Completeness

Completeness shows how comprehensive the description of a topic is in a document. Wikipedia articles of high quality must neglect no major facts or details and place the subject in context. One of the most popular measures for this dimension is content volume measured by article length. Length can be measured in different ways: bytes, characters, words, and others.

Completeness is one of the quality dimensions of Wikipedia articles.

Completeness of the infobox can be measured as the ratio of the number of parameter values to the number of all defined parameters in the infobox of a given type. Other measures related to this quality dimension can also consider weights for each filled parameter, where the weight is based on the frequency of filling this parameter. Here we can also take into account the length of the infobox, the number of templates, and other elements that the infobox contains.

In some topics, infoboxes can contain similar parameters, which can be omitted when calculating completeness. For example, to describe cities of Poland in some language versions of Wikipedia there is a special infobox, so the parameter about country is absent. At the same time other languages to describe the same city can use common infobox for different cities in the world, so parameter about country is important there.
