Dependencies:
sudo apt install poppler-utils
pip install requests python-magic
Context:
export TODAY="`TZ=UTC date --iso-8601=date`"
export CORDDATE="2020-04-03"
Fetch and transform CORD-19 metadata:
mkdir -p metadata fulltext_web
wget https://archive.org/download/s2-cord19-dataset/cord19.$CORDDATE.csv -O metadata/cord19.$CORDDATE.csv metadata
./covid19_tool.py parse-cord19 metadata/cord19.$CORDDATE.csv > metadata/cord19.$CORDDATE.json
cat metadata/cord19.$CORDDATE.json | parallel -j10 --linebuffer --round-robin --pipe ./covid19_tool.py enrich-fatcat - | pv -l > metadata/cord19.$CORDDATE.enrich.json
cat metadata/cord19.$CORDDATE.enrich.json | jq 'select(.release_id == null) | .cord19_paper' -c > metadata/cord19.$CORDDATE.missing.json
Fetch fatcat query metadata:
./covid19_tool.py query-fatcat | pv -l > metadata/fatcat_hits.$TODAY.enrich.json
Combine and de-dupe:
cat metadata/fatcat_hits.$TODAY.enrich.json metadata/cord19.$CORDDATE.enrich.json | ./covid19_tool.py dedupe | pv -l > metadata/combined.$TODAY.enrich.json
Download fulltext from wayback:
cat metadata/combined.$TODAY.enrich.json | jq .fatcat_release -c | parallel -j20 --linebuffer --round-robin --pipe ./bin/deliver_file2disk.py --disk-dir fulltext_web - | pv -l > fatcat_web_$TODAY.log
cut -f1 fatcat_web_$TODAY.log | sort | uniq -c | sort -nr
Update PDF derivative files (pdftotext and PNG thumbnail):
./bin/make_dir_derivatives.sh fulltext_web
Fetch GROBID:
# TODO
Convert GROBID XML to JSON:
ls fulltext_web/pdf/ | parallel mkdir -p fulltext_web/grobid/{}
fd -I .xml fulltext_web/grobid/ | cut -c18-60 | parallel -j10 "bin/grobid2json.py fulltext_web/grobid/{}.xml > fulltext_web/grobid/{}.json"
Create large derivatives file (including extracted fulltext):
./covid19_tool.py enrich-derivatives metadata/combined.$TODAY.enrich.json --base-dir fulltext_web/ | pv -l > metadata/combined.$TODAY.fulltext.json
cat metadata/combined.$TODAY.fulltext.json | jq .fulltext_status -r | sort | uniq -c | sort -nr
## ES Indices
Create fulltext index, transform to ES schema and index:
# if existing, first: http delete :9200/covid19_fatcat_fulltext
http put :9200/covid19_fatcat_fulltext < schema/fulltext_schema.v00.json
# in fatcat_covid19, pipenv shell
./covid19_tool.py transform-es metadata/combined.$TODAY.fulltext.json | pv -l | esbulk -verbose -size 1000 -id fatcat_ident -w 8 -index covid19_fatcat_fulltext -type release
Create and index existing `fatcat_release` schema:
http put :9200/covid19_fatcat_release < schema/release_schema_v03b.json
# in fatcat python directory, pipenv shell
export LC_ALL=C.UTF-8
cat /srv/fatcat_covid19/src/metadata/combined.$TODAY.enrich.json | jq .fatcat_release -c | rg -v '^null$' | pv -l | ./fatcat_transform.py elasticsearch-releases - - | esbulk -verbose -size 1000 -id ident -w 8 -index covid19_fatcat_release -type release
## GROBID Processing
zip -r fulltext_web.zip fulltext_web
# on GROBID worker, in sandcrawler repo and pipenv
./grobid_tool.py --grobid-host http://localhost:8070 -j 24 extract-zipfile /srv/sandcrawler/tasks/fulltext_web.zip | pv -l > /srv/sandcrawler/tasks/fulltext_web.grobid.json
