A probabilistic Framework for Information Integration and Retrieval on the Semantic Web
نویسندگان
چکیده
We present a framework for probabilistic Information Processing on the Semantic Web that is capable of representing ontologies, deductive databases, uncertain mappings between them, results of statistical instance classification and ontology learning. Our framework is built on a knowledge representation formalism called Bayesian Description Logic Programs because it is a probabilistic extension of Description Logic Programms and a fragment of Bayesian Logic Programs. We show in this paper how to perform information integration and retrieval within our framework by means of integrated reasoning.

Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملDealing with Uncertainty in the Semantic Web
Standardizing the Semantic Web is still an ongoing process. For some aspects, the standardization seems to have completed. For example, the syntax layer, the RDF data model layer and the RDFS and OWL semantic extensions have proven to fulfill their purpose in real world applications. Other aspects, while necessary to realize the greater ideal of the Semantic Web, are yet to be standardized. One...
