Wikipedia users session duration?
by Stella Yu 22 Aug '13

22 Aug '13

We are aware that Wikipedia does not track user sessions. There may be survey/poll companies that have surveyed people about their usage and their time spent on Wikipedia. Curious, where are there reports that can shed some light on this? Thank you! All the best, Stella --

Java-based Wiktionary Library (JWKTL) 1.0.0 released as open source software
by Judith Eckle-Kohler 20 Aug '13

20 Aug '13

[Apologies for X-posting] We are pleased to announce the release of the Java-based Wiktionary Library (JWKTL) 1.0.0 - an application programming interface for Wiktionary. Project homepage: http://code.google.com/p/jwktl/ == Overview == JWKTL (Java-based Wiktionary Library) is an application programming interface for the free multilingual online dictionary Wiktionary (http://www.wiktionary.org). JWKTL enables efficient and structured access to the information encoded in the English, the German, and the Russian Wiktionary language editions, including sense definitions, part of speech tags, etymology, example sentences, translations, semantic relations, and many other lexical information types. The Russian JWKTL parser is based on Wikokit (http://code.google.com/p/wikokit/). Prior to being available as open source software, JWKTL has been a research project at the Ubiquitous Knowledge Processing (UKP) Lab of the Technische Universität Darmstadt, Germany. The following people have mainly contributed to this project: Yevgen Chebotar, Iryna Gurevych, Christian M. Meyer, Christof Müller, Lizhen Qu, Torsten Zesch. == Publications == A detailed description of Wiktionary and JWKTL is available in our scientific articles: * Christian M. Meyer and Iryna Gurevych: Wiktionary: A new rival for expert-built lexicons? Exploring the possibilities of collaborative lexicography, Chapter 13 in S. Granger & M.

generating reports of visitor traffic + edit activity in a single report by theme?
by Stella Yu 16 Aug '13

16 Aug '13

Greetings, I am curious about generating reports about editing activity against pageviews on articles linked from a particular trending article. The hypothesis is that editing activity does not receive proportional increases to pageviews. For example, on July 6, 2013 Asiana Airlines Flight 214 crashed at San Francisco International Airport. In the weeks following the event, there was an increase of visitor traffic on articles such as aviation safety, black box (transportation), and cockpit voice recorder, and flight recorder. Empirical evidence shows that edit activity was low on those articles. Perhaps it’s because there was a lot of activity on the Asiana Airlines Flight 214 article? Does anyone know of any preexisting tools to generate these types of reports? I know it could be custom-made, but wanted to see if there was already any work done first. Stella

Survey for Wikinews original reporters
by Laura Hale 14 Aug '13

14 Aug '13

Hi, If you are a Wikinews reporter in any language who has done original reporting any time in the past two years, we would like you to complete a survey at https://docs.google.com/forms/d/1kvLJYT8tKFmOoK-7mb8yWDc9yojT8b2nEElgwepCQh… the costs of doing original reporting. Even if you have done original reporting and spent no money directly, we would like you to report this. This research is being done by people affiliated with The Wikinewsie Group ( http://meta.wikimedia.org/wiki/The_Wikinewsie_Group ) to assess the level of current funding going into Wikinews original reporting, who is paying for it and what the outcomes for the money spent are. We hope to be able to use this information to better assist reporters in doing original reporting, finding funding through external grants to support it, and to better understand the inherent value in original news reporting. To original reporters, thank you for taking the time to answer the survey. If you have question about the research, please get in touch with me and I will be happy to discuss it. Sincerely, Laura Hale -- twitter: purplepopple blog: ozziesport.com

Re: [Wiki-research-l] Readable characters vs. size in bytes of articles
by Floeck, Fabian (AIFB) 07 Aug '13

07 Aug '13

Ok, I don't want to spam, but... I just finished downloading another random sample of 5000 articles with sizes of 5000 bytes and below (this time not excluding disambiguation articles, as the respective DB query is quite slow...) . For these, the correlation is 0.514. Plot [1] This seems to be in favor my observation from earlier that the smaller articles in byte size *might* show a weaker correlation. Very interesting topic, too bad I have to get back to project work now.. :) Best, Fabian [1] https://dl.dropboxusercontent.com/u/3021002/scatter_random5000_UNDER5001byt… ________________________________________ From: Giovanni Luca Ciampaglia [glciampagl(a)gmail.com] Sent: Wednesday, August 07, 2013 3:55 PM To: Floeck, Fabian (AIFB) Subject: Re: [Wiki-research-l] Readable characters vs. size in bytes of articles Hi Fabian, in principle you should be able to recover the same correlation also in the range 5800-6000 Kb, provided that you control for the noise in the data. From your scatterplot it looks like that the variance of the residuals is constant (a scatter plot of the residuals should be enough to confirm this), so if you standardize the residuals by the standard deviation of the residuals you should be able to recover the correlation, though the significance of such estimate might be at risk if the sample size is small.

Re: [Wiki-research-l] Readable characters vs. size in bytes of articles
by Floeck, Fabian (AIFB) 07 Aug '13

07 Aug '13

Hi Giovanni, thanks, good you mention that. But one question: did you by chance mistake the scatter plot I posted in my last mail (from the random 5000 article sample, corr: 0.96) for the one of the 5800-6000 byte sample (corr: 0.04)? Because the ladder was not posted yet and one looks like this: [1] or in a cut-off version at ~20000 chars like this: [2]. By the way: I split up the random 5000 article sample I posted last time at the median (3709 bytes) into two parts, each 2500 articles big. For the "higher byte size" part (>3709 bytes) the correlation is 0,964 For the "lesser byte size" part (<3710 bytes ) the correlation only 0,295 See plots [3] --> It seems from that sample as if the bigger articles seem to exhibit a higher correlation than the smaller ones. I also plotted the residuals, they "kind of" show homogeneity of variance, although I would have to check that with a test. See [4] All in all I feel that the question "How far and when can we rely on byte size to tell us the actual display character length of an article?" can maybe be better be answered when we look at the distribution of the ratio of bytes to display chars in different byte size segments. I'll try to look into that or encourage someone else to do it.
