While the analysis of online social networks is a prominent research topic, offline real-world networks are still not covered extensively. However, their analysis can provide important insights into human behavior. In this paper, we analyze influence factors for link prediction in human contact networks. Specifically, we consider the prediction of new links, and extend it to the analysis of recurring...
Spatio-Temporal Interest Point (STIP) has been widely used for human action recognition. However, the performance of the STIP based methods are still limited in realistic datasets which often include large variations in illuminations, viewpoints and camera motions. One reason of the low performance is that the STIPs only reflect the local change in videos, which is not enough to obtain stable informative...
Over the last decades it has been observed that many companies around the world have started to adopt Distributed Software Development (DSD) to create competitive advantages. Aiming to increase such advantages, many of these companies add some team motivation techniques to DSD. However, the motivation of DSD teams reveals some peculiarities that should be taken into account. This paper presents a...
Most human centric business activities, like the handling of an insurance claim or the design of an IT solution, do not follow a formal process model word-by-word. While there are often underlying processes in place, the real business operation typically encompasses a wider scope of actions. It includes unstructured segments of human activities, additional documents and interactions, the integration...
In this paper, I outline the scope and methodology of cultural studies and the possible applications in HRI. It is not just robots that interact with humans, but humans who interact with humans through the medium of robots. Culture is the context that informs all our actions. Cultural theory's eclectic methodology is useful for sifting through a large, multidisciplinary and cross-cultural field like...
Trust is a very significant commodity in distributed networks the same as in social network. The dynamic and ephemeral nature of distributed networks environments is especially important to compute the peer trustworthy. So, the decision whether or not to trust a peer can depend on many contextual factors. We outline a context-sensitive computation approach for considering the impact of context information...
This paper proposes a novel approach for word similarity computation based on word sense vectors. The word sense vector is built using HIT-IR Tongyici Cilin (extended) for concept generalization and is further modified by the use of relative and absolute frequency filters. Experiments show that the approach not only overcomes the problem of similarity computation of unseen words but also yields a...
IT ecosystems are ultralargescale software systems that consist of various, constantly interacting and partly autonomous subsystems as well as the users of the overall system. Because of their strong integration with everyday life, these systems are often not even perceived as IT systems by its users. This is a problem for requirements engineering, as users might not know of or may not be interested...
Translation Memory (TM) consists of a collection of previously translated units of text that may prove useful in the translation of new text. The main problem faced by translators who wish to take advantage of TM is that, although search tools do exist, there is no standardized way of effectively ranking search results. This paper proposes a method for effectively ranking TM search results together...
Requirements analysis is a fundamental phase in the development of digital tools and concentrates essentially on computational aspects consisting on the identification of input and output flows as well as processing. Nevertheless, requirements analysis is difficult to conduct when contents and relations are complex and dynamic. Recently, the ecosystem approach has been used to understand and model...
Although the relations between affects and posture were the focus of several studies in Psychology, their consideration in multimodal corpora research remains scarce. In this paper we survey related studies and propose a framework for studying affective postures by integrating knowledge coming from multiple sources such as literature, video corpora, motion capture data, artistic design, and perception...
Humane care asks for designing with care and designing with users and other stakeholders at heart. The focus of the workshop is on human values in relation to pervasive technology and the outcome will be a research agenda for the nearby future.
Dementia affects large number of elderly, manifested with memory impairment symptoms at the onset. This results in difficulties for elderly in scheduling and completing daily activities. In this respect a context-aware reminder system becomes an essential tool in helping elderly navigate their daily activities. Current work on reminder systems typically follows a set of pre-defined activities, organised...

The work presented in this paper demonstrates that creative design is not a process, but rather it should be represented in terms of the dynamics of clusters of creative design activities that represent the interplay between the behaviour of creative design and its context. The clusters of creative design activities are associated with a focus aimed at achieving a certain task. It is shown that there...
This paper builds on the authors' work on security challenges in the more general pervasive domain and considers what demands the adaptive paradigm will make of the information assurance community, and conversely, what information-assurance concerns should inform the realisation of pervasive adaptation. We propose a set of concepts which would enable these concerns to be addressed should they be adopted...
