We have developed an OWL ontology for the geologic timescale, derived from a Unified Modeling Language (UML) model that formalized the practice of the International Commission for Stratigraphy (ICS) (Cox and Richard 2005). The UML model followed the ISO/TC 211 modeling conventions, and was the basis for an XML implementation that was integrated into GeoSciML 3.0. The OWL ontology is derived using rules for generating OWL ontologies from ISO-conformant UML models, as provided in a (draft… 

A Chinese Geological Time Scale Ontology for geodata discovery

The design and construction of the Chinese Geological Time Scale Ontology (CGTO) regarding the temporal features within datasets is studied and some future works are discussed in order to make CGTO more applicable.

The Linked Earth Ontology : A Modular , Extensible Representation of Open Paleoclimate Data

Paleoclimatology is a highly integrative discipline, involving researchers with often disjunct expertise in the field sciences, geochemistry, data analysis and numerical modeling. The resulting

Time and Geology in Geographic Information Systems: Some Formalism for Describing Temporal Events

Since first concepts and prototypes for integrated geographic information systems (GIS) have been designed, incorporation of time has always been a matter of research, philosophical debate, and

A pilot study that uses a domain specific knowledge base and data visualization techniques to leverage the functionality of geoscience data services in the Web of Data and leverages the functionalities of existing standards into a new level forGeoscience applications.

A Formal Representation of the Semantics of Structural Geological Models

A structural geological model describes the structure of subsurface and plays an important role in the exploration of mineral and petroleum resources. Despite the widespread use of three-dimensional

Tagging of temporal expressions and geological features in scientific articles

This work investigates tagging figure and table captions in scientific articles from geology to support visualization of research findings on maps and time-lines and found that the poor performance of the baseline approach is mainly due to a lack of coverage in the gazetteers.

OWL ontologies for the ISO/OGC model for Observations, and for other standard geographic information schemas (geometry, time, metadata) upon which it depends, have been developed.

A formal model for the geologic time scale and global stratotype section and point, compatible with geospatial information transfer standards

The geologic time scale is a complex data structure composed of abstract elements that represent time intervals and instants and their relationships with specific concrete representations in the

Recent progress on geologic time ontologies and considerations for future works

A review of the recent progress on geologic time ontologies, discuss further improvements, and make recommendations for other geoscience ontology works.

Geological time formalization: an improved formal model for describing time successions and their correlation

This work defines two ontologies for geological time description and for geological dating and extends the GeoSciML model, so that it becomes possible to fully use the Allen rules for operating time correlations between any couple of time scales or stratigraphic successions.

Geologic time scale 2004

An international team of over 40 stratigraphic experts, many actively involved in the International Commission of Stratigraphy (ICS), have helped to build the most up-to-date international

The ICS International Chronostratigraphic Chart

The International Commission on Stratigraphy (ICS) has a long tradition of producing international charts that communicate higher-order divisions of geological time and actual knowledge on the
