The paper Arquivo e medição da web portuguesa (in Portuguese) about the archive and measurement of the Portuguese web was considered one of the best of the CIWAI-2008 conference.

This recognition was given to 3 of the 66 published works. The conference received 216 submissions.

The paper presents the Portuguese web archive project and a characterization of the Portuguese web obtained from a crawl performed in February 2008.

According to the obtained results the Portuguese web is composed at least by 56 million contents which correspond to 2.8 TB of data.

The authors were invited to publish an extended version of the paper in a scientific journal.

The researcher  Zeynep Pehlivan developed and published in open-source a software to facilitate research over the test collection for Web Archive Information Retrieval we developed.

The information published on the web is a resource of great historical value that must be preserved for future generations.

RARC is an application that enables anyone to contribute to preserve the web, by providing a little bit of disk space to store a backup copy of the archived information.

This way, if information is lost from the central repository due to, for instance, a natural disaster, it can be retrieved from the computers of the people that installed rARC.

RARC includes a screen saver that presents examples of archived pages. You can uninstall rARC or reduce the donated space whenever you want.

Comments and suggestions are most welcome.

The Portuguese Web Archive publishes a top of the most generous contributors and the approximate location of the backup copies.
