50anos25abril-ArquivoPT-IG-Feed-2

Arquivo.pt joined the celebrations of the 50th anniversary of April 25, the Portuguese Revolution of 1974, as part of the initiatives promoted by the Fundação para a Ciência e a Tecnologia (FCT) in partnership with the Estrutura de Missão – Comissão Comemorativa 50 anos 25 de Abril.

The initiatives were as follows: a journey through time, a special collection on the theme “Abril 25”, a presentation at the “50 years of April International Congress” and the inclusion of a special mention in the 2025 edition of the Arquivo.pt Award.

Memories of April 25 on the Internet exhibition

The exhibition Memories of April 25 on the Internet presents a selection of web pages about the celebrations of April 25 in various regions of the country, since the beginning of the web in the 1990s.

The criteria for choosing the pages for the exhibition were as follows:

  • Pages relating to the April 25 commemorations;
  • Pages found on Arquivo.pt on dates close to the anniversary each year;
  • Diversity to include different areas of the country;
  • Popular demonstrations and official ceremonies.

A historical memory without web archives is incomplete. The aim of this journey through time is to invite citizens to travel back in time, browsing through old web pages and reliving recent episodes in our life as a democracy.

Special collection on April 25 – the Portuguese Revolution of 1974

To mark the anniversary, Arquivo.pt carried out a special collection on the topic of “April 25” and made the results available in an open dataset, published on the Dados.gov portal.

The dataset contains a list of keywords put into a search engine in order to obtain results on the topic of “April 25”. The search considered names of people, places, political, social and cultural aspects, as well as words associated with the event.

The searches were carried out on March 22, 2024 using the Bing Search API, an automatic search service that returns results according to the relevance criteria of the Bing service itself and others configured by us.

A total of 12,650 unique web page addresses were obtained. It is hoped that the recording of these pages will be useful for the organizations that produced this content, for researchers who want to study our history and for citizens who cultivate a sense of memory and democracy.

The Arquivo.pt team was in Funchal between April 15 and 19, 2024, and presented two different sessions on web preservation. The first took place during the Jornadas FCCN 2024 and the second was a workshop, after the event had ended, at the headquarters of the Regional Agency for the Development of Research, Technology and Innovation (ARDITI).

Arquivo.pt at Jornadas FCCN 2024

The session held during the Jornadas FCCN 2024 was entitled “Arquivo.pt at the service of culture” and aimed to highlight two of Arquivo.pt’s collaborations in the field of culture and knowledge, namely with Wikipedia Portugal and the Virtual Museum of Tourism (MUVITUR).

At the FCCN Zapping session, Arquivo.pt presented the Arquivo404 service, which allows websites to offer historical content instead of the negative “Page not found”.

Workshop with ARDITI

The post-Day Workshop, promoted by ARDITI, was open to regional institutions and citizens in general. It was entitled “Arquivo.pt and the preservation of Internet memory”.

The contents were structured according to the training program run by Arquivo.pt and preceded by a framework between the other services of the FCCN – FCCN – Computação Científica da FCT.

Just as important as the content was the dialog that was established during the sessions between the participants and the Arquivo.pt team to clarify doubts or ask questions.

Web preservation is increasingly important for organizations that want to preserve part of their institutional memory and develop security policies.

ARDITI gave an important signal about preserving the web memory of Madeiran institutions by hosting and promoting the Arquivo.pt training sessions.

If you want to promote the preservation of web content in your organization, check out the Arquivo.pt training and contact us.

Artificial Intelligence processes data from Arquivo.pt

by
Artificial Intelligence AI

Last updated on July 16th, 2024 at 08:33 am

Artificial Intelligence (AI), covers various areas of knowledge, such as linguistics and computing, and is present in the new technologies used by citizens on a daily basis.

For example, when we search for information on the Internet and the computer generates an amazingly accurate response, in a language very close to our own.

Natural Language Processing (NLP) is what allows machines to perfect the algorithm that generates these answers tailored to Internet users.

The problem is that natural language processing models have been developed more for the English language and less for Portuguese and other languages with less representation.

The more the processing models are trained on a language, the better they will be able to interpret the complexities of the language. But this is only possible if quality data is available.

Portuguese text collection on Arquivo.pt available for research

Arquivo.pt appears here as the largest Portuguese-language textual dataset in Portugal, available in open access, for researchers to train NLP models.

In recent years, researchers from various research groups and projects have drawn attention to the usefulness of preserved web data for large-scale processing.

Arquivo.pt has more than 1 Petabyte of preserved web content dating back to the 1990s, including everything that can be found on web pages. It’s not just text, but also images, audio files, video, page code and various metadata.

The content is accessible via the search interface and the Arquivo.pt APIs.

In order to make it easier to download archived resources from the web, Arquivo.pt has created indexes for researchers in CDXJ format.

GlórIA, a model for the Portuguese language

One of the projects that used Arquivo.pt to obtain large amounts of text is called GlórIA and is a large-scale language model (LLM) focused on the European Portuguese language.

“Despite the abundance of LLMs for many high-resource languages, the availability of such models remains limited for European Portuguese” as the authors of GlórIA project, Ricardo Lopes, João Magalhães, David Semedo, researchers at the NOVA School of Science and Technology, explain in their article GlórIA – A Generative and Open Large Language Model for Portuguese.

The model used 35 billion tokens, or expressions that machines can process, from various sources.

Arquivo.pt contributed a collection of 1.4M European Portuguese archived news and periodicals.

You can try generating text in European Portuguese using the GlórIA API inference on the Hugging Face Model card.

If you want to develop a project or study using Arquivo.pt, you can start your research and, if you need help, contact us.

Arquivo.pt reaches 1 PetaByte of preserved information!

by

The collection of 1 PetaByte of content predominantly in Portuguese, accessible to both researchers and ordinary citizens, is a milestone that deserves to be celebrated, in the month of its 16th anniversary.

At Arquivo.pt you can search for information published on the Web in the past, such as:

Discover more pages through the selected pages in the Arquivo.pt Online Exhibitions.

The first European page
News from The New York Times in 2008
European Film Awards 2014

Purpose and mission of the Portuguese Web Archive

Arquivo.pt was created on November 8, 2007 with the aim of preserving content from the Portuguese Web.

In 2013, as a service operated by the Fundação para a Ciência e a Tecnologia (FCT), its mission was formulated as follows: “To promote the preservation of content available on the national Internet, ensuring that it is made available to the scientific community and the general public” (Decreto-Lei no. 55/2013).

In recent years, Arquivo.pt has created new services, such as CitationSaver, which allows researchers to record references to web content in their scientific articles, Memorial and Complete page, which facilitate access to content scattered throughout the huge 1 PetaByte block of data.

Where did so much information come from?

In order to reach the 1 PetaByte volume, Arquivo.pt periodically recorded content from websites in the .PT domain and from Portuguese websites in other domains.

In addition, frequent daily and monthly collections were made from a small number of government sites and the main news sites in Portugal.

As part of international collaborations, content was collected from sites in various languages, for example on the 2019 European Elections.

Content prior to 2008 came from the Internet Archive and donations, such as a collection made by the National Library and INESC on the 2005 Legislative Elections.

The largest Portuguese-language dataset available to researchers

By making 1 PetaByte of information available, in open access and through the use of APIs (Application Programming Interfaces), Arquivo.pt is a useful tool for research.

For example, a researcher who wants to do a study on elections in Portugal can use the entire Arquivo.pt collection. Better still, they can focus on just a few special collections dedicated to the elections, choosing the ones that interest them and downloading just a few Terabytes to process automatically with the APIs.

Contributions from the various teams and friends of Arquivo.pt

The development of Arquivo.pt is more than a technological issue and has been due to the dedication and persistence of the various teams that have worked on it since 2007.

It was also due to the contribution of many friends of Arquivo.pt, who were always on hand to help improve, and to the response of the user community.

Congratulations to all! Thank you.

Arquivo404 more powerful!

by

Last updated on August 9th, 2024 at 12:59 pm

Arquivo.pt has been launching innovative complementary services useful for organizations to optimize their functioning.

The new release of Arquivo.pt named Helios was launched on November 13, 2023 and includes developments in Arquivo404 and CitationSaver.

Arquivo404 with new methods for defining time intervals

Arquivo404 is a service that presents website users with links to web-archived versions, instead of laconic “Page not found” error messages.

However, sometimes it is necessary to specify the correct version of a web-archived page to be displayed. For example, a website’s domain may have belonged to another entity in the past, and only web-archived versions since the website came under its current owners should to be displayed.

For this purpose, 3 new methods for configuring Arquivo404 were released :

  • setMinimumDate( minDate : Date ) – specifies the earliest date of the web-archived version of the URL that can be displayed.
  • setMaximumDate( maxDate : Date ) – specifies the latest date of the web-archived version of the URL that can be displayed.
  • setMostRelevantMemento( criterion : ‘oldest’ | ‘most-recent’ ) – specifies the order of results for the versions retrieved from the web archive. By default, the oldest version is displayed ( ‘oldest’ ).

In short, Arquivo404 now allows you to define whether to display the oldest or most recent web-archived page to the users, within a certain time interval.

CitationSaver processes HTML documents

CitationSaver is a service that extracts citations in documents to online resources and archives them. This service is particularly useful for maintaining the integrity of scientific articles and the reproducibility of the experiments and studies described in them.

Many open-access articles are published in hypertext format (HMTL). CitationSaver now processes documents in HTML format, in addition to PDF and TXT formats.

For example, if a user finds an article on the Web  which contains citations to online resources, he/she simply needs to submit the URL of the article into CitationSaver. The URLs cited in the article will be extracted and their content will be web-archived for later access.

Example of an article from the Journal of Integrated Coastal Management, available on SciELO

University of Lisbon preserved over 100 historical websites in the Arquivo.pt Memorial

by
thumb-memorial-fcul

Last updated on March 27th, 2024 at 11:17 am

More than 100 historical websites from the Faculty of Sciences of the University of Lisbon (FCUL) are now accessible through the Memorial service of Arquivo.pt.

FCUL’s IT Department sent to Arquivo.pt a list of old websites hosted on its servers that were no longer updated, but whose historical content continues to be interesting to the community (e.g. websites of research projects or scientific events).

Arquivo.pt preserved these websites in collaboration with their ownersa, seeking to maintain a faithful representation of the published content for the future.

FCUL redirected the domain of each website to Arquivo.pt, and then, became able to disconnect the respective servers and  begin sparing the resources spent on their maintenance (e.g. electricity, data center space, human resources).

The show case of MiNEMA

print-memorial-example-minema-project

Landing page of www.minema.di.fc.ul.pt at Memorial do Arquivo.pt.

The MiNEMA scientific program website was the first that FCUL integrated into the Memorial. This website stopped being updated in 2009 when the project ended. FCUL invested resources in maintaining the website for another 10 years until it became necessary to suspend it down for cybersecurity reasons.

The Memorial of Arquivo.pt emerged as an option and since 2020, FCUL just needs to maintain the domain www.minema.di.fc.ul.pt while Arquivo.pt preserveS the information contained on the website.

Please note that the website’s content continues to be displayed in search engine results.

Follow FCUL and preserve your historical websites in the Memorial!

An increasing number of institutions are recurring to the Memorial of Arquivo.pt to safely preserve the content of their historical websites. For example, FCUL preserved 116 websites, the Government IT Network Management Center preserved 23 and the Foundation for Science and Technology preserved 40.

Public institutions have priority to benefit from this service. However, other entities can also request it as long as they own the website domain.

Identify your historical websites candidate to be integrated into the Memorial of Arquivo.pt and contact us!
