发现维基数据类别层级存在混乱并提出修复方案
Class Order Disorder in Wikidata and First Fixes
- 通过SPARQL查询检测类别层级违规与可疑信息
- 手动修正后验证问题减少，证明修改有效
- 适合数据质量研究者与维基社区维护者参考
维基数据拥有包含多级类别的大型本体，长期存在类别层级违反规范及可疑信息的问题。本文通过针对维基数据执行SPARQL查询，评估了多种违规类型及可疑信息的普遍性，并进行了分析。部分问题通过人工修改得以修正，重新运行查询显示修改后结果改善。文章提出改进建议，可通过增强工具或提升维基数据社区参与来解决这些问题。
原文摘要 · Abstract (English)
Wikidata has a large ontology with classes at several orders. The Wikidata ontology has long been known to have violations of class order and information related to class order that appears suspect. SPARQL queries were evaluated against Wikidata to determine the prevalence of several kinds of violations and suspect information and the results analyzed. Some changes were manually made to Wikidata to remove some of these results and the queries rerun, showing the effect of the changes. Suggestions are provided on how the problems uncovered might be addressed, either though better tooling or involvement of the Wikidata community.
