General purpose

The idea is to build a technology news portal aggregating tech news from several sources and draw conclusions from them

  • find articles discussing the same news item as a provided text, but from a different source
  • get a different angle about a specific news item or topic from a different source
  • find controversial news in a period of time, that have been treated seperately from several sources.


Currently the dataset includes technical articles from the year 2017 and 2018, mainly from these source

The database contains around 200.000 articles and is growing by the week. It is updated every week with the latest tech news.

Currently deployed

Web application

The web application is currently accessible here.

Similar articles and conteroversial topics

You can find "controversial" topics in the database. You can browse through the articles that have been paired because the system considers it likely that they are talking about the same topic, possibly under a different slant.

Articles about the same stories can be found on the first page aggregated here.

Finding Related articles

You can copy the text of a technical article into this text page and find similar articles in the dataset, possibly limiting the search in a date interval.

Alternatively, you can see how articles in the database related to each other entering the url of an article in this page.

Browser plugin

Alternatively you can use browser plugins for Chrome or Firefox


This plugin adds a button on your toolbar. When you find an article on a tech news portal, click on the extension's icon on the toolbar to open a tab showing a list of articles related to the same story, gathered from other tech news portals on the site If the article cannot be found in Techcontroversy's database, it will be submitted for processing by the nightly batch - come on the next day to get results. The following tech news portals are supported: Arstechnica, Thenextweb, Theverge, Venturebeat, Techrepublic, Wired, Engadget, Gizmodo, Mashable, Zdnet, Digitaltrends, Theguardian, Qz, Inquisitr, Recode, Reuters, Techdirt, Inverse, Bleepingcomputer, Inc, Cnbc, Cnet, Forbes, Digit, Techtimes.
