Exhibition of old websites to mark International Museum Day

by
Heritales Crowd-Recycling e Arquivo.pt no Dia Internacional dos Museus

May 18, International Museum Day, was celebrated all over the country with free admission, guided tours, entertainment and exhibitions related to memory and heritage.

Arquivo.pt contributed with an exhibition of old web pages, entitled “Digital Memory through the Internet of the Past”, which was on display at one of the stands at the National Coach Museum in Lisbon.

The pages were selected to show different aspects of the Alentejo over time. From 2016, pages relating to the Heritales project were selected.

Heritales and Crowd-Recycling drew attention to the preservation of the Internet’s memory

Heritales is a project based in Évora that aims to study and disseminate heritage in all its manifestations. It is known for its main event created in 2016, HERITALES – International Heritage Film Festival.

Crowd-Recycling is a project focused on good practices for sustainability.

Heritales, Crowd-Recycling and Arquivo.pt carried out this action in collaboration with the aim of giving visibility to content published on the web over time. Preserving and giving access to digital content is fundamental to enhancing heritage.

Why an exhibition of old websites is a good idea

Making an exhibition of websites over time is relatively easy, all you have to do is come up with a theme, which can also be the history of an institution, and choose pages preserved on Arquivo.pt.

An exhibition of old websites is an original idea for the target audience. It often features texts and images that only existed on the web.

By drawing attention to the websites, we realize that many things were left unrecorded and this changes our view of the content we publish today. We start taking more care to save important pages, for example by taking action or saving them on the spot with SavePageNow.

World Internet Day was on May 17th

The day before International Museum Day was World Internet Day (May 17). The proximity of the two commemorations ties in with the theme of preserving memory.

Portugal connected to the Internet for the first time in 1991, with the FCCN project “RCCN IP Service”.

To remember how it all happened, here are the three suggestions that FCCN published on social media for this day:

#1 Arquivo.pt catalog of tools for digital preservation

Information that rules modern-day lives is born-digital and disseminated online. However, invaluable digital objects published online have been continuously lost.

Arquivo.pt is a public infrastructure which supports the preservation of digital objects published online to safeguard this digital legacy for future generations.

Thus, in October 2023 after 15 years of research and development, Arquivo.pt released a Catalog of 13 innovative tools to support the preservation of at-risk online content, from acquisition to dissemination (e.g. search and access, APIs, training, open data sets, exhibitions).

Arquivo.pt safeguards online digital objects of worldwide interest for research and education.

The Arquivo.pt Catalog was selected as finalist to the Safeguarding the Digital Legacy Award.

#2 Searching preserved web-images

Images published online are precious digital assets that document contemporary times for future generations.

This initiative describes the research and development of an innovative image search system that enables the discovery and access to billions of preserved images acquired from the web since the 1990s.

This research was applied to enhance the Arquivo.pt web archive with an image search service publicly available to any Internet user, officially launched in August 2022.

The resulting scientific and technical publications are available in open-access and the developed software is available as free open-source to be reused and enhanced by the community.

This work on searching images preserved in web archives applied for the Research and Innovation Award.

Analysis of the Arquivo.pt query dataset

by
demo-wordcloud-arquivopt3

Last updated on December 10th, 2024 at 03:12 pm

Arquivo.pt query logs are unique resources for research

Arquivo.pt provides a “Google-like” service that enables searching pages and images collected from the web since the 1990s. Notice that Arquivo.pt search complements live-web search engines because it enables temporal search over information that is no longer available online on its original websites.

Analyzing user behavior is an important research topic to understand users’ information needs and enhance the quality of search results. Thus, when a user interacts with a search engine, the system records the user’s actions in a file called the query log. Query logs from web archives are unique resources for research because they describe the real needs of web-archive users about the historical information published online over time.

Research case study

Flavie Gallois and Adam Jatowt from the University of Innsbruck, and Ricardo Campos from the University of Beira Interior and INESC TEC analyzed user search behavior based on the Arquivo.pt search query log dataset collected over a period of 3 months from June to September 2021 (Analyzing User Search Behaviour in Temporal Web Repositories through Search Query Log Analysis).

This study analyzed query features such as length, type or frequency and compared the obtained results with previous work about user search behavior over web-archives and live-web search engines.

This study revealed interesting trends and patterns about how users search for information within web archives, with strong potential for future research work.

How do web-archive users search?

Figure 1 : Distribution of country origin of users
Figure 1 : Distribution of country origin of users
Figure 2: Distribution of languages used in queries
Figure 2: Distribution of languages used in queries

The users came from Portugal in 85.7% of the queries. However, the Portuguese language was identified through automatic language identification of queries as being used in only 37% of the queries. This suggests that users apply other languages than their own to search in web archives.

Users of Arquivo.pt tend to use longer queries with more words and characters in comparison to previous studies, both over web archives and live-web search engines. About 92% of the queries had 5 or fewer terms (average of 25 characters), with 3 being the most common number of submitted terms. In previous work about search behavior in web archives, it was observed that users tended to submit from 1 to 3 terms per query, with 1 term as the most common submission.

Users tend to issue multiple queries within a session instead of a single query, possibly indicating a need for refining their search queries or exploring multiple options for inquiry.

87,7% of the queries submitted to Arquivo.pt used Desktop Browsers, despite Arquivo.pt providing mobile-friendly user interfaces. Old web-archived pages are not responsive and render poorly on mobile devices. Thus, it is expectable that users mostly use web archives through their desktops.

Figure 3: Arquivo.pt users can refine the time span of their queries by using the From and To datepickers.
Figure 3: Arquivo.pt users can refine the time span of their queries by using the From and To datepickers.

Users refined the time span of the search (using the datepickers) in about 50% of queries which indicates awareness of temporal needs peculiar to web-archive usage. Interestingly, users modified the From datepicker more frequently than the To datepicker. Notice that keeping the default time span may fit the user information needs and does not necessarily indicate the lack of awareness about the existence of the function to define time span (peculiar to web-archive search).

Only a small percentage of users included specific years in their query terms (4%), potentially suggesting that in these cases the time span function was insufficient, or unnoticed by some users.

The obtained results suggest that users are more conscious of their information needs and have improved their search techniques to be more effective over web-archives instead of just using them out of curiosity as first-comers.

What is searched in a web-archive?

The authors of the study applied automatic named entity recognition over the user queries and derived a set of word clouds that graphically provide a glimpse of the most common information needs of Arquivo.pt users:

Evaluation Metrics for web-archive search

The first step to understand user behavior is to define evaluation metrics. Defining metrics is a powerful tool to set long and short-term goals to decide which new products and features should be released to the users.

We share a work-in-progress report which aggregates information about Web Archive Search Evaluation Metrics. This contributes to comparing users’ search behavior between live-web and web-archive search engines. Feel free to comment directly on the collaborative document or to contact us.

This report also provides a summary of references about previous work, query workflows and structure of the corresponding query logs produced by Arquivo.pt, to facilitate the work from the researchers to study these data sets.

Commemoration of the 50th anniversary of April 25 – the Portuguese revolution of 1974

by
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.

See the exhibiton: arquivo.pt/50anos25abril

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.

Participation in the 50 years of April International Congress

jornadas-fccn-2024-funchal-thumb

Last updated on November 27th, 2024 at 01:43 pm

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.
