danker is a compilation of Bash and Python3 scripts that enables the computation of PageRank on Wikipedia on normal off-the-shelf hardware (e.g., a quad-core CPU, 8 GB of main memory, and 250 GB hard disk storage). The BIGMEM option enables to speed up computation given that enough main memory is available (this depends on the Wikipedia language edition and your hardware configuration). The total size of danker is < 150 lines of code.
- INPUT Wikipedia language edition, e.g. "en" OR "ALL" (for computing PR on the union of all language editions - "bag of links" semantics); optional parameter "BIGMEM".
- PROCESSING danker downloads the needed Wikipedia dump files (https://dumps.wikimedia.org/LANGwiki/latest/), resolves links, redirects, Wikidata Q-ids, produces a link-file and computes PageRank.
- OUTPUT
- LANG-DUMPDATE.links - a link file, the input for PageRank (every line reads from left to right: Q-id left --links to--> Q-id right)
- LANG-DUMPDATE.links.rank - a series of Wikidata Q-ids with their respective PageRank (sorted descending)
-
Compute PageRank on the current dump of English Wikipedia:
./danker.sh en ./danker.sh en BIGMEM
-
Compute PageRank on the union of all language editions:
./danker.sh ALL ./danker.sh ALL BIGMEM # caution, you will need some main memory for that
-
Compute PageRank for each Wikipedia language edition:
for i in `./lib/getLanguages.sh`; do ./danker.sh "$i"; done for i in `./lib/getLanguages.sh`; do ./danker.sh "$i" "BIGMEM"; done
Before danker, I performed a number of experiments with DBpedia "page links" datasets most of which are documented at http://people.aifb.kit.edu/ath/.
