We presented the project at a Vaticle webinar

The Pandora Papers consist of 11.9 million documents leaked from 14 financial service providers and obtained by the International Consortium of Investigative Journalists (ICIJ). The first stories based on the leaks appeared in print on 3 October 2021, with relevations about the secretive and often questionable financial dealings of heads of state, oligarchs, celebrities, local straw men and the accountants and lawyers providing offshore services.

A processed text version of the leaked documents, combined with data from earlier troves of leaks (Offshore Leaks, Bahama Papers, Panama Papers, Paradise Papers), were made available by the ICIJ as a single dataset - the Offshore Leaks - in early December 2021. The text files consist of tables of entities, officers, intermediaries and other types, and pairwise relationships between them.

Here, we clean and reformat the tabular data, create a simple schema, and import the whole dataset into TypeDB.

Porting the dataset into TypeDB gives us some advantages over traditional property graphs, such as

1. Type inference: a simple Type hierarchy makes it possible to query for an abstract type, such as corporate entity or directed relation, and match all subtypes.
2. Rule inference: TypeDB rules allow us to derive inferred facts automatically when querying.

For example, the schema provided here includes the rule same_date_stop_rule, which infers a possible relationship between legal entities closed on the same date - leveraging both Type inference (matching all types of stopping events) and Rule inference (inferring new facts).

Prerequisites:

• wget or curl
• sed
• Python >3.6
• R 3.6
• TypeDB Core 2.6.x
• TypeDB Python Client 2.6.x
• 16GB RAM

git clone https://github.com/typedb-osi/typedb-data-offshoreleaks.git && cd typedb-data-offshoreleaks

bash ./preprocess.sh

in a separate terminal, start TypeDB

# let java use up to 16GB of memory
JAVAOPTS="-Xmx16G" typedb server

Back in the original terminal, set up the Python environment

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Run the migrator.py script to import the data into TypeDB

# run the migrator with 4 separate processes
python3 ./migrator.py -n 4

For options:

python3 ./migrator.py -h

To query the database, either use TypeDB console or download a graphical user interface (GUI).

A free GUI is TypeDB Studio.

Nodelab, the GUI used for the examples above, has advanced presentation and query features, and will be available shortly (contact Jon Thompson for information)
