Unfolding Data Stories with Cogni.zone

Transforming Data for Better Insights
Cognizone, a semantic technology consulting firm based in Brussels, has spent the last decade transforming complex data into clear, interconnected systems and graphs. Their work allows organizations to maximise the data potential through their better understanding, connecting, and utilisation. As a data-startup innovating with Greek tax authorities they are leveraging semantic technology to streamline public sector processes.
At Stone Soup, we had the pleasure of catching up with Dimitrios Perperidis and the Greek team from Cognizone (CZ) to hear about their latest achievements since joining Stone Soup in 2023.
Data-Startup Innovating with Greek Tax Authorities
Cognizone marked its entry into Greece through a groundbreaking collaboration with the Independent Authority for Public Revenue (IAPR, or AADE). This project harnesses linked open data and semantic web technologies to create a state-of-the-art application ecosystem designed to support IAPR’s legislative and regulatory processes. The system revolutionizes navigation and understanding of Greece’s intricate fiscal and taxation legal framework, setting a new benchmark for clarity and efficiency in legal and regulatory management.

Improving Workforce Mobility with the ESCO Classification
The company works with high-profile clients like the DG-Employment, ETF, European Parliament, EC Publications Office and the governments of Luxembourg and Switzerland. Another one of their important projects is the ESCO classification for the European Union’s DG Employment. This classification standardizes job roles and skills across EU member states, aiming to support greater job mobility across the continent. It’s an essential and innovative tool for harmonizing labour markets, making it easier for workers to move and for employers to find the talent they need.

A Startup That Cannot Fail
Dimitrios explained to us, “If we mess up the data, an entire mission critical platform or EU website could go down.” This highlights the level of responsibility and precision Cognizone delivers—ensuring that the data they manage is not just correct but flawlessly integrated into the larger ecosystem.
In fact, what Cognizone does is unique—not just in Greece but across Europe. There’s no other company in the EU quite like them, especially in the legislative sector where the stakes are so high.
