A few days ago, I read an interesting blog post by  Peter Bengtsson . Peter is sampling web pages  and computing basic statistic on the number of domains ( RFC 3986 Host ) required to completely render the page.  Not surprisingly, the mean is quite high: 33.  Also not surprisingly, he has found pages that depend on more than 100 different domains. This started me thinking about how this has changed over time. Over the course of my research I have acquired a corpus of composite mementos (archived web pages and all their embedded images, CSS, etc.) dating from 1996 to 2013.  So, I did a little number crunching. What I suspected and confirmed is that the number of domains has increased over time and that the rate of increase has also increased. This is reflected in the median domains data show in Figure 1. Note that the median shown (3) is a fraction of Peter's (25). I believe there are two major reasons for this. First, our current process for recompo...

When an archived web page is viewed using the Wayback Machine, the archival datetime is easy to determine from the URI and the Wayback Machine's display.  The archival datetime of embedded resources (images, CSS, etc.) is another story.  And what stories their archival datetimes can tell.  These stories are the topic of my recent research and Hypertext 2015 publication.  This post introduces composite mementos, the evaluation of their temporal (in-)coherence, provides an overview of my research results.   What is a composite memento?   A Memento is an archived copy of web resource ( RFC 7089 )  The datetime when the copy was archived is called its Memento-Datetime .  A composite memento is a root resource such as an HTML web page and all of the embedded resources (images, CSS, etc.) required for a complete presentation.  Composite mementos can be thought of as a tree structure.  The root resource embeds other resources, which...

The 2017 Joint Conference on Digital Libraries (JCDL) took place at the University of Toronto , Canada. From June 19-23, we (WS-DL) attended workshops, tutorials, panels, and a doctoral consortium. The theme of this year's conference was #TOscale, #TOanalyze, and #TOdiscover. The conference provided researchers from disciplines such as Digital Library research and information science, with the opportunity to communicate the findings of their respective research areas. Day 1 (June 19) The first day (pre-conference) of the conference kicked off with a Doctoral Consortium and a Tutorial - Introduction to Digital Libraries. These events took place in parallel with a Workshop - 6th International Workshop on Mining Scientific Publications (WOSP 2017). The final event of the day was a tutorial titled, "Scholarly Data Mining: Making Sense of the Scientific Literature" Day 2 (June 20) . #JCDL2017 kicks off with opening remarks by @ianmilligan1 pic.twitter.com/...

The 2024  IEEE Visualization and Visual Analytics Conference (VIS) , initially scheduled as a hybrid event from October 13 to 18 at the Hilton Tampa Downtown in Tampa, Florida, was transitioned to an entirely virtual format due to Hurricane Milton's projected trajectory and the potential for significant impacts on the Tampa area. I participated virtually, attending workshops, full paper presentations, and engaging panel discussions. IEEE VIS  is a premier forum for showcasing visualization and visual analytics theory, methodologies, and application advancements. This year, the conference had an overall acceptance rate of 22.26%. Our paper, " Towards Enhancing Low Vision Usability of Data Charts on Smartphones ," was accepted as a full paper. I had the privilege of presenting it on October 17, 2024, from 13:45 to 15:00 EST. 👀 Keep an eye out for our daily VIS 2024 round ups and other posts this week to follow the conference on social media. We can’t wait to see you virtu...
