Bounce – A fun and easy way to share ideas on a website Smarter Metadata — Aiding Discovery in Next Generation E-book and E-journal Gateways Image via Wikipedia With the recent surge in library e-book sales, serials aggregators are racing to add e-books to their platforms. ProQuest’s recent acquisition of ebrary and JSTOR’s expansion into current journals and e-books signal a shift from standalone e-book and e-journal aggregator platforms to mixed content gateways, with e-books and e-journals living cheek by jowl in the same aggregation. Meanwhile, researchers have become accustomed to the big search engines, and have shifted from reading to skimming. As the authors of an article in the January issue of Learned Publishing, “E-journals, researchers – and the new librarians,” summarize: Gateway services are the new librarians. . . . These changes in behavior mean that gateway vendors have to develop more sophisticated tools for organizing and surfacing content. As discussed in a recent opinion post in The Atlantic Wire, consumers are recognizing the drawbacks of Google-style search. Like this: Like Loading...
Ben Shneiderman Ben Shneiderman (born August 21, 1947) is an American computer scientist, and professor for Computer Science at the University of Maryland Human-Computer Interaction Lab at the University of Maryland, College Park.

An Introduction to GraphViz GraphViz is a collection of tools for manipulating graph structures and generating graph layouts. Graphs can be either directed or undirected. GraphViz offers both graphical and command-line tools. A Perl interface also is available, but it is not covered here for reasons of generality. Some users like to use command-line tools instead of graphical ones, because command-line tools can be used with a scripting language. a traceroute representation of packages going to many destinations, taking the form of a treedatabase relations diagrams between tablesa graphical report for your boss, e-mailed automatically from a cron joba Web site mapUML diagramsRPM package dependencies on RPM-based systemssource code structure diagrams The package is available compiled for most Linux and UNIX distributions (see Resources).

Dynamic queries, starfield displays, and the path to Spotfire Ben Shneiderman, February 4, 1999 Updated July 26, 2007 Updated February 27, 2015 (Catherine Plaisant added mention of the cancer atlas prototype) The old days of command line interfaces and submitting queries to databases are passing quickly. In their place are dynamic queries and starfield displays that update a two-dimensional graphical display in 100 milliseconds. As users adjust sliders, buttons, check boxes, and other control widgets the starfield display containing color- and size-coded points us updated rapidly. Three early applications of dynamic queries were built at the University of Maryland's Human-Computer Interaction Laboratory (HCIL Video Reports 1992) -- a chemical table of elements (HCIL TR 91-11), a real estate HomeFinder (HCIL TR 92-01) (free downloadable version at and cancer atlas (HCIL TR 93-21.) Christopher Williamson's HomeFinder showed a map of Washington, DC and 1100 points of light indicating homes for sale.
Two colours in one node with graphviz's dot Spotfire Spotfire was a business intelligence company based in Somerville, Massachusetts. It was bought by TIBCO in 2007. History[edit] Spotfire's origins trace back to the Human-Computer Interaction Laboratory at the University of Maryland, College Park where, in the early 1990s, Christopher Ahlberg, a visiting student from Sweden, worked with Ben Shneiderman to develop applications of dynamic queries. On May 2, 2007 it was announced that TIBCO would buy the company.[2][3] See also[edit] References[edit] TIBCO Spotfire Version 6.0 Release - In Spanish Jump up ^ Dynamic queries, starfield displays, and the path to Spotfire (By Ben Shneiderman, February 4, 1999, updated July 26, 2007) Accessed May 18, 2009Jump up ^ TIBCO kauft SpotfireJump up ^ Datta, Saheli S.R.

Information visualization Graphic representation of a minute fraction of the WWW, demonstrating hyperlinks Information visualization or information visualisation is the study of (interactive) visual representations of abstract data to reinforce human cognition. The abstract data include both numerical and non-numerical data, such as text and geographic information. However, information visualization differs from scientific visualization: "it’s infovis [information visualization] when the spatial representation is chosen, and it’s scivis [scientific visualization] when the spatial representation is given".[1] Overview[edit] Partial map of the Internet early 2005, each line represents two IP addresses, and some delay between those two nodes. The field of information visualization has emerged "from research in human-computer interaction, computer science, graphics, visual design, psychology, and business methods. Data analysis is an indispensable part of all applied research and problem solving in industry. Stuart K.
