Overview

Semantic MediaWiki is a great tool to build social webtop.

RPI focuses on three interesting directions

• Education: Applications and Tutorials
• Best Practice: Extensions and Templates
• Theory: Formal Semantics, Concept Modeling

RPI Contributions

SMW Extensions:Core Selection

extensions

• MediaWiki
  • Help:ParserFunctions
  • Help:StringFunctions
  • Help:VariablesExtension
  • Help:CategoryTree - (optional) tree view of ontology
  • Help:LdapAuthentication - (optional) one account for multi-wiki login
• Semantic MediaWiki
  • Help:SemanticMediaWiki
  • Help:SemanticForms

installation

• Step 1: download and install MediaWiki -- we currently use mediawiki 1.13.2
• Step 2: download the above extensions -- we current uses smw-ext-core.tar.gz
• Step 3: append LocalSettings.php with extension configuration -- here is an example: LocalSettings.ext.core.php, LocalSettings.ext.ldap-slave.php

RPI Extension

PHP Extensions

• Help:SemanticQueryPlus - extend SMW to support negation, transitive properties, integrity constraints and cardinality counting etc.
• Help:AskMany - query semantic content from both local and other SMW
• Help:SimpleExport - support editing/embedding/exporting text in arbitrary format in MW, and export them with appropriate mime content-type.
• Help:SemanticHistory - encode/export revision history in RDF using PML2 vocabulary.
• Help:TetherlessMap - mashup GoogleMap with SMW query, support layering objects by semantics
• Help:DBLP Import - batch importing DBLP papers in bibtex
• Help:SMW Page Refresh -batch refresh SMW pages
• Help:ArrayExtension - defines an additional set of parser functions that operate on arrays.
• Help:RDFa Extension - provides the functionality of exchange semantic data of Mediawiki pages with other applications in the RDFa format.

Wiki Templates

• Semantic Wiki Best Practice Templates
  • Help:SBP FIT - foundation information templates for encode and render semantic annotations
  • sbp.rule - support simple rules (e.g. inverse, uncle) on SMW
• OWL Editing and Controlled Natural Language Interface
• Controlled Natural Language Interface

Theory

• semantic wiki concept modeling - formal semantics

RPI Applications

• Group Portal - managing the group
• RPI MAP - in mashup including RPI events, Google Map, user contributed knowledge
• Wine Recommendation Wiki - out mashup with wine ontology
• TAMI policy test-bed - editable semantic transaction log
• Issue Tracker - Relational Modeling
• Semantic Blog - data editing protection
• Semantic Job List -

In Progress

• upcoming works:
  • Semantic Wiki Data validator - extension of TW OWL Instance Data Validator, see also Characterizing and Detecting Integrity Issues in OWL Instance Data
• Development Details

Events

• Semantic Wiki Face to Face Meeting at AAAI Spring Sympothium. AAAI-SSS-09: Social Semantic Web: Where Web 2.0 Meets Web 3.0
