Piranha

There is a massive amount of intelligence data available that cannot be manually analyzed. Computers can provide some help in this problem, but the shear volumes of data make the most promising approaches impractical. The challenge is for a computer to sift through a large amount of data & provide a human with accurate and relevant information, not to merely allow the analyst to search over an ever increasing set of data. This requires software that is able to filter, relate, and show documents & relationships to an analyst.

CIPHER: Counterintelligence Penetration Hazard Evaluation and Recognition

A great deal of very sensitive information (from personal credit card information to nuclear weapons design) resides on a very wide collection of computer networks. Various illicit groups use a wide variety of means (unsophisticated, semisophisticated, and highly sophisticated attacks) to gain access to this highly sought after sensitive data. The unsophisticated and semi-sophisticated types of attacks can be easily identified. However, there is no method available to prevent the “low and slow” attacks from sophisticated attackers.

I2IA: Image to Intelligence Archive

An enormous volume of geographical data is being produced on a daily basis throughout the world and is being analyzed to create scientific, military, and intelligence information. Two significant challenges that exist in producing this image information are: managing the vast amount of available and increasing data, and automating the manual processes that are currently needed to produce and search this type of information.

ORION

Actionable intelligence is critical for threat-vulnerability analysis and for assessing potential terrorist threat scenarios.  However, the lack of an automated information discovery and analysis system that allows fast and effective retrieval, analysis, and fusion of information severely weakens the effectiveness and efficiency of using all available information for decision-making and threat analysis.  Currently, experienced analysts must perform fusion of such information.  As a result, much of the staggering collection of information is not utilized or significantly underutilized. Utilizing ORNL’s expertise in information analysis and fusion techniques, these challenges can be met using an agent-based information analysis and fusion system.

Agent Simulation

Scientists who use simulation models to better understand physical phenomena commonly deal with massive datasets. The output of such a simulation can often be terabytes in size, widely distributed, and may require months of supercomputing time to produce.

Machine learning

At the foundation of many applications that perform analysis over sets of natural language texts lies the task of extracting information into a structured form. Despite some demonstrable successes, Information Extraction (IE) suffers from a major flaw in most real applications. The extraction task for which a tool was built is rarely identical to the task on which it is deployed, and shifting IE tools to new textual domains (e.g. from newswire to emails) results in significant performance drops, even for simple types of extraction and even for slight shifts in domain. The errors propagate through multiple subtasks resulting in even more significant performance reductions for more complex tasks. Modifying extraction systems to work on new domains or new tasks has traditionally been a tedious process and the cost was not always justifiable.

Ant Swarming

Some problems are too complex to be solved by agents’ work individually. The emergent behavior (EB) provides a synergistic ability for a collection of intelligent agents by producing better solutions to a problem than the sum of the abilities of all agents when they work individually. However, designing an agent system with EB properties is different than designing the traditional multi-agent system (MAS). In traditional MAS, the problem solving solutions are pre-programmed inside each agent. However, in an EB enabled agent system, neither individual agent has enough intelligence nor any goal or intention to solve the problem. The problem’s solution emerges from the agents’ direct or in-direct interaction(s). Scientists and/or engineers are challenged to build such a system.

GPU Text Analysis

In the last decade, an explosion in the amount of available digital text resources has occurred. It is estimated that the Internet contains hundreds of terabytes of text data, a sizable amount of which is in an unstructured format. We will soon reach a point where terabyte-scale text corpora are routinely used on personal desktops for the purposes of research and decision making. However, most current text processing algorithms work well only on small corpora and are difficult to be scaled to the terabyte level on desktops because of the lack of enough computing power. Even running some simple text analysis tasks can take days or weeks of computer time to process a relatively large collection of data.

Threat Assessment

Assessing the likelihood of a situational threat is challenging due to the complexity of merging data from disparate sources and different formats. In addition, those factors in the situational context that affect the accuracy of observed measurements must be considered.
