Dr. Collins at the Research Excellence Awards Speakers Series

On March 23 Dr. Christopher Collins presented a talk Understanding Culture and Society Through Visual Text Analytics at the UOIT Research Excellence Awards Speakers Series, as a recipient of the 2016 award.  The talk is available to watch online.

Our ability to communicate through language is often considered the hallmark of humanity. Through language data, we leave traces of our individual personalities and our culture online. In this talk Dr. Collins discussed how the vialab investigates language data to provide insights into culture and society. From the secret language of passwords, to the public broadcast of social media, the vialab team has created interactive visualizations for exploring and revealing patterns in language data. How do people feel about my product? What are the main themes in the news today? These are examples of the questions people ask about large scale text data. Through harnessing the power of language data, we have detected rumors on Twitter, discovered car parts contributing to accidents, and analyzed the written history of the court system. In addition to an overview of our research projects, this talk presented some of the technologies and techniques we use to achieve these results and discussed the open challenges and opportunities for the future of linguistic data as a lens on culture and society.

The introduction of Dr. Collins as read by Vice President Research, Innovation, and International Dr. Michael Owen, appears below:

Dr. Christopher Collins is an assistant professor in the Faculty of Science and holds a Tier 2 Canada Research Chair in Linguistic Information Visualization. His cutting edge research program combines information visualization and human-computer interaction with natural language processing to address the challenges of linguistic information management and the problems with information overload. Using a trans-disciplinary approach crossing computer graphics, design, and linguistics, Dr. Collins provides new analytic tools to data-intensive fields as diverse as legal studies and bioinformatics. His designs integrate gesture and touch interaction to enable analytic processes that are both intuitive and powerful.

Dr. Collins’ visualization designs are informed by deep investigation into real-world linguistic data problems. These new techniques are widely cited and highly impactful, as demonstrated by his work having more than one thousand citations and the pick up of his research by the scientific and popular media. An example of the breadth of Dr. Collins’ contributions can be seen in his recent investigation of the “secret language of passwords”. His team published two papers which deconstruct millions of real passwords to reveal the semantic patterns encoded within them. A password guessing algorithm based on their findings surpassed the best available cracking techniques on many measures. The research has garnered media attention including a major article by Pulitzer-prize winning journalist Ian Urbina at the New York Times Magazine.

Dr. Collins’ creativity in research and scholarship is exemplified through his innovative application of a variety of methodologies, including grounding ethnographic studies of how people work with language data as well as qualitative and quantitative evaluations of resulting visualization designs. In his research, he relies on information visualization, natural language processing, and the exciting interactive power of natural user interfaces and large multi-touch displays. Dr. Collins is the only researcher in Canada with expertise in all three of these areas.

Dr. Collins’ research has attracted significant support from national granting agencies and industry partners. In his five years as a professor at UOIT, he has received $1.4 million in direct research funding as the sole investigator and additional support through his participation on joint projects and National Centres of Excellence. Dr. Collins’ research promises to contribute innovations that will enhance our ability to leverage the tsunami of big data to drive positive change in business, policy-making, and education. His current NSERC Discovery Grant introduces mixed-initiative visual text analytics, whereby computer systems provide just-in-time and contextually appropriate guidance to analysts.  This proposed direction was considered so highly that his application was awarded a rare “Discovery Accelerator Supplement”, an additional grant recognizing outstanding research potential.  Collins leads the Visualization for Information Analysis lab in the Faculty of Science, where he supervises undergraduate and graduate students focusing on information visualization, with special attention on text and document analysis. The VIA lab maintains collaborations with academic colleagues at UOIT and beyond, as well as industrial collaborations. Positions in the VIA lab are highly sought after and he receives dozens of requests from prospective students each year. It is clear that our students are as grateful to have Dr. Collins at UOIT as we are.

Description

We often think of data as quantitative variables or as discrete pieces of information that bear little or no cultural significance in their assumed “raw” state. With the increasing digitalization of every aspect of today’s life, they have become crucial not only in understanding trends, behaviours, phenomena etc.., but also in initiating reflections on their very nature. A lot has been written about the politics and ethics involved in collecting data, and the ways in which data are endlessly and invisibly seized thanks to algorithms and technological devices. Conversely, little attention has been given to the creative processes employed, the artistry that goes into making them meaningful and, often, beautiful, or the conceptual reflections that data collection as an activity evokes. During this ArtSci Salon, we hope to instigate this latter aspect by presenting diverse, though ultimately converging perspectives and practices of artists Graham Wakefield and Haru Ji, and computer scientist Christopher Collins.

Bios

Artificial Nature is the artistic partnership of Haru Ji and Graham Wakefield (http://artificialnature.mat.ucsb.edu/home.html) exploring the subject of life and complex systems in art through artificial natures: a form of computational generative art creating artificial life ecosystems as immersive environments. Rather than representing nature as it appears, we aim to create an environment in the manner that nature works. It is an interdisciplinary art form linking the generative open-endedness of both biology and computation within aesthetic experience. Since 2008, A.N. have had over thirty-five exhibits across nine countries,including festivals such as SIGGRAPH (Yokohama), Microwave (Hong Kong), Digital Art Festival (Taipei), conferences such as ISEA (Singapore), and EvoWorkshops (Tubingen), and venues including La Gaite Lyrique (Paris), CAFA (Beijing) and City Hall (Seoul). It was awarded honorable mention in the international VIDA competition, 2014.

Christopher Collins (http://vialab.science.uoit.ca/) is the Canada Research Chair in Linguistic Information Visualization and an Assistant Professor of Computer Science at the University of Ontario Institute of Technology (UOIT).  His research focus is interdisciplinary, combining information visualization and human-computer interaction with natural language processing to address the challenges of information management and the problems of information overload.  His work has been published in many venues including IEEE Transactions on Visualization and Computer Graphics, and has been featured in popular media such as the Toronto Star and the New York Times Magazine.  Dr. Collins received his PhD in Computer Science from the University of Toronto.

Vialab to receive $300,000 for new research

On June 22nd, the Honourable Ed Holder announced that UOIT researchers and trainees will receive $1.9 million through the Natural Sciences and Engineering Research Council of Canada (NSERC)’s Discovery Grants program. Of this funding, $300,000 will be given to Vialab’s Dr. Christopher Collins in order to develop new techniques, purchase new equipment, and conduct training to allow for the development of new ways to present large volumes of text-based data easily to users.

During his speech at the announcement, Dr. Collins had this to say: “My laboratory focuses on new ways of visualizing big data, extracting meaningful information that makes those data relevant to groups like businesses and policy makers. The NSERC Discovery Grant and Discovery Accelerator Supplement enables us to explore how visualizing big-data can discover hidden patterns, unknown correlations, market trends, customer preferences and other useful information that can help Canadians make informed decisions. The grants also assist the next generation of researchers, like the students in my lab, to become future leaders and innovators.”

This new funding will allow 10 students to work at Vialab, provide the ability to give them data science training, and increase the budget to enable the purchase of new equipment for the lab.

After the announcement, a tour of the lab was given to the Minister, MP Pat Perkins, and the President of NSERC, Dr. Mario Pinto, during which members of Vialab gave demos to showcase their research projects. The reception they received was favorable, and the demos being shown impressed many of the guests.

Seminar: Adaptive Technologies to Support Language Learning by Carrie Demmans Epp

Carrie Demmans Epp from the TAGLab at University of Toronto will give a seminar entitled “Adaptive Technologies to Support Language Learning” as part of the UOIT Computer Science seminar series.  Ms. Epp shares research interests with members of the vialab, including technology for language learning, as exemplified in our projects TandemTable and our collaboration with Quillsoft on the iWordQ series of applications.  The details of the seminar are below.  The talk will be webcast live and archived.

When: Wednesday, Jan 21, 2015 @ 3:30pm

Where: UA 4170

Who: Carrie Demmans Epp, University of Toronto

Title: Adaptive Technologies to Support Language Learning

Abstract: Technology use is deeply rooted within language learning. From the early use of language labs and more recent use of multi-media, we have seen the wide use of technology by language learners. This talk will present two adaptive language-learning tools and discuss their deployment in various cultural and educational contexts. The first tool is a computer-based pronunciation tutor for Russian (ProTutor) and the second is a mobile-based English communication support and study tool (VocabNomad). Both systems employed representations of the user’s knowledge (learner models) to drive their adaptive content recommendation and personalized feedback.

These adaptive features helped to motivate learners, enabled their self-regulation, and supported learning activities and outcomes. Their use by high school and university students also demonstrated the need for them to be accompanied by appropriate pedagogical practices when used as support tools in formal learning environments.

Biography: Carrie Demmans Epp is a doctoral candidate in human-computer interaction at the University of Toronto. She completed her BSc (Computer Science and Russian) and MSc (Artificial Intelligence in Education) at the University of Saskatchewan. She has recently finished visiting researcher terms with the Open Learner Models at Birmingham group (UK) and the Graduate School of Language, Communication, and Culture at Kwansei Gakuin University (Japan). She was a recipient of the 2013 Weston Fellowship and is a current Walter C. Sumner Memorial Fellow.

Carrie’s work focuses on the development and use of adaptive educational technology and the mechanisms that are used to provide feedback to learners within these environments. Her work bridges populations and has included university students, underprivileged children, students in special education settings, and language learners.

UOIT Password Research featured in New York Times and other media

The password security research of vialab researchers Christopher Collins and Rafael Veras, and collaborator Julie Thorpe from the Faculty of Business and Information technology has been featured by Pulitzer-prize winning journalist Ian Urbina in a feature article in the New York Times Magazine.  In his article, “The Secret Life of Passwords“, Urbina investigates the stories behind the passwords we use.  Through the concept of keepsake passwords, the article investigates the evocative stories hidden in passwords. Our research relates to this work in that we have been investigating the numeric and linguistic patterns in passwords, in terms of how these patterns affect security as well as how these patterns reveal the culture and language.

Our research has also been featured in additional media, including:

We have also been featured on UOIT Homepage, including and article entitled “Heartbleed update: UOIT researchers analyze why consumers use weak passwords
