Reference implementation for open scientometric indicators (ROSI)

Field normalization of scientometric indicators

When scientometric indicators are used to compare research units active in different scientific fields, there often is a need to make corrections for differences between fields, for instance differences in publication, collaboration, and citation practices. Field-normalized indicators aim to make such corrections. The design of these indicators is a significant challenge. We discuss the main is...

Digipoe: an Open Standard and Reference Implementation for Digital Portfolios

In this paper we present the design and implementation of a software system aiming at helping educators in the process of appraisal for self-improvement and self-evaluation. The system is a "Digital Portfolio Environment" (DigiPoE) that allows the user to construct a comprehensive view of his/her work and enable the insertion and maintenance of multimedia content and artifacts into the portfoli...

Concentration and evenness measures as macro - level scientometric indicators - - - -

There exist different types of concentration and evenness measures. What they have in common is the fact that they all try to measure inequality. We will discuss only concentration measures that describe the scatter of items over sources, and this irrespective of the number of sources considered. Concentration measures can, e.g., be used as indicators for the convergence, or divergence of regio...

A Reference Implementation for UML

In this paper, we consider the problem of building a reference implementation (RI) to support a proposed semantics for UML . The purpose of the RI is to enable the automated exploration of the semantics and to permit tool vendors to verify tool compliance. In doing so, we consider the support required to implement UML profiles; specific extensions of UML that are based on a common semantic core...
