Structure assignment pipeline

Pipeline for parsing a list of arbitrary Slovene strings and assigning each to a syntactic structure in the DDD database, generating provisional new structures if necessary. The pipeline consists of two separate wrapper python3 scripts, pipeline1.py and pipeline2.py, in order to facilitate manual corrections of the parsed units in between (e.g., with qcat).

Setup

The scripts are mostly wrappers, in that they largely use generic scripts and resources from other git repositories, as well as python libraries. These can be set up with a special script:

$ bin/setup.sh

pipeline1.py

The pipeline1.py script expects as input a file of Slovene strings, one string per line. It then runs the python obeliks tokeniser on the input, tweaks the conllu output a little, and runs JOS-configured classla to parse the output. It then translates the JOS tags (msds and dependencies) from English to Slovene and converts the output to TEI XML.

Example usage:

$ python scripts/pipeline1.py -inlist strings.txt -outtei parsed.xml

pipeline2.py

The pipeline2.py script expects as input a TEI XML file (in the same particular format as the output of pipeline1.py) and an xml file of structure specifications (normally the up-to-date CJVT structures.xml file). It first splits the TEI file into two files, one with the single-component units and the other with the multiple-component units. For each, it then assigns each unit to a syntactic structure from the DDD database and converts the output into CJVT dictionary XML format. For the single-component units, this is pretty trivial, but for multiple-component units it is more involved, and includes two runs of the MWE extraction script wani.py, generating missing structures in between. At the end, the single-component and multiple-component dictionary files are merged. Both the merged dictionary file and the updated structure specification file are validated with the appropriate XML schemas.

Example usage:

$ python scripts/pipeline2.py -intei parsed_corrected.xml -instructures structures.xml -outstructures structures_new.xml -outlexicon dictionary.xml

Note that any new structures generated are given temporary ids (@tempId), because they only get real ids once they are approved and added to the DDD database. That can be done via the django import_structures.py script in the ddd_core repository, normally as part of a batch of DDD updates. That script replaces the temporary ids in the structure specifications and updates the ids in the dictionary file.
