Preludi:BirdWatch – lintuharrastajan semanttinenhavaintopalvelu taskussasi Tavoitteet – Luonnon biodiversiteetin hallinta havaintokannoilla – Luontohavaintojen laadun varmistus » Perustuu nykyisin laajaan vapaaehtoistyöhön – Havaitsijoiden kouluttaminen – Luontoharrastuksen edistäminen Tekniset pointit – Havainto- ja ontologisen tiedon yhdistäminen – Linked (Open) Data –teknologian pilotointi Online demo: 2

  10. 10. End-user’s Perspective 10
  11. 11. Why TravelSampo?End-user’s Perspective  Richer user experience – Richer content: » Not only for finding POIs » Additional info is created automatically based on Linked Data – Richer media: audioguiding, videos, virtual reality – Richer adaptation: Personalized, contextualized services  Support all phases of making a cultural turism trip – Plan > execute > reflect  Cross-domain content aggregation – Different kind of content from museums, libaries, etc. » E.g. events, POIs, collection items, documents, news, ...  Cross-language usage supported – Search and recommending is based on meaning » Indexing based on language-free URIs 11
  12. 12. End-user Perspective of TravelSampo Cultural Heritage Linked Data API: SPARQL, REST TravelSampo Planning Phase Executing Phase Reflecting Phase - POIs to visit -POI info supply - More info about visited POIs - Routes to go -Route guidance - Sharing experiences - Events -Recommendations Web Interface Mobile Interface Web Interface END USER ACCESSS
  13. 13. Use-case Scenario 1: Outdoors  POIs and routes connecting them – GPS coordinates – URIs for getting more info – Semantic metadata – Linked addtional data – Audioguide recordings – Accessibility information 13
  14. 14. Use-case Scenario 2: Indoors  Inside a POI: exhibition – Provide audioguide and information to mobile phones – Exhibits with ID tags for more info download » Aggeragated data about the objects » Semantic recommendations for related content 14
  15. 15. Content Provider’s Perspective 15
  16. 16. Why TraverSampo?Content Provider’s Perspective  Providing more and better content and experiences – Fulfilling underlying mission of museums  Attracting more visitors to museums and CH sites – Better online and guiding services -> more visitors – Outdoor POIs guide people into museums » Visiting a statue -> ”More similar works in museum X” – More visibility on the WWW through search engines  Aggregating & enriching & reusing content collaboratively – Content from different organizations and data sources is interlinked and enrich each other ”for free” 16
  17. 17.  Provide a simple way to create (audio)guiding online – Web-based interface for content upload » Semantic annotations for LD » Uploading images, audiofiles etc. » Geotagging POIs – Tool for creating tags for objects in exhibitions or outdoors – Real-time content publishing online and in reality: 1. Create and annotate content objects 2. Create the tag 3. Attach the tag to the object 17
  18. 18.  Saving money for museums and visitors – Self-made autoguiding is cost-efficient » Easy/cheap to create content » No special audioguide equipment is needed – Using the system is free for clients » WLAN or flat rate mobile connection Avoiding vendor lock, but supporting companies – All sofware is free and open source – Content available from open data sources – Supporting commercial services, too 18
