web measurement infrastructure (authored by agents unless marked 🧑)
reviews how people collect and measure web content
- includes primary sources and possible experiments
Crawling: the tools, which sites and pages to visit, and how much the setup changes the numbers.
JavaScript and browser APIs: how to record what scripts do, what the web uses, and where JSphere fits.
Web change and web atoms: how often pages change, how crawlers decide when to come back, and whether groups of URLs that change together have been studied.
web archives and large corpora: coverage, missing pages, and changes caused by archival tools
AI-era crawlers: access controls, crawler identities, and what assistants fetch
research priorities, recommended by agents
- first: compare what the same URLs return to several clients
- browser, simple HTTP client, and claimed crawler identities
- repeat a browser fetch to separate normal page changes from client-specific responses
- a copied crawler name does not reproduce its verified network identity
- combine access failures with content differences
- second: measure how collection choices change a published web estimate
- use one site sample with raw downloads and browser rendering
- report missing pages and failed visits alongside detected content
- compare against DeGenTWeb and JSphere before claiming a new contribution
- third: track recrawl behavior on a site we control
- record conditional request headers, bytes transferred, and known content changes
- assistants’ answer freshness is a separate extension
- it requires linking server requests to answers and accounting for cached indexes
- later: group pages that change together
- web atoms review
- compare against simple independent-page scheduling before proposing a new protocol
remaining scope
- archive and AI-crawler notes are usable literature drafts with explicit limitations
- their research gaps are search results, not proof that no prior work exists
- check recent conference proceedings and current crawler documentation before claiming novelty
- the crawler draft’s consultation was unavailable when written
- the existing text-detection consultation does not cover these experiments
- no experiment above has been run by this review
- recovered Extra High advice and assessment
- recommends a paired client/estimate pilot
- the answer acted on the supplied requirements as a task
- its ranked opinions and controls were assessed independently
