In this paper we discuss background considerations, domain properties, and some design principles for collaborative modeling environments combining the Business Rule Management approach and the Collaborative Modeling approach. The context focused on is that of translating law texts to operational processes and systems for implementing those laws in the public sector. The process of operationali...

Organizations that work in strategic alliances, also known as Collaborative Networked Organizations (CNOs), learn with this experience. The whole learning process in which they are involved with is rich, creates value for the alliance and should be better explored in order to improve the CNO partners’ performance when facing new challenges. The core content of this work is related to the charac...

The primary application of collaborate filtering (CF) is to recommend a small set of items to a user, which entails ranking. Most approaches, however, formulate the CF problem as rating prediction, overlooking the ranking perspective. In this work we present a method for collaborative ranking that leverages the strengths of the two main CF approaches, neighborhoodand model-based. Our novel meth...

In this paper, we consider collaborative filtering as a ranking problem. We present a method which uses Maximum Margin Matrix Factorization and optimizes ranking instead of rating. We employ structured output prediction to optimize for specific non-uniform ranking scores. Experimental results show that our method gives very good ranking scores and scales well on collaborative filtering tasks.

Though discussion of the teacher factor in ICT-enabled science learning abounds in the literature, the investigation of Teacher Enactments (TEs) of ICT-facilitated lessons through exploring teaching practices is still under-explored and under-recognized. Current studies are still lacking in evidence-based findings of TEs based on the investigation of teaching practices. This study explores the ...

We present the results of a study1 in which we contrast alternative forms of collaborative learning support in the midst of a collaborative design task in which students negotiate between increasing power and increasing environmental friendliness. In this context, we evaluated the instructional effectiveness of four alternative support conditions as well as a goal manipulation. Both manipulatio...
