This document proposes a system called WISE (Wider Internet Semantic Enrichment) to link online user identities and enrich profile data. WISE retrieves publicly available information from internet sources using an email address. It matches and consolidates a user's contacts, demographics, social profiles, organization details, and photos. WISE was tested on a list of Italian email addresses and achieved a 28% match rate across these different identity profile fields. The goal of WISE is to generate business-relevant user information by linking a user's multiple online identities indicated by their email address.
