CHAT, FoLiA, PaQu metadata, plaintext and TEI to Alpino XML or PaQu metadata format

Converts CHAT, FoLiA, PaQu metadata, plaintext and TEI XML files to Alpino XML files. Each sentence in the input file is parsed separately.

Usage

Command Line

pip install corpus2alpino
corpus2alpino -s localhost:7001 folia.xml -o alpino.xml

Or from project root:

python -m corpus2alpino -s localhost:7001 folia.xml -o alpino.xml

Library

from corpus2alpino.converter import Converter
from corpus2alpino.annotators.alpino import AlpinoAnnotator
from corpus2alpino.collectors.filesystem import FilesystemCollector
from corpus2alpino.targets.memory import MemoryTarget
from corpus2alpino.writers.lassy import LassyWriter

alpino = AlpinoAnnotator("localhost", 7001)
converter = Converter(FilesystemCollector(["folia.xml"]),
    # Not needed when using the PaQuWriter
    annotators=[alpino],
    # This can also be ConsoleTarget, FilesystemTarget
    target=MemoryTarget(),
    # Set to merge treebanks, also possible to use PaQuWriter
    writer=LassyWriter(True))

# get the Alpino XML output, combined into one treebank XML file
parses = converter.convert()
print(''.join(parses)) # <treebank><alpino_ds ... /></treebank>

Enrichment

It is possible to add custom properties to (existing) Lassy/Alpino files. This is done using a csv-file containing the node attributes and values to look for and the custom properties to assign.

For example:

python -m corpus2alpino tests/example_lassy.xml -e tests/enrichment.csv -of lassy

See corpus2alpino.annotators.enrich_lassy for more information.
