Case Study: ImmobilienScout24 achieves accurate, scalable online property appraisals by unlocking 90%+ of unstructured listings with InterSystems

Intelligent automatic data analysis for millions of documents

ImmobilienScout24 is Germany’s largest real‑estate portal, serving over 10 million monthly users and holding more than 180 million listings. Its online valuation tool requires structured property attributes and at least ten comparable objects, but much critical information was buried in unstructured listing text, leaving many properties unusable for automated appraisals.

Partner n3 implemented an automated text‑analysis solution built on InterSystems Caché with iKnow, using smart indexing and matching to extract and classify listing details. The system made over 90% of previously unstructured data usable, increasing available comparables, improving appraisal accuracy and data quality, and enabling scalable, cost‑effective integration into existing services.
