維基百科編輯視覺化呈現

[color=#333333][font=Verdana, Arial, Tahoma, Helvetica, sans-serif][size=16px]Wikipedia edits visualized[url=http://infodisiac.com/blog/2011/05/wikipedia-edits-visualized/]Monday May 9, 2011[/url][/size][/font][/color][color=#333333][font=Verdana, Arial, Tahoma, Helvetica, sans-serif][size=16px]
[size=13px]Today I’d like to present to you a [b][url=http://stats.wikimedia.org/wikimedia/animations/requests]new visualization about Wikipedia[/url][/b].[/size]

[size=13px]It shows all edit events for all Wikipedia’s on one random day. Currently this is 14 February 2011. On that particular day all Wikipedia’s combined had been edited 403,659 times.[/size][/size][/font][/color]
[color=#333333][font=Verdana, Arial, Tahoma, Helvetica, sans-serif]
[size=13px]The visualization grabs all those edits (time, location and language code) and shows how these were spread over the globe. You can see the distribution over space and time in an animation. You can also see static maps: bubble maps and heat maps, either per major language or for all languages combined. For bubble maps: large bubbles correspond to many edits, done from the location at the center of the bubble. For heat maps: bright colors correspond to many edits from that particular spot. Bubbles help you quickly focus on areas of large activity, heat maps have better resolution.[/size][/font][/color]
[color=#333333][font=Verdana, Arial, Tahoma, Helvetica, sans-serif]
[size=13px]You can zoom and pan (mouse), click on the map for latitude and longitude (only when zoomed out), change the animation speed (5x-30x), toggle between color and black&white map (latter with country borders), show/hide the position of the sun, city names and approximated local times, and change event marker type and size (types are circle, fixed or animated language code). You can cycle through major languages  (easiest with space bar), fast forward the clock by 1 hour, or pause the animation. Type H for Help on all options and their associated keys.[/size]

[color=#333333][font=Verdana, Arial, Tahoma, Helvetica, sans-serif][size=3]Privacy[/size][size=13px]Two measures were taken to guard privacy of authors. Timestamps have a deliberate error of up to 10 minutes. For very active editors or wiki’s with little activity this would not suffice. More importantly all coordinates have been rounded to a half degree longitude and latitude (roughly 55 km or 34 miles squared).[/size]

[color=#333333][font=Verdana, Arial, Tahoma, Helvetica, sans-serif][size=3]Tech note[/size][size=13px]The animation and maps were implemented in html5, with the canvas object. I used this same approach two years ago,with [b][url=http://stats.wikimedia.org/wikimedia/animations/growth/AnimationProjectsGrowthWp.html]another animation about Wikipedia[/url][/b]. Since then browser support for html5 canvas has considerably improved.[/size]

之前介紹過的「維基百科編輯泡泡」,出新版了。這次可以一次看許多版本一起冒泡。比較的時候要留意時區差異,我點進去播放的時候歐洲的編輯活動最活躍。

看過一輪播放(2/14全天),可以跟先前討論的編輯量表格作對照。
臺灣冒出來的泡泡,突顯了台灣維基人在中文維基百科中流砥柱的重要性,
香港的泡泡跟台灣一樣快,可是有一半的顏色是英文版泡泡,
中國大陸的泡泡冒出來的情況很稀疏,全體加起來約等於台灣冒泡的量。

綜上所述:台灣一直冒泡。香港也是,但有一半是英文泡泡。中國大陸的泡泡較慢、集中在幾個大城,總量約等於一個台灣。
