative documents. Matches between the two documents must be exact

Examples

# Tokenize the derivative document
toks_comment <- tokenize_derivative(comment_example[1:100,], text_column="Notes")
# Tokenize source document
toks_source <- tokenize_source(transcript_example)
# Compute collocation frequencies
collocation_object <- collocate_comments(toks_source, toks_comment)
