Construction of Knowledge Graphs: State and Challenges

A research paper on the construction and updating of knowledge graphs.

The authors discuss graph models, requirements for KG construction pipelines, and necessary steps to build high-quality KGs. They evaluate the state-of-the-art and identify areas in need of further research. The paper provides an overview of the individual steps involved in creating and updating KGs from unstructured and structured data sources.

Ontology Repositories and Semantic Artefact Catalogues with OntoPortal Technology

A paper on the OntoPortal Alliance consortium's platforms for ontology management.

The OntoPortal Alliance consortium provides common platforms for receiving, hosting, serving, aligning, and enabling reuse of ontologies and semantic artefacts.,These platforms make ontologies FAIR (Findable, Accessible, Interoperable, Reusable).,They address the growing need for governance of exploding number of semantic artefacts in science.

DCSO: towards an ontology for machine-actionable data management plans

Paper proposing the DMP Common Standard Ontology (DCSO) as a serialisation of the DCS core concepts.

The authors propose the DMP Common Standard Ontology (DCSO) to represent Data Management Plans as machine-actionable artefacts. The ontology is based on the Research Data Alliance DMP Common Standard and aims to provide a standardised way to describe controlled vocabularies. The paper reports on a community effort to create the DCSO, which can become a suitable candidate for a reference serialisation of the DMP Common Standard.

Enabling ad-hoc reuse of private data repositories through schema extraction

A paper proposing a configurable and automated schema extraction approach for RDF triple stores.

The authors present an approach to extract and publish data schemas from private repositories, enabling SPARQL query formulation without direct access. Evaluation with four datasets shows the effectiveness of this method in deriving concise and task-relevant schemas. This approach can facilitate reuse of data from previously inaccessible sources.

RDF graph validation using rule-based reasoning

Paper proposing an alternative validation approach for RDF graphs using rule-based reasoning.

The paper presents a new validation method that uses rule-based reasoning to validate RDF graphs. It compares to existing approaches and provides a formal ground and practical implementation called Validatrr, which is based on N3Logic and the EYE reasoner. The proposed approach better explains the root cause of violations and returns an accurate number of violations.

Completeness and consistency analysis for evolving knowledge bases

This paper presents an analysis on completeness and consistency in evolving knowledge bases.

The authors propose a framework to analyze the completeness and consistency of evolving knowledge bases. They introduce metrics to measure these aspects and apply them to several case studies. The results demonstrate the effectiveness of their approach in identifying issues with knowledge base evolution.

Multilingual Knowledge Graph Embeddings for Cross-lingual Knowledge Alignment

A translation-based model for multilingual knowledge graph embeddings.

The paper proposes MTransE, a model that provides transitions for each embedding vector to its cross-lingual counterparts in other spaces. It can be trained on partially aligned graphs and preserves the key properties of monolingual embeddings. The experiments show promising results on cross-lingual entity matching and triple-wise alignment verification.
