Automatic hyperlinking

An autolink is a hyperlink added automatically to a hypermedia document, after it has been authored or published. Automatic hyperlinking describes the process or the software feature that produces autolinks. Segments of the hypermedia are identified through a process of pattern matching. For example, in hypertext, the software could recognise textual patterns for street addresses, phone numbers, ISBNs, or URLs.

In a distributed hypermedia system, such as the World Wide Web, autolinking can be carried out by client or server software. For example, a web server could add links to a web page as it sends it to a web browser. A browser can also add links to a page after it has received it from the server.

Examples

Wikipedia

MediaWiki and Wikipedia have the "Magic links" feature that automatically adds hyperlinks to ISBN, RFC, and PMID data.[1]

Google Toolbar

AutoLink is a feature of the Google Toolbar. Users can convert street addresses, ISBNs in a web page in their browser to links by clicking a button on Google Toolbar. The links direct the users to Google Maps for street addresses and Amazon.com for book information.[2]

Since introduced in February 2005, there has been a lot of controversy about this feature. Some webmasters expressed their concerns over the AutoLink feature claiming that Google had no rights to modify their webpages or to direct the users to a commercial website such as Amazon.

This caused Barnes & Noble, a competitor of Amazon, to link all ISBNs on their site back to themselves to prevent people clicking them to take them to their competitor.

Google sceptics compare it with Microsoft's unpopular SmartTags, which ultimately proved too controversial and were dropped.[3]

Trac Wiki Engine

Trac is a web application for issue tracking in software development. It has a wiki engine which is used for all text and documentation in the system. This includes not only wiki pages but also tickets and check-in log messages. These pieces of text have AutoLinks created, for example the text ticket:1 links to ticket 1. This is an example of server-side AutoLinking.[4][5]

AutoLinker

AutoLinker is a plugin application which has been developed for vBulletin forum software. It allows keywords set by the board administrator to be turned into hyperlinks or popups automatically any time they are used in a forum post or message.[6]

Tomboy Notes

Tomboy Notes is a personal wiki and text editor for Linux that creates automatic hyperlinks for web and email addresses while the text is being edited.[7]

Moodle

The moodle online course platform uses autolinking for automatic linking of terms within a moodle site to a glossary or database entries, or to resources within the same course.[8]

Firefox plugin linkator

Linkator takes a different stance on the concept of autolinking by automatically creating a search link from manually selected text. [9]

Wiki Hyperlinks searches for entities in a given text which are title case, then automatically adds a hyperlink to each entity from Wikipedia. It also has a feature for creating hyperlinks from manual text selections. [10]
