Abstract:	The use of Wikipedia as an information source is becom- ing increasingly popular. Several studies have shown that its information quality is high. Normally, when considering information trust, the source of information is an impor- tant factor. However, because of the open-source nature of Wikipedia articles, their sources remain mostly unknown. This means that other features need to be used to assess the trustworthiness of the articles. We describe article features - such as images and references - which lay Wikipedia read- ers use to estimate trustworthiness. The quality and the topics of the articles are manipulated in an experiment to reproduce the varying quality on Wikipedia and the famil- iarity of the readers with the topics. We show that the three most important features are textual features, references and images.
