At #ACMHT2025 day 4, Yavuz Selim Kartal (from @gesis.org) discusses supplementing social media posts with AI-generated summaries, which are perceived as most understandable form of enrichment as compared to metadata enrichment or pull quotes. @acmht.bsky.social #HT2025 📄 dl.acm.org/doi/10.1145/...

Almost all participants in their interviews mentioned fairness in musicRecSys came down to paying the artists. Secondarily was alg. bias &popularity bias as interview insights. Not everyone agreed that imbalance in the sys meant it was unfair. Many also wanted transparency & control. #ACMHT2025

At Day 4 of #ACMHT2025, Karlijn Dinnissen describes the role of fairness & diversity in user choices and perception of music playlists. * What do end users think makes a fair MusicRec sys? * How does that impact their choices? * How should they be informed? #HT2025 📄 dl.acm.org/doi/10.1145/...

Ágnes Horvát highlights in her @acmht.bsky.social keynote that the frequency of certain words in PubMed abstracts has drastically increased due to authors massaging their texts with LLMs. #HT2025 #ACMHT2025

At the #HT2025 Day 3 keynote, Ágnes Horvát asks, "How is science effectively promoted in online social spaces? Does self-publicity online lead to a tangible increase in citations?" When we account for venue, popularity of authors, etc., there still seems to be a net positive.

In his #nht25 prez @ #HT25, David Millard (@hoosfoos.bsky.social) ids the parallels between hypertext & those that will come as a result of gen AI. Who controls meaning? What are the boundaries of text? We typically think of AI as an assistant, the human being's still the wordsmith.

@eastgate.bsky.social describes resurrecting Information Cities at #NHT25 as a narrative, a journey toward understanding, a central theme in open world games like Elder Scrolls or Cyberpunk 2077 #ACMHT2025 #HT2025 @acmht.bsky.social

They utilized the timestamp of a tweet to estimate the time that a tweet has been archived. They then established left & right time boundaries to limit search space to make resolving captured tweets from the web archive more efficient. @tarannum44.bsky.social #ACMHT2025 📄 doi.org/10.1145/3720...

1. Reconstruct a tweet URL based on the embedded parameters in a tweet 2. Search @archive.org. Web archives are most useful when the Tweet (or account) is no longer on the live web. - @tarannum44.bsky.social #ACMHT2025

Another reason fake tweets are shared is for satire. 100k likes and no comments is suspicious. How can you tell it's real? Web archives serve as a good src of evidence that it's real. Their goal is to build an automated method for evidence that a tweet is authentic @tarannum44.bsky.social #ACMHT2025

@tarannum44.bsky.social from @webscidl.bsky.social is up next at #ACMHT2025 describing web archives usage for verifying attribution of Twitter screenshots with a compelling use case of one's love for pineapple pizza. 🍍🍕 @phonedudemln.bsky.social

In his #ACMHT2025 talk, Mariusz Pisarski asks the questions about Google's AI integration into their search UI stating that research shows that users largely don't click on results at all, but instead rely on the provided summaries. Paper 🔗 dl.acm.org/doi/full/10....

Hashing the first few letters and having a linear search is a perfectly reasonable data structure and works well for a collection of thousands, probably better than a full sort. - @eastgate.bsky.social @ @human-ht.bsky.social #ACMHT2025

000

@eastgate.bsky.social @ @human-ht.bsky.social:The problem w/ dealing w/ lots of stuff: there's always more to read & more questions to pursue. Even in antiquity, we have people that used thousands of srcs. Ancient collections assume readers want multiple tellings & read against them. #ACMHT2025

At @human-ht.bsky.social at #ACMHT2025: @eastgate.bsky.social describes historical compression: We want to compress messages, because every bit is expensive. When your bits are inscribed in stone, they are really expensive. One tablet had very bad handwriting then tooth marks on the back side.

Words per pope: Andrezej Adamski discusses the inter-pope sentiment of popes in time at the HUMAN workshop (@human-ht.bsky.social ) at #ACMHT2025. Takeaway: phrases track the media environment of each era.

How would hypertext help for census date resolution? Cathy Marshall discusses in her @human-ht.bsky.social keynote at #ACMHT2025, "It's important to be able to back out records when Ruth isn't Paul's bio mother & that all her records should be deprecated. The cost for link-making is high and noisy."

Ida Haugen-Poljac used AI to identify hate speech and verbal attacks online using AI. #ipres2024

Håvard: "We are trying to get a better understanding of the broader trends and patterns that are occurring online. We don't look at individuals when we run our analysis." They look to Quantifying Hate, minority hate, online polarization, and election integrity. #iipcWAC25

basilesimon.bsky.social goes on in his #iipcWAC25 presentation to describe methods toward verifiability for evidentiary use. WACZ's cryptographic aspects help to facilitate this. #webarchiving

Basile Simon (basilesimon.bsky.social) starts off the "Handling What You Captured" session at #iipcWAC25 with "So You've Got a WACZ: How Archives Become Verifiable Evidence". He discusses three projects where open source information have informed real-world, investigate processes.

"Two thirds of the dead links on Wikipedia are rescued...", an unreliable claim from @ibnesayeed.bsky.social, ending with "...but don't quote me on that!" #webarchiving #iipcWAC25

@ibnesayeed.bsky.social (Internet Archive) rounds out the Advocacy & User Engagement session at #iipcWAC25 with "Lost, but Preserved-A #WebArchiving Perspective on the Ephemeral Web" with various assessments of linkrot, depending on which src you consult. Rarely did they mention web archives.

Gaja: We need to stop thinking of archival content as something that will be primarily consumed by human individuals. #webarchiving #iipcWAC25

021

Onward to the Advocacy & User Engagement session at #iipcWAC25 Gaja Zornada (Computer History Museum Slovenia) discusses the insufficiency of human-centric ethical guidelines in the age of AI. In the old web, content was posted w/o foresight and now it's being abused by AI.

Closing out the "Tools Under Construction" at #iipcWAC25, Dr. Natanael Arndt ( @dnb-aktuelles.bsky.social ) discusses building up a new web archive starting with the Linked Data Lifecycle. These processes can block each other but it is important to recognize that you repeat them. #webarchiving

Gil: What they learned (from British Library's point of view): they affect systems that are technical in nature, the audiences, and processes. The other teams cannot go back to their work because there were bits of technology they relied on in that chain. #iipcWAC25 #webarchiving
