A domain-independent process for automatic ontology population from text

Carla Faria, Ivo Serra, Rosario Girardi, C. Faria, more

Science of Computer Programming > 2014 > 95 > Part 1 > 26-43

Ontology Population looks for instantiating the constituent elements of an ontology, like properties and non-taxonomic relationships. Manual population by domain experts and knowledge engineers is an expensive and time consuming task. Fast ontology population is critical for the success of knowledge-based applications. Thus, automatic or semi-automatic approaches are needed. This work proposes a generic...

A novel semantic representation approach for web documents using deep entity linking and multidocument support

Giridhar Urkude, Manju Pandey

International Journal of Communication Systems > 35 > 8 > n/a - n/a

Representing semantic web information in the form of existing formats like extensible mark‐up language (XML), resource description framework (RDF) or web ontology language (OWL) is limited by the inability to maintain intradocument relationships between different semantic entities. Moreover, these standards are built for generic data representation and thus do not have inherent support for the semantic...

IoT‐based platform for environment data sharing in smart cities

Jesús Noel Suárez Rubí, Paulo Roberto Gondim

International Journal of Communication Systems > 34 > 2 > n/a - n/a

The technological development and dissemination of IoT equipment have led to large volumes of environmental data which, in some cases, are incomplete, follow different formats of representation, and even have different semantic approaches. All such aspects and the heterogeneity of different IoT components (e.g., network interfaces, communication protocols, data structure, and data semantics) have...

A spatio-semantic approach to reasoning about agricultural processes

Henning Deeken, Thomas Wiemann, Joachim Hertzberg

Applied Intelligence > 2019 > 49 > 11 > 3821-3833

Digitization of agricultural processes is advancing fast as telemetry data from the involved machines becomes more and more available. Current approaches commonly have a machine-centric view that does not account for machine-machine or machine-environment relations. In this paper we demonstrate how to model such relations in the generic semantic mapping framework SEMAP. We describe how SEMAP’s core...
