In the context of PTV, an applied recommender system operating in the TV listings domain, we are examining the potential benefits in merging case-based and collaborative filtering (CF) recommendation techniques by developing case-based reasoning (CBR) methods that employ collaborative filtering style ratings profiles directly as cases. Doing so presents a number of challenges, both in applying ...

This conceptual paper considers in some detail Nonaka’s Dynamic Theory of Knowledge Creation. Especially the concept of Ba or Basho is explored to figure out its applicability as an alternative view of learning in Collaborative Networked Organisations (CNOs).

In this paper, we describe a collaborative filtering approach that uses features of users and items to better represent the problem space and to provide better recommendations to users. Features of the collaborative filtering dataset are found and incorporated into a network representation of the collaborative filtering space where users and items are represented by nodes and where the nodes ar...

In this article we introduce the main research lines concerning CSCW and groupware, which are forming the core foundation of Collaborative Working Environments (CWE). Furthermore, we introduce the problematic aspects in CWE and the features and recommendations for the integration of CWE in organizations. Through this issue readers will learn new paradigms for the building of CWE as well as dire...
