knowledge graph

Established · tracked since 2 September 2026 · first seen 4 August 2026

Established Established: present through the month at a steady pace.

Counted every morning across Hacker News, Google News, GitHub, arXiv and Reddit, from each platform’s own search interface, with the documents the counts were read from listed below. This page is rewritten with every run; the run it stands on is .

  • Also counted as: knowledge graphs
  • Entered the watchlist as an editorial decision — Editorial seed, 2026-09-02: an older idea returning as the grounding layer under retrieval.
  • Carried in the last thirty days by: Hacker News · Google News · GitHub
  • Wikipedia: Knowledge_graph — 7,859 page views in thirty days, counted apart from the mentions

The term and each of its declared aliases are searched as one quoted phrase through every platform's own search interface, once a day; matching documents are deduplicated by URL, and each document counts once however often the phrase occurs in it. The three windows end at the run, so seven days means the seven days before this morning. A platform marked as possibly undercounting returns at most a fixed number of items per query, so its thirty-day figure is a floor rather than a count. Page views are shown where the watchlist names a Wikipedia article and are never added to a total — they are readers, not documents.

May undercount: Google News, GitHub — the feed returns at most a fixed number of items per query, so the thirty-day figure is a floor.

The arc

One bar per committed run, oldest on the left, tallest bar = 9 mentions in a day. The two brackets are the windows the status word rests on: the last seven runs, and the three weeks before them. The table below is the same data, day by day.

One point per committed run, oldest on the left, read out of the dated files in src/data/trending/terms rather than from any stored series: a day the machine did not run has no bar, and a day that counted nothing is drawn as a hairline, because a measured zero is still a measurement. The strip is as long as the archive, which is why a term added recently has a short one.

Receipts

The newest documents the counts were read from — title, platform and date, nothing else. The bodies are not stored anywhere: the receipt exists so a reader can open the source and check the count themselves.

How this is measured

  1. A term is a phrase, not a subject: it is counted when it or one of its declared aliases occurs in the title of a document a platform returns for that quoted phrase.
  2. Each document counts once. Duplicates are removed by URL, so one story syndicated to five outlets counts as the number of distinct URLs, not as five mentions of a topic.
  3. The windows end at the run, not at midnight: one day, seven days and thirty days back from the moment the machine asked.
  4. The status compares the seven-day count with the three weeks before it against thresholds committed in the pipeline. No editorial judgement enters, and no model is called.
  5. The first sighting is the earliest receipt across this run and every committed file, so it can only move backwards — never forwards, and never to today because the archive is young.

No language model writes anything on this page: the count is a platform’s own answer to a quoted phrase, the status is a threshold in the pipeline, and the sentence above the numbers is assembled from them.
