2017-11-22: Deploying the Memento-Damage Service

Image
Many web services such as archive.isArchive-ItInternet Archive, and UK Web Archive have provided archived web pages or mementos for us to use. Nowadays, the web archivists have shifted their focus from how to make a good archive to measuring how well the archive preserved the page. It raises a question about how to objectively measure the damage of a memento that can correctly emulate user (human) perception.

Related to this, Justin Brunelle devised a prototype for measuring the impact of missing embedded resources (the damage) on a web page. Brunelle, in his IJDL paper (and the earlier JCDL version), describes that the quality of a memento depends on the availability of its resources. The straight percentage of missing resources in a memento is not always a good indicator of how "damaged" it is. For example, one page could be missing several small icons whose absence users never even notice, and a second page could be missing a single embedded video (e.g., a Youtube pa…

2017-11-20: Dodging the Memory Hole 2017 Trip Report

At the Internet Archive, it was rainy in San Francisco, but that did not deter those of us attending Dodging the Memory Hole 2017. We engaged in discussions about a very important topic: the preservation of online news content.

Keynote: Brewster Kahle, founder and digital librarian for the Internet Archive "Let's become a library. Let's be useful to society to understand ourselves." ― @brewster_kahle#DTMH2017pic.twitter.com/rg7hMqWBdI — JDNA (@RJIJDNA) November 15, 2017Brewster Kahle is well known in digital preservation and especially web archiving circles. He founded the Internet Archive in May 1996. The WS-DL and LANL's Prototyping Team collaborate heavily with those from the Internet Archive, so hearing his talk was quite inspirational.

2017-11-16: Paper Summary for Routing Memento Requests Using Binary Classifiers

Image
While researching my dissertation topic, I re-encountered the paper, "Routing Memento Requests Using Binary Classifiers" by Bornand, Balakireva, and Van de Sompel from JCDL 2016 (arXiv:1606.09136v1). The high-level gist of this paper is that by using two corpora of URI-Rs consisting of requests to their Memento aggregator (one for training, the other for training evaluation), the authors were able to significantly mitigate wasted requests to archives that contained no mementos for a requested URI-R.For each of the 17 Web archives included in the experiment, with the exception of the Internet Archive on the assumption that a positive result would always be returned, a classifier was generated. The classifiers informed the decision of, given a URI-R, whether the respective Web archive should be queried.Optimization of this sort has been performed before. For example, AlSum et al. from TPDL 2013 (trip report, IJDL 2014, and arXiv) created profiles for 12 Web archives based on…

2017-11-06: Association for Information Science and Technology (ASIS&T) Annual Meeting 2017

Image
The crowds descended upon Arlington, Virginia for the 80th annual meeting of the Association for Information Science and Technology. I attended this meeting to learn more about ASIS&T, including its special interest groups. Also attending with me was former ODU Computer Science student and current Los Alamos National Laboratory librarian Valentina Neblitt-Jones.
