The Apollonian metric is a generalization of the hyperbolic metric introduced by Beardon [2]. It is defined in arbitrary domains in Rn and is Möbius invariant. Another advantage over the well-known quasihyperbolic metric [8] is that it is simpler to evaluate. On the downside, points cannot generally be connected by geodesics of the Apollonian metric. This paper is the last in a series of four p...

For evaluating web applications (WebApps) and other entities in a systematic way an integrated measurement and evaluation (M&E) strategy is a valuable asset in any organization. We regard a M&E strategy is integrated if three coexisting capabilities are supported, namely: i) a conceptual framework, ii) a process specification, and iii) a methodological support. Under this premise, we conducted ...

The evolvability of software systems is one of the key issues when considering their long term quality. Continuous changes and extensions of these systems are neccessary to adjust them to new or changing requirements. But the changes often cause quality deficiencies, which lead to an increase in complexity or an architectural decay. Especially quality deficiencies within the specification or th...

Various commercial and scientific applications require analysis of user behaviour in the Internet. New web user sessions classification method is the main goal of proposed research. In this paper web usage analysis is described. Previously Levenshtein metric was applied to web sessions domain in hierarchical clustering. Test results show that the proposed clustering method has good accuracy in ...

For the improvement of software quality and productivity, organizations need to systematically build up and reuse software engineering know-how, promoting organizational learning in software development. Therefore, an integrated support platform has to be developed for capturing, storing and retrieving software engineering knowledge. Technical support is complicated through specific characteris...

Chinese Input Method Engine (IME) plays an important role in Chinese language processing. However, it has been subjected to lacking a proper evaluation metric for a long time. The natural metric for IME is user experience, which is a rather vague goal for research purpose. We propose a novel approach of quantifying user experience by using keystroke count and then correspondingly develop a fram...

Creating linguistic summaries of data has been a goal of the artificial and computational intelligence communities for many years. Summaries of written text have garnered the most attention. More recently, creating summaries of imagery and other sensed data has become important as a means of compressing large amounts of data and communicating with humans. In this paper, we consider the question...

This paper provides a a framework to evaluate the transition to a OSS software solution in terms of returns and losses in the context of Public Administrations. The ultimate goal of the framework is to identify costs that are not easy to trace or that are not usually collected like user acceptance. The framework has been conducted using a Total Cost of Ownership approach, which is the most freq...

Imitation is not only a powerful means to drastically downsize the exploration space when learning behavior. It also helps to align the learning efforts of a robot group towards a common goal. However, one prerequisite in imitation, the decision of which robot to imitate, is often factored out in current research. In our work we address this question by providing a means to measure the similari...
