Unwitting experimentation?

Badvertisements: Stealthy Click-Fraud with Unwitting Accessories

We describe a new type of threat to the Internet infrastructure, in the shape of a highly efficient but very well camouflaged click-fraud attack on the advertising infrastructure. The attack, which we refer to as a “badvertisement”, is described and experimentally verified on several prominent advertisement schemes. This stealthy attack can be thought of as a threatening mutation of spam and ph...

Exploratory Experimentation and Computation 1. Exploratory Experimentation

I believe our research community is facing a great challenge to re-evaluate the role of proof in light of the growing power of current computer systems, of modern mathematical computing packages, and of the growing capacity to data-mine on the Internet. Add to that the enormous complexity of many modern capstone results such as the Poincaré conjecture, Fermat's last theorem, and the Classificat...

BANCO: a Web Architecture Supporting Unwitting End-User Development

Today end users are no longer mere consumers of computer tools but increasingly need to be more active producers of information and software artifacts. New techniques for engineering software are needed to support end users in this new role. This paper introduces one of these techniques, namely unwitting end-user development, and explains the BANCO architecture, which has been designed to suppo...

GIR Experimentation

Geographic Information Retrieval (GIR) community has generally accepted the thesis that both thematic and geographic aspect of documents are useful for GIR. This paper describes a preliminary experiment exploring this thesis by seperately index-ing/searching geographical relevant-terms (place names, geo-spatial relations, geographic concepts and geographic adjacetives) extracted from reference ...
