Long Tail, Copyright vs Preservation, Diminished Reality, and Augmented Data

  1. Mechanical Turk Requester Activity: The Insignificance of the Long TailFor Wikipedia we have the 1% rule, where 1% of the contributors (this is 0.003% of the users) contribute two thirds of the content. In the Causes application on Facebook, there are 25 million users, but only 1% of them contribute a donation. [...] The lognormal distribution of activity, also shows that requesters increase their participation exponentially over time: They post a few tasks, they get the results. If the results are good, they increase by a percentage the size of the tasks that they post next time. This multiplicative behavior is the basic process that generates the lognormal distribution of activity.
  2. Copyright Destroying Historic Audio — so says the Library of Congress. Were copyright law followed to the letter, little audio preservation would be undertaken. Were the law strictly enforced, it would brand virtually all audio preservation as illegal. Copyright laws related to preservation are neither strictly followed nor strictly enforced. Consequently, some audio preservation is conducted.
  3. Diminished Reality (Ray Kurzweil) — removes objects from video in real time. Great name, “diminished reality”. (via Andy Baio)
  4. Data Enrichment Service — using linked government data to augment text with annotations and links. (via Jo Walsh on Twitter)

    Re: Diminished Reality.
    That is really impressive, with a host of obvious commercial applications.

    Funny — my next Codeboxfor Makezine is on how to diminish reality using Processing and OpenCV. Following a Halloween theme, my application is a bit more gruesome…
