For those interested in measuring the fluidity of the online sphere and in particular how much online news coverage changes over time (from 404's to redirects to title and text editing), we've released this morning the new GDELT GDG, which recrawls every article monitored by GDELT again after 24 hours and after one week and catalogs all of the changes it observes. Text changes record only changes to the article text itself, not the surrounding page. Changes are reported at the "word" level for space delimited languages and character level for others (currently for Burmese, Chinese, Dzongkha, Japanese, Khmer, Laothian, Thai, Tibetan and Vietnamese, with more being added shortly). We're particularly excited about the ability to assess change globally across countries and languages and at scale, across everything GDELT monitors each day. The resulting global change log is all open data and available in one minute updates as JSON files, a BigQuery table and an RSS feed for web archives (allowing them to recrawl changed pages). This is an alpha grade release, so you will undoubtedly find some rough edges, but we're incredibly excited to see what people are able to do with it! https://blog.gdeltproject.org/announcing-the-gdelt-global-difference-graph-g... You can also couple this with our global frontpage outlink monitoring (35 billion outlinks to 240 million unique URLs to date) to assess what percent of homepage links are edited over time: https://blog.gdeltproject.org/announcing-gdelt-global-frontpage-graph-gfg/ Kalev
