In knowledge management literature it is often pointed out that it is important to distinguish between data, information and knowledge. The generally accepted view sees data as simple facts that become information as data is combined into meaningful structures, which subsequently become knowledge as meaningful information is put into a context and when it can be used to make predictions. This v...

The hierarchy is often used to infer knowledge from groups of items and relations in varying granularities. Hierarchical clustering algorithms take an input of pairwise data-item similarities and output a hierarchy of the data-items. This paper presents Bidirectional agglomerative hierarchical clustering to create a hierarchy bottom-up, by iteratively merging the closest pair of data-items into...

A Generalized Temporal Role Based Access Control (GTRBAC) model that captures an exhaustive set of temporal constraint needs for access control has recently been proposed. GTRBAC’s language constructs allow one to specify various temporal constraints on role, userrole assignments and role-permission assignments. However, the presence of temporal constraints on role enablings and role activation...

Consideration of variation has been identified as one of the fundamental types of statistical thinking, and recent research into the understanding of variation highlights its growing importance. Curriculum needs to reflect this trend. This chapter proposes a model for an integrated approach to curriculum development where consideration of variation is used as the linking thread. The application...

Hierarchical channel structures are used to create granular sub-channels from a parent channel. Utilized in routing situations that are more or less static, they require that the channel namespace schema be both well defined and universally understood. The publish/subscribe messaging model currently requires a message publisher to place messages into a specific channel within the hierarchy. A r...

Generalized Temporal Role Based Access Control (GTRBAC) model that captures an exhaustive set of temporal constraint needs for access control has recently been proposed. GTRBAC’s language constructs allow one to specify various temporal constraints on role, user-role assignments and role-permission assignments. In this paper, we present the notion of different types of role hierarchies based on...
