A Crowdsourced Online Dictionary Of Slang Words And Phrases

December 11, 2014

Following yesterday’s blog post, “KPC – “Keeping Parents Clueless” With Text Messaging“, a visitor to What’s On My PC pointed me in the direction of the Urban Dictionary that you may find to be helpful; and, if anything quite entertaining. Just beware, some definitions may be for your eyes only.

Urban Dictionary

Urban Dictionary is a crowdsourced online dictionary of slang words and phrases that was founded in 1999 as a parody of Dictionary.com by then-college freshman Aaron Peckham. At the start of 2014, the dictionary featured over seven million definitions, while 2,000 new daily entries were being added. In November 2014, the Advertise page of the website states that, on a monthly basis, Urban Dictionary averages 72 million impressions and 18 million unique readers. Anyone with either a Facebook or Gmail account can make a submission to the dictionary, and all entries are reviewed and rated by volunteer editors and site visitors… Source: Wikipedia

An Incredibly Fast Online Dictionary

September 27, 2010

Recently I posted an article about Google’s dictionary (titled: Did you know Google has a dictionary?) that was quite popular. To add to your dictionary collection, I encourage you take a look at another online dictionary, called Definir.


Definr.com is a fast, free dictionary based on Princeton’s open WordNet 2.0.

The website framework is Ruby on Rails. Looking up words in a dictionary is easy, so we do that with MySQL and cache the top 10,000 definitions in memory.

Doing word completion (a.k.a. auto-complete, auto-suggest, globbing) is not easy, at least not when you have to search through 200,000 words for every keystroke. So our word completion is done in a C module for Ruby, and the word completion server is separate from the rest of the site.

With the DefinrBot algorithm, we can do 190,000 word completions per second without caching, and that translates to about 10,000 completions per second once the Ruby layer is factored in.

Definir is available as a Firefox extension or you can drag Definir to your Firefox toolbar, where you can look up words on the fly. I tested the toolbar bookmarklet in Google Chrome, and it worked there, as well.
