  • New requests for permissions/Bot: Balyozbot. Tasks:

1. Import sitelinks, labels, descriptions from ku wikipedia pages which use the template w:ku:Template:Înterwîkî etîket û danasîn. (There are over 1800 articles that use this template waiting to be connected to Wikidata at the moment.)
2. Add sitelinks to kuwiktionary / kuwikipedia categories / create an item for the category if necessary. I have been doing this manually for quite some time using Quickstatements but since I need to get permission for the first task, I will be handling them using a bot as well.

  • Papers: Increasing Coverage and Precision of Textual Information in Multilingual Knowledge Graphs by (Conia et al, 2023) --> This paper introduces a novel task of automatic Knowledge Graph Enhancement (KGE) to bridge the gap in the quantity and quality of textual information between English and non-English languages in Wikidata. It presents M-NTA, an unsupervised approach that combines Machine Translation, Web Search, and Large Language Models to generate high-quality textual information, and studies its impact on Entity Linking, Knowledge Graph Completion, and Question Answering tasks.

    • Wikidata, Wikisource and Wiktionary: Wikisource for DH (WiSe 2023) --> The lecture "Fundamentals and application-oriented methods of the Digital Humanities" by Kay-Michael Würzner is designed as a series of lectures in which teachers in the "Digital Humanities" course present their fields of work and key topics and present them for discussion.
    • Empowering Open-Source Generative AI by Integrating the Wikidata knowledge graph --> Generative AI has changed the information ecosystem, and open-source knowledge graphs like Wikidata can become invaluable assets, propelling a myriad of applications forward. Jonathan Fraine & Lydia Pintscher present the practical integration of Wikidata's open-source, open-access knowledge graph to empower Generative AI applications. Harnessing the real-time updated, structured data encapsulated within Wikidata, they explore automated content creation, data augmentation, and semantic analysis, underpinning the generative paradigms. Through a blend of theoretical insights and real-world applications, they elucidate how to leverage Wikidata to elevate generative AI applications, breaking down existing data silos, and fostering a collaborative ecosystem within our global community of developers and contributors.

• Tool of the week
  • Cersei - is a tool designed for importing or scraping data from various third-party sources, using source-specific Python code. It can use a "headless browser" to scrape complicated websites that rely on eg JavaScript to navigate. It can therefore access data sources that can not be accessed via eg Mix'n'match. The data from sources can be updated regularly, either for everything, or just changed entries (if the source has a "recent changes" equivalent).
  • Wikidata:Zotero/Cita - is a Wikidata addon for Zotero that adds citations (i.e., what other items an item cites) metadata support to this open source reference management software, using cites work (P2860) information available from Wikidata, and enabling users to easily contribute missing data.
