Prototype
Web Crawler
All company names and URLs are anonymised.
Goods are traded on the web, and thus, we . For example, web data can help to identify vendors of potentially illicit products by their online offers and gathers and enriches data about the online presence of said vendors.
The goal of ATTENTION!'s Web Crawler is to using their online offers as well as to gather web data on these actors since several red flags and patterns of illicit trades require information not present in company databases.
This includes offered by the vendor (brands, product descriptions, prices, images), such as the (claimed) company location, and behavioral / relational data such as where potentially illicit vendors advertise or which websites are linking to theirs.
Data Model & Red Flags
Company Networks
All company names, addresses and person names are anonymised. This demonstration is based on an early version of our prototype.
To , it is relevant to understand company networks and to investigate entities that could be behind complex trade-based money laundering structures.
describes companies, their attributes (e.g., revenue and address) and relations (e.g., subsidiaries).
Trade Data
Trade data is about (example of a trade transaction: a good of category "Furniture" that is delivered from Hamburg to Singapore on May 6, 2023), and it is relevant to .
By connecting trade data with vessel positions, we aim at the detection of in global trade.
Key Results
- together with extensive and metadata
- models to understand and detect patterns of illicit trade activity
- MVP that
