(Previous semester highlights posts: Spring 2017 , Spring 2016 , Spring 2015 , Spring/Fall 2013 , Fall 2012 , Fall 2011 ) Here are a few projects that I'd like to highlight from Fall 2017. (All class projects are listed in my InfoVis Gallery .)  All of the projects were implemented using the D3.js library. World Leader Interactions on Social Media (Twitter)  Created by Grant Atkins This project (available at http://www.cs.odu.edu/~gatkins/world-leader-vis/app/ ) provides an interactive dashboard to visualize ways Twitter list data can be used and represented. This visualization uses the World Leaders list on Twitter , with the addition of a few world leaders not on the list, to derive information and visualize shared information among these users. The goal of this visualization is to show shared term usage among world leaders, see which times tweets are more likely to be sent out, the sentiment of the users, and the decay of data allocated in a static decreasing tim

At iPres 2018 , I will be presenting "The Many Shapes of Archive-It", a paper that focuses on some structural features inherent in Archive-It collections. The paper is now available as a preprint on arXiv . As part of the data gathering for " The Many Shapes of Archive-It ", and also as part of the development the Off-Topic Memento Toolkit , I had to write code that extracts metadata and seeds from public Archive-It collections. This capability will be useful to several aspects of our storytelling and summarization work , so I used the knowledge gained from those projects and produced a standalone Python library named Archive-It Utilities (AIU) . This library is currently in alpha status, but is already being used with upcoming projects. The metadata available from an Archive-It collection Archive-It curators can use the predefined metadata fields of Dublin core. They can also supply their own custom metadata fields.

Inspired by AlNoamany's work from " Detecting off-topic pages within TimeMaps in Web archives " I am pleased to announce an alpha release of the Off-Topic Memento Toolkit (OTMT). The results of testing with this software will be presented at iPres 2018 and those results are now available as a preprint . Web archive collections are created with a specific purpose in mind. A curator will supply seeds for the collection and create multiple versions of these seeds in order to study the evolution of a web page over time. This is valuable for following the changes in an organization or the events in a news story. Unfortunately, depending on the curator's intent, sometimes these seeds go off-topic. Because web archive crawling software has no way to know that a page is off-topic, these mementos are added to the collection. Below I list a few examples of off-topic pages within Archive-It collections. This memento from the Human Rights collection at Archive-It create

This may sound familiar , but yet again I'm way behind in posting about my previous offerings of CS 725/825 Information Visualization. (Previous semester highlights posts: Spring 2016 , Spring 2015 , Spring/Fall 2013 , Fall 2012 , Fall 2011 ) Here are a few projects that I'd like to highlight from Spring 2017. (All class projects are listed in my InfoVis Gallery .  This semester has its own page because there were 19(!) projects.)  All of the projects were implemented using the D3.js library. Because the Spring 2017 semester began with President Donald Trump's Travel Ban ( EO 13769 ) and we have a large international graduate student population, students were understandably interested in US immigration and refugee data.  The first two projects here focus on that.  In addition, one project looked at sentiment about the US Presidential candidates on social media on Election Day. The last two projects that I'll highlight are focused on the lighter topic of sports,

Fort Worth Museum of Science & History 9/11 Tribute The theme of the workshop on Knowledge Discovery from Digital Libraries (KDDL) was to uncover hidden relationships between data with techniques from artificial intelligence, mathematics, statistics, and algorithms. The workshop organizers, which included ODU Computer Science alumna, Dr. Hui Shi , Dr. Wu He , and Dr. Guandong Xu identified the following objectives that we were to explore: Existing and novel techniques to extract and present knowledge from digital libraries; Advanced ways to organize and maintain digital libraries to facilitate knowledge discovery; Knowledge discovery applications in business; and New challenges and technologies brought to the area of knowledge discovery and digital libraries.

On June 3, 2018, PhD students arrived in Fort Worth, Texas to attend the Joint Conference on Digital Libraries Doctoral Consortium . This is a pre-conference event associated with the ACM and IEEE-CS Joint Conference on Digital Libraries . This event gives PhD students a forum in which to discuss their dissertation work with others in the field. The Doctoral Consortium was well attended, not only by the presenting PhD students, their advisors/supervisors, and organizers, but also by those who were genuinely interested in emerging work. As usual, I live-tweeted the event to capture salient points. It was a very enjoyable experience for all. Thanks very much to the chairs: J. Stephen Downie , University of Illinois at Urbana-Champaign , USA Oksana Zavalina , University of North Texas , USA Daniel Gelaw Alemneh , University of North Texas , USA Sampath Jayarathna , Old Dominion University , USA In this post I will cover the work of all accepted students, three of whom are
