“Zanran focuses on finding what it calls ‘semi-structured’ data on the web. This is defined as numerical data presented as graphs, tables and charts – and these could be held in a graph image or table in an HTML file, as part of a PDF report, or in an Excel spreadsheet. This is the key differentiator – essentially, Zanran is not looking for text but for formatted numerical data.”
It’s got some nice features, especially the preview a pdf facility which you can do by hovering your mouse over the links. Take a look at it and let us know what you think.
