Conference Paper
This is a concept paper that introduces the Cognitive Internet of Things and particularly the role that human users play in it. The Cognitive Internet of Things, which forms a Collective AI, based on autonomous software agents, with things that can sense, think and act. We address three specific IoT challenges from a human-centred and social way: i...

This paper proposes gesture performance as one main channel for assessing collaboration skills, while multiple users solve a problem collaboratively on a tangible user interface. Collaborative problem solving incorporates two dimensions, complex problem solving and collaboration. Thus, the technology-based assessment of collaborative problem solvin...
Chapter
Human–robot interaction is a well-studied research field today; robots vary from tele-operators and avatars to robots with social characteristics. In this review paper, first we present related work on tele-operation, mobile robotic telepresence, and social robots. Then, we focus on the role of gestures and body language in robotics, and more preci...
Chapter
The construct to assess collaborative complex problem solving has two dimensions: the collaboration and the complex problem solving construct. Both have been defined in the past in the literature, but unfortunately no common model exists. In addition, current assessments lack of authentic tasks which enforce both face-two-face collaboration while s...

Localisation is the adaptation of a product to a language-culture combination, called target locale. Software and website localisation are the two most common types of localisation; many industries and particularly, language service providers (LSPs) offer such services. In this article, though, we will focus on localisation in Academia and particul...

Article
Full-text available
In this paper we examine the model of crowdsourcing for translation and compare it with Machine Translation (MT). The large volume of material to be translated, the translation of this material into many languages combined with tight deadlines lead enterprises today to follow either crowdsourcing and/or MT. Crowdsourcing translation shares many cha...

Thesis
Full-text available
Idiomatic expressions pose a particular challenge for the today';s Machine Translation systems, because their translation mostly does not result literally, but logically. The present dissertation shows, how with the help of a corpus, and morphosyntactic rules, such idiomatic expressions can be recognized and finally correctly translated. The work l...
