Ontology-Driven Geographic Information Systems

by Frederico T. Fonseca, Max J. Egenhofer , 1999
"... This paper introduces a geographic information system architecture based on ontologies. Ontology plays a central role in the definition of all aspects and components of an information system in the so-called ontology-driven information systems. The system presented here uses a container of interoper ..."

Linked Data -- The story so far

by Christian Bizer, et al.
"... The term Linked Data refers to a set of best practices for publishing and connecting structured data on the Web. These best practices have been adopted by an increasing number of data providers over the last three years, leading to the creation of a global data space containing billions of assertion ..."

to exploit the Web of Data, and map out a research agenda for the Linked Data community as it moves forward.

navigating knowledge with ontology-driven

by Yannis Kalfoglou, Yannis Kalfoglou, John Domingue, John Domingue, Leslie Carr, Leslie Carr, Enrico Motta, Enrico Motta, Maria Vargas-vera, Maria Vargas-vera, Simon Buckingham Shum, Simon Buckingham Shum
"... Nowadays, many distinct communities are researching on technologies for knowledge capturing, modelling, and navigation. Moreover, advances in Internet technology makes it possible to perform most of these tasks on heterogeneous and distributed environments such as the Web. These advances though, ha ..."

. We describe such an integration effort in this paper. Our domain is a Web-based news repository and we aimed to provide personalised ontology-driven services on the top of it. We used knowledge capturing technologies to populate the underlying ontologies, knowledge modelling techniques to provide

Formal Ontology and Information Systems

by Nicola Guarino , 1998
"... Research on ontology is becoming increasingly widespread in the computer science community, and its importance is being recognized in a multiplicity of research fields and application areas, including knowledge engineering, database design and integration, information retrieval and extraction. We sh ..."

Models and issues in data stream systems

by Brian Babcock, Shivnath Babu, Mayur Datar, Rajeev Motwani, Jennifer Widom - IN PODS , 2002
"... In this overview paper we motivate the need for and research issues arising from a new model of data processing. In this model, data does not take the form of persistent relations, but rather arrives in multiple, continuous, rapid, time-varying data streams. In addition to reviewing past work releva ..."
