New software helps teams deal with information overload

04.06.2003


Penn State 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 originally developed by a team of researchers at Texas A&M where Yen was a key figure. Now a faculty member in Penn State’s School of Information Sciences and Technology (IST), Yen heads the Research Laboratory for Team-based Agents at the University while continuing to collaborate with Richard Volz and Michael Miller, from Texas A&M, on the software.



Initially, CAST was developed to facilitate or train human teams in the best ways to collaborate on and perform certain tasks. The research has been funded through a Department of Defense MURI (Multidisciplinary Research Program of the University Research Initiative) grant to Texas A&M, Wright State University and Penn State .

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.

Without being directed, members of higher-performing teams were able to provide each other with needed information. This enabled more timely and better decisions, he added.

CAST does this, too. "The more time-critical the environment in which a team operates, the more effectively it needs to process information," Yen said. "A computer program that acts as a team member may be more efficient in processing information than a human teammate."

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.

The software, which can be customized, also can help officers adapt more quickly to changing battlefield conditions.

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.

Yen had been scheduled to present this research as a keynote speaker at the second International Conference on Active Media Technology in the People’s Republic of China, May 29-31. The conference was canceled due to SARS. The paper, "On Modeling and Simulating Agent Teamwork in CAST," appears in the conference’s proceedings released by World Scientific Publishing Company.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
