Frederic Font, Sergio Oramas, György Fazekas, Xavier Serra
2014 International Semantic Web Conference  
In this paper we describe preliminary research around the idea of extending tagging ontologies by incorporating some domain specific class definitions and relations.  ...  We illustrate our idea with a particular use case where a tag recommendation system is driven by such an ontology.  ...  Conclusions In this paper we have shown some preliminary research on extending current tagging ontologies with structured knowledge specific to the domain of application of a tagging system.  ...

Augmenting Lightweight Domain Ontologies with Social Evidence Sources

Albert Weichselbraun, Gerhard Wohlgenannt, Arno Scharl

Taxonomy-Driven Ontology Design

Heather Hedden
2022 Zenodo  
Taxonomies can be semantically enriched to become ontologies with the addition of a high-level ontology model. This bottom-up approach leverages existing taxonomies.  ...  Taxonomies and ontologies are often merged. Ontologists might look upon taxonomies as the extension of ontologies to include hierarchies of subclasses and/or all instances of classes.  ...  define a domain ontology. ▸ A domain ontology may also be extended or applied to specific instances.  ...

TagSorting: A Tagging Environment for Collaboratively Building Ontologies [chapter]

Leyla Jael García-Castro, Martin Hepp, Alexander García
2010 Lecture Notes in Computer Science  
In this paper we argue that the potential of the social process of assigning, finding, and relating symbols in collaborative tagging scenarios is currently underexploited and can be increased by extending  ...  the meta-model and using this extension to support the emergence of structured knowledge, e.g. semantic knowledge representations.  ...  The Meaning-of-a-tag ontology (MOAT) extends Newman's ontology and provides a way for users to attach meanings (M) to their tags; a meaning relies on a resource and is part of the tagging (TA).  ...

On the Use of Ontologies for Search in a Collaborative System for Architectural Images [chapter]

Marisol Solis, Renata Wassermann, Vânia M.A. Lima
2016 Knowledge Organization for a Sustainable World: Challenges and Perspectives for Cultural, Scientific, and Technological Sharing in a Connected Society  
We concluded that the Ontology can be used as a conceptual basis to relate the represented knowledge with computational processes such as, for example, information retrieval in a collaborative system,  ...  In this work, we have proposed an ontology for the Arquigrafia, a social network for sharing architectural images, based on a controlled vocabulary of architectural domain and tags created by users.  ...  In the area of Knowledge Representation, ontology was defined by Gruber (1993, 199) as "an explicit specification of a conceptualization", that is, a description of concepts of a domain and relationships  ...

Development of a Framework to Understand Tables in Engineering Specification Documents

Valentin Agossou, Hyo-Won Suh, Heejung Lee, Jae Hyun Lee
2020 Applied Sciences  
It is assumed a domain ontology is given, and it is extended with new concepts and relationships extracted from tables. We illustrated how each step performed with engineering table examples.  ...  The framework consists of three steps: (1) Identifying minimal tables, (2) classifying cells, and (3) extending a domain knowledge map.  ...  with rule-based approach to extend a domain ontology.  ...

Elicitation synergy of extracting conceptual tags and hierarchies in textual document

Yu-Liang Chi
2007 Expert systems with applications  
Additionally, this elicitation synergy is especially useful for ontology editors who lack reference models of a working domain and who encounter textual corpus as major knowledge sources.  ...  This study develops an ontology building process for extracting conceptual tags and hierarchies in textual corpus.  ...  Thus, the objectives of this study include: (1) Recognizing terminologies based on textual corpus of specific domains; (2) Identifying unambiguous tag name of concept based on terminologies; and (3) Discovering  ...

Construct Primary Education Semantic Ontology Library Based Mind Mapping

Dong-Hong Hu, Xue-Jun Yu, T. Gong, T. Yang, J. Xu
2016 ITM Web of Conferences  
This paper proposed a solution based on cluster structure derived from mind mapping by providing logical description of the ontologies to precisely define semantics; Meanwhile, tags were adapted to associate  ...  different ontologies to form ontology library.  ...  Quickly increasing vocabulary, the development of semantic technology and subdivision of primary education domain ontology type ask us to construct semantic ontology with considering to extend the ontology  ...

Jürgen Vöhringer, Doris Gälle, Günther Fliedl, Christian Kop, Mykola Bazhenov
2010 International Journal of Computational Linguistics and Applications  
In the requirements engineering domain finegranulated domain ontologies are needed; therefore the suitability of both hand-knitted and automatically generated gap-afflicted ontologies for developing applications  ...  Nowadays ontology creation is on the one hand very often hand-knitted and thus arbitrary.  ...  for supporting ontology creation and fine-tune ontologies through step-by-step integration of domain knowledge.  ...

An ontological metamodeling framework for semantic simulation model engineering

Lei Yonglin, Zhu Zhi, Li Qun
2020 Journal of Systems Engineering and Electronics  
Recently, the ontological metamodel plays an increasingly important role to specify systems in two forms: ontology and metamodel.  ...  Ontology is a descriptive model representing reality by a set of concepts, their interrelations, and constraints.  ...  The top level ontology describes a set of domain specific concepts, relationships and tags for the CESS domain.  ...

Using the Ontology Maturing Process Model for Searching, Managing and Retrieving Resources with Semantic Technologies [chapter]

Simone Braun, Andreas Schmidt, Andreas Walter, Valentin Zacharias
2008 Lecture Notes in Computer Science  
They enhance these systems through background knowledge stored in ontologies. However, in most cases, resources in these systems change very fast.  ...  In consequence, they require a dynamic and agile change of underlying ontologies. Also, the formality of these ontologies must fit the users needs and capabilities and must be appropriate and usable.  ...  annotate it, e.g. with the specific plastic.  ...
