Big Data Problem Plagues Government Agencies

Big Data Problem Plagues Government Agencies | Complex Insight  - Understanding our world | Scoop.it

Government agencies are collecting vast amounts of data, but they're struggling just to store it, let alone analyze it to improve efficiency, accuracy and forecasts. On average, government agencies store 1.61 petabytes of data, but expect to be storing 2.63 petabytes within the next two years. These data include: reports from other government agencies at various levels, reports generated by field staff, transactional business data, scientific research, imagery/video, Web interaction data and reports filed by non-government agencies. While government agencies collect massive amounts of data, MeriTalk's report found that only 60 percent of IT professionals say their agency analyzes the data collected, and less than 40 percent say their agencies use the data to make strategic decisions. That includes U.S. Department of Defense and intelligence agencies, which on average are even farther behind than civilian agencies when it comes to Big Data. While 60 percent of civilian agencies are exploring how Big Data could be brought to bear on their work, only 42 percent of DoD/intel agencies are doing the same.

Structural Design Principles of Complex Bird Songs: A Network-Based Approach

Structural Design Principles of Complex Bird Songs: A Network-Based Approach | Complex Insight  - Understanding our world | Scoop.it

Bird songs are acoustic communication signals primarily used in male-male aggression and in male-female attraction. These are often monotonous patterns composed of a few phrases, yet some birds have extremely complex songs with a large phrase repertoire, organized in non-random fashion with discernible patterns. Since structure is typically associated with function, the structures of complex bird songs provide important clues to the evolution of animal communication systems. Here we propose an efficient network-based approach to explore structural design principles of complex bird songs, in which the song networks–transition relationships among different phrases and the related structural measures–are employed.
