This paper is an invitation to carry out science and engineering for a class of socio-technical systems where individuals — who may be human or artificial entities — engage in purposeful collective interactions within a shared web-mediated social space. We put forward a characterization of these systems and introduce some conceptual distinctions that may help to plot the work ahead. In particul...

Although known item searching for music can be dealt with by searching metadata using existing text search techniques, human subjectivity and variability within the music itself make it very difficult to search for unknown items. This paper examines these problems within the context of text retrieval and music information retrieval. The focus is on ascertaining a relationship between music rele...

The Internet is rapidly transforming a range of human activities; socio-cognitive theory assumes that engagement in transformed activities, over time, transforms human cognition. Four hundred and six college students completed four modified cognitive assessment system subtests, each assessing one dimension of the PASS model of cognitive processing (i.e., planning, attention, simultaneous and su...

Online knowledge building communities (OKBC) reunite participants engaged in collaborative discourse. OKBCs can be made „smart“ by adding tools that predict how likely an OKBC is to integrate newcomers in existing dialogues and socio-cognitive structures. Starting from Bakhtin’s dialogical approach and polyphony theory, and building on the concept of interanimation of voices, this study explore...

Purpose — Science is subject to a normative structure that includes how the contributions and interactions between scientists are rewarded. Authorship and citations have been the key elements within the reward system of science, whereas acknowledgements, despite being a well-established element in scholarly communication, have not received the same attention. This paper aims to put forward the ...

The aim of this paper is to provide a theory of the role trust plays in knowledge sharing processes, by exploiting a cognitive model of the goals and beliefs of an agent involved in the decision of passing and/or accepting knowledge, and a related model of the symmetrical or asymmetrical trust relationships within a group (Trust-Nets). This theory is based on the claim that trust is a fundament...

Due to the proliferation of location-based information services, there is abundant urban information which makes us difficult to catch up with the characteristics and dynamics of our living space. However, nowadays, crowd lifelogs shared over social network sites are attracting a great deal of attention as a novel source to search for local information from the massive voices and lifelogs of cr...

The Dynamic Trust-based Resources (DyTR) system applies a dynamic notion of trust to ad hoc network resources. DyTR continuously assesses the trustworthiness of entities over time based on system events and controls network resources according to current levels of trust. For dynamic trust assessment, DyTR utilizes a socio-cognitive model of trust, a formal model of the essential concepts and ch...
