Non-Functional Requirements (NFR) are subjective, interactive and relative, thus realizing the need for particular NFR is by itself a challenge. Furthermore understanding what the software must implement in order to cope with these needs may prove to be an even more challenging task. One way of addressing the need for help on NFR elicitation is the use of catalogues. However, it is not clear ho...

This paper reports on going work to explore the role of electronic product catalogues in design management and new opportunities offered by e-commerce applications related to building product information in the construction industry. An approach based on the performance-concept in order to facilitate product selection from e-catalogues is described. In this approach product selection is facilit...

In this paper we report an experiment that investigated the question of whether elementary school children have metaconceptual awareness of theory revision processes. Fiftytwo elementary school children (grades, 1, 3 and 5) were asked to select between phenomenological and scientific depictions of different astronomical phenomena and indicate which of these depictions were closer to “Reality” a...

Catalogue Services provide the discovery and location mechanisms that allow users and applications to locate data on Grids. Replication is a highly desirable feature in these services, since it provides the scalability and reliability required on large Data Grids and is the basis for federating catalogues from different organisations. Grid Catalogues are often used to store sensitive data and m...

Astronomers are good at sharing data, but poorer at sharing knowledge. Almost all astronomical data ends up in open archives, and access to these is being simplified by the development of the global Virtual Observatory (VO). This is a great advance, but the fundamental problem remains that these archives contain only basic observational data, whereas all the astrophysical interpretation of that...

The FRBR model is by many considered to be an important contribution to the next generation of bibliographic catalogues, but a major challenge for the library community is how to use this model on already existing MARC-based bibliographic catalogues. This problem requires a solution for the interpretation and conversion of MARC records, and a tool for this kind of conversion is developed as a p...

We describe the construction of catalogues of galaxy clusters from the APM Galaxy survey using an automated algorithm based on Abell-like selection criteria. We investigate the eeects of varying several parameters in our selection algorithm, including the magnitude range, and radius from the cluster centre used to estimate the cluster richnesses. We quantify the accuracy of the photometric dist...

This paper presents preliminary research results on using semantic technologies to model Earth observation satellite data. The research goal is to enhance the data search functionalities that satellite data catalogues provide to researchers and practitioners. An ontology that captures characteristics of satellite data is introduced. How to utilize this ontology in assisting data search and how ...
