In 2005 the National Library of Portugal in collaboration with INESC conducted a series of web crawls to gather information related to the national elections.

This project was named RECOLHA and the data collected comprised over 14 million contents (165 GB).

In 2009 these data was supplied to the Portuguese Web Archive.

It was successfully integrated and now it can be searched through our experimental search system.

Notice, that searches are performed over all the archived data, independently from their origin, so you will not be able to identify the RECOLHA contents.

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.
