Will Zanran be the Google for data?
The beta version of a data search engine is up and running. It has enormous potential, but it's still got some glitches.
Zanran is a new search engine, now in beta testing, that focuses on charts and tables. As its website says:Skip to next paragraph

Zanran helps you to find ‘semi-structured’ data on the web. This is the numerical data that people have presented as graphs and tables and charts. For example, the data could be a graph in a PDF report, or a table in an Excel spreadsheet, or a barchart shown as an image in an HTML page. This huge amount of information can be difficult to find using conventional search engines, which are focused primarily on finding text rather than graphs, tables and bar charts.
Put more simply: Zanran is Google for data.
This is a stellar idea. The web holds phenomenal amounts of data that are hard to find buried inside documents. And Zanran offers a fast way to find and scan through documents that may have relevant material. Particularly helpful is the ability to hover your cursor over each document to see the chart Zanran’s thinks you are interested in before you click through to the document.
Zanran is clearly in beta, however, and has some major challenges ahead. Perhaps most important are determining which results should rank high and identifying recent data. If you type “united states GDP” into Zanran, for example, the top results are rather idiosyncratic and there’s nothing on the first few pages that directs you to the latest data from the Bureau of Economic Analysis. Google, in contrast, has the BEA as its third result. And its first result is a graphical display of GDP data via Google’s Public Data project. Too bad, though, it goes up only to 2009. For some reason, both Google and Zanran think the CIA is the best place to get U.S. GDP data. It is a good source for international comparisons, but it falls out of date.
Here’s wishing Zanran good luck in strengthening its search results as its competes with Google, Wolfram Alpha, and others in the data search.
