Question

BlackTom AI · Accepted Answer

Examining the question, we need to identify how text data should be formatted in the Tidy format in R when dealing with tokenized text.
Option 1: 'one token per column' — This is not consistent with tidy data principles, which typically structure observations in rows and variables in columns, so placing a token per column would create a column for each token, which is unwieldy and contrary to tidy data conventions.
Option 2: 'one text document per data frame' — In tidy data, each row represents an observation and each column a variable; having a separate text document per data frame would mix data types and break the tidy structure, making analysis less straightforward and not aligned with the expected tokenization approach.
Option 3: 'one token per row' — This aligns with tidy data practices for text data, where each token is a single observation in a row, allowing for consistent row-wise operations, easy counting, and compatible downstream processing in the tidyverse.
In summary, the tidy approach treats each token as an individual observation, which is why the 'one token per row' option correctly reflects the intended format. The other options contradict tidy-data principles by either fragmenting the data into columns per token or by introducing external text documents instead of internal data frame structure.
