Item Defining user-generated services in a semantically-enabled mobile platform(2010) Davies, Marcin; Fensel, Anna; Carrez, François; Narganes, Maribel; Urdiales, Diego; Danado, José; SWTMobile computing enables end-users not only to access and consume information on-the-go but also to act as service and content providers. With the right tools, end-users can create small services on their mobiles and share valuable and context-aware information with others. This work introduces a platform for end-user generated mobile services - so-called microservices. As a key component we present a microservice description language for user-driven mobile service creation, powerful service discovery, and platform-independent service execution and rendering. The paper also gives insight into the visual authoring tool and the user feedback gathered in evaluations.Item M:Ciudad: An infrastructure for creation and sharing of end user generated microservices(2008) Davies, Marcin; Gil, Guillermo; Maknavicius, Linas; Narganes, Maribel; Urdiales, Diego; Zhdanova, Anna V.; Quantum; SWTWe present an infrastructure for the creation and sharing of end-user generated microservices. Main elements of the conceived semantic microservice model, the microservice lifecycle and a high-level architectural view of the m:Ciudad infrastructure are discussed.Item m:Ciudad: Enabling end-user mobile service creation(2011-11) Davies, Marcin; Carrez, François; Heinilä, Juhani; Fensel, Anna; Narganes, Maribel; Danado, José Carlos dos Santos; SWTPurpose: Mobile computing enables end-users to create small services on their mobiles and share valuable and context-aware information with others. The purpose of this paper is to introduce a platform for end-user generated mobile services - so-called microservices. Design/methodology/approach: As a key component the authors present a microservice description language for user-driven mobile service creation and platform-independent service execution and rendering. The paper also gives insight into the authors' visual authoring tool. The chosen design approach is evaluated in two phases: an intermediate evaluation with a small hands-on trial and an online survey; and a final laboratory test with 24 test users in total. Findings: The paper provides empirical insights about the methods and motivations of end-users creating small mobile services. The main purposes of service creation would be mostly to exchange information, stay in contact, and just for fun (on the basis of non-commercial use). The evaluations also indicate the visual drag and drop approach of putting service blocks together as being the most favored in terms of user satisfaction. Originality/value: The concepts and findings introduced in this paper will help in designing mobile service authoring environments, which is appealing to software communities/vendors and mobile network operators. The presented platform is, to the authors' knowledge, the first designed and implemented infrastructure enabling end-user mobile service creation.Item MOSS: Mobile social spaces(2008) Zhdanova, Anna V.; Davies, Marcin; Jorns, Oliver; Stavroulaki, Vera; Demestichas, Panagiotis; Gonzalez, Marta; Moessner, Klaus; Carrez, Francois; Rajasekaran, Hariharan; Iacono, Luigi Lo; SGWe present an emerging approach of Mobile Social Spaces (MOSS) that intends to improve the ways in which people communicate in the modern world. Pervasive content and service creation and provisioning, in particular for dynamically changing social groups, is a complex task and subject to varying locations of individuals, of the complete group and its context. MOSS tries to remove some of the obstacles in this area and defines a range of functionalities that will support dynamic ubiquitous creation and instantiation of community content and services.
