Semantic Technologies for Mobile Communications: User-generated Policies and Services

1. Semantic Technologies for Mobile Communications: User-generated Policies and Services Dr. Anna V. Zhdanova zhdanova@ftw.at ftw. Telecommunications Research Center Vienna, Vienna, Austria

2. Outline • Introduction • Why: Support of Convergent Heterogeneous Environments and End-User Empowerment • How: Enabling User-Driven Semantics • User-Generated Policies • User-Generated Mobile Microservices • What: Motivating Scenarios • Conclusions

3. Evolution in Mobile Service Infrastructures – Telco View IMS 3G Wireless IP • 3G wireless + IP ++ • Standard Services Platform • Converged Applications & Content • Access Independence Wireless PSTN • Internet • VoIP • Instant Messaging • Web Applications • W-CDMA • GPRS/UMTS • Circuit switched • Analog • Digital • SS7 • ISDN • Circuit switched • Analog • Digital • 2G (GSM & CDMAANSI-41) Source: Telcordia Technologies

4. Waves of Applications Multimedia • Mobile Multimedia: • Instant Interactive multimedia • Video Messaging/Streaming • Enriched Personalized Services • Personalized Services: • Instant Messaging/MMS • Infotainment • Location Based Services • m Commerce Infrastructure Focus Applications Focus Mobile Data Service Maturity • Enhanced Mobile Browsing: • Internet • Intranet/Extranet • UMTS is Perceived • as a continuum from • 2.5G • Richer Content • Better User Experience • UMTS is Perceived • as a continuum from • 2.5G • Richer Content • Better User Experience Simple Text Messaging (SMS) Internet Browsing (WAP) GSM UMTS GPRS Source: Nortel networks

5. Mobile Location Based Services (LBS)

6. End-User Empowerment in Converging Service Platforms (1) • Redefining the role of Telco: from access to service provider • Enabling new business models (e.g. «prosumers» vs. consumers) • Inter-domain aspects: service provisioning, inter-working • Make services intelligent and easier to use (assist users) Integration with the (Semantic) Web is inevitable for having a common large information pool Semantically enabled smart user interfaces

7. End-User Empowerment in Converging Service Platforms (2) • Hiding complexity and heterogeneity • Taking benefit of existing variety of services, networks and devices • Opening platform capabilities to 3rd parties • Support multi-vendor, multi-technology middleware platforms • Provide services timely: accelerate creation & delivery of services • Fast service creation • Reduce time-to-market for new services Ontology technology is built to handle heterogeneity and variety Creation, discovery, composition of enablers and services is accelerated on the basis of shared ontologies & semantic techniques

8. Motivation for User-Generated Semantic Policies End User Perspective • Personal data and identity managment • „Who is watching me?“, e.g., choose to whom you want to reveal your location and presence and to whom not • Policy acceptance/rejection • „What is going on?“, „Why?“, e.g., learn about government, finance, legal, business procedures Organizational Perspective • Policy management • „Define, set, communicate, share policies“, e.g., conditions of selling a service at a marketplace B2B, B2C, C2B, C2C, P2P Now policies are most often texts that nobody reads.

9. A Tool for Acquisition of Semantic Policies from End-Users • Maria a :Customer. • Eshop a :Eshop. • External_Information_about_Maria • a :External_Customer_Information. • Marias_Account_at_Eshop a :Eshop_Customer_Account. • { • Maria :has Marias_Account_at_Eshop. • Eshop :receives External_Information_about_Maria • } • {External_Information_about_Maria • :is_added_to Marias_Account_at_Eshop}

10. Policy Editing – User Evaluation • 2 domain case studies • 10 test subjects • more than 200 rule modeling solutions • a human observer at tests • questionnaires after tests

11. User Generated Microservices - A Vision • m:Ciudad,a step forward in Mobile User-generated Content and Services. A service infrastructure for the mobile platform for: • Instantaneous, on-the-go service creation and provision. The mobile user as a prosumer:producer, provider and consumer of services and their associated contents. • Fixed-mobile service convergencein a wide sense: one worldwide user-powered content network. • Efficient context utilization. Automatic / manual context-aware content generation and publication. • Discovery, access and mobile-to-mobile communication in a very distributed, volatile platform (such as the mobile one, with the service “not-always-on” paradigm). m:Ciudad micro-services FP7 Obj. 1.2 STREP, 2007-2010; http://www.mciudad-fp7.org

12. „What is a microservice?“ • Logic • Metadata • „Meta-metadata“ • Content(Parameters, Instantiation) • Presentation „Exposed“ parts are modeled semantically

14. Policies: Dilbert Example

15. Microservices Scenario: Traffic Jam Killer Motivation: Share knowledge about the fluidity of the traffic and presence of mobile radars with friends.

16. Microservices Scenario: Friends Locator Motivation: Locate friends, position them and show on a map.

17. Conclusions Starbucks comes from America (and now there are several ones in Vienna!). Many would agree that coffee is better in Austria than in the US. Why wait till somebody else empowers end-users with semantic location-based mobile services in the converging world?! Thank you for your attention.
