JackalFish®: Ontology-driven Search Engine
Like any other large-scale industry managing
complex engineering projects, NASA and the
Department of Defense face the persistent challenge of
effectively discovering related information and data among
distributed project teams and information sources. The
Small Business Innovation Research (SBIR) office
addressed this challenge by awarding KBSI a multiple
phase SBIR project to design and develop an Ontology
Driven Integration Framework (ODIF) that establishes a
common ontology for integrating and searching diverse data
sources.
KBSI’s primary challenge was discovering how to best facilitate
the rapid gathering of knowledge among several project
teams. The Cape Canaveral Air Force Station (CCAFS)
and the 45th Space Wing were selected as the focus for
KBSI’s work because of the complex operations, data, and
information sharing needs required for their space launch
and range applications. KBSI’s Phase I ODIF effort determined
the theories and alternative ontology driven search
frameworks that might be used. The Phase II effort enabled
the rapid generation of applications for ontology driven
semantic searches, allowing participating organizations to
find information and data quickly across a variety of DoD
information systems and sources. In continuing to validate
the results of the Phase II effort, KBSI expanded the participants
to include the Missile Defense Agency (MDA), where
large complex projects are also managed.
“It’s the equivalent of Google on steroids” – Dr.
Perakath Benjamin, KBSI ODIF Project Manager
The JackalFish® software, the technology application developed during
the on-going Phase II effort, applies ontology-assisted text
mining and natural language processing methods to knowledge
extraction from unstructured text sources. The JackalFish® software allows users to perform targeted searches of
disparate data sources--unstructured and structured alike--
using keywords, extracted phrases from relevant documents,
common concepts, and/or defined ontology relationships. The
JackalFish® software, leveraging learning and selfadaptation
mechanisms from the ODIF framework, reasons
about the objects in the target domain and the relations
among the search items, returning only those data artifacts
or documents that are relevant to the search, including
knowledge derived from any predefined
ontology. This ontology learning
capability is based on a WordNet
approach enhanced by KBSI using statistical and machine
learning methods.
The JackalFish® software , by applying this ontology driven search capability,
significantly improves the cost, speed, and effectiveness
of extracting and integrating knowledge from
distributed, unstructured data sources and of sharing that
knowledge among distributed teams.
“It means the difference between extracting
information quickly and not finding it at all.” –
User, Patrick Air Force Base
As the DoD and large industries look to build the next generation
of information-integrated systems, the technology
derived from the ODIF project will provide a sustainable
mechanism for building ontology driven enterprise integration
applications. The immediate application for the JackalFish® software and the ODIF technology will be in facilitating
semantic information sharing and knowledge management
for space launch and range applications. But the JackalFish®
software also has a number of possible commercial uses, particularly
for large distributed organizations who perform knowledge
management, collaborative planning and scheduling, supply
chain management, or business intelligence.
