Intro

Publication KG ontology is a custom ontology that helps to describe the knowledge graph about research papers. During the creation of the Publication KG we encountered relations that we wanted to describe but that were not possible to model with encountered publishing ontologies. Therefore, we created a new ontology which we present on this page.

• RelatedObjectRelation - a helper class used to better describe a relation between a given research paper and another object e.g. another paper or a concept.
• hasRelated - property representing a relation between a research paper and another object. Points to RelatedObjectRelation class. Other properties are then used to further describe the relation.

Publication embedding

• hasWordEmbedding - property representing the embedded vector of the title and abstract of a given research paper.

Relation with topics

• RelatedTopicRelation - a helper class to better describe the relation between a given research paper and a relevant concept.
• hasRelatedTopic - property specifying a list of topics or concepts that are related to the given research paper.
• hasRelationTarget - property pointing to the target of the relation. An object that is associated with a given research paper.
• hasRelationScore - property quantifying how much the target of the relationship is related to a given research paper.

Relation with other papers

• RelatedPaperRelation - a helper class to better describe the relationship between two research papers.
• hasRelatedPaper - property indicating that a research paper has similar content to another research paper, determined by the cosine similarity of their embeddings.
