Thomas Mandl, Christa Womser-Hacker
2001 Lecture Notes in Computer Science  
This article reports some experiments for the mapping between different ontologies and shows further that fusion methods which have been successfully applied to ad-hoc information retrieval can also be  ...  Automatic methods for mappings between different ontologies are necessary to ensure successful retrieval of information stored in virtual digital libraries.  ...  For example, an optimal learning scheme can be identified for a mapping from a group of terms to a another group of terms in the target ontology.  ...

2003 Sixth International Conference of Information Fusion, 2003. Proceedings of the  
To this end, we propose a methodological approach and a flexible environment for ontology management that enables the building of extensible ontologies, and the mapping from ontologies to information sources  ...  In this paper, we discuss the role of ontologies to facilitate information fusion from heterogeneous data and knowledge sources in support of high-level information fusion processes.  ...  As ontologies promote knowledge reuse and sharing, we should benefit from previous work conducted in related domains, for example in the military planning domain.  ...

Scaling Up Question-Answering to Linked Data [chapter]

Vanessa Lopez, Andriy Nikolov, Marta Sabou, Victoria Uren, Enrico Motta, Mathieu d'Aquin
2010 Lecture Notes in Computer Science  
As such, we go one step beyond the state of the art on end-users interfaces for Linked Data by introducing mapping and fusion techniques needed to translate a user query by means of multiple sources.  ...  PowerAqua is an open multi-ontology Question Answering (QA) system for the Semantic Web (SW).  ...  Nonetheless, to find a trade-off between the complexity of the querying process and the amount of data it can use and integrate is still an open problem for ontology-based approaches.  ...

Towards Data Fusion in a Multi-ontology Environment

Andriy Nikolov, Victoria S. Uren, Enrico Motta
2009 The Web Conference  
In this paper we discuss how ontology schema mismatches influence data-level alignment based on our first experience with implementing a data fusion tool for a multiontology environment.  ...  Given that datasets are often structured using different ontologies, automatic schema-matching techniques have to be utilized before proceeding with data-level alignment.  ...  Based on our experience, we can outline several directions for assisting data fusion in the presence of schema heterogeneity.  ...

Probabilistic ontology for net-centric fusion

Kathryn Blackmond Laskey, Paulo C.G. da Costa, Edward J. Wright, Kenneth J. Laskey
2007 2007 10th International Conference on Information Fusion  
Ontologies are seen as a key enabling technology for semantic interoperability.  ...  Although information fusion by nature involves reasoning under uncertainty, traditional ontology formalisms provide no principled means of reasoning under uncertainty.  ...  Figure 8 shows a simplified scheme for net centric fusion using probabilistic semantic mapping in which a commander needs to choose between avenue of approach Alpha and its alternative Bravo from figures  ...

Baofeng Guo, Yi Wang, Paul Smart, Nigel Shadbolt, Mark S. Nixon, T. Raju Damarla
2007 MILCOM 2007 - IEEE Military Communications Conference  
Ontologies are most suited to this task as they allow for rich representation of data structure; some approaches include probabilistic representation.  ...  In the next Section we describe the current stock of approaches to (conventional) data fusion, including the JDL data fusion model for completeness.  ...  The two most important uses of mappings required for information integration are mappings between ontologies and the information they describe and mapping between different ontologies used in a system.  ...
