This paper introduces a method to cluster graphs of semantically related terms from texts using PageRank calculations for use in the field of text mining, e.g. to automatically discover different topics in a text corpus. It is evaluated by providing empirical results of tests by applying this method on real text corpora. It is shown that this application of the PageRank formula realizes suitabl...

framework. Since open source communities do not seem to get very far without a working version of the programme, virtually all authors are likely to have some features of the user-author. It is worth preserving this distinction however, as a way of keeping track of the distinction between the self-interest and collective interest motives of the participants. We may expect that the individuals w...

A particular strength of agile approaches is that they move away from ‘introverted’ development and intimately involve the customer in all areas of development, supposedly leading to the development of a more innovative and hence more valuable information system. However, we argue that a single customer representative is too narrow a focus to adopt and that involvement of stakeholders beyond th...

Being lost in space and overloaded with information are two key problems users are confronted with, when searching for appropriate information. Trails built from information about the users’ browsing paths and activities, are an established approach to assist users in navigating vast information spaces. However, existing trailbased systems are focusing on browsers only and therefore do not full...

The successes of open source software development have inspired commercial organizations to adopt similar techniques in hopes of improving their own processes without regard to the software process context that provided this success. This paper describes a reference framework for software process discovery in open source software development communities that provides this context. The reference...

INTRODUCTION Although stability of anterior open-bite extraction and nonextraction treatment has been investigated, results suggesting that extraction treatment is more stable have not been confronted. Therefore, the purpose of this cephalometric study was to compare the long-term stability of anterior open-bite extraction and nonextraction treatment in the permanent dentition. METHODS Group ...

Open Source Software development is seen as a panacea by many companies. The promise of community-style development, innovation and cost savings drive the wider adoption of OSS in companies. However, it is still difficult to institutionalize the open and agile culture of sharing innovation especially into larger departmentalized organizations. The aim of this research paper is to investigate th...

Product line engineering improves the management of variability and reuse in embedded systems. It helps to exploit mass customisation leading to individualised products to the customer. It has lead to heavy development processes and many global planning for a complete range of products (a product line). Open source development does not have a strong impact in embedded systems companies, partial...

This paper presents a discussion on the use of the DEVS formalism with the goal of studying how DEVS (or one of its derivatives) could support sharing modeling patterns. We address this open issue and present a discussion of this field that can be addressed by the DEVS community. On one hand, we describe the benefits and possible uses of sharing sub-components for component-based modeling; on t...

Due to the immensity of phylogenetic tree space for large data sets, researches must rely on heuristic searches to infer reasonable phylogenies. By designing meta-searches which appropriately combine a variety of heuristics and parameter settings, researchers can significantly improve the performance of heuristic searches. Advanced language constructs in the open-source PSODA project—including ...
