All About TEDx

TEAM : Chan Kim, JT Huang

Our Goal

TED is a nonprofit devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, and Design. The TED Open Translation Project brings TED Talks beyond the English-speaking world by offering subtitles, interactive transcripts and the ability for any talk to be translated by volunteers worldwide. The project was launched with 300 translations, 40 languages and 200 volunteer translators; now, there are more than 32,000 completed translations from the thousands-strong community. The TEDx program is designed to give communities the opportunity to stimulate dialogue through TED-like experiences at the local level.

Our project wants to encourage people to translate TEDx Talk as well by showing how TEDx Talk videos are translated and spreaded among different languages, places and topics, and comparing the spreading status with TED Talk videos.

The questions we are trying to answer:

  • How are the TEDx videos distributed among different languages and places?
  • How is the spreading status of TEDx videos comparing to that of TED videos?


About Dataset

Since TEDx did not provide any API for people to retrieve video data, we write our own scrapper to crawl various attributes of the TEDx videos. And since all TEDx videos are on YouTube, we also use YouTube API to retrieve more interesting information about the videos.

  • TEDx Website

    • Language
    • Event
    • Country
    • Topic
  • YouTube API

    • Uploaded Timestamp
    • Title
    • Tags
    • Thumbnail
    • Duration
    • Like Count
    • Rating
    • Rating Count
    • View Count

TEDx Web Scrapper

First, we try to get all the type portal links from TEDx home URL.

We try to find out all the links begin with the following strings in the TEDx home URL with Beautiful Soup.

  • Language Pages: '/browse/talks-by-language/', EX:
    • Korean: '/browse/talks-by-language/korean'
    • Chinese: '/browse/talks-by-language/chinese'
  • Event Pages: '/browse/talks-by-event/', EX:
    • TEDxBerkeley: '/browse/talks-by-event/tedxberkeley'
    • TEDxStanford: '/browse/talks-by-event/tedxstanford'
  • Country Pages: '/browse/talks-by-country/'
    • South Korea: '/browse/talks-by-country/korea'
    • Taiwan: '/browse/talks-by-country/taiwan'
  • Topic Pages: '/browse/talks-by-topic/
    • Technology: '/browse/talks-by-topic/technology'
    • Design: '/browse/talks-by-topic/design'

Then we go to each type portal link to get video links, and the type will become the attribute of the video.

We will go through page 1, page 2, until there is no other pages in that type attribute. For example, we will go to '', then '' and stop at ''' to get all the 28 videos in Icelandic.

In '' we can find the video link '/list/search%3Atag%3A%22icelandic%22/video/TEDxReykjavik-Eythor-Edvardsson' by using Beautiful Soup and the regular expression. For example, the second video in ''

<a id="mvp_grid_panel_img_1" href="/list/search%3Atag%3A%22icelandic%22/video/TEDxReykjavik-Eythor-Edvardsson" class="mvp_thumbnail_magnified" style="position: relative; width: 293px; height: 220px; background-image: url(''); filter: progid:DXImageTransform.Microsoft.AlphaImageLoader( src='', sizingMethod='scale');" title="TEDxReykjavik - Eythor Edvardsson -"></a>

Stage 3: Get the YouTube ID of the Video

Since all TEDx videos are on YouTube, and we also use YouTube API to get other interesting information of the videos, we use YouTube ID as the key to represent the video. And because Beautiful Soup does not parse through the tag <embed> so we just use the regualr expression to get the YouTube ID.

For example, in the video '' we can find its YouTube ID: 'bzF4GPguPL8'

<embed type="application/x-shockwave-flash" src=";rel=0&amp;fs=1&amp;showsearch=0&amp;enablejsapi=1&amp;modestbranding=1&amp;autoplay=1&amp;playerapiid=mvp_swfo_embed_V8C4K631YLWW0QF3_1299136773" width="634" height="382" style="undefined" id="mvp_swfo_embed_V8C4K631YLWW0QF3_1299136773" name="mvp_swfo_embed_V8C4K631YLWW0QF3_1299136773" quality="high" allowfullscreen="true" allowscriptaccess="always" wmode="opaque" loop="false">
