Detection of inappropriate content in social networks

How to extract information from users who publish this content

This gist is an implementation to blogpost that I wrote about relationships between social networks.

link blogger faceboook twitter gplus youtube pinterest

In the example of blog, to extract the information, I use the apis of YouTube, Twitter and Souncloud Api’s and using the method API REST. In this case, I prepare the dataset. We can relate different social networks to extract account information. First, twitter its a continuos feed of publications, we can extract differents elements about a tweet (hasthags, mentions, url). The urls are the elements that link a social network to another , giving us great potential.

Sample data set

Entities

  • Tweets with attribute screen_name,text,timepstamp and country.

  • URL with attribute url.

  • YouTubeVideos with attributes title, channelid, tags, ytAgeRestricted and update.

  • Tracks with attribute title, description and upload.

  • Channels with attribute screen_name, description, googleplusid, relatedvideos and channelcreate.

  • Googleusers with attribute displayName, aboutMe, image, location and gender.
