totalngrams

Package for effectively processing token lists from very large corpora in tab separated value format, by making full use of multicore-processors.

An older version of totalngrams was used for Koplenig et al. (2022).

Synopsis

totalngrams [-dhlNSV] [--force] [--pad] [-f=<fold>] [-F=<FOLDS>]
                   [-L=<logFileName>] [-n=<ngram_size>] [-o=<output_fillename>]
                   [-p=<worker_pool_specification>] [-P=<max_threads>]
                   <inputFiles>...
sum ngram counts from KorAP-XML, CoNLL-U files and frequency lists
      <inputFiles>...    input files
  -d, --downcase         Convert all token characters into lower case (default:
                           false)
  -f, --fold=<fold>      current fold (default: 1)
  -F, --folds=<FOLDS>    number of random folds (default: 1)
      --force            Force overwrite (default: false)
  -h, --help             Show this help message and exit.
  -l, --with-lemma-pos   Use also lemma and part-of-speech annotations
                           (default: false
  -L, --log-file=<logFileName>
                         log file name (default: totalngrams.log)
  -n, --ngram-size=<ngram_size>
                         n-gram size (default: 1)
  -N, --numeric-secondary-sort
                         Sort entries with same frequency numerically
                           (default: false)
  -o, --output-file=<output_fillename>
                         Output file (default: -)
  -p, --worker-pool=<worker_pool_specification>
                         Run preprocessing on extern hosts, e.g. '10*local,
                           5*host1,3*smith@host2' (default: )
  -P, --max-procs=<max_threads>
                         Run up to max-procs processes at a time (default: 6)
      --pad              Add padding «START» and «END» symbols at text edges
                           (default: false)
  -S, --sort             Toggle output sorting (default: true)
  -V, --version          Print version information and exit.

Example usage

FOLDS=16
BASE="."

for l in "-l"; do #  "-l"
  for n in $(seq 1 2 3); do
    for f in $(seq 1 $FOLDS); do
      totalngrams\
        --pad \
        -P 79 \
        -n $n \
        -f $f \
        -F $FOLDS \
        $l -o "$BASE/paddedlemmaposfreq/$n-gram-token$l-freqs.$f.tsv.xz" $BASE/conllu/*.conllu.gz
    done
  done
done

Scripts

The package also contains some groovy scripts for handling pseudonymization tasks, i.e. replacing each token or lemma with a corresponding number according to separate key files.

You can run the groovy scripts directly, if you have installed groovy or from the totalngrams jar, otjherwise.

GeneratePseudonymKey

Example usage

./src/main/groovy/org/ids_mannheim/GeneratePseudonymKey.groovy -h

or:

generate_pseudonym_key -c 0 1-gram-token-l-freqs.*.tsv.xz | xz -T0 > token_key.tsv.xz

Pseudonymize

Example usage

pseudonymize -d /tmp -k tokens_key.tsv.xz -k lemma_key.tsv.xz  *-gram-token-l-freqs.*.tsv.xz

FilterKeys

Example usage

filter_keys -k token_keys.tsv.xz -k lemma_keys.tsv.xz 1-gram-token-l-freqs.*.tsv.xz
