The Guardian newspaper is one of the most respectable news brands in the world and carries a wealth of articles, news reporting and other quality content. Today they announced Guardian Open Platform API, that allows application developers to leverage this information in their applications. To explore their new API, we built our own mashup on top of it by combining Zemanta API with Guardian API to create Guardian topic researchr.
It's an interactive topic explorer around Guardian's articles. The way it works is that you search for a certain term (using Guardian API), resulting articles are then sent through Zemanta's Semantic API, to extract main concepts from articles. You can then explore these concepts further in a seperate window or view and filter articles.
Give Guardian topic researchrÂ a try and let us know in the comments what you think and if you're application developer, don't forget to check out Guardian Open Platform API as well as Zemanta's Semantic API.
