Brave New Task: User Account Matching

This document discusses matching user accounts across different social media platforms. It notes that while some users publicly link their accounts, many do not. The task is to identify whether two accounts from different social media streams, like Flickr and Twitter, belong to the same user. This is challenging as profile information is often limited or unavailable. A baseline approach treats all tweets as a document and Flickr content as a query, but results show the task is generally very difficult with most accounts not matching. Factors like overlapping active times and more photos/tweets can improve matching. Future work requires handling data restrictions and non-individual accounts.
