Andrea Calì, Thomas Lukasiewicz
2008 Lecture Notes in Computer Science  
We propose an approach to probabilistic data integration for the Semantic Web that is based on probabilistic description logic programs, where probabilistic uncertainty is used to handle inconsistencies  ...  It is inspired by recent works on probabilistic data integration in the database and web community [5, 2] .  ...  Overview Towards sophisticated reasoning capabilities for the Semantic Web, the work [4] has introduced probabilistic description logic programs (or probabilistic dl-programs), which combine description  ...

Efficiently finding web services using a clustering semantic approach

2008 Proceedings of the 2008 international workshop on Context enabled source and service selection, integration and adaptation organized with the 17th International World Wide Web Conference (WWW 2008) - CSSSIA '08  
Inspired by the success of partitioning approach used in the database design, we used a novel clustering semantic algorithm to eliminate irrelevant services with respect to a query.  ...  Then we utilized Probabilistic Latent Semantic Analysis (PLSA), a machine learning method, to capture the semantics hidden behind the words in a query, and the descriptions in the services, so that service  ...  Data Processing The goal of the data processing is to transform raw Web service information into an appropriate data format suitable for model learning.  ...

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  
Among these is the need for semantic interoperability among systems with different internal data models and vocabularies.  ...  This paper proposes the use of probabilistic ontologies within a service-oriented architecture as a means to enable semantic interoperability in net-centric fusion systems.  ...  Figure 2 shows an example, taken from [11] , of a Bayesian network for integrating data from different sources into an integrated vegetation cover map, an important input into a CCM TDA.  ...
