Changes at "Implement "Talk to the City" into Decidim"

Is your feature request related to a problem? Please describe.
I am wondering how the platform "Brasil Participativo" ( based on Decidim) is currently handling the mass input from the more than 1.4 million citizens without becoming too convoluted or in the need for many volunteers.

I stumbled into this problem because I am looking for ways on how to scale mass online participation for political campaigns and participation processes over here in Germany.

Describe the solution you'd like
Semantic clustering of large-scale survey responses while preserving the diversity of views presented, combined with automatic summaries, visualizations and reports.

Additional context
https://talktothecity.org/
The tool has been used in during the vTaiwan process in combination with Pol.IS, as described in this report:

Does this issue could impact on users private data?
If used in combination with Pol.IS, the current lacking API would pose GDPR problems. A team in the netherlands has been optimizing Pol.IS for GDPR. Talk to the City itself has been developed in Taiwan and may thus also not be compliant.
