Large Universe Models in media monitoring

What it ingests

Wire services and publications, broadcast transcripts, social platforms, regulatory and court filings, analyst notes, and the organisation’s own statements and corrections.

The belief that matters

What the public record currently asserts about a subject, with confidence and attribution, rather than a sentiment score over a mention count.

Sentiment is the wrong abstraction

A sentiment average conflates a thousand neutral mentions with one substantiated allegation. It moves when volume moves, which is not when the situation moves.

A Large Universe Model holds specific claims as beliefs — this allegation is asserted by two outlets, one of which has a strong record; the company has denied it; a filing partially corroborates it — and reports when the weight of evidence behind a claim shifts.

Correction propagation

When an outlet corrects a story, everything that repeated it should lose weight. Because beliefs carry provenance, a correction reweights the original observation and confidence in the downstream claims falls automatically.

Limits

Judgements about source reliability are editorial and contestable. The defensible design exposes the weighting rather than hiding it inside a score.
