korapxmltool

Tool package to convert and annotate KorAP-XML ZIP files.

Up to 200 times faster and more accurate drop-in replacement for the korapxml2conllu part of KorAP-XML-CoNLL-U.

For some conversion tasks, however, you currently need the conllu2korapxml part of KorAP-XML-CoNLL-U.

Download

You can download the latest jar build from the build artifacts here.

Build it yourself

./gradlew shadowJar

Conversion to a NOW corpus format variant (example)

One text per line with <p> as sentence delimiter.

java -jar korapxmltool.jar -f now /vol/corpora/DeReKo/current/KorAP/zip/*24.zip | pv > dach24.txt

Using lemmas instead of surface forms in word2vec / NOW output

If lemma annotations (morpho layer) are present alongside the base tokens, you can output lemmas instead of surface tokens with --lemma.

# Word2Vec style output with lemmas where available
java -jar ./app/build/libs/korapxmltool.jar --lemma -f w2v app/src/test/resources/goe.tree_tagger.zip | head -3

# NOW corpus style output with lemmas
java -jar ./app/build/libs/korapxmltool.jar --lemma -f now app/src/test/resources/goe.tree_tagger.zip | head -1

If a lemma for a token is missing (_) the surface form is used as fallback.

Lemma-only mode and I/O scheduling

• --lemma-only: For -f w2v and -f now, skip loading data.xml and output only lemmas from morpho.xml. This reduces memory and speeds up throughput.
• --sequential: Process entries inside each zip sequentially (zips can still run in parallel). Recommended for w2v/now to keep locality and lower memory.
• --zip-parallelism N: Limit how many zips are processed concurrently (defaults to --threads). Helps avoid disk thrash and native inflater pressure.
• --exclude-zip-glob GLOB (repeatable): Skip zip basenames that match the glob (e.g., --exclude-zip-glob 'w?d24.tree_tagger.zip').

Example for large NOW export with progress and exclusions:

java -Xmx64G -XX:+UseG1GC -Djdk.util.zip.disableMemoryMapping=true -Djdk.util.zip.reuseInflater=true \
     -jar korapxmltool.jar -l info --threads 100 --zip-parallelism 8 \
     --lemma-only --sequential -f now \
     --exclude-zip-glob 'w?d24.tree_tagger.zip' \
     /vol/corpora/DeReKo/current/KorAP/zip/*24.tree_tagger.zip | pv > dach2024.lemma.txt

At INFO level the tool logs:

• The zip processing order with file sizes (largest-first in --lemma-only).
• For each zip: start message including its size and a completion line with cumulative progress, ETA and average MB/s.

Annotation

Tagging with integrated MarMoT POS tagger directly to a new KorAP-XML ZIP file

You need to download the pre-trained MarMoT models from the MarMoT models repository.

java -jar ./app/build/libs/korapxmltool.jar -f zip -t marmot:models/de.marmot app/src/test/resources/goe.zip

Tagging with integrated OpenNLP POS tagger directly to a new KorAP-XML ZIP file

You need to download the pre-trained OpenNLP models from the OpenNLP model download page or older models from the legacy OpenNLP models archive.

java -jar ./app/build/libs/korapxmltool.jar -f zip -t opennlp:/usr/local/kl/korap/Ingestion/lib/models/opennlp/de-pos-maxent.bin /tmp/zca24.zip

Tag and lemmatize with TreeTagger

This requires the TreeTagger Docker Image with CoNLL-U Support. Language models are downloaded automatically.

java  -jar app/build/libs/korapxmltool.jar app/src/test/resources/wdf19.zip | docker run --rm -i korap/conllu2treetagger -l french | conllu2korapxml

Tag and lemmatize with spaCy

This requires the spaCy Docker Image with CoNLL-U Support and is only available for German.

java  -jar app/build/libs/korapxmltool.jar app/src/test/resources/goe.zip | docker run --rm -i korap/conllu2spacy | conllu2korapxml > goe.spacy.zip

Parsing

Using the integrated Maltparser

You need to download the pre-trained MaltParser models from the MaltParser model repository. Note that parsers take POS tagged input.

java -jar ./app/build/libs/korapxmltool.jar -f zip -T2 -P malt:libs/german.mco goe.tree_tagger.zip
