Headup is a semantic web Firefox addon that presents the user with text and rich media content related to the objects and terms it identifies on the pages the user browses. In other words, it knows what you’re looking for based on what you underline on the web and provides you with relevant information in a contextually integrated pop-up window. This is a much less disruptive way to research information versus spawning another browser window or tab and Googling related terms.
Headup identifies people, companies, places, bands, movies, books and more and has a basic understanding of the relationships between them: For example, Headup understands that a “person” can work for a “company”, a “band” can publish a “track” and a “city” contains “places of interest”.
Headup is being developed by SemantiNet, an Israeli startup company founded in 2006 and based in Tel Aviv.
The tutorial video above doesn’t do Headup a great deal of service, but it’ll give you a sense of what’s possible through this semantic service. The rest is up to you.
Have a look/see and let me know what you think. I’m genuinely interested.
