Searching for Numerical Data With Zanran

If you do quite a bit of online research, you know how hard it is to track down numerical data and statistics relating to a topic using mainstream search engines. Zanran can help.

The technology (or what are my powers?)

Currently in beta, Zanran is a search engine that looks for semi-structured data. That’s data in the form of images (e.g., charts, graphs) and tables. Zanran then takes  text near the image/table and focuses its search engine on that text. In its current form, Zanran extracts images and tables from HTML, PDF and Excel files. Future incarnations of the search engine will also be able to extract data from PowerPoint and Word documents.

What does this look like in practice?

Compare the results page for a search using “mobile learning statistics” as keywords in Zanran and Google.

Zanran currently picks up pdfs for this search and the results are quite different from what  Google’s search engine identifies (not necessarily better, but the differences are worth exploring).

A particular value-add of Zanran is the ability to hover over the pdf icon associated with a particular search result to get a clear view of the image(s) associated with it.

Using this feature, you can quickly hone in on the actual data that’s in the article.

Compare this to Google’s “hover” feature, which primarily focuses on text. (It’s not really a hover feature; you have to click on the magnifying glass icon by an article.)

Instructional strategies

If you read this blog, you know I don’t encourage reliance on a single search engine. Zanran is a useful tool for expanding searches, particularly when numerical data are important. It’s not 100% accurate in its ability to find images with numbers in them so you will get some non-numerical images in your mix. However, you’ll be able to quickly cull through these and you may find these articles interesting in any case. Most importantly, Zanran identifies articles you just won’t find readily using a Google search.

I’m definitely adding this search engine to my search engine collection on Symbaloo.

    I think that’s a fair summary.
    Please bear in mind that Zanran’s in beta – we’ll be improving it gradually over the next months. And we welcome suggestions/ideas (and bug-fixes).

    cheers
