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,[1] and in Wikipedia represents a summary of information about the subject of an article.
[6] On Wikipedia, an infobox is transcluded into an article by enclosing its name and attribute–value pairs within a double set of braces.
[10] As of August 2009, English Wikipedia used about 3,000 infobox templates that collectively used more than 20,000 attributes.
[15][16] 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.
[11] DBpedia uses structured content extracted from infoboxes[2] 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.
[17] Machine extraction creates a triple consisting of a subject, predicate or relation, and object.
[1] Each attribute-value pair of the infobox is used to create an RDF statement using an ontology.
