• vertical file

    A vertical file is a text file where each token (or word) is on a separate line. This format is typically used for text corpora and may contain additional metainformation (annotation). Vertical files are usually created from a prevertical format. The first column contains tokens and structures, the other columns may contain part of speech, lemmas or other positional attributes. An example of a vertical file:
