Methodology

How we analyse public consultation feedback.

Petram applies a declarative extraction schema to every submission in scope of a consultation. Each submission is classified across four dimensions: overall stance, topics discussed, arguments invoked, and entities referenced.

Extraction

A consultation-specific schema is defined with the client's regulatory frame in mind. A large language model reads each submission against the schema. Every extracted value is accompanied by a verbatim evidence quotation from the source text.

Validation

Outputs are validated against a typed schema. Invalid or incomplete extractions are re-run and surfaced as a separate quality dimension — never silently discarded.

Campaign detection

Near-duplicate submissions are clustered by linguistic fingerprint and temporal submission pattern. The result is a separation of independent stakeholder voices from coordinated campaign volume — each measurable in isolation.
