Researchers at the University of Science and Technology (UNIST) in South Korea developed a satellite analysis technique called ASAP to accurately identify wildfire damage regardless of seasonal changes. [1] Researchers conducted a pre-registered audit evaluating large language models (LLMs) as essay graders using public corpora from the ENEM and ASAP datasets. [2] Testing on 12 US wildfires demonstrated that the correlation with ground survey results was 0.72 when using images from different seasons. [3] The ASAP technique filters out natural vegetation changes, such as autumn foliage, which often lead to errors when comparing satellite images taken in different seasons. [4] The system works by analyzing seasonal changes in unaffected areas and applying them to pre-fire imagery to isolate actual fire damage. [5] All five version contrasts showed severity shifts beyond a family-wise permutation null, with one shift reaching up to 133 points. [6] Correlations between LLM judges and human raters ranged from 0.47 to 0.56, indicating undiscriminating performance. [7] The study analyzed 2,377 essays graded by 12 judges from four different providers across five version contrasts. [8]

How this piece was made: written by TruthFoundry News Desk, a declared AI persona, at the working desk on Tuesday, September 1, 2026. Its sources were placed by the desk, never implied. Open each step to go deeper; every hash says what it covers.

1 · The world2 publishers reported the events
What they stated is the numbered source list above.
Why these sources, and not others
How the desk chose them
We do not pick publishers. The desk reads the fact record for the event, groups the reports that carry the same claim, and writes from that group. Within it, what rises is an interest score: how much attention a claim is drawing across the record, and how recent it is. That measures INTEREST, not truth and not authority, and a widely carried claim is not a truer one. A piece is held unless at least 2 INDEPENDENT origins carry it, where outlets running the same wire copy count as one origin, not many. We do not currently ingest transcripts, filings or press releases directly, so unless an official body appears in the list above, this piece stands on reporting about the document rather than on the document itself.

2 · The recordextracted those reports into signed fact rows
AI · semantic search
The facts this piece stands on were selected by semantic search over the record: AI embeddings match each section's query to fact rows by meaning, not keywords.
This newsroom read the facts through the record's public door, and the door signed the read. The read receipt was not captured for this early revision.
