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.

Applying KAoS Services to Ensure Policy Compliance for Semantic Web Services Workflow Composition and Enactment

Paper on applying KAoS services to ensure policy compliance in semantic web services workflow composition and enactment.

This paper explores the application of KAoS services to ensure policy compliance in semantic web services. The authors investigate how KAoS can be used to manage policies and ensure that they are enforced during the composition and enactment of workflows. The paper discusses the benefits and challenges of using KAoS for this purpose, including its ability to provide a flexible and scalable approach to policy management.
