The objective of the Personalized Web Tasking (PWT) workshop series is to develop a community interested in the overlap between web services (as interoperable and easily composable components) and configurable personalizable applications. On the one hand, the core web-service community focuses primarily on enabling/supporting the processes around building distributed systems using services as the...
The development of context-aware applications has been the subject of many research works in ubiquitous computing. As the modern human is getting more and more mobile, carrying an ever increasing amount of computational power around and having access to online services, the need for personalized and adaptive information services is rapidly increasing. Thus, the field of context-aware services has...
In this paper, we present a fully operational, scalable and open architecture allowing end-to-end document analysis benchmarking without needing to develop the whole pipeline. By decomposing the analysis process into coarse-grained tasks, and by building upon community provided state-of-the art algorithms, our architecture allows any combination of elementary document analysis algorithms, regardless...
Social media enhanced learning systems bring new challenges to evaluate learning environments. Many features are common with any websites and can be evaluated with common criteria. But with social media users can also contribute content, change opinions and create communities for different needs, which bring new dimensions to a quality evaluation. This research focused on finding out which are the...
The global scale and distribution of companies have changed the economy and dynamics of businesses. Web-based collaborations and cross-organizational processes typically require dynamic and context-based interactions between people and services. However, finding the right partner to work on joint tasks or to solve emerging problems in such scenarios is challenging due to scale (number of involved...
Much work is underway within the broad next generation technologies community on issues associated with the development of services to foster collaboration via the integration of distributed and heterogeneous data systems and technologies. Various technology-driven paradigms have emerged, including Web Services, Web 2.0, Pervasive, Grids and Cloud Computing. Recently, some new paradigms have emerged,...
Our work focuses on selecting a trusted service from service consumer's perspective. First, we distinguish the two kinds of trust context to separate the ability of service as both a service provider and a service consumer in a service web; and we classify the reputation into two different categories. Second we generate a reputation metric model by improving Subject Logic. The trust decision model...
Service-oriented architectures (SOA) are becoming the dominant computing paradigm, where all resources are abstracted as services to form services society. Open-access and easy-visiting of services are keys to services eco-system, thus service search engines will play an increasingly important role. Generally retrieved services are listed and ranked by the content similarities to queries. One problem...
There is an increasing number of community-based question and answer (cQA) service on the Web. Many tasks in cQA services involve in determining similarity between questions. However, finding similar questions is not trivial. In this paper we propose a new method based on a query expansion technique to tackle the similar question matching problem. We employ the information provided by the corresponding...
With the increasing demand for dynamic web service composition, traditional web service registries are no longer adequate in providing precise service selection. To address this problem, the paper proposes a fine-grain structural concept for traditional service registries, called web service community. Efficient semantic-level service enquiry and community management depend on context information...
With the emergence of Web 2.0 and the related technologies, composing services has left the traditional frontiers of enterprises. In fact, end-users need to use a certain kind of composition in different situations since Web 2.0 has brought a set of technologies making it easy to create or collaborate on new services or use others' services, e.g., mashups. On the other hand, users participate in different...
Social media services have recently become well known especially among young people [1]. In social networking sites a user can participate intensively in activities in the service. To support collaborative study at Tampere University of Technology (TUT) and also to provide social networking tools for students especially at the beginning their studies, the development TUT's own social network site...
Trust is generally based on the level and quality of interaction with the entity being trusted. In a web service or the Internet, trust is based on the level of successful and unsuccessful interactions. Successful interactions are used to model trust within the context of chains of trust in which an agent is permitted to recommend a service. This is termed trust chain since the agent need to first...
In the near future, the trend of user-generated content and services currently observable in the Internet domain will also affect the mobile environment: mobile users will become able to easily create content and small services while on the move and offer them to social communities. Mobile users will no longer be pure consumers, they will also become producers and providers of mobile content and services...
Television has always been a popular entertainment medium with considerable impact on consumer purchase behaviors. However, unlike mobiles and PCs, it has yet to support an explicit search capability that extends beyond simple content navigation. A core reason for this is lack of usable input interfaces for TV coupled with the difficulty of creating and executing queries based on rich media context...
Current trends suggest that the Pervasive systems should be adaptive and flexible. Many Message-Oriented Pervasive systems have been proposed to support on-line self-composition of services in reaction to changing contexts. However, most existing service composition mechanisms either do not consider user preferences or use proprietary typing systems. In this paper, we propose an extensible ontology-based...
In this paper we examine the problem of rich information environments and the need to narrow the agents attention to what is important for them to interact and later to evaluate and transfer reputation values, using attention allocation technique (AA). We also argue that this cannot be done without the aid of service oriented architecture (SOA). Reputation is used in our work as a service, presenting...
Pervasive or ubiquitous computing enlarged traditional computing setting into the human layer of the earth. World Wide Web is the biggest digital information layer, hence it is unavoidable to stretch and integrate such an information layer over this new enlarged computing setting. It is reasonable to call such enlarged Web environment as uWeb, UbiquitousWeb. In this paper we propose an approach and...
This paper focuses on Did@cTIC, a CoP of university teachers, and addresses the issue of capitalizing their teaching experience as well as that of reifying their practices in the form of structured documents. This paper first presents the theoretical framework describing the reification process along with the instrumental approach for tool development. Then, the contextual background and the reification...
Web 2.0 applications have become popular as drivers of new types of Web content, but they have also introduced a new level of interface design in Web development; they are focusing on richer interfaces, user-generated content, and better interworking of Web-based applications. Recognition and utilization the Web 2.0 characteristics requires a reference model to evaluate adaptation of Web based systems...
