Research has shown that most users' online information searches are suboptimal. Query optimization based on a relevance feedback or genetic algorithm using dynamic query contexts can help casual users search the Internet. These algorithms can draw on...

Logical and physical design issues for smart card databases
Cristiana Bolchini, Fabio Salice, Fabio A. Schreiber, Letizia Tanca
Pages: 254-285
DOI: 10.1145/858476.858478
