New blog post: Re-launching COPTR!

2026-01-22: Paper Summary: "Towards a better QA process: Automatic detection of quality problems in archived websites using visual comparisons" The Web Science and Digital Libraries Research Group at Old Dominion University.

Travis Reid @treid803.bsky.social @webscidl.bsky.social summarizes Brenda Reyes Ayala's @brendareyesayala.bsky.social 2025 paper:

"Towards a better QA process: Automatic detection of quality problems in archived websites using visual comparisons"

I find that it's the opposite with coding. The execution (act of programming) is fun but the planning is often not-so. Some folks also probably dread writing the syllabus. Regarding that, you and I are in the same camp.

My site monitor just reported that the ACM Hypertext 2026 (@acmht.bsky.social) conference web site is live! I enjoyed attending HT'25 in Chicago & hope to submit a paper (due Mar. 27).

I've no affiliation as an organizer but someone you know might also want to target this venue.

Thrilled to see @ktmac.bsky.social and my paper on robots.txt and infrastructural consent published here!!

Screenshot of a paper entry: Fictional Failures and Real-World Lessons: Ethical Speculation Through Design Fiction on Emotional Support Conversational AI Authors: Faye Kollig, Jessica Pater, Fayika Farhat Nova, Casey Fiesler (There are tabs with "abstract" and "summary" and "summary" is selected.)

The ACM Digital Library, where a LOT of computing-related research is published (I'd say at least 75% of my own publications), is now not only providing (without consent of the authors and without opt-in by readers) AI-generated summaries of papers, but they appear as the *default* over abstracts.

TIL about github.com/midwork-find..., a DuckDB ext. to query web archive CDX APIs directly from SQL. i.e., query Wayback Machine & Common Crawl CDX APIs like they were database tables!

Problems With Archiving and Replaying Web Advertisements - Information Matters Advertisements are an integral part of our cultural heritage, and this extends to online web advertisements. Unlike print ads, web ads are dynamic and interactive, which makes them difficult to archiv...

We also published a blog post on Information Matters, which provides a summary of our process for creating a dataset of 279 archived web ads and the problems we identified while archiving and replaying these ads. (2/9)

2025-10-26: Exploring the Different Generations of Twitter/X's Tweet UI The Web Science and Digital Libraries Research Group at Old Dominion University.

To study Twitter is to study archived Twitter. And if you're replaying archived pages, you need to be familiar with the different generations of UIs.

Tarannum Zaki of @webscidl.bsky.social explores and classifies the different UIs.

Next year's Hypertext 2026 will be in London at School of Advanced Study at University of London and the British Library. #HT2026

The theme will be Hypertext as Method.

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
