The security, trust, information quality and privacy issues arising from the vision of the Semantic Web as a global information integration infrastructure are mainly unsolved.
This resource guide collects papers, ontologies, schemata and standards that might be building blocks for the future Semantic Web trust layer.
PGP and GnuPG have been utilizing webs of trust to establish authenticity without a centralized certificate authority for a while. Now, a new tool seeks to extend the concept to include scientific publications. The idea is that researchers can review and sign each others' works with varying levels of endorsement, and display the signed reviews with their vitas. This creates a decentralized social network linking researchers, papers, and reviews that, in theory, represents the scientific community. It meshes seamlessly with traditional publication venues. One can publish a paper with an established journal, and still try to get more out of the paper by asking colleagues to review the work. The hope is that this will eventually provide an alternative method for researchers to establish credibility.
Web spam pages use various techniques to achieve
higher-than-deserved rankings in a search engine’s
results. While human experts can identify
spam, it is too expensive to manually evaluate a
large number of pages. Instead, we propose techniques
to semi-automatically separate reputable,
good pages from spam. We first select a small set
of seed pages to be evaluated by an expert. Once
we manually identify the reputable seed pages, we
use the link structure of the web to discover other
pages that are likely to be good. In this paper
we discuss possible ways to implement the seed
selection and the discovery of good pages. We
present results of experiments run on the World
Wide Web indexed by AltaVista and evaluate the
performance of our techniques. Our results show
that we can effectively filter out spam from a significant
fraction of the web, based on a good seed
set of less than 200 sites.
