This report provides an overview description of the Integrated Cooperative Decision-Making (ICDM) software toolkit for the development of intelligent decision-support applications. More technical descriptions of ICDM are contained in a companion CDM Technical Report (CDM-18-04) entitled: 'The ICDM Development Toolkit: Technical Description'. ICDM is an(More)
Legacy system data models can interoperate only if their syntactic and semantic differences are resolved. To address this problem, we have developed the Intelligent Mapping Toolkit (IMT), which enables mixed-initiative mapping of meta-data and instances between relational data models. IMT employs a distributed multi-agent architecture so that, unlike many(More)
This paper provides a basic description of the concept of an ontology. It then describes how ontologies are structured and employed in the context of interfaces between software based information systems. This usage is discussed in the context of three successive levels of semantic interoperability between two example systems. The paper goes on to suggest(More)
Traditional approaches to building intelligent information systems employ an ontology to define a representational structure for the data and information of interest within the target domain of the system. At runtime, the ontology provides a constrained template for the creation of the individual objects and relationships that together define the state of(More)
This report provides an overview description of the Toolkit for Information Representation and Agent Collaboration (TIRAC™) software framework for the development of intelligent decision-support applications. More technical descriptions of TIRAC™ are contained in a companion CDM Technical Report (CDM-19-03) entitled: 'The TIRAC™ Development Toolkit:(More)
Interoperability requires the resolution of syntactic and semantic variations among system data models. To address this problem, we developed the Intelligent Mapping Toolkit (IMT), which employs a distributed multi-agent architecture to enable the mixed-initiative mapping of metadata and instances. This architecture includes a novel federation of(More)
This paper serves as a layman's introduction to similarity assessment techniques, their distinction from contemporary computing paradigms, and their real-world applications. The following content derives from the experience gained by the authors in applying similarity assessment techniques to resolve the real-world problems of CDM customers, in particular(More)
Traditional approaches to building intelligent information systems employ an object model to define a representational structure for the information of interest within the target domain of the system. At runtime, the model provides a constrained template for the creation of the individual object instances and relationships that together define the state of(More)
This report describes work performed by CDM Technologies Inc. on subcontract to sponsorship of the Office of Naval Research (ONR). The principal aim of the SILS (Shipboard Integration of Logistics Systems) project is to provide a decision-support capability for Navy ships that integrates shipboard logistical and tactical systems within a near real-time,(More)
