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.

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

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.
