Zemanta is a content and links suggestion plugin for publishers, bloggers and other content creators.[1] It suggests links to context-relevant articles. It also suggests images found on internet that are context relevant, as well as keywords, and tags. The suggestions are delivered to the users through a point and click interface.


The company launched in 2007 after being chosen as a winner of Seedcamp 2007 and was venture funded by Eden Ventures, Union Square Ventures and T.A.G. The Accelerator Group. It has offices in New York, London, and Ljubljana.[2][3]

Other companies have used Zemanta's API to add content suggestion to their products, for example hover.in, Triond, RetailFans, Bukisa and Faviki.


The Zemanta browser extension works within major browsers (Internet Explorer, Firefox, Chrome), as well as a plugin for WordPress, Blogger, TypePad, Ning, MySpace, LiveJournal, MovableType, Tumblr, Drupal and Joomla. It is now also available for use with web-based email systems like Gmail, and Yahoo mail.[4] A Microsoft Outlook add-in is in development. Zemanta's server analyzes user-generated context-relevant content (e.g. a blog post) using natural language processing and semantic search technology. The links suggested are from Wikipedia, YouTube, IMDB, Amazon.com, Crunchbase, Flickr, ITIS, Musicbrainz, Mybloglog, Myspace, NCBI, Rotten Tomatoes, Twitter, Facebook, Snooth and Wikinvest, as well as the blogs of other Zemanta users.

Zemanta's understanding of the content (e.g. whether "Apple" refers to a fruit or a company) can be embedded into the content using Common Tag[5] for semantic tagging.


Zemanta used to be based in part on Jožef Stefan Institute national research institute's TextGarden content analysis software. The company was member of Ljubljana University Incubator and Ljubljana Technology Park.[6]

Its first application was used to suggest links from transcripts of Slovenian public TV shows to context-relevant content.[6]
