A Data
Fusion Approach to Indications and Warnings of Terrorist Attacks
|
Indications
and Warning (I&W) of terrorist attacks, particularly IED attacks,
require detection of networks of agents and patterns of behavior. Social
Network Analysis tries to detect a network; activity analysis tries to detect
anomalous activities. This work builds on both to detect elements of an
activity model of terrorist attack activity the agents, resources,
networks, and behaviors. The activity model is expressed as RDF triples
statements where the tuple positions are elements
or subsets of a formal ontology for activity models. The advantage of a
model is that elements are interdependent and evidence for or against one
will influence others so that there is a multiplier effect. The advantage
of the formality is that detection could occur hierarchically, that is, at
different levels of abstraction. The model matching is expressed as a
likelihood ratio between input text and the model triples. The likelihood
ratio is designed to be analogous to track correlation likelihood ratios
common in JDL fusion level 1. This required development of a semantic
distance metric for positive and null hypotheses as well as for complex
objects. The metric uses the Web 1Terabype database of one to five gram
frequencies for priors. This size requires the use of big data technologies
so a Hadoop cluster is used in conjunction with OpenNLP natural language and Mahout clustering
software. Distributed data fusion Map Reduce jobs distribute parts of the
data fusion problem to the Hadoop nodes. For the
purposes of this initial testing, open source models and text inputs of
similar complexity to terrorist events were used as surrogates for the
intended counter-terrorist application.

A
Mathematical Cyber Ontology (CybOnt) for Cyber Data Fusion and Cyber Data
Exchange
|
Silver
Bullet Solutions, Inc., with teammates CUBRC, Inc. and Edutainiacs,
Inc., is developing a mathematical ontology for cyber events, entities,
behaviors, associations, and intentions cyber Situation Awareness (SA)
and associated cyber Command and Control (C2) Network Operations (NetOps), Defensive Cyber Operations (DCO), and
Offensive Cyber Operations (OCO). This Cyber Ontology (CybOnt) will improve
interoperable data exchange between cyber operations nodes and enable data
fusion for detection of cyber attacks as they are being planned and before
they become incidents.

An
Information Fusion Framework for Data Integration
|
Despite
high demand for and years of dozens of product offerings, enterprise data
integration remains a manually intensive effort, with custom development
for each data interface. It involves linguistics, ontological models,
uncertain reasoning, inference, and other non-exact and not fully
understood sciences. This paper presents an approach for making progress in
data integration technology by paralleling progress made in the data fusion
community where the fundamental problems are now being appreciated. A
framework for information fusion as a means to achieve data integration is
presented.

Real-time
DBMS for Data Fusion
|
As
data and information fusion technology and application evolves, the need is
increasing to cope with large amounts and diverse types of data. Although
there would be many benefits to employment of Data Base Management Systems
(DBMS) in automated fusion processes the data access throughput
requirements of automated fusion processes have vastly exceeded the
performance of off-the-shelf DBMSs. The availability of large random
access memories is allowing the development of real-time data base
management systems. While these are currently being used in financial
market and telecommunications applications, their ability to bring DBMS
benefits to data fusion applications has yet to be explored. This paper
presents results of experimentation with these emergent real-time DBMSs
for automated fusion applications. We used algorithms, data
characteristics, and scenarios from deployed and R&D systems. The
applications-dependent data structures were converted to
Entity-Relationship models and generated into real-time and conventional
DBMSs. Keywords: Data Fusion, DBMS, real-time, correlation, knowledgebase,

Early
Experiments with Ontology-Based Fusion
|
There
is a growing sense in the fusion community that an underlying ontology
would improve fusion. We explored the idea and reported the results of
experimentation to ISIF in 2002 and 2003. In 2004 we have continued with
theory development and experimentation. The experimentation described in
this paper involved the development of a formal ontology from a data model
so that automated processes can reason dynamically, by virtue of onthe formal properties of the ontology relationship
types. The experimentation has been for a next generation fusion
architecture that is an open architecture in the well-documented sense that
adds an ontology layer for further decoupling and coordination of software
components. The experimentation has involved rehosting
of existing fusion algorithms to operate within the ontology and a
publish/subscribe architecture. While the experiments to date have shown
how the components can be made to interoperate at the data level, we
believe the architecture will ultimately promote or enforce probabilistic
interoperability between components providing a fusion open architecture at
the probabilistic level. Keywords: Data Fusion, ontology, semantic modeling

Airport
Movement Area Knowledge-Assisted Association and Tracking
|
This
white paper describes an approach for improving airport movement area
aircraft and vehicle tracking using knowledge-based techniques. This design
employs a knowledge-based fusion approach that would take into account
airport geography, vehicle movement patterns, static prior data, expert
rules, and sensor characteristics heuristics.

Bayes
Networks for Diverse-State and Large-Scale Fusion
|
Generalized
inference provides an elegant formulation for fusing sources that have many
diverse states that are nonetheless inter-related, be it in often in weak
and complex ways. Indeed, levels 1 through 3 fusion
can be characterized as inferring states from evidence; estimation can be
viewed as a specific inference discipline. Unfortunately, the elegant
inference formulation rapidly becomes intractably complex for any
real-world problems due to the permutations of interrelationships between
the interacting state variables. Bayesian networks provide a way of coping
with the complexity. Bayesian networks are techniques for making
probabilistic inference tractable and have been in broad literature and
research for quite some time. This paper describes the application of the
Bayes network technique to a real-world large-scale fusion problem. It
provides experience with the many adaptations and extensions that are
required and illustrates some issues that need further research. Keywords:

Multi-Hypothesis
Database for Large-Scale Data Fusion
|
Progress
in deploying large-scale fusion systems has been slow in recent years
despite substantial algorithmic developments. One reason is that there has
not been a way to address a large-scale enterprise in a tractable manner
that allows modular and collaborative evolution of fusion algorithms.
Information and data modeling techniques have become quite mature over the
past 20 years so that it is now possible to model the information domain of
a large-scale enterprise tractably.
By extending information modeling constructs to semantic and inference
nets, it is possible to use these information models as a basis for
large-scale fusion. This paper shows
how to instrument an information model into a fusion inference
structure. Algorithms encapsulation
and computing techniques are discussed. This approach could lead to
foundations for large-scale fusion in defense, intelligence, law
enforcement, and air traffic control systems. Keywords: Entity-Relationship Modeling, Semantic

Data Management for the
Warfighter Information Processing Cycle
|
The
Data Access Function (DAF) provides net-centric services and means to
access information within and relevant to the Warfighter Information
Processing Cycle (WIPC). Within the Combat
System, the DAF provides to sensor, track, reference, context, and sensor
tasking and queuing information. The
DAF consists of many data access services needed to meet the broad range of
QoS, IA, and topology requirements and
information types accessed across the WIPC.
The DAF helps WIPC services operate autonomously with respect to
each other; by separating the functionality of the service from the data,
the services interact via the commonly understood and accessed data without
any knowledge-of or explicit interaction-with each other.

Ontology-Based Inference with Inferlets
|
We
propose to develop a massive ontology and use it as a framework for
class-level inference for improved situation awareness. Our proposal is to
conduct research of concepts and preliminary experiments about which we
have written and presented conference papers at academic and DoD sensor and
information fusion conferences. If successful, the ontology-based approach
will leverage COTS database technologies and DARPA, ONR, AFRL, and other
fusion, inference, and cognition technologies. It will enable massive
fusion inference networks for weak evidence accumulation and long indirect inferencing to improve situation awareness. Our
approach is simple and elegant, yet rigorous and comprehensive.

Information Exchange
Requirements (IER) Driven Fusion
|
The
technical concept is has four principal elements:
1. Information Exchange Requirements Processor (IER-P) that decomposes IERs
to inter-related object and events and then links them to types of sensor
and source support evidence. This is
necessary since IERs are usually not directly observable but are, rather,
satisfied by fusion of multiple sensors and sources. The IER ontology dictates the workflow.
2. BrainLike Process (BLP) that tailors FMV and
imagery feature extraction to provide the required evidence
3. Sources Query Process that prepares Hadoop map
jobs to retrieve object and event of interest data from DCGS-N sources
4. Fusion Process that performs, 1) Hadoop
reduction using the returned DCGS-N key-value pairs, and 2) updates
likelihoods in realtime as sensor features arrive.
|
|
Pedigree in the Warfigher Information Processing Cycle (WIPC)
|
All
information in the WIPC has a source -- even a lineage of sources. Within the WIPC, information lineage is
referred to as Pedigree and information about
the source is called, Source Metadata (P&SM). Pedigree is a chain of observations or
object beliefs and along with a description of how
such observations or object beliefs were arrived at while Source Metadata
is a characterization of the source, whether it be
a sensor, individual operators, or a system of machines and operators. P&SM lineage describes how a piece of
information came about; P&SM descendancy
describes how a piece of information was used.

Next Generation Fusion
Architecture
|
This
project describes the creation of a Next Generation Fusion Architecture, an open
information architecture, for Command and Control (C2), and Weapons
Control systems that
require advanced sensor and data fusion. This Next Generation Fusion
Architecture provides a
foundation for advanced fusion algorithms including non-kinematic level 1
fusion, level 2 and 3
complex assessments, more broadly scoped Situation Awareness and Battle
Management
information analysis, and level 4 process adaptation.
The architecture supports increased
automation and higher quality data fusion through enforced integration and
integrity of data
thus allowing advanced mechanisms, such as ontology-based inference, as
well as the ability to
execute multiple kinds of fusion algorithms that interoperate autonomously,
yet synergistically

Analyzing
and Presenting Multi-Nation Process Interoperability Data for End-Users
|
Silver
Bullet was tasked by the DoD CIO to brief the International Enterprise
Architecture Conference in London in 2008.
International Defense Enterprise Architecture Specification (IDEAS) was developed
to deliver a unified specification for the exchange of military
architectures between coalition partners.
The nations/organizations are Australia, Canada, UK, USA and, as
observers Sweden & NATO. The
BORO methodology (http://www.boroprogram.org/)
is being used to re-engineer and deconflict
legacy systems. It,
1) provides a precise, mathematical approach to comparing information, 2)
is very easy to understand, and stakeholders readily commit to use the
methodology, and 3) is guaranteed to produce a correct representation, and
is fully transparent at every stage stakeholders are involved so buy-in is
kept all the way through. Its layers
are, 1) foundation based on Set Theory, 2) common patterns based on the
foundation, 3) domain patterns that specialize the common patterns. This fits well the many aspects of
interoperability: 1) communication,
2) system, and 3) procedural/doctrinal.
An experiment was conducted between the nations to address current
issues in warfare Casualty Management.
The use Cases are, 1) Scud missile attack in Desert Storm, and 2)
Operation Desert Storm Overall. The
conclusions are that exchanging architecture data during coalition
operations planning process can automate interoperability comparisons to
reduce resource requirements, speed the process, potentially detect issues
that may have been missed, and de-bias national interpretations of other
doctrines. But it depends on a
precise data exchange standard and IDEAS grounding in a formal ontology
provides such precision.
