Semantic Web in a nutshell
•
A unifiable world-wide database on the World Wide Web
–
Graph of node-edge triples is like one sparse table
•
URI’s as universal identifiers
•
Open World Assumption
–
•
No unique naming assumption
–
•
Multiple URI’s for the same thing
Much inferencing
–
•
Current data collection may be incomplete
Helps handle incomplete data
Ontologies
–
Define data structure and inferencing

Fresnel Forms plugin for Protégé
Fresnel Forms plugin for Protégé
•
Protégé: Top tool for editing a Semantic Web ontology
•
Fresnel Forms plugin lets user design an interface
•
–
Generates default system interface for ontology
–
GUI-editor for interface specification
–
Fresnel is standard for semantic browser interface specification
–
Interface export to semantic wiki
–
Interface is browsing and form-based annotation
Educational context
–
Developed by two ABI projects, some functionality from a third
–
Principles from MDD and Business Rules
–
Protégé used in Semantic Web and MSC Rule based Design
–
Potential use by Masters Thesis students

Great contribution, but can’t it be easier?
•
•
•
Model-driven development
–
Start with ontology
–
Automatically generate default interface from it
–
Efficiently tailor that interface
Form-based annotation
–
Instead of text editing template parameter code
–
Guides user to enter field values that fit ontology
Direct export to Semantic Web

Fresnel: RDF interface in RDF
•
Specifies how RDF is display
•
Separates style from content: like CSS for XML
•
Also in RDF
•
Supported by multiple semantic browsers such as Longwell
http://www.w3.org/2005/04/fresnel-info/manual/
http://dig.csail.mit.edu/2006/Talks/0724-fresnel/#%2814%29
Domain-independent default for browser (Longwell)
With (handmade) Fresnel style
Wikipedia
Fresnel Forms, default
Default browser
•
Property order not normalized
•
Property display for type
•
No tailored CSS
•
Simple two-column table
Pagina 22
Default Form
•
Order same as browser
•
Shows all properties
–
Browser only those with values
•
Input fields special for data types
•
Cardinality min/max =1
•
–
Optional or mandatory
–
List or single
Autocompletion to class members
Pagina 23
Falco Paul’s BPMIT Master’s thesis
•
What is best default property order?
•
Compares algorithms for sorting ontology properties in browsers
•
Wikipedia infoboxes are truth set
•
Simple heuristic outperforms various text-processing algorithms
•
An ABI student’s research context assignment will apply this to
Fresnel Forms
•
Resulting Fresnel Forms makes a better default interface
•
Especially for Wikipedia, albeit with chicken-egg paradox
Pagina 24
Editing the interface with Fresnel Forms
Wikipedia
Fresnel Forms, edited
Edited browser
•
Property order easy to change
•
CSS
–
Fits in Fresnel standard
–
<div>-based better than table
•
“Awards” is more page link than data
annotation
•
Maybe with SPARQL queries
•
–
Age calculation
–
Honorific acronyms
Ordering of multiple values works
–
But via the wiki code
–
Not via Semantic Web

Pagina 28
That’s fine for one infobox, but what
about all the others*?
•
•
Fresnel Forms scales to process the entire DBpedia ontology
–
Default GUI display appears in a few minutes
–
Fresnel generation takes about a half hour
–
Protégé on special server makes wiki in about an hour
The new, improved Wikipedia interface is right here on my laptop
–
Jimmy Wales just needs to import the wiki XML
–
And install a few Semantic MediaWiki extensions
–
Existing infoboxes share same foundational syntax
•
Wikibots can automate some simple cleanup
•
And/or modified existing infobox templates can map to new ones
–
DBpedia ontology needs to be up-to-date
–
Default interface could use some tailoring

Fresnel Forms summary
•
Efficient building of data system interface for given ontology
•
Wikipedia infoboxes can be rebuilt with this approach and tool
•
Valorization: the OU made Wikipedia resilient
•
… and now some research context …
Pagina 33
Future work: the same, but with rules
•
Apply the course Rule based Design
–
Relation algebra logic
–
Ampersand tool
•
Relation algebra constraints plus Semantic Web inferencing
•
Masters thesis students already busy with Ampersand to
Semantic web case study conversions
•
Potential software
–
Automatic conversion Ampersand to Semantic Web plus Fresnel
–
New Protégé plugin adds relation algebra rules to ontology
•
–
Fresnel Forms generates wiki that handles rules as constraints
•
•
Plus reasoner in Protégé?
Like the Ampersand wiki
And then with BI
