Fnielsen

Joined 23 August 2002

fnielsen is (me!) Finn Årup Nielsen, Lyngby, Denmark, - an engineer working with data science. I edit in Wikipedia, perform research on wikis and Wikipedia.

My work edit

 
Skallerupvognen. From Nationalmuseet. Taken as part of the collaborative project "Wikipedia Loves Nationalmuseet".

On Wikipedia and sister projects edit

I have been active on the English and Danish versions of Wikipedia, with the first English Wikipedia entry August 23 2002 and the first Danish February 11 2002.

Among the articles I have added to are non-negative matrix factorization, ratio distribution, intraclass correlation, Niels A. Lassen, John Lykoudis and 5-HTTLPR. My English edits have usually been related to my work. On the Danish Wikipedia I usually write articles that are not related to my work. I also take photos for Wikimedia Commons. Most photos have been of Copenhagen and suburbs.

(I have a sandbox as a subpage where I try to understand Wikipedia tables, templates, substitutions, transclusions and other technical details of Wikipedia.)

Community edit

I am a member of Wikimedia Denmark, and presently is a member of the board. I have been at Wikimania in Alexandria, Gdansk and London.

Tools edit

I have made a tool that converts a PubMed/MEDLINE identifier, PMID, to a cite journal template. As of 2008 it is available from [3]

On the Toolserver I had a online visualization service called revvis. Enabled for the Danish Wikipedia, it shows the sequential collaboration network for a Wikipedia article.

The most recent Toolforge tools are Scholia, Wembedder, CVRminer and Ordia.

Research on Wikipedia edit

Article-by-author matrix factorization edit

I participated in WikiSym 2006 in Odense and had a short talk in the workshop about Wikipedia research organized by Jakob Voß and Angela Beesley. The slides used for the presentation are available from the department archive[1]: Non-negative matrix factorization decomposed a article-by-author data matrix for identification of clusters of authors and articles.

Scientific citations in Wikipedia edit

In 2007 I looked at the outbound citations from Wikipedia (using Template:Cite journal) to scientific journals.[2] Nature and Science were the most cited. I compared the number of citations with citation information from Journal Citation Reports of Thomson Scientific, and the correlation between the two sets of values was not bad, e.g., when a scientific journal had many citations it tended to also have many Wikipedia citations. An updated scatter plot for the July 2007 database dump is available [4].

I also tried to cluster scientific journals and Wikipedia articles and made a longitudinal comparison of the citation information. This is described in Clustering of scientific citations in Wikipedia.

The data set used for the clustering is available from the homepage [5] and a couple of researcher have used it to test machine learning algorithms, see the references on Google Scholar.

Wiki for representing and computing with scientific data edit

I am experimenting with representing scientific data in a wiki-like environment. My first attempt was a spreadsheet link online service for personality genetics. It is available from:

http://neuro.imm.dtu.dk/cgi-bin/brede_wiki_personalitygenetics

I now mostly work with the "Brede Wiki".

http://neuro.imm.dtu.dk/wiki/

This MediaWiki-based wiki can represent spreadsheet-like data and meta-analysis is presently performed with an online script.

On Wikimania 2010 I tried to argue for a way to represent scientific data in Wikipedia: Wikipedia is not the sum of all human knowledge. I look forward to see how Wikidata can be used for such data.

Review of Wikipedia research edit

Since 2008 I have been writing a review on Wiki and Wikipedia research entitled Wikipedia research and tools: Review and comments. I now collaborate with fellow researchers (Chitu Okoli and others) on the Internet to summarize and review Wikipedia research. We presently have a long working paper entitled The people's encyclopedia under the gaze of the sages: a systematic review of scholarly research on Wikipedia, see at http://ssrn.com/abstract=2021326 . We maintain the data for the review on a Semantic MediaWiki at http://wikilit.referata.com. The setup of this wiki was inspired by WikiPapers (http://wikipapers.referata.com) at and my Brede Wiki.

I have also written a popular science overview of Wikipedia research in Danish: Wikipedia - nørdernes sejr over vandalerne?.

Blog edit

I maintain blogs where I sometimes write posts relating to Wikipedia. These may be opinionated or related to my work. I was originally writing from Posterous, but as this is closed down Wikipedia posts from my blogs can be found here:
