Link Prediction using Numerical Weights for Knowledge Graph Completion within the Scholarly Domain

2021-01-31T12:14:11+01:00

Abstract Knowledge graphs (KGs) are widely used for modeling scholarly communication, informing scientometric analysis, and supporting a variety of intelligent services to explore the literature and predict research dynamics. However, they often suffer from [...]

5* Knowledge Graph Embeddings with Projective Transformations

2021-01-31T12:17:54+01:00

Abstract Performing link prediction using knowledge graph embedding (KGE) models is a popular approach for knowledge graph completion. Such link predictions are performed by measuring the likelihood of links in the graph via a [...]

Adaptive Margin Ranking Loss for Knowledge Graph Embeddings via a Correntropy Objective Function

2021-01-31T12:18:45+01:00

Abstract Translation-based embedding models have gained significant attention in link prediction tasks for knowledge graphs. TransE is the primary model among translation-based embeddings and is well-known for its low complexity and high efficiency. Therefore, [...]

Unveiling scholarly communities over knowledge graphs

2020-12-13T23:04:41+01:00

Abstract Knowledge graphs represent the meaning of properties of real-world entities and relationships among them in a natural way. Exploiting semantics encoded in knowledge graphs enables the implementation of knowledge-driven tasks such as semantic [...]

SemSur: a core ontology for the semantic representation of research findings

2020-12-13T23:10:43+01:00

Abstract The way how research is communicated using text publications has not changed much over the past decades. We have the vision that ultimately researchers will work on a common structured knowledge base comprising [...]

Towards a knowledge graph representing research findings by semantifying survey articles

2020-12-13T23:20:11+01:00

Abstract Despite significant advances in technology, the way how research is done and especially communicated has not changed much. We have the vision that ultimately researchers will work on a common knowledge base comprising [...]

OpenResearch: Collaborative Management of Scholarly Communication Metadata

2020-12-13T23:56:38+01:00

Abstract Scholars often need to search for matching, high-profile scientific events to publish their research results. Information about topical focus and quality of events is not made sufficiently explicit in the existing communication channels [...]
