Where things stood
Eventim, one of Europe’s leading ticketing platforms, takes in hundreds of new events a day — concerts, sport, theatre, exhibitions and festivals — from promoters, organizers and feeds that each use their own labels, formats and category structures. Manual tagging and a static taxonomy could not keep up with new genres, formats and artists, and the same artist often appeared under different names across local systems, mixed in with venues and other non-artist records.
What changed
Claro keeps a taxonomy that updates from the live inventory and from what people search for, classifies each new event into its category and subcategory, and enriches it with attributes such as genre, artist type, venue characteristics, language, region and format. Artist records are resolved into one global identity, with confidence and matching evidence attached. Uncertain classifications and matches go to an internal review interface, where Eventim’s content and marketing teams correct predictions and propose new categories.
What it looks like today
New events are categorized and enriched automatically, instead of tagged by hand before they are listed.
Category and landing pages follow real search demand, because the taxonomy changes as inventory and searches change.
One identity per artist across local systems, with uncertain matches held for review rather than merged silently.
For a catalog that changes every day, the taxonomy has to change with it: continuous classification with human review, not a one-off mapping.
