Surveillance, Personal Edition

June 2nd, 2009

Have you ever kept a calendar, tracked what you eat, or saved receipts? Simple data, like how much soda you drink, can tell a story:

Giving up Coke (or not) by Tim Graham

Giving up Coke (or not) by Tim Graham


In fact, what you drink can tell several stories. Here’s a more elaborate example, also by Tim Graham:
"I drink therefore I am" by Tim Graham

"I drink therefore I am" by Tim Graham


This is what we call self-surveillance.

What is self-surveillance? Read my article! (Also in PDF). Or Nathan Yau’s blog.

Also added to to the publications page: Nathan Yau & Jodi Schneider “Self-Surveillance,” Bulletin of the American Society for Information Science and Technology Vol. 35, No. 5 June/July 2009, 24-30. [HTML][PDF] . Thanks to Diane Neal (NCCU/U. Western Ontario), who edited the special section on Visual Representation, Search and Retrieval for this issue, and to the Bulletin’s editor Irene Travis and designer Carla Badaracco (who made the 16 figures work for screen and print).

Hat tip to Jenny Levine, whose “How Public is your Privacy” often comes to mind.

Stop Intellectual Apartheid

March 30th, 2009

A call to action from BYU English professor Gideon Burton: Stop intellectual apartheid!

Let me illustrate how academic institutions enforce Intellectual Apartheid through a simple experiment you can perform right now. Let’s say that you are researching lingering effects of South Africa’s apartheid and you discovered (as I did using Google Scholar) a recent article, “Fantasmatic Transactions: On the Persistence of Apartheid Ideology” (published in Subjectivity in July, 2008 by D. Hook). Now for the experiment: click on this link to the full text of the article.

One of two things just occurred. Either you just gained immediate access to a PDF version of the full article; or, more likely, an authentication window popped up requesting your login credentials. It turns out that Palgrave-Macmillan publishes Subjectivity, and through their website one can get access to this article for a mere $30. Alternatively, one may subscribe to the journal for $503 per year.

You really don’t need to go to the developing world to recognize that advanced knowledge is a big club with stiff entrance fees. Even middle class Americans will think twice before throwing down $30 for a scholarly article. How likely will this knowledge ever reach scholars in Mexico or India? And just how broadly can the editors of Subjectivity expect it to reach when subscribing costs $503/year?

Gideon also gives suggestions for scholars, librarians, and administrators.

Horizon scanning and the digital underbelly

March 29th, 2009

Gaynor Backhouse writes a great post about libraries, holding out for “a guided tour of the library’s digital underbelly”. My favorite part is her metaphor about horizon-scanning:

Horizon scanning is a bit like doing a jigsaw you’ve bought from a car boot sale: first of all, it comes in a plastic bag, so there’s no picture to guide you. Secondly, you can see from the myriad sizes of the different pieces that there’s more than one puzzle in there and, thirdly, you know, even as you are handing over your money, that you won’t have all the pieces to complete any one, particular puzzle. [JISC Libraries of the Future | Holding out for a hero: technology, the future and the renaissance of the university librarian.]

Gaynor manages JISC’s TechWatch, keeping up with tech trends for libraries.

I’m not quite sure what the library’s “digital underbelly” is. But this sampling of news art strikes me as one possible example.

Graphics section of the Chicago Tribune, September 9, 1938

Graphics section of the Chicago Tribune, September 9, 1938

The Art the Message: The Story Behind the Chicago Tribune Collection has the same feel of the behind-the-scenes tour Gaynor Backhouse described: “secret stuff” that only the curators know about. This collection was saved by Janet A. Ginsburg, who edits news aggregator trackernews.net and curates a collection of news retrospectives, hosted at her personal site.

For access to the physical collection (now known as the Janet A. Ginsburg Chicago Tribune Collection of the Michigan State University News Archive) contact MSU Communication professor Lucinda Davenport. Images from Janet’s news art exhibit can also be seen at Brainpickings and (with Portuguese commentary) at Segunda Língua. Found via Janet’s comment on Steven Berlin Johnson’s SXSW talk, Old Growth Media And The Future Of News.

Place versus location

March 27th, 2009

What’s the difference between place and location? My tentative answer:
A location has coordinates. A place has coordinates plus something more (culture, politics, maybe time).

I started thinking about this because of Paul David Erb’s twitter coverage of a talk at the Scholars’ Lab. I didn’t understand this tweet:

Places, not locations, provide the backdrop for historical events. The key idea is to map events and tie them to locations.

and Paul didn’t have a quick answer, either. After some unsuccessful searching for the original paper (which took me to several databases) and scanning citations from speaker Ian Johnson’s university bio page and “long bio [DOC]“, I started thinking about the problem more generally. Googling for “ian johnson” gis places locations led me to an interesting source: papers and presentations for Harvard’s China Historical GIS group. Lex Berman gave a concise explanation in one of his papers: [1]

If we are to take the sum of the information about what transpired at a
particular geographic location over the course of time, we must realize that
what we are not observing a single persistent identity, but a series of
historical instances. Each instance of an historical place, although it may
indeed be seen as occupying a certain temporal extent and geographic
extent, actually makes more sense in a political and cultural context which
expands and contracts.

He also says:

We have extensive historical documentation about the administrative units that were
established, abolished, re-named, or re-established in roughly the same
geographic space as today’s Beijing.

Those are all the same location. But they’re different places. Suddenly I understood (at least some small part of) the difference Ian Johnson must have been articulating.

My database searches, on the other hand, were a rich source of follow-up reading about space and place, on a variety of topics from computer science, to history of the book, to social science, to geopolitics. For me, database searching is great for keeping my fingers busy while engaging my head. And for turning up lots of things I’d like to read. However, I didn’t have enough data to figure out what paper Ian Johnson was referring to (something he wrote about places, locations, mapping events). In retrospect, writing him would have been most reasonable. Failing that, his profile might have been a better place to start. Other search strategies you’d suggest?

Remembering Sarah Seastone

March 24th, 2009
Sarah Seastone circa 2003

Sarah Seastone circa 2003

I never met her, but she was part of my life for almost a decade.

Sarah Seastone was the editor, archivist, and Web designer for the Math Forum. She helped numerous teachers create early webpages about topics like tessellations and fractals, and taught many of them about the Web. Here’s a definition she gave of the Web.

Sarah was a great encouragement to me when I started answering questions for Dr. Math, as an undergraduate in the mid 90’s. She always knew lots of resources, and was always happy to share them. A thread about women in math is typical. While I pressed “send”, Sarah contributed ideas. She knew and kept track of resources throughout the world.

Sarah was one of the first people I knew who really knew how to search the Web. Just about everything in the Dr. Math archives of that era was culled by Sarah as worth saving. As Dr. Math’s archivist, she must have read through a lot of the email sent by the project.

She also wrote many, many archived Dr. Math answers herself.

I knew her through email, sarah@forum.swarthmore.edu, and am sad to say I never met her in person.

PARC’s Mr. Taggy uses context from social tags

March 1st, 2009

PARC’s Augmented Social Cognition team is doing really interesting work. From time to time, new projects surface on their blog.

Last week, PARC announced the site Mr.Taggy.com, a search engine based on social bookmarking tags:

The problem with using social tags is that they contain a lot of noise, because people often use different words to mean the same thing or the same words to mean different things. The TagSearch algorithm is part of our ongoing research to reduce the noise while amplifying the information signal from social tags.

Mr. Taggy uses “related tags” to reduce the noise.

Filtering makes a difference:

Mr. Taggy results for void

Mr. Taggy results for void

Mr. Taggy search results for void, filtered by semantic web

Mr. Taggy search results for void, filtered by semantic web

Searchers can thumbs-up or thumbs-down each result to provide further context.

Bibliometrics with Google Scholar

December 22nd, 2008

New to me:
Software aimed at individual scholars whose work is referenced outside of ISI-listed sources.

http://www.harzing.com/resources.htm#/pop.htm

“Publish or Perish is a software program that retrieves and analyzes academic citations. It uses Google Scholar to obtain the raw citations, then analyzes these and presents the following statistics:

  • Total number of papers
  • Total number of citations
  • Average number of citations per paper
  • Average number of citations per author
  • Average number of papers per author
  • Average number of citations per year
  • Hirsch’s h-index and related parameters
  • Egghe’s g-index
  • The contemporary h-index
  • The age-weighted citation rate
  • Two variations of individual h-indices
  • An analysis of the number of authors per paper.”

Free for personal non-profit use; Linux and Windows versions

I’d be very curious to hear about research comparing it to other methods. The author is professor of management and marketing at The University of Melbourne.

Computational Thinking: quoting Jeannette Wing

December 13th, 2008

Karin Dalziel’s Why every Library Science student should learn programming reminds me that I’ve been thinking about, and meaning to write about, algorithmic (or computational) thinking.

What is computational thinking? It includes

  • Thinking Recursively
  • Thinking Abstractly
  • Thinking Ahead (caching, pre-fetching…)
  • Thinking Procedurally
  • Thinking Logically
  • Thinking Concurrently

That’s from Jeannette Wing slide 21 [PDF]; subsequent slides give examples. Or, if you prefer podcasts, she chatted about computation thinking with Jon Udell.

I would like to find examples of where librarians and archivists use computational thinking, especially outside the digital realm. It’s hard to argue that programming per se is needed for school media specialists or archivists. Some digital librarians and LIS educators also argue that, for digital librarians, managing programmers and interfacing with users are more pertinent skills than programming per se.

So I’d like to shift the debate. Instead of “should all LIS students learn to program”, I’d like to ask, what can LIS learn from computer science? Programming is only a very small part of computer science; as Jeannette M. Wing writes* [PDF]

Computer science is not computer programming. Thinking like a computer scientist means more than being able to program a computer. It requires thinking at multiple levels of abstraction

and

Having to solve a particular problem, we might ask: How difficult is it to solve? and What’s the best way to solve it? Computer science rests on solid theoretical underpinnings to answer such questions precisely.

Can LIS benefit from considering problems in this way? As a librarian or information professional, have you ever considered a problem from this angle? How did it turn out?
