A named list holding the parsed corpus object.

Examples

corpus <- list(
  schema_version = "1.0", id = "demo-corpus",
  records = list(
    list(id = "w1", keywords = list("arousal", "threat")),
    list(id = "w2", keywords = list("arousal", "threat"))
  )
)
path <- tempfile(fileext = ".json")
jsonlite::write_json(corpus, path, auto_unbox = TRUE)
tf_read_corpus(path)
