We downloaded a set of 150 million Web pages on a weekly basis over the span of 11 weeks. We then determined which of these pages are near-duplicates of one another, and tracked how clusters of near-duplicate documents evolved over time. We found that 29.2% of all Web pages are very similar to other pages, and that 22.2% are virtually identical to other pages. We also found that clusters of near-duplicate documents are fairly stable: Two documents that are near-duplicates of one another are very likely to still be near-duplicates 10 weeks later. This result is of significant relevance to search engines: Web crawlers can be fairly confident that two pages that have been found to be near-duplicates of one another will continue to be so for the foreseeable future, and may thus decide to recrawl only one version of that page, or at least to lower the download priority of the other versions, thereby freeing up crawling resources that can be brought to bear more productively somewhere else.","PeriodicalId":376743,"journal":{"name":"Proceedings of the IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices (IEEE Cat.

This metadata schemas, beside XML/RDF syntactic code, the content description schemes (ontologies, topic maps, thesaurus, etc.) and a set of protocols for information interchange, will be the protagonists of the Second Generation of the Web. This landscape will be reflected by this tutorial. Its specific aims are: To present an introduction to the metadata concept and application. To define the metadata role in Web systems and services, versus its role in global information retrieval by all the web search engines. To present the general principles for any metadata project, mainly metadata schemas assessment and selection. To reflect the metadata schemas, models and standards possibilities and their syntax and coding (HTML/XML/RDF), and their heterogeneity problems and the need of planning interoperability between different web information objects. To explain paradigmatic cases of metadata management in subject gateways, their particularities and prospective use.","PeriodicalId":376743,"journal":{"name":"Proceedings of the IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices (IEEE Cat.
