2020-07-31: Sami Uddin (Computer Science Masters Student)

Image
Hello everyone! My name is Sami Uddin (you can call me Rayan!) and I am a member of the Web Science and Digital Libraries (WS-DL) research group at Old Dominion University (ODU). I have joined ODU in Spring 2020 as a Masters student in the Department of Computer Science. Also, I am currently working with Dr. Vikas G Ashok and exploring the field of web accessibility for people with visual impairment.
My first semester here has elapsed pretty quickly. I took CS 595-Intro to Machine Learning where I learned about various machine learning algorithms and techniques on both supervised and unsupervised learning problems. In addition to that as the course project, Dr. Suninvolved me in one of his projects which gave me the taste of working in the field of bioinformatics. Besides, I had a chance to take CS 665-Computer Architecture, taught by Dr. Olariu which enriched my knowledge in hardware and their functionalities, pipelining, parallelism and scheduling, and memory hierarchy. Furthermore, …

2020-07-29: Working With Archives Unleashed Cloud

Image
Archives Unleashed Cloud is one of the tools from the Archives Unleashed Project that I have been learning about recently. (The Archives Unleashed Project was recently awarded a $1M grant from the Andrew W. Mellon Foundation to continue their work and further integrate Archives Unleashed and Archive-It.) As Figure 1 illustrates, Archives Unleashed Cloud takes an Archive-It collection, performs domain-level and textual analysis, and produces derivatives that can be directly visualized or imported into other tools. The crawl report for an Archive-It collection is shown at the top of Figure 1. This collection was created by my advisor Dr. Michele Weigle and the name of the collection is "South Louisiana Flood - 2016". This collection was created to archive an unexpected event which was a flood that occurred in August 2016 in southern Louisiana. I used Archives Unleashed Cloud to analyze this Archive-It collection so that I could get derivatives for this collection like hyperlin…

2020-07-21: Excited to join WS-DL group at ODU

Image
As a new member of WS-DL group, I like to share a bit of my story before joining ODU CS. I have received my BS and MS in Computer Engineering in Iran. I have graduated with a PhD degree in Computer Science from Texas A&M University in 2018.  I was a member of the Center for the Study of the Digital Libraries (CSDL) group. I have worked with Dr. Frank Shipman. My research interests are in Computer Human Information Interaction, Data Science, Machine Learning and Data Mining, Information Retrieval, Digital Libraries, Web Archive, Digital Data Preservation, and Social Computing.

I have years of experience in teaching computer science courses. While I was working on my PhD research remotely, I kept my connection with academia and have taught several different courses at Computer Science department at Virginia Tech for two years (2017-2019). My family and I moved to Norfolk last year (Fall 2019) and I started as a full-time faculty at Physics, Computer Science and Engineering Department…

2020-07-15: Twitter Was Already Difficult To Archive, Now It's Worse!

Image
On May 29, 2020, Twitter attached a disclaimer to one of U.S. President Donald Trump’s tweets on the Minneapolis protests. This disclaimer labeled the tweet as violating Twitter Rules about glorifying violence. A similar case happened on May 26, 2020, when Twitter added a fact-check label to two of the President’s tweets on mail-in voting. On replaying these tweets through web archives, most of the archived pages, or mementos, failed to include the disclaimer and the label. This tweet thread shows how different archiving platforms failed to replay Twitter's disclaimer. Figure 1 shows how the disclaimer is missing in the archived copy in the Internet Archive's Wayback Machine. The other visible difference shown in the above image is the variation in Twitter UI. The memento of the Minneapolis protests tweet has the old Twitter interface, while the live tweet itself has the new Twitter interface. This difference in interface is also the cause of the missing disclaimer. The discla…
