Theory and Practice of Relational-to-RDF Temporal Data Exchange and Query Answering

ACM JOURNAL OF DATA AND INFORMATION QUALITY, 15(2).

By: J. Ao n, Z. Cheng *, R. Chirkova n & P. Kolaitis *

author keywords: Data-intensive sciences and databases; theory of temporal databases; information quality in temporal data exchange; RDF / RDFS / SPARQL
TL;DR: A general framework that formalizes the relational-to-RDF temporal data-exchange problem and proves correctness of the information output by the algorithms is developed and also reports on the algorithm implementation and experimental results for two application domains.

Trustworthy Knowledge Graph Population From Texts for Domain Query Answering

2021 IEEE INTERNATIONAL CONFERENCE ON BIG DATA (BIG DATA), pp. 4590–4599.

By: J. Ao n, S. Dinakaran n, H. Yang n, D. Wright n  & R. Chirkova n

Contributors: J. Ao n, S. Dinakaran n, H. Yang n, D. Wright n  & R. Chirkova n

author keywords: Text data; populating knowledge graphs; ontology-based information extraction; feature engineering
TL;DR: A scalable domain-independent text-to-KG approach that adapts to specific domains by using domain ontologies, without having to consult external triple repositories is introduced, which builds on the power of neural-based learning models and leverages feature engineering to distinguish ontology-aligned data from generic data in the source texts.
