ASIS&T 2011 – Day 1

Last week was ASIS&T 2011. I put together a series of blog posts, one to cover each day. I had every intention of making them pretty, but it’s been a week and it doesn’t look like that’s going to happen. So here — in raw form — are my notes from Sunday, Oct. 8, 2011.

Plenary Speaker:

Tom Wilson, Visiting Professor University of Borås, Sweden
Preservation — the Final Frontier?

Story time! The year is 3511. Once upon a time… Paper > computers (limited memory, sent over wires) > intelligent robots
who created these ideas?
now 3511, they know everything of past…

Physical materials can have long lifetimes if conditions are correct & w/o natural (or human) disasters.
Preservation little value if items cannot be interpreted (ex. Rosetta stone as key to heiroglyphics)

Many modern storage mediums not designed to be durable — microfilm more durable than DVDs, VHS, slides, etc. Best? Archival acid free paper. ~1000 years

Formats lead to intelligibility problems. Change in language (same as words) can be depreciated and leave very a fine thread over time.

Talk about videodisks… bye bye. 🙁 1986 domesday book ( lost until this year. File formats disappeared, machines gone. Had to reconstruct. “Let’s hope that the Web lasts a little bit longer!”
How are we even sure we’re getting the entirety and not losing pieces in conversions? LOCKSS (Lots of Copies Keeps Stuff Safe) — How many ever reused? How long until reading capabilities of a file type is lost?

In past 5 years, digital is 10x larger. Amount of digital data almost equivalent to the number of stars in the galaxy. By 2026, Avogadro’s number.

Data creation is now outrunning the amount of available storage. Gap increasing almost exponentially. What gets preserved for digital future will be as much of an accident as the preservation of items from the distant past… What will be valued in the future? What resources are available to keep those items for the future?

Oil reserves estimated to run out by mid-century. Implications on energy creation and therefore digital information endurance.

Social Tagging and Folksonomies
Short 10 minutes each, panel of 6.

Faceted navigation of social tagging apps… how to incorporate into social tagging? Control in an uncontrolled environment.
Catalogue as a social discovery tool (think LibraryThing). Helps connect like-minded people
Motivations for tagging. Why do some people tag and others do not? Quick adoption w/ fast fall-off.
Cultural indications: identify needs of the community.

Tagging for emotions, Dianne Neal
Higher agreement on tags on visual items rather than audio items.

Happy visuals tend to feature smiling happy portrait (44/100), subjective (22/100), textual / inside story (6/100, needed text to interpret)
Canada very curious about digital perceptions of their country, hence funding of study.
What about associations — clusters of words often found together?

Do tag clouds benefit users in search results? Place tag cloud to right of results list. Tested by time, cognitive effort through clicks & eye tracking. Overview tag cloud helped form more efficient queries, less query volume, no time difference. Less regression.

Retrieval potential of tags
Tagging often see as a way of producing low-cost metadata
author keywords compared to tags perform about the same
