Offshore Holdings Analytics Using Datalog+ RuleML Rules

In April 2013, the International Consortium of Investigative Journalists (ICIJ) exposed the details of 130,000 offshore accounts. Although there are legitimate businesses which use such accounts, there exist a number of accounts which are possibly linked to international tax fraud and money laundering. The ICIJ investigation was based on 2.5 million records of offshore holdings linked to 170 countries. All these records have been made available for further examination and analysis. Based on these records, a set of facts, rules and queries have been formulated in Datalog+ RuleML 1.01/XML and these rules have been tested and validated against the Relax NG schema for Datalog+ in RuleML 1.01/XML. The usefulness of such rules for offshore holdings analytics is demonstrated here via incremental step-by-step approach, through the discovery of relationships between persons hiding large sums of assets and the offshore companies where the assets are purported to be hidden.
