Nowadays, end users are surrounded by plenty of services that are somehow supporting their daily routines and activities. Involving end users into the process of service creation can allow end users to benefit from a cheaper, faster, and better service provisioning. Even though we can already find tools that face this challenge, they consider end users as isolate individuals. In this paper, we investigate how social networks can be used to improve the composition of services by end users. To do so, we propose a graph-based definition of a social structure, and analyse how social connections can be exploited to both facilitate end users to discover services through browsing these connections, and recommend services to end users during the composition activity. As proof of concept, we implement and evaluate the proposed social network in the context of EUCalipTool, a mobile end-user environment for composing services.

在服务组合中支持最终用户的社交网络：概念的定义和证明

如今，终端用户被大量服务所包围，这些服务以某种方式支持他们的日常生活和活动。让最终用户参与服务创建过程可以让最终用户受益于更便宜、更快和更好的服务供应。尽管我们已经可以找到面临这一挑战的工具，但他们将最终用户视为孤立的个体。在本文中，我们研究了如何使用社交网络来改善最终用户的服务组合。为此，我们提出了基于图的社交结构定义，并分析了如何利用社交联系来促进最终用户通过浏览这些联系来发现服务，并在组合活动期间向最终用户推荐服务。作为概念证明，
