In addition, if semantic markup within the wiki is stored within templates, otherwise known as semantic templates, a wiki can easily gain a solid data structure. While these are generally helpful, consider the category on Wikipedia called " 1620s births" if the information in these pages were stored using SMW, these categories could be replaced by simple semantic values, reducing the need for a complex classification system. MediaWiki wikis tend to make heavy use of categories for structuring data. The various display formats defined by additional extensions, such as Extension "Semantic Result Formats" and Maps (formerly Semantic Maps), allow for displaying of information in calendars, timelines, graphs and maps, among others, providing a much richer view of the data than simple lists and tables would. They are always up-to-date and can easily be customised to obtain further information. In SMW, lists are generated automatically. Furthermore, the number of potentially interesting lists is huge, and it is impossible to provide all of them in acceptable quality. These lists are prone to errors, since they have to be updated manually. In some cases, non-semantic wikis contain human-generated lists Wikipedia itself has thousands, like " List of metropolitan areas in Spain". Lists and tables are a natural way to view information at a glance. Here are some of the benefits of using SMW: While this at first appears to make things more complex, it can also greatly simplify the structure of the wiki, help users to find more information in less time, and improve the overall quality and consistency of the wiki. Semantic MediaWiki introduces some additional markup into the wiki-text which allows users to add "semantic annotations" to the wiki. Semantic MediaWiki enables wikis to make their knowledge computer-processable, so that you can find and display the answer to this question - and to many more. And there doesn't exist an artificial intelligence tool that could help with this task either. Categories could help to some extent, although they're not an ideal tool and maintaining them can become complex (see below). This should be an easy question to answer, but in fact it's not - you would have to read through all of the pages about projects every time you wanted to answer the question. "What are the active projects that were started in 2012?"
As a simple example, let's say you use a wiki that stores information about projects related to your organization. But though wikis are very good for storing and retrieving individual facts, they are less useful for getting queried or aggregated information.
This knowledge is mostly contained within texts and multimedia files, and is thus easily accessible for human readers. Wikis are a great tool for collecting and sharing knowledge in communities and organizations.
