User Profile Linkage Across Multiple Social Platforms

Technology Overview

Increasingly, individuals are using multiple online social networks (OSNs) such as Facebook, Twitter or Instagram to meet their communication and relationship needs. The rise of users using multiple OSNs motivates researchers to study the problem of User Identity Linkage (UIL), which aims to link user accounts from different OSNs that belong to the same person. Tackling the UIL problem is imperative to today's social-data-enabled business intelligence. For example, businesses could better profile the consumers if they have a complete view of his or her attributes and behaviours on multiple OSNs. Or they could improve recommendation systems by integrating data of user accounts from different OSNs that belong to the same user to address the cold-start problem, where the system is unable to draw any inferences about which it has not yet gathered sufficient information on.

We offer an algorithmic framework to match user accounts belonging to the same user across multiple online social networks. Given user data from multiple online social networks, our framework employed several state-of-the-art UIL matching algorithms to perform the user accounts matching automatically. Also included in this framework is a visual analytical tool that allows our application users to (a) locate and inspect the linked user accounts, and (b) evaluate and compare results returned by the different UIL matching algorithms.

Technology Features & Specifications

This technology is built upon our in-house data analytics stack, which integrates open-source distributed data systems (such as ElasticSearch), web development frameworks (such HTML5, Javascript, and Django) and open-source data visualization tools (such as D3.js). We also developed our own proprietary data mining and user identity linkage algorithms to automatically perform the online social platform account matching of the user.

Our platform comes with the algorithm and visualizing tool to perform social media analysis, but we do not provide any form of data. Organizations who wish to use our technology will apply our tool on the social media user data that they have obtained through official channels. The social media data obtained by the organization should also be aligned to the data privacy terms of the social media company and data protection laws of the country.
