Write to a Neo4J database

e.g. write to neo4j://10.128.202.18:7687:

python -m dblp_crawler -k video -k edge -p l/JiangchuanLiu neo4j --uri neo4j://10.128.202.18:7687

Only crawl the paper after specified year

python -m dblp_crawler -k video -k edge -p l/JiangchuanLiu -y 2016 networkx --dest summary.json

Keywords with two or more words

python -m dblp_crawler -k video -k edge -p l/JiangchuanLiu -k "'super','resolution'" networkx --dest summary.json

Init authors from journal

e.g. init authors from ACM MM (db/conf/mm is the key for ACM MM in dblp: "https://dblp.org/db/conf/mm/index.xml")

python -m dblp_crawler -k video -k edge -j db/conf/mm networkx --dest summary.json

Init authors from journal in some variables

Help

python -m dblp_crawler.filter -h                                                       
usage: __main__.py [-h] -i INPUT -o OUTPUT -f FILTER

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT, --input INPUT

Use internal filter

e.g. drop_old_publications is an internal function that drop publication by year

python -m dblp_crawler.filter -i summary.json -o summary.filter.json -f "lambda summary: drop_old_publications(summary, 2016)"

Use multiple filters

e.g. drop_old_publications is an internal function that drop publication by year

python -m dblp_crawler.filter -i summary.json -o summary.filter.json \
  -f "lambda summary: drop_old_publications(summary, 2016)" \
  -f "lambda summary: drop_nodes_by_publications(summary, 4)" \
  -f "lambda summary: drop_nodes_by_all_publications(summary, 4)"

Use your own filter

e.g. another method to use -f "lambda summary: drop_old_publications(summary, 2016)"

python -m dblp_crawler.filter -i summary.json -o summary.filter.json -f "lambda summary: importlib.import_module('dblp_crawler.filter').drop_old_publications(summary, 2016)"
