Text Mining-based Ontology Extraction Process

This initiative developed an innovative Toolkit for Agent-based Knowledge Extraction (TAKE™). The TAKE™ technology applies a hybrid approach that combines ontology engineering methods with cutting-edge knowledge discovery techniques to extract, analyze, and map ontologies from distributed and disparate knowledge and data sources. These maps can then be used for the analysis and redesign of complex, multi-agent systems.

The TAKE™ technology provides innovative solutions that address the problems associated with rapidly designing, developing, and deploying large scale knowledge based applications. KBSI's overall approach in the initiative conceptualized and validated a framework and a methodology for sustainable knowledge management that encompasses the entire knowledge life cycle: capture/discovery, representation, analysis, validation, storage, retrieval, (in-context) delivery, and evolution over extended periods of time.

In the early phase of the initiative, KBSI established a novel TAKE™ ontology reuse and application method, designed innovative ontology analysis and ontology extraction algorithms, and designed the TAKE™ architecture. These innovations include the novel application of information fusion techniques for aggregated ontology similarity assessment and mapping the application of advanced knowledge discovery techniques for automated ontology extraction and mapping from multi-source text data. A demonstration of a prototype TAKE™ software tool was also demonstrated on a focused, high payoff Navy transition application scenario.

In Phase III, KBSI provided the requirements definition, design, research, advanced development, modeling, test, and training/mentoring for integrating the TAKE™ technology in Navy shipyards. This work included demonstrating the application of TAKE™ ontology-based technology capabilities to shipbuilding production planning challenges and the migration of the shipyard part catalog in accordance with Navy standards. 

KBSI first applied TAKE™ semantic mapping to the production of an initial shipbuilding production process and plan description lexicon and meta-ontology, to the development of modeling and semantic mapping methods, and to address the shipyard CPC legacy part migration. These requirements were validated at Tier 1 and Tier 2 shipyards and ship design software vendors who support interfaces to the Tier 2 CPC system. KBSI next researched method and algorithm extensions to support the defined requirements, and then designed and developed the TAKE™ architecture, algorithms, methods, and user interface enhancements in collaboration with the Tier 1 and Tier 2 community-of-interest. The enhancements developed in Phase III demonstrated how TAKE™ technology can be leveraged to help U.S. shipbuilders better achieve the goals of decreasing costs and increasing productivity.
