Semantic Wiki Search
Semantic Wiki Search Peter Haase1, Daniel Herzig1,, Mark Musen2,andThanhTran1 1 Institute AIFB, Universit¨at Karlsruhe (TH), Germany {pha,dahe,dtr}@aifb.uni-karlsruhe.de 2 Stanford Center for Biomedical Informatics Research (BMIR) Stanford University, USA [email protected] Abstract. Semantic wikis extend wiki platforms with the ability to represent structured information in a machine-processable way. On top of the structured in- formation in the wiki, novel ways to search, browse, and present the wiki content become possible. However, while powerful query languages offer new opportuni- ties for semantic search, the syntax of formal query languages is not adequate for end users. In this work we present an approach to semantic search that combines the expressiveness and capabilities of structured queries with the simplicity of keyword interfaces and faceted search. Users articulate their information need in keywords, which are translated into structured, conjunctive queries. This transla- tion may result in multiple possible interpretations of the information need, which can then be selected and further refined by the user via facets. We have imple- mented this approach to semantic search as an extension to Semantic MediaWiki. The results of a user study in the SMW-based community portal semanticweb.org show the efficiency and effectiveness of the approach as well as its ease of use. 1 Introduction The availability of structured information on the Semantic Web enables new opportu- nities for information access. Search is no longer limited to matching keywords against documents, but instead complex information needs can be expressed in a structured way, with precise and structured answers as results [1,2,3]. -

Wiki-Reliability: a Large Scale Dataset for Content Reliability on Wikipedia
Wiki-Reliability: A Large Scale Dataset for Content Reliability on Wikipedia KayYen Wong∗ Miriam Redi Diego Saez-Trumper Outreachy Wikimedia Foundation Wikimedia Foundation Kuala Lumpur, Malaysia London, United Kingdom Barcelona, Spain [email protected] [email protected] [email protected] ABSTRACT Wikipedia is the largest online encyclopedia, used by algorithms and web users as a central hub of reliable information on the web. The quality and reliability of Wikipedia content is maintained by a community of volunteer editors. Machine learning and information retrieval algorithms could help scale up editors’ manual efforts around Wikipedia content reliability. However, there is a lack of large-scale data to support the development of such research. To fill this gap, in this paper, we propose Wiki-Reliability, the first dataset of English Wikipedia articles annotated with a wide set of content reliability issues. To build this dataset, we rely on Wikipedia “templates”. Tem- plates are tags used by expert Wikipedia editors to indicate con- Figure 1: Example of an English Wikipedia page with several tent issues, such as the presence of “non-neutral point of view” template messages describing reliability issues. or “contradictory articles”, and serve as a strong signal for detect- ing reliability issues in a revision. We select the 10 most popular 1 INTRODUCTION reliability-related templates on Wikipedia, and propose an effective method to label almost 1M samples of Wikipedia article revisions Wikipedia is one the largest and most widely used knowledge as positive or negative with respect to each template.

Chaudron: Extending DBpedia with measurement Julien Subercaze1 Univ Lyon, UJM-Saint-Etienne, CNRS Laboratoire Hubert Curien UMR 5516, F-42023, SAINT-ETIENNE, France [email protected] Abstract. Wikipedia is the largest collaborative encyclopedia and is used as the source for DBpedia, a central dataset of the LOD cloud. Wikipedia contains numerous numerical measures on the entities it describes, as per the general character of the data it encompasses. The DBpedia In- formation Extraction Framework transforms semi-structured data from Wikipedia into structured RDF. However this extraction framework of- fers a limited support to handle measurement in Wikipedia. In this paper, we describe the automated process that enables the creation of the Chaudron dataset. We propose an alternative extraction to the tra- ditional mapping creation from Wikipedia dump, by also using the ren- dered HTML to avoid the template transclusion issue. -

Easychair Preprint Digital Curation with Semantic Mediawiki And
EasyChair Preprint № 1853 Digital Curation with Semantic MediaWiki and Wikidata in numismatic research Bernhard Krabina EasyChair preprints are intended for rapid dissemination of research results and are integrated with the rest of EasyChair. November 5, 2019 Digital Curation with Semantic MediaWiki and Wikidata in numismatic research Bernhard Krabina1[0000-0002-6871-3037] 1 KDZ – Centre for Public Administration Research, Guglgasse 13, 1110 Vienna, Austria [email protected] Abstract. The FINA wiki is a Semantic MediaWiki (SMW) supporting numis- matic research showing how digital curation can be facilitated. It focuses on cu- ration of non-published material such as letters or manuscript sources scattered over archives and libraries across the world and previously neglected by scholars. A vast number of knowledge visualisations like maps, timelines, charts, word clouds or flow charts provide researchers with better support for handling large amount of content. With a simple mechanism, SMW can query Wikidata and users adding content can decide to use the suggested Wikidata IDs as point of reference. By leveraging Semantic Web standards, SMW instances can ensure long-term viability of valuable digital content. Keywords: Digital Curation, Semantic MediaWiki, Wikis, Wikidata, Semantic Web, Knowledge Visualisation, Collaboration, Metadata, Controlled Vocabu- laries, Numismatics. 1 Introduction 1.1 Digital curation Librarians and archivists collect valuable information, organize it, keep it in usable condition and provide access to users. Though the forms of content have changed throughout the years from handwritten items and published books now to digital con- tent, the purpose of librarianship and archiving has always been to collect and provide effective access to curated information. -
