Hoda Sepehri Rad and Denilson Barbosa. 2012. Identifying controversial articles in Wikipedia: a comparative study. In Proceedings of the Eighth Annual International Symposium on Wikis and Open Collaboration (WikiSym '12). Association for Computing Machinery, New York, NY, USA, Article 7, 1–10. https://doi.org/10.1145/2462932.2462942 ABSTRACT Wikipedia articles are the result of the collaborative editing of a diverse group of anonymous volunteer editors, who are passionate and knowledgeable about specific topics. One can argue that this plurality of perspectives leads to broader coverage of the topic, thus benefitting the reader. On the other hand, differences among editors on polarizing topics can lead to controversial or questionable content, where facts and arguments are presented and discussed to support a particular point of view. Controversial articles are manually tagged by Wikipedia editors, and span many interesting and popular topics, such as religion, history, and politi...
Angles, R., Aranda, C.B., Hogan, A., Rojas, C., Vrgoč, D. (2022). WDBench: A Wikidata Graph Query Benchmark . In: , et al. The Semantic Web – ISWC 2022. ISWC 2022. Lecture Notes in Computer Science, vol 13489. Springer, Cham. https://doi.org/10.1007/978-3-031-19433-7_41 Abstract We propose WDBench: a query benchmark for knowledge graphs based on Wikidata, featuring real-world queries extracted from the public query logs of the Wikidata SPARQL endpoint. ... WDBench thus focuses on three main query features that are common to SPARQL and graph databases: (i) basic graph patterns, (ii) optional graph patterns, (iii) path patterns, and (iv) navigational graph patterns. ... Using this benchmark, we present and compare performance results for evaluating queries using Blazegraph, Jena/Fuseki, Virtuoso and Neo4j. [4 grupos de queries, CGP somente OPTIONAL] 1 Introduction With may options available, it can be difficult to choose a suitable engine to support queries ...
