IST-Data Services Blog

The topic of Big Data and the associated trends for research are part of our future here at DS. The recent issue of Nature looks at issues and trends around the topic, and while uneven, has some good material in it that folks should check out. Here’s my blow by blow on the sections:

The opening editorial calls for push to make annotating data be a major component of research and of grants. Sound familiar? Let’s hope funders listen.

The section on the next Google trots out a lot of familiar and frankly pretty dull options. Skip it.

Big data: Data wrangling poses important question about data collection. We might have the sense is that there is so much data, it is just a matter of managing it. However, David Goldston notes that there are also huge holes in the dataverse, and these are a result of political policy. Further, if a political entity controls the data, politics can (and will) shape and filter the data in fair-reaching ways.

Cory Doctorow’s Gee whiz piece is irritating (unless you’re into technoporn), and is easy to skip.

A piece on wikiomics is an excellent description of how community can make a difference, and the social dynamics of a collaboratory.

Cliff Lynch has a good piece on what data production projects must do to rationalize their data management, and what services must be provided by groups like IST/DS, to support these projects.

Frankel & Reid present an interesting discussion of mining and visualization, and include a compelling, cautionary note:

“The ingrained habits of highly trained scientists make them rarely as adventurous as these young minds. We think we are on the path to insight when shading reveals contours in 3D renderings, or when bursts of red appear on heat maps, for example. But the algorithms used to produce the graphics may create illusions or embed assumptions. The human visual system creates in the brain an apparent understanding of what a picture represents, not necessarily a picture of the underlying science. Unless we know all the steps from hypothesis to understanding — by conversing with theorists, experimentalists, instrument and software developers, visualization scientists, graphic artists and cognitive psychologists — we cannot be sure whether a display is accurate or misleading.”

The closing essay is human interest and could be skipped in the interest of time. However, it is short, and like the best human interest stories, is surprising and inspiring.
