JCDL 2006 Conference Notes



Day 2 – Session 1 – Visualization for Libraries

1st talk: etana – dl presentation: archeology dig library
browse by space, object, time for archeologists

visualizaton system wth hyperbolic trees; used for analytics – e.g., loking at a specific time period and % of bones found

28 studnets worked with the sytem for usabilty study; various tasks students performed

interesting feature of page: can save the breadcrumb path – well-liked by the students in usaiblity test

conclusions: approach dl based on dl theory;

lemmas : searching and browsing are the same; can produce the same results; go through a searching process and get a set of reseults and go through browsing, there's an inverse relationship; browsing results associated with a navigated path: relationships with the browsing sequences;

q: presenting things visually when dealing with more formats; but, it's not.

dicussion: information exploration; visualization; exploratory searching; tough to evaluate information visualization systems

difficulty with usabiliy studies in these systems; maryland will run a workshop on how to evaluate info visualization systems;

2nd talk: mixed-initiative system for representing collections as compositions of image and text surrogates – combiformination presentation (andruid kerne)

interface ecology lab -texas a&m computer science department

combinFormation;

information discovery: emergence of new ideas; information serves a stimulus; intellectual tasks; collecting new sets of existing information resources; ability to manipulate to support information discovery

surrogate: comes from library science; representing the original – let's you access the original

digital surrogate: special type of hyperlink; formed systematically from metadata; eclipses the object;

text-based surrogates breakdown when you want to see relationships

images + text: working memory; separate cognitive resources; seems like a good idea to engage both together; e.g., video surrogates, navigational surrogates – overwhelmingly users prefercompositional format compared to text-based formats

composition: assemble collected elements to form a connected whoe; visual composition; spatial organization; compositing; fading

people understand this visual composition better;

mixed-initiatives: user and agents working concurrently; requries dialogue and feedback

combinformation: mixed-initiative composition of surrogates; composition space: space where composition is created; user can manipulate it; search it

launch demo: combinFormation – can search rss feeds, flickr, allow crawling into, the web, web site; can have as many searches as you like; can put together information from more than 1 search; crawler paths: crawling deeper into each site and crawl anywhere (follows cross links)

(java based) socket connection btw browser and application

uses google to run the searches and then it will download pages from initial searches and images patch up with text – VERY COOL!!

when you mouse over the surrogate, there's structured metadata: location, the gist (what google said about the page), title

user can move images using the grab tool; resize; you can create the composition in the middle of hte page; the "cool space" just for user; the "hot space" is shared with the agent

MAIN THEME OF THE SYSTEM: users can create a composition of their own images and search results by drag and drop technology; this becomes the user space;

metadata: details on demail in context rather than forcing the user to look elsewhere; deployment was i a class called the "design process"; experimented with 182 students; asked them to use combinFormation (divided the class – group A & group B). could only use combinFormation on 1 project; findings: students did better on both parts of the assignment when using combinFormation;

benefits: qualitative approach to collection visualization -using image and text together; using visual communications techniques (get both html & xml version of your composition space); users see some unexpected results; serendipity like physical library stacks;

future work: better semantic modeling; alternative visualizations; discovery tasks are not finding tasks;

3rd talk: infogallery: informative arts services for physical library spaces
center for interactionspaces; research project on future hybrid libraries;

i floor: interactive flooor

info-column: digital "poster-column" exhibits electronic publications; librarians promote library resources;

info-gallery concept: exhibit digital resources in the physical space; natural pick up of digital materials;

look at chalmers university, play group and georgia tech, info canvas

presentation interface: "remarkable" visualizations and animations of infobjects; surrogates floating around; users can come by and pick them up in the physical environment

look at royal library for information distribution channels; editors showing up on different channels

pick up of digital resources by bluetooth phone or by email address; fully web-integrated architecture; http, mysql, xml, .net, flash; rss integration; sensor layer for bluetooth

different appearances: walls, floors, smart boards, plasma, projections; workstations

can't really describe how incredibly new age and cool this product is!!! bouncing balls on an interactive display, push the ball and you get more information about the digital object or go directly to the original resource; can send yourself an email of the digital resource; can inspect digital channels; can create new concepts for saving as rss feeds

how's it's used: 65 librarians producing content; 50 channels; 250 interactive objecs on avg.

placed the galleries in the physical library at the desk, the refreshment areas; book-return matchine and moving these galleries to various parts of the city – reach users that don't come to the physical library;

future: working with local artists on different "skins"
