Who added DOI Links to Wikipedia? by Jiro Kikkawa (@jir_o) #WikiCite / WikiCite2018

Hi, Again! WikiCite.
This is Lightning Talk slides to introduce about my ongoing project.
I note that perhaps another version on Dropbox is better (* Contents are absolutely the same, but hyperlinks in slides are also available! ) : https://www.dropbox.com/s/5yi1qczeqojqwcc/wikicite2018.pdf?dl=0

2. Hi, Again! WikiCite • Last year, I talked about “DOI Links on English, Japanese, and Chinese Wikipedias” 2 Slide: https://speakerdeck.com/corgies/wikicite2017 Paper: http://hdl.handle.net/2241/00144576 • Research interest: scholarly references on Wikipedia(s)
3. Who added DOI Links to Wikipedia? • My on-going project (as a Ph.D. study) • Building the Dataset that contains – identified “Who” added DOI Links to the pages on English Wikipedia (as of 5, March 2017), and “When” – also identfied “research fields” for each of them by using Crossref metadata, ISSN, and Essential Science Indicators (Journal Categories) • Q. Who are the Top Editors for each Research Field? 3

8. Q. He or She is Bot? 8 User:Rjwilmsi - Wikipedia https://en.wikipedia.org/wiki/User:Rjwilmsi A. No (but really?)
9. Findings As for User, • 34,072 Editors added 628,288 DOI Links* to English Wikipedia as of 5, March 2017 • Top 3 Editors (All Fields) are Rjwilmsi, Boghog, and Chris Cappocia • Rjwilmsi is the Top Editor in 20 out of 22 Research Fields ! 9 * ( Strictly, it is not ALL DOI Links referenced on English Wikipedia but DOI Links whose Research Fields are identifiable by using ISSN and ESI journal category data )
10. Thank you for your attention J • These results are just one part of my findings Now I’m writing an original paper (in Japanese) by using this dataset. I’d like to share full results at WikiCite Next time! • I will share the dataset, codes, and papers with all of you ASAP (after accepted/published the paper) I hope it will lead to future collaborations among the WikiCite community devoting for similar/related projects, and scientometrics researchers. • If you are the editor I mentioned in this talk, Please raise your hand or talk to me ...

13. Dataset Sample (JSON) Cont. 13 "issn": ["10959203", "00368075"], "doi_created_date": "2004-06-10 19:53:06 UTC", "comment": "made more precise citations; 4 wikilinks", "parsedcomment": "made more precise citations; 4 wikilinks", "yearlag_issued": "9", "yearlag_doi_created": "9", "matched_type": "issn", "full_title": "SCIENCE", "research_field": ["Multidisciplinary"], "bot_flag": false }
14. Note: How to extract DOI Links 1. Download Dump data files from https://dumps.wikimedia.org/backup-index.html 1. externallinks.sql 2. iwlinks.sql 3. pages.sql 2. Import to MySQL 14
15. Note: How to extract DOI Links and identify the page ids 3. Extraction conditions - external links contained “doi.org” in the el_to column of externallinks.sql (it is also needed to remove non-DOI links) - the prefix of interwiki links equaled to “doi” in the iwl_prefix column of iwlinks.sql - INNER JOIN (to filter main namespace: pages.sql) - These process also allow to identify the page ids 15
16. Note: How to identify when the DOI Links were added to the pages 4. Get all revisions for each page contains DOI Links - API:Revisions https://www.mediawiki.org/wiki/API:Revisions 5. Get all hyperlinks referenced on the each revisions - API:parsing_wikitext https://www.mediawiki.org/wiki/API:Parsing_wikitext - I used DOI names (regexp like 10.d+¥/.*?$) as the key and identified the oldest version of the each page that someone added first DOI links to the page - That’s all (I needed a few months to process all of them) 16
17. Note: How to identify “research field” for each DOI Link 1. Get metadata for each DOI names by using Crossref REST API http://api.crossref.org 2. Get ESI journal category data from http://ipscience- help.thomsonreuters.com/incitesLiveESI/8289-TRS.html 1. I converted journal category data like this {Key: ISSN, Value: [Research Fields]} 3. Identify the research field(s) for each DOI link by using ISSN 17
