Credibility

Credibility shows whether the information provided can be checked with reliable sources. Using reliable sources in Wikipedia is one of the important criteria for writing articles with high quality. Readers of the encyclopedia must be able to check where the information comes from. Therefore, one of the most commonly used measures related to credibility is the number of references in Wikipedia articles or the external link count. One of the related studies has shown that depending on the references, users can assess the trustworthiness of Wikipedia articles.

Here not only the quantity, but also the quality of the sources can be taken into account. One of the possibilities is to estimate the popularity of a reference and its domain based on the visit count or the number of incoming links from other websites. For this, data from search engines such as Google, Baidu, Yahoo, Bing, and Yandex, as well as specific tools such as Alexa, can be useful. Another possibility is to evaluate scientific references using Altmetric and other tools.

Credibility is one of the quality dimensions of Wikipedia articles.

As in the case of Wikipedia articles, credibility is related to the analysis of references. Depending on the topic and the language version, within each infobox you can find parameters with similar references. To assess credibility, such measures as the number of references, the number of unique references, and the references-to-filled-parameters ratio can be used.
