Pagina 2 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 Current data collection may be incomplete No unique naming assumption Multiple URI s for the same thing Much inferencing Helps handle incomplete data Ontologies Define data structure and inferencing

Fresnel Forms plugin for Protégé

Pagina 5 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

Pagina 11 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

http://en.wikipedia.org/wiki/fresnel_lens 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

Pagina 22 Default browser Wikipedia Fresnel Forms, default Property order not normalized Property display for type No tailored CSS Simple two-column table

Pagina 23 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 24 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

Editing the interface with Fresnel Forms

Pagina 26 Edited browser Wikipedia Fresnel Forms, edited 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

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 * ~500 from Fresnel Forms algorithm applied to the DBpedia ontology Pagina 29

Pagina 34 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 Plus reasoner in Protégé? Fresnel Forms generates wiki that handles rules as constraints Like the Ampersand wiki And then with BI
