| - | To support AI teaching process and idea of a Semantic Wiki based on Prolog emerged. | ||
| - | It would support running Prolog code on the web server while rendering a wiki page. | ||
| - | Contents of such a page consists of a human-readable text, and optionally images, attachments etc, and a machine-readable and automatically interpreted knowledge expressing what the page is about. | ||
| - | |||
| - | To support Prolog programming within the wiki there is an ongoing prototype implementation of a Prolog inference engine embedded into a DokuWiki system working as its extension. | ||
| - | It is called Prolog DokuWiki. | ||
| - | |||
| - | As a result, in addition to text-based human-readable contents, there are Prolog clauses embedded into wiki pages. | ||
| - | These clauses can be automatically interpreted upon requesting the page. | ||
| - | Results of the interpretation (inference) process are directly rendered into the page. | ||
| - | |||
| - | This constitutes a Semantic Wiki System based on Prolog. | ||
| - | It is similar, to some extent, to the semantic wiki systems currently available (Semantic MediaWIki, IkeWiki, SweetWiki). | ||
| - | Other semantic wiki systems use XML to annotate gathered information semantically while Prolog DokuWiki uses Prolog language clauses. | ||
| - | Furthermore, the clauses are interpreted upon displaying a given page. | ||
| - | |||
| - | The extension introduces a new element indicated by a tag called ''prolog''. | ||
| - | Any text within the element is treated as Prolog clauses, it is interpreted by an externally launched Prolog inference engine. | ||
| - | As the inference engine SWI-Prolog is used. | ||
| - | |||
| - | Upon rendering a page with a ''prolog'' element, the wiki system launches the inference engine which process clauses within the tag. | ||
| - | Standard output of the inference process is displayed in place of the element. | ||
| - | |||
| - | There are special predicates which allow populating knowledge base with clauses from arbitrary chosen pages or namespaces. | ||
| - | There is a ''wiki/1'' predicate defined which triggers the inference engine to interpret clauses embedded within other wiki pages. | ||
| - | If the first argument is a valid wiki page, the predicate browses it and interprets (consults) all clauses within ''prolog'' tags on this page. | ||
| - | If the argument is a namespace it browses all pages from this namespace and interprets all clauses found within the pages. | ||
| - | There is another predicate ''wiki_recursive/1'' which interprets clauses from all pages in the given as a first argument namespace and all namespaces within it recursively. | ||
