In this article, the authors present a methodology for utilizing ontologies to enhance the process of graph matching in fusion applications, particularly those associated with soft data (e.g., linguistic data existing in things such as intelligence messages).Abstract:
Ontologies are being used increasingly in fusion applications, particularly for higher-level fusion, where data must often be understood relationally. This research presents a methodology for utilizing ontologies to enhance the process of graph matching in fusion applications, particularly those associated with soft data (e.g., linguistic data existing in things such as intelligence messages). This paper presents some of the considerations and challenges associated with merging the technologies of ontologies and graph matching, as well as some preliminary research findings that show the effectiveness of using ontologies to enhance the matching capabilities of target graphs (as relational items of interest) against larger data graphs.read more

High-level Information Fusion: An Overview.
Pek Hui Foo,Gee Wah Ng +1 more
TL;DR: In general, data and information fusion can provide enhancement to the outcomes of processes for solving various application problems and improvement in situation awareness (SAW) and inference that lead to better decision making.

Ontology-based subgraph querying
TL;DR: The ontology-based subgraph querying is introduced, which revises subgraph isomorphism by mapping a query to semantically related subgraphs in terms of a given ontology graph, and a metric is introduced to measure the similarity of the matches.

TL;DR: This paper presents a soft information fusion framework for creating a propositional graph from natural language messages with an emphasis on producing these graphs for fusion with other messages.

Experiences and Challenges in Automated Support for Intelligence in Asymmetric Operations.
TL;DR: This paper presents a meta-modelling system that automates the very labor-intensive and therefore time-heavy and expensive and therefore expensive and expensive process of integrating sensor data and information fusion into a computer system.

No-but-semantic-match: Computing semantically matched xml keyword search results
TL;DR: This paper studies the no-but-semantic-match problem on XML keyword search and proposes a solution which enables the top-k semantically related results to the user and develops two query processing algorithms based on the pruning techniques.

An Ontological Analysis of Threat and Vulnerability
Eric Little,Galina Rogova +1 more
TL;DR: This paper discusses the formal ontological structure of threats as integrated wholes possessing three interrelated parts: intentions, capabilities and opportunities, and shows how these elements stand to one another, as well as to states of vulnerability.

Ontology meta-model for building a situational picture of catastrophic events
Eric Little,G.L. Rogova +1 more
TL;DR: An attempt to confront this challenge by utilizing formal philosophical categories and theories to design a formal ontology of catastrophic events that describe the most basic and relevant structures of objective reality.

Use Cases for Ontologies in Information Fusion
Mieczyslaw M. Kokar,Christopher J. Matheus,Kenneth Baclawski,Jerzy A. Letkowski,Michael L. Hinman,John J. Salerno +5 more
TL;DR: This paper develops use cases in which ontologies are used both for the fusion process itself and for the development of fusion systems, covering scenarios in which the agent roles are played by people, software or both.
