Forging an anti-terrorism search tool

Filed under
Misc

Google is the No. 1 free tool to snoop on friends or strangers. But government agencies including the Federal Aviation Administration are investing in a new search engine being developed at the University of Buffalo to do some of their more sensitive detective work.

The technology, released as a prototype in recent weeks, is designed to mine a corpus of documents for associated ideas or connections--connections between two unrelated concepts, for example, that would otherwise go unseen or would take countless hours of investigative work to discover. The project was specifically funded for anti-terrorism efforts and initially was used for searching over data within the 9/11 Commission report and public Web pages related to the suicide bombings carried out by terrorists who hijacked three U.S. commercial planes.

"Say you have the kind of question that connects these two people that we don't know about. You could start reading through all those documents. But our system is designed to look specifically for those evidence trails" that connect those two people, said Rohini Srihari, UB professor of computer science and engineering.

John McCarthy, professor emeritus of computer science at Stanford University, said that linking between concepts is an old idea, but that a new way of doing it could be an important breakthrough. In general, search engines such as Google and Yahoo mine documents for textual clues, or matches to query terms, rather than on the occurrence of ideas. Still, Google is working in the area of searching for concepts.

"The tools that we already have would be more useful if we could search on concepts," McCarthy said.

Srihari and a team in the Center of Excellence in Document Analysis and Recognition in the UB School of Engineering and Applied Sciences have been developing the search engine for the last two years. She said that her team plans to have a deliverable system for the FAA and the intelligence community by the end of the year, but it will not be widely available to the public. The underlying research, co-funded by the National Science Foundation, will also be published.

The technology, called a concept chain graph, uses different mathematical algorithms for finding the best path for connecting two different concepts. It will then list the strongest to weakest links.

Early Benchmarks Of The Linux 4.9 DRM-Next Radeon/AMDGPU Drivers

While Linux 4.9 will not officially open for development until next week, the DRM-Next code is ready to roll with all major feature work having been committed by the different open-source Direct Rendering Manager drivers. In this article is some preliminary testing of this DRM-Next code as of 29 September when testing various AMD GPUs with the Radeon and AMDGPU DRM drivers. Linux 4.9 does bring compile-time-offered experimental support for the AMD Southern Islands GCN 1.0 hardware on AMDGPU, but that isn't the focus of this article. A follow-up comparison is being done with GCN 1.0/1.1 experimental support enabled to see the Radeon vs. AMDGPU performance difference on that hardware. For today's testing was a Radeon R7 370 to look at the Radeon DRM performance and for AMDGPU testing was the Radeon R9 285, R9 Fury, and RX 480. Benchmarks were done from the Linux 4.8 Git and Linux DRM-Next kernels as of 29 September. Read more

How to Effectively and Efficiently Edit Configuration Files in Linux

Every Linux administrator has to eventually (and manually) edit a configuration file. Whether you are setting up a web server, configuring a service to connect to a database, tweaking a bash script, or troubleshooting a network connection, you cannot avoid a dive deep into the heart of one or more configuration files. To some, the prospect of manually editing configuration files is akin to a nightmare. Wading through what seems like countless lines of options and comments can put you on the fast track for hair and sanity loss. Which, of course, isn’t true. In fact, most Linux administrators enjoy a good debugging or configuration challenge. Sifting through the minutiae of how a server or software functions is a great way to pass time. But this process doesn’t have to be an exercise in ineffective inefficiency. In fact, tools are available to you that go a very long way to make the editing of config files much, much easier. I’m going to introduce you to a few such tools, to ease some of the burden of your Linux admin duties. I’ll first discuss the command-line tools that are invaluable to the task of making configuration more efficient. Read more

Why Good Linux Sysadmins Use Markdown

The Markdown markup language is perfect for writing system administrator documentation: it is lightweight, versatile, and easy to learn, so you spend your time writing instead of fighting with formatting. The life of a Linux system administrator is complex and varied, and you know that documenting your work is a big time-saver. A documentation web server shared by you and your colleagues is a wonderful productivity tool. Most of us know simple HTML, and can whack up a web page as easily as writing plain text. But using Markdown is better. Read more
