Ademar Jr. Crotti
2022 Zenodo  
But while the benefits of knowledge graphs have become clear, the road to their implementation has often been long and complex and success has relied on the involvement of seasoned knowledge graph experts  ...  For example, most ontology modeling tools available today target the ontology engineer, thus excluding domain experts and common business users from this process. https://www.knowledgegraph.tech/kgc-2022  ...  data is a time-consuming task, as data might come from different sources Pinpoint your information needs Model your domain Build the user experience Collaboratively define a knowledge model.  ...

1992 Artificial Intelligence in Medicine  
Acknowledgements The support of the Leverhulme Trust for the SDD project is gratefully acknowledged.  ...  The need for a diagnostic framework to support the explicit integration of background domain knowledge is certainly not specific to the domain of skeletal dysplasias.  ...  These examples use knowledge which is general radiological/clinical knowledge rather than knowledge specific to the domain of skeletal dysplasias.  ...

Relevant evidence acquisition and appraisal using knowledge-intensive queries

Muhammad Afzal, Sungyoung Lee
2016 2016 18th International Conference on Advanced Communication Technology (ICACT)  
The construction of knowledge-intensive query is based on the term expansion using domain model, name variants, and terminological variants.  ...  Information needs of the users have grown exponentially with the advent of advancements in information and communication technology.  ...  The limitation of this strategy is the dependency on domain experts, however, it can be resolved by knowledge of domain.  ...

Web Data Knowledge Extraction [article]

Juan M. Tirado, Ovidiu Serban, Qiang Guo, Eiko Yoneki
2016 arXiv   pre-print
The figure of the expert is still needed in many situations where developers do not have the correct background knowledge.  ...  Our methodology differs from similar solutions in its expert-driven design. This design, makes it possible for subject-matter expert to drive the knowledge extraction for a given set of documents.  ...  The research is funded by H2020 DIGIWHIST project (645852). We would like to thank Christopher Ré in Stanford University for valuable input and discussion and NLP group in University of Cambridge.  ...

Semantics and knowledge organization

Birger Hjørland
2007 Annual Review of Information Science and Technology  
Information scientists may feel safer if they rely on "experts" rather than documents, but relevant documents are written by experts and are equally valid sources, if not more so.  ...  In other words, semantic structures in IS cannot be established simply by the study of natural languages: this also requires domain-specific knowledge.  ...  Appendix Some important kinds of semantic relations that have been presented in the literature:  ...
