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).
provisional new structures if necessary.
## 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:
Most of the scripts come from other repositories and python libraries.
Run the set-up script:
```
$ bin/setup.sh
$ scripts/setup.sh
```
## pipeline1.py
## Usage
The pipeline1.py script expects as input a file of Slovene strings,
one string per line. It then runs the [python obeliks
The main script is scripts/process.py. There are several modes (
identified via the -part parameter), depending on whether you want to
run the whole pipeline from start to finish (daring!), or with manual
intervention (of the parse) in between. XML validation is also
provided separately.
### strings_to_parse
The input is a file of Slovene strings (one string per line). The
script runs the [python obeliks
tokeniser](https://pypi.org/project/obeliks/) on the input, tweaks the
conllu output a little, and runs JOS-configured
[classla](https://pypi.org/project/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:
Slovene and converts the output to TEI XML. Example:
```
$ python scripts/pipeline1.py -inlist strings.txt -outtei parsed.xml
$ python scripts/process.py -mode strings_to_parse -infile /tmp/strings.txt -outfile /tmp/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
### parse_to_dictionary
The input should be a TEI XML file (in the same particular format as
the output of strings_to_parse) and an xml file of structure
specifications (the CJVT structures.xml file, supplemented with
temporary new structures, if needed). 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](https://gitea.cjvt.si/ozbolt/luscenje_struktur), 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.
multiple-component dictionary files are merged into one dictionary
file. Example:
Example usage:
```
$ python scripts/process.py -mode parse_to_dictionary -infile /tmp/parsed.xml -outfile /tmp/dictionary.xml -structures /tmp/structures_new.xml
```
### strings_to_dictionary
Combines strings_to_parse in parse_to_dictionary into one call
(whereby you forfeit the chance to fix potential parse errors in
between). Example:
```
$ python scripts/pipeline2.py -intei parsed_corrected.xml -instructures structures.xml -outstructures structures_new.xml -outlexicon dictionary.xml
$ python scripts/process.py -mode strings_to_dictionary -infile /tmp/strings.txt -outfile /tmp/dictionary.xml -structures /tmp/structures_new.xml
```
### all
Same as strings_to_dictionary, but also validates the dictionary and
structures outputs, just in case.
```
$ python scripts/process.py -mode all -infile /tmp/strings.txt -outfile /tmp/dictionary.xml -structures /tmp/structures_new.xml
```
## REST API
The package provides a REST API with endpoints roughly mirroring the
process.py modes. For the calls accepting strings as input, GET calls
are also supported for single-string input. For the calls resulting in
dictionaries, the results include both the dictionary entries and the
structures they use. If processing resulted in temporary new
structures, their number is recorded in @new_structures.
Example curl calls
(assuming you deploy at https://www.example.com/structures/):
```
$ curl https://www.example.com/structures/strings_to_parse?string=velika%20miza
$ curl -X POST -F file=@/tmp/strings.txt https://proc1.cjvt.si/structures/strings_to_parse
$ curl -X POST -F file=@/tmp/parse.xml https://proc1.cjvt.si/structures/parse_to_dictionary
$ curl https://www.example.com/structures/strings_to_dictionary?string=velika%20miza
$ curl -X POST -F file=@/tmp/strings.txt https://proc1.cjvt.si/structures/strings_to_dictionary
```
## Note
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
added to the DDD database. That is normally done via the django
import_structures.py script in the [ddd_core
repository](https://gitea.cjvt.si/ddd/ddd_core), 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.
