Clue To Efficiency Of Complex Networks

Here meeting participants can follow and intervene Rosetta stone
real time during a meeting. It also enables people to catch up if they are late, with a complete summary of meeting progress to date.The summary is developed in real time by focusing on important sentences and phrases. Importance is established by the machine based on sentence length, keywords and the status of the speaker, for example the chairperson of the meeting. A remote participant can quickly get up to speed.Social dynamicsAnother example is social dynamics. A big problem for people accessing a meeting from a distance is the lack of socially dynamic context provided by text on a page. Gestures, for example, convey vast information that we intuitively acquire, but remains largely absent from the printed word. AMIDA developed software to record social dynamics of a meeting in real time.The software can track gestures, indicate gaze and head movements, and add speech bubbles to indicate who is speaking to whom.All this data is captured and available for later analysis and review. But beyond this value, the technology has a host of other potential applications like robotics, AI, and image recognition.For example, there are thousands of CCTV cameras in most modern cities, but they currently act passively -- they can be consulted after a violent crime, but it is very difficult to track them in real time. If software can detect gestures indicating Rosetta Stone Chinese
violence or aggression, however, the police could be alerted to a possible crime in progress.Or at a large, fractious public meeting, the chairperson might not notice someone has a hand up to speak, but AMIDA's software could capture that. Or a waiter with a Bluetooth headset could be alerted to a customer behind him trying to get his attention.These are just the obvious blue-sky applications where AMI could lead. The consortium studied dozens more -- most of which have potential commercial applications.Many people might, mistakenly, believe that this is the end, explains Bourlard. We have many significant research breakthroughs that deliver a suite of technologies which represent a large advance on the state of the art. Our work has put us in the lead internationally, and many of the technologies are currently in various stages of commercialisation.End of the beginningBut this is not the end, Bourlard states emphatically. This is just the beginning. We have taken technologies and enhanced them, then combined them in useful and effective new ways. But this is merely a platform from which we can make really impressive advances. We now have an effective set of working tools, but it is what those tools will enable us to do that really matters.Companies like Microsoft and NTT have caught on to the significance of what we areRosetta Stone Chinese Levev 1-3
doing and they are working hard to catch up. If we stop now it will not take them long to overtake us. On the other hand, other companies, like EADS and Nokia are developing collaborations with the AMI consortium.This is the point where Bourlard starts talking about web-ifying the real world, using AMI technologies already developed, and yet to come, to capture all the intangible and information-rich social data about human-to-human interactions -- information that remains largely invisible in the historical record.Bourlard describes enthusiastically a scenario with large meetings or brainstorming sessions which capture all the intangible date. So people can back track and see how a decision was made, what were the circumstances that led to it.It all means more accountability and transparency, and should in the near future lead to a better decision-making processes. Already, AMIDA-powered technology is transforming the worlds of business and education.The AMIDA project received funding from the ICT strand of the EU's Sixth Framework Programme for research.
