This paper was provided as technical input to the gap analysis of the UK escience programme, March 2003. The paper outlines generic requirements for security in grid systems and the problems that are often cited with current grid software. It is argued that these issues can be resolved by the federation of both users and resources. This concept of federation extends beyond user identity systems...

One solution to process and analysis of massive graphs is summarization. Generating a high quality summary is the main challenge of graph summarization. In the aims of generating a summary with a better quality for a given attributed graph, both structural and attribute similarities must be considered. There are two measures named density and entropy to evaluate the quality of structural and at...

In terms of statistical ideas, I would make a very broad distinction between two prominent sets of problems at this conference. First there are a number of problems in which the main feature is a very large amount of data, requiring new methods and considerable computing power. An example that has already been used with success in astronomy is the use of false discovery rates in problems involv...

A software engineering standard is an aid for systematic software development and process improvement. Because of the informal representation of software engineering knowledge, the document might be inconsistent, ambiguous, and incomplete. A more formal representation promises to overcome these shortcomings. Software process modeling is a direction within software engineering that aims at provi...
