Special collection of web content on the Presidential Elections. We need your help!

Presidenciais 2026 -logo-PR2026-thumbnail

Last updated on March 13th, 2026 at 11:30 am

The 2026 Portuguese presidential election took place between January 18 and February 15. Arquivo.pt collected 2.3 terabytes of electoral content and now provides data on the entire process, such as search terms, identified content, and archived content.

The 2026 Presidential Elections took place in two rounds, the first on January 18 and the second on February 8, followed by a second round in 20 parishes, in the wake of the storms that ravaged the country. Thus, it is expected to find news about the affected areas as well as the political interventions of the presidential candidates in the collection.

Call for community participation in identifying and archiving election-related content

On January 15, Arquivo.pt invited the community to participate in collecting information about the elections: “Candidates’ websites, news articles, opinion columns, or social media posts—everything is useful for representing our life in democracy. Have you found interesting election-related content? Participate in identifying and archiving election-related content.”

Two modalities were suggested:

Arquivo.pt methodology for thematic coverage of the elections

Following the practice adopted in previous elections, the procedure consisted of the following steps:

  • definition of search terms
  • identification of search engine results pages (SERP)
  • phased recording of seeds (starting addresses for crawler use)
  • integration into Arquivo.pt
  • availability of data set

A search term is a combination of words used in a search engine. For example: candidate_name+presidential_elections 2026+Portugal.

Google was used to identify electoral content, and the Google Rank Checker,Keyword SERP Ranking Tool were also used to extract the results. The limitations recently imposed by the search engine on simple manual searches of results by a user (10 at a time) make this method less efficient.

The recording was phased as follows: before and after the first round, on January 12 and 23, before and after the second round on February 5 and 12, and a final recording of all seeds on February 18.

The result was 2.3 terabytes of data, comprising 11.4 million files, obtained from approximately 34,000 seeds using Heritrix and Browsertrix-crawler.

The contents are archived in the collection with the ID EAWP51 collection and will be accessible on the Arquivo.pt interface after one year. For now, information about searching and identifying content is available.

Thematic collections to discover in the online sessions “Café with Arquivo.pt”

cafe-with-arquivo-pt-squaree en

Last updated on March 31st, 2026 at 01:05 pm

“Café with Arquivo.pt” consists of short online sessions so that anyone can attend during working hours. Its aim is to raise awareness of Arquivo.pt and gather contributions from the community on topics related to web preservation.

In December 2025, a new series was launched dedicated to the thematic collections that Arquivo.pt publishes as datasets on the Dados.Gov open data platform. For example, websites related to theater, music, schools, parishes, elections, and other topics are preserved in the Arquivo.pt. We aim to highlight sets of websites whose history is preserved in the Arquivo.pt to improve their preservation.

Next session

April 15 – Replacing “Coffee with Arquivo.pt”, an online session in collaboration with the Bridges – Ponte Cultural project, CIDEHUS, Universidade de Évora, dedicated to the topic of “Immigration.”

The work Narrative Monitoring: Analysis of Conspiracy Theories on Population Replacement in the Portuguese Web Archive (1996–2021), which placed third in the 2025 Arquivo.pt Award, authored by Erik Bran Marino, Rafael Prezado, Ana Sofia Ribeiro, and Renata Vieira, will be presented.

Arquivo.pt is contributing to this session by presenting a special collection on the topic, collected this month.

Guest speakers: Erik Bran Marino, Rafael Prezado

Held sessions

24/03/2026 – Feminist activism and digital memory: archival practices and fragile data

Materials

Summary

The online sessions “Coffee with Arquivo.pt” aim to raise awareness of efforts in Portugal to preserve content published on the Internet and to encourage participation by researchers and the public. The highlight of this session is the project “FEMglocal – Glocal Feminist Movements: Interactions and Contradictions.” A theoretical framework will be presented, followed by a presentation and discussion of the results and activities carried out. For example, identifying websites and other digital channels used by feminist movements has yielded a useful dataset for studying the topic. This raises the question: how can we archive all this fragile digital content circulating on the Internet? As a contribution from Arquivo.pt, we will briefly demonstrate how to collect thousands of pieces of content published on the Web about a specific topic—for example, feminism.

“FEMglocal – Glocal Feminist Movements: Interactions and Contradictions” (PTDC/COM-CSS/4049/2021 / DOI 10.54499/PTDC/COM-CSS/4049/2021), a project funded by national funds through the FCT — Foundation for Science and Technology, I.P. With the participation of DivIntLab (CICANT). With the participation of the DigiPlArt Exploratory Project (2024.13064.PEX), also funded through the FCT.

Anotação de resultados de pesquisa no Arquivo.pt

Last updated on November 7th, 2025 at 03:55 pm

Anotação de resultados de pesquisa no Arquivo.pt

On World Digital Preservation Day, Arquivo.pt is promoting an online session dedicated to annotating search results on Arquivo.pt.

On World Digital Preservation Day, Arquivo.pt promoted an online session dedicated to annotating search results on Arquivo.pt, on 6 November, from 3 p.m. to 4 p.m.

The following topics were covered:

i) Access as a priority – text search as a search engine for the past
ii) How archived content is processed
iii) Annotations as quality assurance – demonstration

Importance of ranking results

The Arquivo.pt team has been reimplementing text search on Arquivo.pt, but needs to measure the quality of the new implementation by comparing it with the previous one. To do this, it is calling on the community for help.

How to rank results on Arquivo.pt

1. Acess to: https://anota.arquivo.pt

2. A random survey will appear (in Portuguese).

Example: “cavalo lusitano” “Associação Portuguesa do Cavalo Puro Sangue Lusitano” Entre 6 de agosto de 1991 e 1 de janeiro de 2010

3. Indicate the relevance of the result by selecting one of the buttons:

Annotation buttons: Very relevant, Partially relevant, Not relevant, Inaccessible content.

4. After finishing your annotation session, you should ‘Export’ (using the button for this purpose, which will download a file annotations.json).

5. Submit by clicking the ‘Enviar’ (Submit button and uploading the annotations.json file. Alternatively, you can send it by email to contacto@arquivo.pt.

Please refer to the guide (Guia de anotação de resultados de pesquisa) for a complete list of instructions.

Dataset on 2025 Portuguese Local Elections at Arquivo.pt

Last updated on December 3rd, 2025 at 12:56 pm

Local elections (“autárquicas”) were held in Portugal on 12 October 2025, and Arquivo.pt compiled a special collection of electoral content published on the web, resulting in 3.5 terabytes of information for research and academic work.

440 search terms were used to obtain 43,000 page addresses, along with the websites of parishes, municipalities, and political parties.

Here we explain the various steps involved in collecting data on the elections:

How to identify election-related content on the web

To identify content related to the elections, we used a list of search terms, for example, “eleições autárquicas 2025″, “habitação autárquicas 2025″, “promessas “autárquicas 2025”. After the elections, other terms were added, such as “vitória autárquicas 2025”, “resultados autárquicas 2025”.

The search terms are words that aim to include various topics related to the elections, such as politics, society, economics, among others, media, candidate names, and regions of the country.

In the collection on local elections, the Google search engine was used to perform each search. Some advanced search parameters were used: number of results (&num=100), news results (&tbm=nws), image results (&udm=2). After the elections, the results were restricted using the “last week” filter.

In each search, the addresses of the search engine results pages (SERP) were extracted using the Google Rank Checker,Keyword SERP Ranking Tool. This tool works as a browser extension that exports the list of results in JSON format.

In total, 1,400 searches or queries were performed on Google (800 before the elections and 600 after the elections). Finally, the results of all searches (.json files) were compiled into a document and converted into a table. Each result contains various data, such as relevance, the domain from which it was extracted, the link or URL, the title of the publication, the date of the search, and the query.

It should be noted that the list obtained represents only a small portion of everything published on the Web about the elections. In addition, the same list contains results unrelated to the purpose of the collection (false positives) and some repetitions. To save time, no lines were deleted.

This exercise resulted in 45,000 pages (seeds) with news, articles, and publications related to the elections to be used in the collection process by Arquivo.pt. This dataset, 2025 Local Elections, is available on the open data platform Dados.Gov.

A list of parish councils, municipal councils and political parties with their respective websites has also been added.

How the contents were recorded and limitations to be taken into account

The addresses obtained before and after the elections were recorded in two web crawlers, Heritrix and Browsertix-crawler . These tools record pages from a given starting address (seed), then follow the links there, up to a certain limit, in this case a maximum of five times (five hops).

Heritrix was used for an initial generic collection of pages, as it is capable of quickly processing lists containing thousands of addresses: 25,858 URLs before the elections and 17,258 URLs after the elections. It generated 541 gigabytes of information.

The Browsertix-crawler was used to improve the collection of dynamic content. This crawler’s recording is browser-based. Recording takes longer, but captures content that would otherwise escape collection.

The collection was carried out using the Browsertix-crawler, in stages, first by recording the parish websites in August and September, and then, between October 9 and November 5, by recording news about the elections and 8,850 social media posts. It generated 2.9 terabytes of information.

As for the limits of the collection, we were able to identify a few: access blocked by some websites that defend themselves against automatic access, despite the Arquivo.pt agent being identified; social media content behind a login that cannot be reproduced on Arquivo.pt; videos that cannot be reproduced due to their format.

How and when to access data for research and work creation

EAWP48 is the identifying name of the collection that will bring together content on the Local Elections of 12 October 2025. It is described in the list of collections at Arquivo.pt.

Nos próximos meses, o conteúdo será indexado e os índices CDXJ ficarão disponíveis para os investigadores na lista de datasets do Arquivo.pt.

In the coming months, the content will be indexed and the CDXJ indexes will be available to researchers in the Arquivo.pt dataset list.

After one year, the collected content will be accessible through the Arquivo.pt search engine. Anyone will then be able to search election pages by text or image.

For further information, please contact us.

Data collected on the 2025 Local Elections

2025 local elections have a special collection at Arquivo.pt

Local elections will be held in Portugal on 12 October 2025 (Eleições Autárquicas), and Arquivo.pt will launch a special collection of electoral content.

Whenever elections are held, websites and social media channels are created for electoral purposes, many of which are deactivated shortly afterwards.

Sometimes, publications made during the election campaign disappear and it is not possible for citizens to see them again or for researchers to use them for study and analysis.

Arquivo.pt invites you to archive pages about the local elections. It’s simple: copy and paste an address and archive it. Here:

Alternatively, send us the link and we will record it.

The winners of the Arquivo.pt 2025 Award were announced by the Público newspaper, the official media partner, on 28 June 2025.

A total of 36 entries were received and validated.

The award ceremony took place at the closing session of Encontro Ciência, at the NOVA School of Business and Economics (NOVA SBE) campus in Carcavelos, Lisbon, on July 11, 2025.

Start preparing your work for 2026 now!

The rules for the 9th edition of the Arquivo.pt Award were published in the Diário da República on 29 September 2025. Further information will be published shortly. The form for submitting works will be available in the first week of January and will close on 6 May 2026.

See the previous winners and compete with an innovative work.

1º place – “Minha Região – O Teu Portal Autárquico”

The winner of the 10,000 euro prize was the work ‘Minha Região – O Teu Portal Autárquico’ developed by Rúben Almeida, Ricardo Campos and Sérgio Nunes.

The result of this work is a platform available on the web that gathers municipal electoral information between 1976 and 2021. Through the minharegiao.pt website, anyone can find information by district, municipality and parish.

For example, a search for the Braga district shows the rise in the number of voters over time. It also shows that 2013 was the year with the highest abstention rate.

News:

2nd place – “Memor.pt – Explore a Memória Digital Portuguesa”

The 2nd prize of 3,000 euros was awarded to the work ‘Memor.pt – Explore Portugal’s Digital Memory’, by Joaquim Matoso.

Memor.pt is an interactive platform that uses content preserved by Arquivo.pt to make Portugal’s digital memory accessible. Through a conversational AI, a themed quiz and a daily article, users can explore thousands of archived pages on topics such as housing, democracy, culture and the labour market.

For example, if you choose to ‘play’, you’ll have a choice of five topics to test your knowledge with a quiz. So, what year was the new Democratic Constitution approved after 25 April?

3rd place – “Narrative Monitoring”

The third prize of 2,000 euros was awarded to the work ‘Narrative Monitoring: Analysis of conspiracy theories of population replacement’, developed by Erik Bran Marino, Rafael Prezado, Ana Sofia Ribeiro, Renata Vieira.

The work ‘Narrative Monitoring’ is a systematic and comprehensive analysis of the emergence and evolution of conspiracy theories of population replacement (PRCT, Comparative analysis of conspiracy theories in Europe), in the Portuguese digital space, between 1996 and 2021. Using Arquivo.pt as a primary source, it develops a methodology that combines web archiving techniques, natural language processing and statistical analysis to identify, classify and analyse 36,621 documents related to migration and demographic issues.

The website www.narrativemonitor.uevora.pt presents the results through interactive visualisations, a dynamic timeline and an educational quiz on the keywords most associated with conspiratorial discourse. For example, ‘Multicultural’, ‘Kalergi Plan’, ‘Refugee’. Which of these keywords is most associated with conspiratorial population content?

Honorable mention AMCC – Aveiro Media Competence Center: “Estudos Arquivados”

The Aveiro Media Competence Centre (AMCC) has awarded its Honourable Mention to the work ‘Estudos Arquivados’, by Filipe Oliveira João and Paulo Cabrita.

‘Estudos Arquivados’ is a platform that uses Arquivo.pt for pedagogical and teaching purposes. It organises a user’s searches by subject and school year, and users can register and save their own searches for later use. In contexts where schools use technology for teaching, ‘Estudos Arquivados’, being based on a public and open collection, aims to promote study and digital inclusion.

For example, a survey on the ‘25 de Abril’ for 8th grade students (high shcool) in the subject of History returns dated web pages preserved on Arquivo.pt, training students to use this new type of material.

Honorable mention .PT: “ArchiveChain”

The DNS.PT Association has awarded an Honourable Mention to . PT to the Professor who encouraged the submission of ‘ArchiveChain’. This work was developed as part of Bruno Cotrim’s Master’s dissertation in Computer Engineering at the Faculty of Sciences of the University of Lisbon, with scientific guidance from professors Bernardo Ferreira (Faculty of Sciences) and Miguel Matos (Instituto Superior Técnico).

The concept is explained by its authors as follows: ‘ArchiveChain’ is a blockchain that democratises the mission of archiving the Portuguese historical web. In ArchiveChain, all citizens are invited to save pages from Arquivo.pt, and whoever saves the most pages receives the most rewards in the form of cryptocurrencies. At the same time, the pages saved by participants are used as ‘fuel’ in its internal workings, making it possible to implement smart contracts in a sustainable way and avoiding the massive energy consumption of other blockchains such as Bitcoin.

Start exploring the ArchiveChain platform and contribute to the better preservation of the Portuguese web.

News:

Honorable mention 25 de Abril e a Democracia: “Arquivo 25 de Abril”

The Comissão Comemorativa 50 anos 25 de Abril (Commemorative Commission for the 50th anniversary of 25 de Abril) awarded an Honourable Mention called ‘25 de Abril e a Democracia’ to the work ‘Arquivo 25 de Abril’, developed by Miguel Garcia.

The ‘‘Arquivo 25 de Abril’ website provides an online archive of journalistic articles about various personalities, events and movements that were relevant before and during 25 April 1974. For each of these elements, articles were collected from various leading media organisations, published online, taking this historical context into account.

For example, by choosing ‘artists’ related to 25 April, a user gets the name and a photo of singer Adriano Correia de Oliveira, the first in a list, and then related news published in the media and preserved by Arquivo.pt.

RESAW 2025 conference had the participation of Arquivo.pt

Arquivo.pt was present at the 6th RESAW Conference for researchers in the Digital Humanities, Media and Communication and other areas, on the theme of ‘The Datafied Web’, which took place at the University of Siegen, Germany, from 4 to 6 June 2025.

RESAW (Research Infrastructure for the Study of Archived Web Materials) is an informal initiative that brings together researchers who use web archives in their research. RESAW’s first conference was in 2015, and it is now held every two years.

Initially, RESAW brought together European researchers, but now it brings together researchers from all over the world and has become a unique forum of its kind. In 2025, it had more than 100 participants. It brings together the best in the field of using web archives in research.

Niels Brügger, Professor of Media and Communication at Aaharus University in Denmark, has been its main driving force for 10 years.

Other leading researchers with studies on web archives are: Valerie Schafer from the University of Luxembourg, Jane Winters from the University of London, Anne Helmond from the University of Utrecht, Susan Aasman from the University of Groningen, Sophie Gebeil from Aix-Marseille University and Ian Millingan from the University of Waterloo.

This year’s theme “The Datafied Web” addressed the issue of the datification of the Web, from its beginnings in the 1990s to the present day, marked by massive data processing and the use of Artificial Intelligence.

Why would a web archive take part in an academic meeting?

Arquivo.pt has been a regular participant in RESAW since 2019, as it wants to make itself increasingly known as a service for national and international researchers.

Thanks to participation in international events such as RESAW, several publications have appeared that use and refer to Arquivo.pt. Any researcher with Internet access can search the information preserved on Arquivo.pt, use the APIs, process information or train their models.

We invite Portuguese researchers to take part in this meeting, as we have been the only Portuguese presence in several editions. We have an accessible web archive, ready to use, which is not the case in other countries. We would like to see researchers in the fields of Digital Humanities and Media and Communication in Portugal using Arquivo.pt more often and actively participating in meetings like RESAW.

Arquivo.pt’s contribution to RESAW 2025

Arquivo.pt contributed two presentations to the 2025 edition of the RESAW meeting, held at the University of Siegen. The first was about the Arquivo.pt APIs and their application in a research context, by Vasco Rato. The second was about the open datasets and lists of websites on topics and events that Arquivo.pt has prepared to help researchers start exploring archived information in greater depth.

Arquivo.pt carried out a special collection of content published online in connection with the Legislative Elections of 18 May 2025.

More than 8,000 unique pages were recorded, before and after the elections, resulting in around 250 Gigabytes of information.

This collection includes news items from the media, party websites and other citizen publications documenting this important event in Portuguese life.

The data collected is available for researchers to use in their work and projects.

Methodology for collecting the electoral event

The collection was carried out using a semi-automatic methodology that allows information to be identified and collected quickly and saves resources. The steps were as follows:

  • preparation of a list of search terms;
  • automatic search with the Bing Search API;
  • extraction of a list of page addresses or URLs;
  • recording (using Browsertrix-crawler);
  • integration into Arquivo.pt;
  • making the dataset available for research.

The starting point for identifying pages for this electoral event was a list of search terms, including words, names, dates, website addresses and also words in other languages. For example, we used ‘eleições’ “legislativas”, 2025, candidate names, party websites, newspaper websites and ‘eleições Portugal’ in other European languages to find foreign media pages that referred to the Portuguese elections. A total of 384 search terms were used.

The extracted addresses or URLs are then recorded, assuming that there are pages that miss the target and favouring speed, an important factor in this type of event.

A search was carried out to identify web pages before the elections and two the following week, with the corresponding recording, in order to add new content to the collection.

Finally, all the data from this special collection was published. Researchers are invited to use this information for projects or studies and to compete for the annual Arquivo.pt Award.
