概要：
Analyzing the “LIKE” Activities in Social Media:

As one of popular activities in social media, pressing the LIKE button
toward published contents can be interpreted as an indication of one's
shared interests to the contents or the original posters. Therefore,
such LIKE activities form relationships and networks among people,
raising interesting questions about their unique characteristics and
implications. However, there has been very little research that solely
explored the LIKE information in social media.

To address this lack of understanding, we present our recent study:
(1) an analysis on the LIKE activities, especially focusing on their
structural, influential, and contextual aspects, built from 2.3
billion Likes between 130K posters and 44.6 million photos, in
Instagram; (2) unique characteristics of “teens” in their LIKE
activities in Instagram, indicating the so-called “generation LIKE”;
and (3) a preliminary study on accurately predicting user attributes
using their LIKE activities in Flickr.
