Английская Википедия:Infobox
Шаблон:Short description Шаблон:Self-reference
An infobox is a digital or physical table used to collect and present a subset of information about its subject, such as a document. It is a structured document containing a set of attribute–value pairs,Шаблон:Sfn and in Wikipedia represents a summary of information about the subject of an article.Шаблон:Sfn In this way, they are comparable to data tables in some aspects. When presented within the larger document it summarizes, an infobox is often presented in a sidebar format.
An infobox may be implemented in another document by transcluding it into that document and specifying some or all of the attribute–value pairs associated with that infobox, known as parameterization.
Wikipedia
An infobox may be used to summarize the information of an article on Wikipedia.Шаблон:Sfn They are used on similar articles to ensure consistency of presentation by using a common format.Шаблон:SfnШаблон:Sfn Originally, infoboxes (and templates in general) were used for page layout purposes.Шаблон:Sfn An infobox may be transcluded into an article by specifying the value for some or all of its parameters.Шаблон:Sfn The parameter name used must be the same as that specified in the infobox template, but any value may be associated to it.Шаблон:Sfn The name is delimited from the value by an equals sign.Шаблон:Sfn The parameter name may be regarded as an attribute of the article's subject.Шаблон:Sfn

| The infobox Infobox prepared food used on Wikipedia food-related articles, with no values specified for its parameters (attributes). | The same infobox as implemented in the article crostata. Values are to the right of the equals sign (=), and that the parameter names are the same as those in the specification for the infobox template. The values are in wiki markup: entries enclosed in square brackets (e.g. [[Tart]]) will be rendered as a link to the respective Wikipedia article (e.g. Tart), and the linked file will be transcluded into the article in place of its markup. |
On Wikipedia, an infobox is transcluded into an article by enclosing its name and attribute–value pairs within a double set of braces. The MediaWiki software on which Wikipedia operates then parses the document, for which the infobox and other templates are processed by a template processor. This is a template engine which produces a web document and a style sheet used for presentation of the document. This enables the design of the infobox to be separated from the content it manipulates;Шаблон:Sfn that is, the design of the template may be updated without affecting the information within it, and the new design will automatically propagate to all articles that transclude the infobox.Шаблон:Sfn Usually, infoboxes are formatted to appear in the top-right corner of a Wikipedia article in the desktop view,Шаблон:Sfn or at the top in the mobile view.
Placement of an infobox within the wikitext of an article is important for accessibility.Шаблон:Sfn A best practice is to place them following disambiguation templates (those that direct readers to articles about topics with similar names) and maintenance templates (such as that marking an article as unreferenced), but before all other content.Шаблон:Sfn[1]
Baeza-Yates and King say that some editors find templates such as infoboxes complicated,Шаблон:Sfn as the template may hide text about a property or resource that the editor wishes to change; this is exacerbated by chained templates, that is templates transcluded within other templates.Шаблон:Sfn
As of August 2009, English Wikipedia used about 3000 infobox templates that collectively used more than 20 000 attributes.Шаблон:Sfn Since then, many have been merged, to reduce redundancy. As of June 2013, there were at least 1 345 446 transclusions of the parent Infobox template,[2] used by some, but not all, infoboxes, on 4 251 127 articles.
The name of an Infobox is typically "Infobox [genre]"; however, widely used infoboxes may be assigned shorter names, such as "taxobox" for taxonomy.Шаблон:Sfn
Machine learning
About 44.2% of Wikipedia articles contained an infobox in 2008,Шаблон:Sfn and about 33% in 2010.Шаблон:Sfn Automated semantic knowledge extraction using machine learning algorithms is used to "extract machine-processable information at a relatively low complexity cost".Шаблон:Sfn However, the low coverage makes it more difficult, though this can be partially overcome by complementing article data with that in categories in which the article is included.Шаблон:Sfn The French Wikipedia initiated the project Infobox Version 2 in May 2011.Шаблон:Sfn[3]
Knowledge obtained by machine learning can be used to improve an article, such as by using automated software suggestions to editors for adding infobox data.Шаблон:Sfn The iPopulator project created a system to add a value to an article's infobox parameter via an automated parsing of the text of that article.Шаблон:Sfn
DBpedia uses structured content extracted from infoboxesШаблон:Sfn by machine learning algorithms to create a resource of linked data in the Semantic Web; it has been described by Tim Berners-Lee as "one of the more famous" components of the linked data project.Шаблон:Sfn
Machine extraction creates a triple consisting of a subject, predicate or relation, and object.Шаблон:Sfn Each attribute-value pair of the infobox is used to create an RDF statement using an ontology.Шаблон:Sfn This is facilated by the narrower gap between Wikipedia and an ontology than exists between unstructured or free text and an ontology.Шаблон:Sfn
The semantic relationship between the subject and object is established by the predicate.Шаблон:Sfn In the example infobox, the triple ("crostata", type, "tart") indicates that a crostata is a type of tart. The article's topic is used as the subject, the parameter name is used as the predicate, and the parameter's value as the object.Шаблон:SfnШаблон:Sfn Each type of infobox is mapped to an ontology class, and each property (parameter) within an infobox is mapped to an ontology property.Шаблон:Sfn These mappings are used when parsing a Wikipedia article to extract data.
Metadata
By presenting the basic facts of an article within an infobox, also allows the facts to be presented in a machine-friendly way allowing extra functionality such as when a link to a wikipedia is pasted into a compatible program, instead of just the link itself being posted other information such as the articles image is posted too.
