What is Service Science, and why might it be important? SERVICE SCIENCE
What is SSME?(Services Sciences, Management, and Engineering) • The application of scientific, management, and engineering disciplines to tasks that one organization beneficially performs for and with another (‘services’) • Science is a way to create knowledge • Engineering is a way to apply knowledge and create new value • Business Model is a way to apply knowledge and capture value • Management improves the process of creating and capturing value

Applied Examples SERVICES REPRESENTATIONS
Variety of Services Representations • Semantic, general purpose, for the Web: WSMO, OWL-S • Business processes orientation: USDL • Mobile platforms and user presentation-oriented services: m:Ciudad example • Industrial mobile apps: Android example
WSMO – W3C Member Submission (http://www.wsmo.org) Objectives that a client may have when consulting a Web Service Provide the formally specified terminology of the information used by all other components • Semantic description of Web • Services: • Capability (functional) • Non-functional properties • Interfaces (usage) Connectors between components with mediation facilities for handling heterogeneities
OWL-S – W3C Member Submission • OWL-S represents an upper ontology for the description of Semantic Web • Services expressed in OWL. • It has its roots in the DAML Service Ontology (DAML-S). • It adopts existing Semantic Web recommendations (i.e. OWL). • It maintains bindings to the Web Services world by linking to WSDL descriptions. • The OWL-S class Service • provides an organizational point of reference for a declared Web service. • The class has three properties: • presents • Defines what service does. • Points to the ServiceProfile instance. • supports • Defines how to access the described service. • Points to the ServiceGrounding instance. • describedBy • Defines how the service works. • Points to the ServiceModel instance. OWL-S Conceptual Model Figure taken from David Martin at al. OWL-S: Semantic Markup for Web Services, W3C Member Submission 22 November 2004
USDL: Universal Service Description Language(by SAP) l Business part defined explicitly
m:Ciudad – VisionAn example of an approach for user-generated mobile services 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 servicesand their associated contents. • Fixed versus mobile service convergencein a wide sense: one worldwideuser-powered content network. • Efficient context utilization. Automatic/manualcontext-aware content generationand publication. • Discovery, access and mobile-to-mobilecommunication in a very distributed, volatileplatform (such as the mobile one, with theservice “not-always-on” paradigm). Question: What is the supposed m:Ciudad business model, and how it can be attractive for smaller mobile operators? m:Ciudad microservices http://www.mciudad-fp7.org
m:Ciudad – Mobile Service Model High Level View • Logic • Metadata • „Meta-metadata“ • Content(Parameters, Instantiation) • Presentation „Exposable“ parts are modelled semantically and are on the client side
Services Representations - Discussion Questions • How many more service representations and ontologies to come? • Could there be one that fits all? • If yes, how would it look like and how would an agreement on it be achieved?
Applied Examples From “Walled Gardens” to Wholesale Applications Community (WAC)
Mobile Services: a View from the („Walled Garden“) Mobile Operators Perspective • Walled closed gardens with resources to benefit from: • Own networks • Own standards • Political alliances, device manufacturers bindings, etc. • Own mobile platforms from manufacturers • Blown-up monopolistic pricing • Own Apps stores • Own-closed so on „You do not need to be good, you need to be better than competitors“ – a representative of an undisclosed leading national mobile operator from one of the EU countries in 2008
Mobile Services: a View from the (Open) Web Perspective, 2009 • Web has had a certain success going mobile • Many Web Services and APIs were originally developed with server to server or server to browser in mind, not mobile applications Yet it is still to meet mobile network operators and device manufacturers, who are about an easy profit, not openness or an „ideal free world“.

WAC – Mobile Web 2.0 • Wholesale Applications Community (WAC) platform first release in February 2011 • See a seprate set of WAC overview slides: http://www.slideshare.net/mobile20/wholesale-applications-community and links to the websites in the references.
From „Walled Gardens“ to WAC - Discussion Questions • Will WAC or its approach be successful? • What would successful WAC services offer and how would they look like?
Applied Examples MOBILE ADVERTISING
The problem with traditional advertising is that it's a "disconnected" process
Trends on why brand marketers have to beyond just messaging • Mobile services and web applications are the future • We are creators not consumers (the power of user generated content) • “I am not a number, I am a tag“ (no need to know a number/IP to call someone – disruptive for telecom businesses) • Communities will the way to build engagement (the population that is always in contact with friends and colleagues and trust them more than professional branded messages)
SMS as graffiti. The idea is that you send in your text message to the central system and then the messages are projected on to buildings (interior or exterior) in specific shapes or formats. The text messages appeared in speech bubbles. Art meets mobile meets social media.
Nike ID • Nike erected a large, interactive • billboard in Times Square. • Passers-by could use their cell • phones to text in their own custom • design and receive a free pair of • Nike IDs. • Individuals went nuts when they • saw their own shoes posted live on • the jumbotron in front of them. • Nike gave away 3000 pairs • of shoes in this promotion • Users were just as excited by their • design on the billboard as they • were by the free footwear
Why is it important to work together? SMEs in Location Aware Mobile Advertising www.sengaro.com www.poido.ru
By 2011, global advertising industry will be close to $600B. Can mobile start to increase its revenue share from its current levels of less than 0.2% to 2-5% by then?
Mobile Advertising - Discussion Questions • How will the advertisement of the future look like? • Who will benefit the most if it goes mobile? • Where could semantic technologies add value?
Summary • Service Science appearance is linked to the fact that we move to a service economy • There are numerous challenges in new technology and only part of them are technical => cooperation across research fields is required • also at times cooperation with such entities as policy makers, funding agencies, politicians, press, etc. makes an impact too • There is also a large potential for beneficial adoption of Semantics in real world (here, mobile) services
