In this work, a framework to model the Supply Chain (SC) Collaborative Planning (CP) process is proposed. The main contributions of this framework concern 1) the presentation of the decision view, the most important one due to the characteristics of the process, jointly within the physical, organisation and information views, and 2) the simultaneous consideration of the spatial and temporal int...

This paper demonstrates the process of identity formation in the collaborative learning of programming through AlgoArena, which is educational software for learning programming. AlgoArena is a collaborative educational system through which learners can learn programming by participating together in the formation of a community of practice and their identity in it. This paper investigates how a ...

In this paper, an extension of tensor factorization based on nonlinear transformation is proposed to formulate collaborative filtering using spatiotemporal information. The nonlinear function we adopted for the transformation has only one tuning parameter, but it will give us greater flexibility to model observed data more precisely. We experimentally investigated the effectiveness of our metho...

We propose an enhanced collaborative filtering method using Hofstede’s cultural dimensions, calculated for 111 countries. We employ 4 of these dimensions, which are correlated to the costumers’ buying behavior, in order to detect users’ preferences for items. In addition, several advantages of this method demonstrated for data sparseness and cold-start users, which are important challenges in c...

Collaborative recommender system has been an important and popular approach in making recommendations. However, it suffers with the cold start and sparsity problems. Therefore, to alleviate the problems, we have combined a set similarity and user evaluation method in collaborative filtering by introducing some additional weight parameters. Further, we optimize these parameters by Particle Swarm...

Zebu is an educational groupware technology which facilitates the use of standard WWW software to support collaborative project-based learning. This paper discusses the promise of Zebu in helping teachers and students overcome some technical and practical, educational problems inherent in WWW-based technologies, allowing them to more fully realise the potentials of the WWW as a technology for c...

We introduce a method for promoting reflective conversations during collaborative work which enables participants to explore their cognitive goals and processes and thereby develop a metacognitive understanding of their practice. This method, termed "cognitive facilitation," seeks to provide a conceptual and linguistic basis for metacognitive reflection by "seeding" conversations with a cogniti...

In this paper, we describe a rule-based message passing method to support developing collaborative applications, in which multiple users share resources in distributed environments. Message communications of applications in collaborative environments tend to be very complex because of the necessity to manage context situations such as sharing events, access controlling of users, and network pla...
