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… Expand
Semantics-informed geological maps: Conceptual modeling and knowledge encoding
TLDR
A novel, semantics-informed geologic mapping process, whose application domain is the production of a synthetic geologic map of a large administrative region, and a conceptual model that aims at building a digital encoding of several domains of geologic knowledge, in order to support the interoperability of the sources. Expand
Ontology-driven representation of knowledge for geological maps
TLDR
An ontology-driven method for the interpretation and the encoding of the map data that employs shared vocabularies and resources encoded through ontologies in order to prevent the use of ambiguous terms is introduced. Expand
A Chinese Geological Time Scale Ontology for geodata discovery
TLDR
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. Expand
Ontology-driven data integration and visualization for exploring regional geologic time and paleontological information
TLDR
An ontology-driven data integration and visualization pilot system for exploring information of regional geologic time, paleontology, and fundamental geology and shows that, to improve the compatibility between local and global geologic standards, bridge gaps between different data sources, and create smart geoscience data services, it is necessary to further extend and improve the existing geos science ontologies.

A new structure for representing and tracking version information in a deep time knowledge graph
TLDR
This work has reused the existing ontologies for geologic time scale and vocabularies for the International (Chrono)stratigraphic Chart (ISC) and proposed a new structure for version control and tracking of concepts, attributes and topological relationships in the deep time knowledge graph. Expand
Semantic modeling of plastic deformation of polycrystalline rock
TLDR
The first iteration of the Plastic Rock Deformation ontology is developed by modeling the semantics of a selected set of deformational processes and mechanisms that produce, reconfigure, displace, and/or consume the material components of inhomogeneous polycrystalline rocks. Expand
Tagging of temporal expressions and geological features in scientific articles
TLDR
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. Expand
