Dealing With Information Overload

By Roland Piquepaille

I wrote recently about information obesity. Now, this press release from Penn State University says that some of their researchers "have developed new software that can help decision-making teams in combat situations or homeland security handle information overload by inferring teams' information needs and delivering relevant data from computer-generated reports."

The agent software called CAST (Collaborative Agents for Simulating Teamwork) highlights relevant data. This helps improve a team's decision-making process as well as enhances members' collaboration.
"This version of CAST provides support for teams by anticipating what information team members will need, finding commonalities in the available information and determining how that information should be processed," said John Yen, professor of information sciences and technology. "Decision making is made easier because the software offers only relevant data."

CAST was developed for training human teams to better collaborate, but quickly adopted new goals.

With this research, the research team is taking smart software into a new direction involving what he calls "shared mental models" to support team activities or train teams. These can include shared team goals, shared assumptions about the problem, and shared knowledge about the team structure and process.
"The inspiration came from psychologists studying the behavior of human teams who were required to process incoming information under the pressure of time constraints," Yen said.
The Penn State researcher and his collaborators see CAST as a promising technology for supporting military officers who receive from ground sensors and satellites as many as 600,000 reports every hour. Without the right information, the wrong decision can be made in the battle space, Yen said.
CAST also could be used to track potential terrorist threats or infectious diseases -- any domain where information needs to be exchanged quickly or commonalities found among different cases, Yen said.

Of course, this is just a press release, so it is unclear if this project becomes a product anytime soon.

Famous quotes containing the words dealing with, overload, dealing and/or information:

    Undecidability is a useful category even in dealing with restaurant menus.
    Mason Cooley (b. 1927)

    I am a dreamer of words, of written words. I think I am reading; a word stops me. I leave the page. The syllables of the word begin to move around. Stressed accents begin to invert. The word abandons its meaning like an overload which is too heavy and prevents dreaming. Then words take on other meanings as if they had the right to be young. And the words wander away, looking in the nooks and crannies of vocabulary for new company, bad company.
    Gaston Bachelard (1884–1962)

    You’ve been trying to keep an honest accounting of city monies. You’ve been dealing with politicians. You’ve been standing up for your own rights, haven’t you? Naturally you landed in jail.
    Dalton Trumbo (1905–1976)

    When action grows unprofitable, gather information; when information grows unprofitable, sleep.
    Ursula K. Le Guin (b. 1929)
