The PROMPT Suite: Interactive Tools for Ontology Merging and Mapping
- International Journal of Human-Computer Studies
, 2003
"... Researchers in the ontology-design field have developed the content for ontologies in many domain areas. This distributed nature of ontology development has led to a large number of ontologies covering overlapping domains. In order for these ontologies to be reused, they first need to be merged o ..."

or aligned to one another. We developed a suite of tools for managing multiple ontologies. These suite provides users with a uniform framework for comparing, aligning, and merging ontologies, maintaining versions, translating between di#erent formalisms. Two of the tools in the suite support semi
Ontology-Based Integration of Information - A Survey of Existing Approaches
, 2001
"... We review the use on ontologies for the integration of heterogeneous information sources. Based on an in-depth evaluation of existing approaches to this problem we discuss how ontologies are used to support the integration task. We evaluate and compare the languages used to represent the ontologies ..."

and the use of mappings between ontologies as well as to connect ontologies with information sources. We also enquire into ontology engineering methods and tools used to develop ontologies for information integration. Based on the results of our analysis we summarize the state-of-the-art in ontology
Geometric diffusions as a tool for harmonic analysis and structure definition of data: Diffusion maps
- Proceedings of the National Academy of Sciences
, 2005
"... of contexts of data analysis, such as spectral graph theory, manifold learning, nonlinear principal components and kernel methods. We augment these approaches by showing that the diffusion distance is a key intrinsic geometric quantity linking spectral theory of the Markov process, Laplace operators ..."

This opens the door to the application of methods from numerical analysis and signal processing to the analysis of functions and transformations of the data. Abstract. We provide a framework for structural multiscale geometric
Supporting Ontological Analysis of Taxonomic Relationships
, 2001
"... Taxonomies are an important part of conceptual modeling. They provide substantial structural information, and are typically the key elements in integration efforts, however there has been little guidance as to what makes a proper taxonomy. We have adopted several notions from the philosophical pract ..."

These tools, identity, essence, unity, and dependence, provide a solid logical framework within which the properties that form a taxonomy can be analyzed. This analysis helps make intended meaning more explicit, improving human
Framework for Ontology Alignment and Mapping
"... Semantic alignment between ontologies is a necessary precondition to establish interoperability between agents or services using different individual ontologies. This cannot be done manually beyond a certain complexity and size of ontologies. The core contribution in this article is the Framework fo ..."

Ontology of Integration and Integration of Ontologies
- PROCS. OF THE 2001 DESCRIPTION LOGIC WORKSHOP (DL 2001
, 2001
"... One of the basic problems in the development of techniques for the semantic web is the integration of ontologies. In this paper we deal with a situation where we have various local ontologies, developed independently from each other, and we are required to build an integrated, global ontology as a m ..."

A graph-oriented model for articulation of ontology interdependencies
- In Proceedings, 7th International Conference on Extending Database Technology
, 2000
"... Abstract: Ontologies are knowledge structures to explicate the contents, essential properties, and relationships between terms in a knowledge source. Many sources are now accessible with associated ontologies. Most prior work on use of ontologies relies on the construction of a single global ontolog ..."

The rules are generated using a semi-automatic articulation tool with the help of a domain expert. To make
Linking Lexicons and Ontologies: Mapping WordNet to the Suggested Upper Merged Ontology

An Ontology-Driven Framework for Data Transformation in Scientific Workflows

In addition, a registration mapping can be defined to relate input and output structural types to their corresponding semantic types. Using
