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: 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.
