Software maps ambiguous names in texts to the right person

February 27, 2014 3:19 pm | by EurekAlert! | News | Comments

If a name is ambiguous and given without context, even humans struggle. Researchers at the Max Planck Institute for Informatics have now developed a program that enables accurate disambiguation of named entities by analyzing them with the help of the free Internet encyclopedia Wikipedia. Their software named AIDA establishes connections between the mentions in the text and potential persons or places.

Battery-free technology brings gesture recognition to all devices

February 27, 2014 1:23 pm | by EurekAlert! | News | Comments

University of Washington computer scientists have built a low-cost gesture recognition system that runs without batteries and lets users control their electronic devices hidden from sight with simple hand movements. The prototype, called “AllSee,” uses existing TV signals as both a power source and the means for detecting a user’s gesture command.

Google Glass could help stop emerging public health threats around the world

February 27, 2014 1:10 pm | by EurekAlert! | News | Comments

The much-talked-about Google Glass — the eyewear with computer capabilities — could potentially save lives, especially in isolated or far-flung locations, say scientists. They are reporting development of a Google Glass app that takes a picture of a diagnostic test strip and sends the data to computers, which then beam back a diagnostic report to the user. The information also could help researchers track the spread of diseases.

Faster anthrax detection could speed bioterror response and save millions in decontamination costs, MU study finds

February 27, 2014 1:08 pm | by EurekAlert! | News | Comments

In 2001, letters containing anthrax spores were mailed to news outlets and government buildings killing five people and infecting 17 others. Currently, first responders have tests that can provide a screen for dangerous materials in about 24-48 hours. Now, researchers at the University of Missouri have worked with a private company to develop a new method for anthrax detection that can identify anthrax in only a few hours.
