Problem of wikis like Wikipedia

User wants to know: “What are the 10 largest capitals located in the European Union?”

Wikipedia should be able to solve that question Contains cities, their population and information about their status and

location

Problem: The Wiki cannot understand what the text on a page means


How can Semantic MediaWiki (SMW) help?

A simple numberA simple link in MediaWiki pointing to another article



A typed link (relation) in SMW adding semantics

Similar semantic markup for an attribute value

FactBox: semantic annotations of an article

at one glimpse

Category annotation (also available in

MW)

SemanticAnnotations



Knowledge becomes machine-interpretable and can be processed by SMW

Query for the largest capitals in the European Union


Overall features of SWM+

Feature groups of SMW+ Knowledge authoring (e.g. via forms, editors, annotation toolboxes) Knowledge retrieval (e.g. via query interface, search engine) Knowledge organization (e.g. via ontology browser, gardening

framework) Knowledge interconnection (e.g. via data import from external data

sources and web services, MS Excel Client, Triple Store connector)


Knowledge Authoring

Semantic Forms conveniently add and edit structured data (being semantically annotated

in the background) easily create and customize your own semantic forms


Knowledge Authoring

Advanced Annotation Mode provides a user-friendly GUI for annotating articles semantically no need to struggle with the wiki source text user is supported via syntax highlighting and auto-completion


Knowledge Authoring

Semantic Toolbar easily inspect, create and alter the semantic annotations of a wiki article frees the user from having to know the specific wiki text mark-up means for category annotations, property annotations and property

attributes


Knowledge Authoring

WYSIWYG editor easily format text, create tables and embed images without having to

cope with the wiki source text directly embed queries (via Query Interface) and embed and tag media

files (e.g. documents, image, audio and video files)


Knowledge Retrieval

Query Interface allows to assemble complex queries easily via a GUI user is supported via intelligent auto-completion preview results via different result printers and formats


Knowledge Retrieval

Enhanced Retrieval search engine auto-completion, typo-correction (“did-you-mean”) and filtering full-text search also on uploaded PDF and DOC files advanced search

wildcard, fuzzy-search, boolean operators and path search


Knowledge Retrieval

Semantic Treeview populates hierarchical structures automatically from arbitrary wiki

elements such as categories, articles or semantic data suitable for the dynamic generation of browseable index structures or

TOC


Knowledge Organization

Ontology Browser gives an overview of the wiki's ontology and semantic facts users can navigate through the category and property hierarchy and

inspect instances and their characteristics administrators can change the ontology, e.g. by adding and renaming

categories or deleting instances



Gardening Framework allows you to improve the quality of your wiki via automatic bots check the knowledge base for inconsistencies and detect anomalies such

as undefined entities, pages without annotations or empty categories import and export functionality, e.g. for populating the knowledge base

of a wiki with an existing ontology



Access Control Access Control Lists (currently):

restrict access to different elements of your wiki for single users or entire user groups

protection of namespaces (e.g. for articles in the namespace 'special'), categories (e.g. for articles in the category 'protected') and single article pages (e.g. for the article 'internal administration')

drawbacks: only administrators can change access rights only one Access Control List which is not suitable for intense use (i.e.

thousands of individual rights)



Access Control New access control (HaloACL) planned:

HaloACL can protect individual pages, instances of categories and namespaces. (Values of semantic properties will follow).

Users can define their own groups which can contain users and other groups Every user can easily protect his own articles HaloACL supports the actions read, edit with form, wysiwyg, annotate, edit,

create, move and delete Access rights can be defined and reused in other access rights Every user can define a rights template that is automatically applied to his

newly created articles Supports a whitelist A comprehensive GUI is planned


Knowledge Interconnection

MS Excel Client query semantic data and import the results from within MS Excel e.g. easily transfer project data gathered in your wiki and reuse it for

further calculations in Excel



Data and term import framework to import structured data and vocabularies into the wiki from

any data source possible sources: CMS, databases, wikis, files, web services current modules allow import from CSV files and web services



Web Service integration call external web services from the wiki and embed the web service

results into wiki articles in principle every application (e.g. CRM, ERP and ECM systems) that

offers SOAP and RESTful web services can be integrated



Triple Store connector connect a triple store and query the knowledge base directly within the

wiki or from remote by using SPARQL queries connectors available for OntoBroker and Jena triple store advanced reasoning, e.g. supporting inverse, symmetric and transitive

properties or user-defined rules
