Goal models help elicit, specify, analyze, and validate requirements as they capture hierarchical representations of system requirements, possible solutions, stakeholder objectives, and their relationships. In the early requirements phase, goal models aid requirements engineers in understanding the goals of stakeholders and exploring solution alternatives based on their impact on these goals. Despite...
The design of recommendation method is the core of personalized recommendation, and the implementation of recommendation depends on the matching relation between user preference and resource object. This paper proposes a hybrid personalized recommendation method based on context-based collaborative filtering and knowledge recommendation, which is based on personalized recommendation knowledge model,...
The demand of product design knowledge is complex and changeable, in order to solve the problem of how to efficiently obtain design knowledge demand, based on the analysis of context aware reasoning layer characteristics, constructs a context aware service system to obtain design knowledge needs. Bayesian method is used to design the knowledge category preference situation, and according to the characteristics...
Student motivation can be enhanced by positive social interactions, which can be found in CoPs (Communities of Practice), they're based on the idea of interacting to improve a shared practice. The community offers the ability to move beyond simple information exchange to meaningful knowledge exchange through a set of responsibilities and tasks. This paper presents a description of a CoP of higher...
In this paper, we present an event handling framework for managing smart-grids and renewable energy installations: SmartSpace. Our framework aims at supporting decisions of human stakeholders, by providing adequate information to them. Different datasources feed into our framework and a variety of analysis and decision steps are supported. We are discussing potential data sources for decisions around...
Social networks have become a new form of communication that allow students to share and collaborate. In this sense, they have joined forces with self-regulated learning (SRL) skills. This paper presents an experience at the University of Santiago de Compostela to analyze how SRL is developed in a course using a social network. This research used the following: 1) MSLQ questionnaire by Pintrich and...
Urban search and rescue (USAR) missions can benefit a great deal from teams of mobile robots endowed with advanced perception capabilities. To effectively collaborate with humans, these robots should have situation awareness about their robotic and human teammates, for intuitive decision making. Moreover, robots should be able to contextually share information so that humans can benefit from augmented...
In this paper, an argumentation based method for collaborative decision making is introduced. Each group member can submit arguments to support or attack the potential solutions (or alternatives). Extra information, expressed as constraints and preferences, regarding the members' requirements is added in order to ensure the obtaining of more satisfying decisions. The IBIS model is used to capture...
We are combining symbolic and geometric planning to synthesize human-aware plans in order to deal with the complex and highly intricate planning problems induced by Human-Robot collaborative object manipulation. In this paper, we summarize our previous contributions - refining symbolic actions at geometric level, during the symbolic planning, in order to assess their feasibility and computing the...
Requirement engineering (RE) presents several challenges stemming from the required collaboration and knowledge transfer between analysists, developers and customers. In order to overcome these challenges and improve the effectiveness of RE, we developed REVISE: Requirement Elicitation and Verification Integrated in Social Environment. This tool is designed based on cognitive theories and implementing...
The need to effectively manage IT resources such that they enhance the business value of firms makes IT governance (ITG) an important issue for both IS researchers and practitioners. The purpose of this paper is to build a conceptual framework for ITG in small and medium-sized enterprises (SMEs). We first analyze the main theories applied in ITG research, and confront them with the specificities of...
Visual analytics (VA) combines the strengths of humans and computers such that joint cognitive systems are formed. To be effective, a VA tool should be designed such that the component parts of the whole system are strongly coupled and function in a harmonious fashion. These components include cognitive and perceptual issues, tasks, algorithms, data models, and other aspects of the systems that contribute...
Critical thinking is one of the key competencies listed by OECD (Organisation for Economic Co-operation and Development) [1], a central European Community organization, and is also mentioned as a learning outcome for higher education by international organizations, such as ABET, ACM, and IEEE, as well as in numerous national and university legislations regarding higher education degrees. The ability...
Military intelligence analysis (IA) support tools are often developed using generalized models of IA that fail to take into consideration the real-world constraints put on analysts by factors such as organizational structures and cultures. IA in domains where distributed collaboration is required because direct communication and coordination is infeasible represents a challenge for generalized models...
Over the past decades, intelligent conversational agents have been repeatedly used as pedagogical tools for fostering students' motivation and engagement in individual learning settings. However, in recent years, the uses of conversational agents have also been explored in collaborative contexts under the scope of Academically Productive Talk (APT). The theory of APT, which has derived from the work...
We present work towards using ontological information to facilitate collaborative tasks during operation, maintenance and service of industrial automation facilities. We use semantic models as an additional layer for a collaboration framework to enable automatic reasoning, decision support and knowledge sharing among multiple parties. Documents such as texts, workflows, images, social media profiles...
The Notification-Oriented Paradigm (NOP)defines a new approach for conception, structuring, and execution of software leading to performance improvements, organization of causal knowledge, and decoupling of programming entities when compared to standard solutions based upon current paradigms, such as the Imperative Paradigm (IP) and the Declarative Paradigm (DP). These paradigms present drawbacks...
Any activity in a computer-supported cooperative working environment produces a set of traces. In a collaborative working context, such traces may be very voluminous and heterogeneous. They reflect all the interactive actions among the actors themselves and between the actors and the system. This paper examines what is required to exploit traces in the context of a collaborative working environment...
If an individual on the edge of a problem's context can generate creative solutions to that problem, does this capacity emerge in spite of their marginality... or because of it? How can this marginality be leveraged in a collaborative context? The purpose of this paper is to explore the link between marginality and creativity through untangling of technical and social marginality. We advance the sociocognitive...
Group interaction is a key component of group-based learning. However, its implementation in existing learning practices is inefficient. Previous studies discussed the use of concept mapping in group learning. Apart from its clear benefits for group learning and interaction, deficiencies of using concept mapping in distance groups were also recognized, mainly related to labor division, group coordination,...
