Text Interchange Formats (TIF)

The Text Interchange Formats (TIF) is a set of standards that allows R text analysis packages to target defined inputs and outputs for corpora, tokens, and document-term matrices.

Valid data.frame of tokens

The data.frame of tokens here is a data.frame object compatible with the TIF.

A TIF valid data.frame of tokens are expected to have one unique key column (named doc_id) of each text and several feature columns of each tokens. The feature columns must contain at least token itself.
