Description
The shallow syntactic function labeller takes a string in Apertium stream format, parses it into a sequence of morphological tags and gives it to a classifier. The classifier is a simple RNN model trained on prepared datasets which were made from parsed syntax-labelled corpora (mostly UD-treebanks). The classifier analyzes the given sequence of morphological tags, gives a sequence of labels as an output and the labeller applies these labels to the original string.
Labeller in the pipeline
In sme-nob the labeller runs between sme-nob-disam and sme-nob-pretransfer, like an original syntax module.
... | cg-proc 'sme-nob.mor.rlx.bin' | python 'sme-nob-labeller.py' | apertium-pretransfer | lt-proc -b 'sme-nob.autobil.bin' | ...
In other language pairs it may run between morphological analyzer and pretransfer.
Prerequisites
1. Python libraries:
- DyNet (installation instructions can be found here: http://dynet.readthedocs.io/en/latest/python.html)
- Streamparser (https://github.com/goavki/streamparser)
2. Precompiled language pairs which support the labeller (sme-nob)
Installation
Currently only the test version for sme-nob pair is available.
git clone https://github.com/deltamachine/sme-nob_testpack.git cd sme-nob_testpack
Script install_labeller.py adds all the needed files in apertium-sme-nob directory and changes all files with modes.
Arguments:
- apertium_path: path to your apertium-sme-nob directory
- python_path: path to current Python interpreteur (NB: if you just type "python" instead of full path, some dependencies might not work)
- work_mode: -install for installing the labeller and changing modes, -change for just changing modes.
- type_of_change: -lb for using the labeller in the pipeline, -cg for using the original syntax module (sme-nob.syn.rlx.bin) in the pipeline.
For example, this script will install the labeller and add it to the pipeline:
python install_labeller.py /home/user/apertium/apertium-sme-nob /home/user/anaconda3/bin/python -install -lb
And this script will backward modes changes:
python install_labeller.py /home/user/apertium/apertium-sme-nob /home/user/anaconda3/bin/python -change -cg
To do
Add an ability to handle more than one sentence.- Do more tests. MORE.
- Write docstrings and refactore the main code.
- Take the trash out of the github repository before the final evaluation.
- Continue improving the perfomance of the models.
