The growing popularity of the World utilize Internet services as means of maximizing their profit by promoting products and services. Electronic commerce, which is also known as e economic environment in which business activities, such as purchasing products and advertising goods, are performed by using electronic communications. Web interface design is an important ‘pull factor’ in ecan be det...

This paper discusses some of the problems designers face in building catalogues in large networks and relates them back to the resource discovery problem. Currently many catalogues tend to be built in an adhoc fashion – which leads to a great variety in the quality of publically accessible network catalogs. Furthermore, the research surrounding these catalogues tends to focus on narrow technica...

We apply simple optical and SZ cluster finders to mock galaxy catalogues and SZ flux maps created from dark matter halos in a (1 hGpc) dark matter simulation, at redshifts 0.5 and 0.9. At each redshift, the two catalogues are then combined to assess how well they can improve each other, and compared to several variants of catalogues made using SZ flux and galaxy information simultaneously. We u...

We present the results of applying automated machine learning techniques to the problem of matching different object catalogues in astrophysics. In this study we take two partially matched catalogues where one of the two catalogues has a large positional uncertainty. The two catalogues we used here were taken from the HI Parkes All Sky Survey (HIPASS), and SuperCOSMOS optical survey. Previous w...

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...

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...

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...
