Semantic Information System of Historical Castles over Beşparmak MountainsSemantic Information System of Historical Castles over Beşparmak Mountains


IntroductionIntroduction

• An extension of the current World Wide Web that does not only provide information at the syntactic level to human users, but also at a machine-understandable.

• In my case study, I mention that historical castles over Besparmak mountain information systems by semantic web technologies.



Introduction (Cont.)Introduction (Cont.)

• Develop Castle data with Web Ontology Language (OWL)

• Two different parts– ontology part – semantic search part



DETAIL INFORMATION ABOUT DETAIL INFORMATION ABOUT THE CASE STUDYTHE CASE STUDY

• Platform and Tools– Protégé 2.1.2

Ontology Representation

– Algernon

Inference Engine

Ontology Structure (Cont.)Ontology Structure (Cont.)• Ontology is created with OWL with RDF/XML

• Protégé is used for producing – classes – properties – relations– individuals



Ontology Structure (Cont.)Ontology Structure (Cont.)• How to create Classes with Protégé ?

<owl:Class rdf:ID="Consrtuction"/>

<owl:Class rdf:ID="Kantara"><rdfs:subClassOf><owl:Class rdf:ID="Castle"/></rdfs:subClassOf>

</owl:Class>



Ontology Structure (Cont.)Ontology Structure (Cont.)

• How to create Properties with protégé?

<owl:DatatypeProperty rdf:ID="d_lefkosa">

<rdfs:range

rdf:resource="http://www.w3.org/2001/XMLSchema#positiveInteger"/>

<rdfs:domain rdf:resource="#Distance"/>

</owl:DatatypeProperty>




• How to create Relations with protégé?

<owl:ObjectProperty rdf:ID="C_D">

<rdfs:range rdf:resource="#Distance"/>

<rdfs:domain rdf:resource="#Castle"/>

</owl:ObjectProperty>




• Individuals:

There are 3 different castles and their features inserted into Castle ontology



Search Search

• The Algernon tab of Protégé was used for the semantic search part, which is a Protégé tab plugin

• Done same search using SQL for comparing performance and strength



Search (Cont.)Search (Cont.)•Find a castle name, castle height and check if they have an east coast view which are modified in 11. century



Search (Cont.)Search (Cont.)•Find a height of Kantara



ComparisonComparison

• When I tried to do same searches I realized some implementations were not possible.

• Even some of them possible at this time the search way was very complicated.



Conclusion & Future WorkConclusion & Future Work

• When I made semantic search, I realized result are comparative, and no need to know all class names.

• This case study is limited only historical castles over Besparmak Mountains, for the future work, I can add other castle in my project.
