Solomon: seeking the truth via copying detection

ABSTRACT

We live in the Information Era: the Web has enabled the availability of a huge amount of useful information and eased sharing of data among sources. Despite the richness of information surrounding us, an information user is often overwhelmed by the huge volume of raw, heterogeneous, and even conflicting data. Data sources can be of different qualities, providing information of different levels of accuracy, freshness, and completeness, and data can flow between data sources, being copied, reformatted, verified, and modified. There is an increasing need to help users find the information and the sources that are of highest quality and authority, to help data producers understand how their data are being used (and possibly protect their rights), and to help analysts and auditors understand how information has been disseminated and how rumors have been propagated [1].
