The deadline for the Semantic Web Journal Special Issue on Wikidata was extended to 14.02. More information can be found here: https://www.semantic-web-journal.net/blog/call-papers-special-issue-wikidat… We are looking forward to your contributions! The full call for papers is below. Call for papers: Semantic Web Journal Special Issue on Wikidata: Construction, Evaluation and Applications Wikidata is an openly available knowledge base, hosted by the Wikimedia Foundation. It can be accessed and edited by both humans and machines and acts as a common structured-data repository for several Wikimedia projects, including Wikipedia, Wiktionary, and Wikisource. It is used in a variety of semantic web applications by researchers and practitioners alike. In recent years, we have seen an increase in the number of publications around Wikidata. While there are several dedicated venues for the broader Wikidata community to meet, none of them focuses on publishing comprehensive, peer-reviewed research. This special issue fills this gap - we hope to provide a forum to build this fledgling scientific community and promote novel work and resources that support it. The special issue seeks original contributions and extended conference papers that address the opportunities and challenges of creating, contributing to, and using the global, collaborative, open-domain, multilingual knowledge graph Wikidata. Topics Topics of submissions include, but are not limited to: - Data quality and vandalism detection in Wikidata - Referencing in Wikidata - Anomaly, bias, or novelty detection in Wikidata - Algorithms for aligning Wikidata with other structured or semi-structured resources - Representation, Semantic Annotation, Enhancement and Enrichments using Wikidata - Semantic Parsing and Question Answering using Wikidata - The Semantic Web and Wikidata - Community interaction in Wikidata - Multilingual data in Wikidata and its reuse - Data quality in Wikidata: Approaches for problem detection, evaluation and improvement - Tools, bots, and datasets for improving or evaluating Wikidata - Participation, diversity, and inclusivity aspects in the Wikidata ecosystem - Human-bot interaction - Managing knowledge evolution in Wikidata - Abstract Wikipedia - Wikidata in NLP applications Deadline - Submission deadline: 14 February 2023 (extended!). Papers submitted before the deadline will be reviewed upon receipt. Author Guidelines Submissions shall be made through the Semantic Web journal website at http://www.semantic-web-journal.net.
