Semantic Solutions

Our skills. Relying on technologies.

Cognizone is a company founded in 2015 by a team of IT engineers of many disciplines who work on Computer Science and Information Technology for the last 15 to 25 years.

We help organizations and businesses maximize their unique set of data by providing IT and Data Management services with a focus on Semantic Technologies, Linked (and Open) Data, Metadata, Thesauri and Controlled Vocabulary Management.

Since 2015, we engaged in 15+ projects on Legislative open data, open data in the Labour Market and Semantic Interoperability. We successfully implemented deliverables in big government and industrial projects like CELLAR, EUROVOC, ESCO, EUROPASS2, Legi4LUX and Legi4CH. [more info about our projects in this article]

We want to stay driven by innovation.

The world moves on, technology follows closely and we want to “taste” AI, especially on the implementation level. To this end, we want to further foster its adoption within the company.

We want to grow, in a careful and structured manner and focus even more on strengthening our corporate culture, which we believe is one of the strongest keys to success.

We are so far financially independent and we want to continue being that, not neglecting though potential investors.

How we work

Over the years, we successfully implemented industrial-strength solutions for a wide range of clients – from private companies to public stakeholders.

We use all leading technologies with a particular focus across typescript, angular, spring boot, semantic web and much more to develop the best software.

Every day we stand to build better tools to help your data making meaning and sharing its knowledge while focusing on your return on investment (not your expenses).

And we are proud to assert our reliability, craftsmanship, and good humour.

Gregory De Backer

Program Manager

Gregory is the swiss knife of Cognizone. If provided with good coffee, he will always find the best and cost-efficient approach to fulfil and lead your needs! Get settled in your chair, Greg will figure out what to do!

Gregory De Backer started his career at Cognizone as Project Leaders and Business Analyst and participated actively in its growth.

Today, as program manager and founder, he’s a specialist on qualifications and their implementation within Europe.

He’s deeply involved in the elaboration of the Qualification Metadata Schema which is going to be implemented EU wide.

Gregory also participated in the presentation of the project to 15 Member States (at least that is what he told us but we are pretty sure he only went sightseeing).

We are adventurers, volunteers, music lovers, cooks, tailors, mothers & fathers, and much more…

Sometimes I start to watch one of the Lord Of The Rings movie, extended edition (of course) while I’m on lunch break… and I don’t resume work until the movie is ended.

I experienced several times, apple juice leaking through my nose because of too much laughter.

I was a pro fashion model for 10 years but that… it stays between us of course.

Before joining Cognizone I used to be an adventurer but took an arrow in the knee.

Everybody at Cognizone thinks I’m the funniest member of the team (but I guess Domi would disagree)

I graduated last of my class in Master in Computer Science…
It’s just a living proof that I was lazy as shit.

I have a million hair

I am a self made millionaire, with no money.

One time when I was a kid, I fell into Richard Gere at the opening of his photo exhibition (like BAM-oups-sorry)

Luckily for me, I’m better at coding than at finding funny quotes.

When in the office I eat pastries in the mornings so if you shake my keyboard you might get a croissant.

I’m pro at casually taking naps on my desk. Also that blanket in the closet is mine.

I once dreamt I was eating a cotton candy and when I woke up my pillow was gone.

I start classical dance evening classes.

When I was a child, I always thought that eating fried chicken would give me supernatural energy.

When I was a child, I always thought that eating fried chicken would give me supernatural energy.

I have the enthusiasm of a puppy but the attention span of a goldfish. I encounter a potential hobby or an interesting topic, I obsess over it for two weeks, hear about something new and repeat. Safe to say I’m cursed.

My cat shat on every vinyl LPs my schoolmates offered me on my birthday.
Probably because the night before, end of the 70s, official school party – big event, I had my first getting “totally pissed drunk”, and coming home I shooed him off, quite wildly.

Every time some form of chocolate land on my desk, it disappears within minutes. To this day, experts are still trying to figure out how it happens. The most promising lead is that its made from recycled wood that comes from a ship that disappeared in the Bermuda triangle.

I hate mornings and naming variables.
I would have been a pirate but then engineering stole me…and my super power is that I can make a tank of coffee disappear.

Join the team!

We are looking for passionate and curious people to join us. We value clear communication, creativity, full ownership and responsability.
