Knowledge practices mirroring is one of the central elements of the Trialogical Learning Approach as it is supposed to be a driving force in processes of practice transformation and knowledge creation. The exploitation of historical logging data holds promise to provide a great deal of information about group activities without requiring additional efforts(More)
This paper presents specialized methods for analyzing knowledge creation processes and knowledge practices that are (at least partially) projected in work within a virtual collaborative environment. Support for such analysis and evaluation of knowledge creation processes is provided by historical data stored in a virtual working environment, and describes(More)
The paper focuses on the domain of user behaviour evaluation in the collaborative processes performed in a virtual user environment. Proposed historical projection of activities performed in such an environment provides several analytic perspectives materialised in form of different tools, but all of them are based on suitable visualization and extraction(More)
This paper focuses on information retrieval aspects of a new application in domain of collaborative systems based on utilization of semantic principles for representation of different types of knowledge, collaborative objects and relations between them. Proposed collaborative system (within European IST project called KP-Lab1) uses ontologies as common(More)
This paper presents proposed solution for analyses of performed actions within a virtual intelligent and interactive environment. Investigated environment provides important functionalities that are based on principles of Ambient intelligence paradigm, i.e. context awareness, personalized and adaptive environment, or access through mobile devices. All(More)
This paper describes basic features of a client library called Persistence API that provides access point to knowledge repositories based on RDF standard. Persistence API (P-API) has been implemented within FP6 IST project called Knowledge Practices Laboratory in order to separate business logic from data representation in RDF. This approach enables simple(More)
In the article presented we deal with an innovative approach to collaborative work and learning. This approach is called trialogical learning and has emerged from several theories that describe the creation of new knowledge, e.g. Carl Bereiter’s knowledge building approach, Yrjö Engeström’s theory of expansive learning based on Activity Theory and Nonaka(More)
This paper presents an approach in the domain of collaborative systems for working and learning practices called KP-Lab System. This system provides integrated multifunctional application with interesting end-user functionalities as manifold semantic based manipulation possibilities with shared objects of activities in real time, a support for management(More)
The paper presents an interesting approach on how to identify crucial patterns in investigated collaborative processes that lead to critical moments. These critical moments represent positive or negative events with strong impact on the related process. In both cases identified patterns can be used for improvements and modifications in similar processes,(More)
