Hamburg's DIPAS platform uses fine-tuned LLaMA and RoBERTa models to automatically cluster and summarise thousands of citizen comments on urban-planning consultations, work that once took five staff over a week — and has since spread to nine other German cities.

Context

DIPAS is Hamburg's platform for citizen participation in urban planning, launched 2017 by the Ministry of Urban Development and Housing with HafenCity University's City Science Lab.

Activities

Since 2023, DIPAS has integrated fine-tuned LLaMA and RoBERTa models that cluster citizen contributions by theme, distinguish problems from proposed solutions, and map comments to locations.

Results

A cycling-concept consultation drew over 3,000 contributions; a comparable consultation previously required 5 full-time staff more than a week to process manually. DIPAS has since been adopted by 9 other German cities.
