In this talk Professor Schumaker, who teaches at Central Connecticut State University, will try to answer the question: “Can the sentiment contained in tweets serve as a meaningful proxy to predict match outcomes and if so, can the magnitude of these outcomes be similarly predicted based on the degree of sentiment?”
This talk should be an excellent place to learn about some of the key areas the initiative is trying to explore–big data and text analysis. The predictive power of sentiment analysis has been a consistent element of Schumaker’s work which he has applied to the stock market as well as sports.
There will be some refreshments available and we’ve found that a Friday afternoon talk can be a nice way to end the week. What’s more, this talk give you just enough time to work things out before the Saturday morning kickoffs and certainly before Chelsea goes to the Arsenal that Sunday.
Can the sentiment contained in tweets serve as meaningful proxy to predict match outcomes and if so, can the magnitude of these outcomes be similarly predicted based on the degree of sentiment? To answer these questions we constructed the CentralSport system to gather Tweets from the English Premier League and analyze their sentiment content for use in predicting match outcomes. From our analysis, we found that the models incorporating positive tweets were easier to profit from (All Positive model netted a $3,375.18 excess return). Looking deeper into the models we found point spread prediction was possible. Clubs with 1,000 or more negative tweets than their rival would typically lose by 1 goal (observed 65.2% of the time). Clubs with 2,000 to 10,000 more positive tweets would win by 1 goal (56.25%) and 10,000+ positive tweets would win by 2+ goals (100%). These results demonstrate the power of hidden information contained within tweet sentiment and has implications on wagering systems.

Between 1300 and 1550, church court across Europe frequently excommunicated delinquent debtors for breach of faith. This did not reflect the preoccupations of prelates or ecclesiastical judges, but widespread, popular demand for legal-religious remedies in matters of day-to-day, relatively minor credit.
By examining the practice of excommunication for debt in light of recent theories of network and organizations, we can glimpse how pre-Reformation believers understood the Church–and the market.

Ellen Thomas, Research Professor of Earth and Environmental Studies, is featured on the News @ Wesleyan blog.
“Up until recently, Thomas taught students about microfossils through microscope studies and by showing text book illustrations and images embedded in slide presentations. But with support from the National Science Foundation, Thomas and her peers were able to use cutting-edge technology to create high-resolution images and 3-D models of more than 40 microfossils in the phyla Foraminifera and Ostracoda.”

Wesleyan will host The New York Times’ Amanda Cox, who will give a talk on “Data Visualization at the New York Times.” Cox has been an essential part of one of the most interesting developments in contemporary journalism, the growth of data journalism, which in the innovative contexts of papers such as the Times and the Guardian have brought the analytic edge of social science back into journalism, most often by uniting it with powerful images. As Wesleyan prepares to launch its own data journalism course next year Cox, who teaches such a course at NYU, couldn’t be a more timely speaker.
Please announce it to your classes and come along yourself.

Dr Silke Schwandt from Bielefeld University will lead an informal discussion of getting involved in collaborative digital humanities projects and integrating new text analysis methods in research. Schwandt will talk about her experience as a humanist involved in a large multi-year digital humanities project to make richly accessible the largest single body of medieval texts, and she worked to teach the computer how to recognise and ‘understand’ medieval Latin, in which most words have a very large number of forms. Her own research work used this database to analyse the political concept of Virtue in the central middle ages. She’ll start off by talking about her experiences.
Lunch will be served; if you hope to make it, or need more information, contact Gary Shaw.

Part of the goal of the Digital and Computational Knowledge Initiative is to get faculty to enrich their knowledge of techniques and concepts so we can then share it with a wider audience. Over the last couple of years, we have been keen to push network analysis to the forefront. This fall a group of faculty and students–undergraduate and graduate–have met weekly as part of a proseminar on networks (QAC 239) and we’d like to show and tell a bit about network theory and analysis, especially now that our first course introducing students to networking—is heavily subscribed and ready to launch this January. (QAC 241)
So please come join us for a Manhattans & Martinis seasonal fête, featuring good drinks, satisfying snacks, and easygoing discussion. We’ll meet on Monday, December 15th at 4PM in Allbritton 311.
You’ll be able to hear your colleagues give glimpses of the power and grace of network analysis. We’ll learn from David Beveridge, Psyche Loui, Francis Starr, and Pavel Oleinikov about what network analysis is, what it’s good for, and how you and your students can learn a little more about it.
By December 15th, the term will be over, the grading marinading, and the bartender will be tending her bar, from 4PM.
Talk: Monday, November 17th at 3pm
GIS, remote sensing, GPS, and the Internet have transformed maps
from static documents into dynamic windows on a rapidly changing world. Combining
maps with multimedia content and user experiences comprises a powerful new
storytelling medium. Allen Carroll, former chief cartographer at National Geographic
and current program manager of storytelling at Esri, will describe his recent adventures
developing map-based narratives.
Allen Carroll is Program Manager for Storytelling at Esri. He leads Esri’s Story Maps
team, which develops open-source web apps that enable thousands of people to tell
their own place-based stories combining interactive maps and multimedia content. The
team also develops its own story maps in order to prototype new user experiences and
to demonstrate best practices for map-enabled storytelling. The team’s website is at
storymaps.arcgis.com. In addition, Allen helps guide strategy for organizing Esri’s online
content and for serving its global user communities.
Allen came to Esri after 27 years at the National Geographic Society. As chief
cartographer at NGS, he was deeply involved in the creation of the Society’s renowned
reference and wall maps, globes, and atlases. He led the creation of the Seventh and
Eighth editions of the World Atlas, incorporating satellite imagery and innovative
thematic maps into the editions and integrating them for the first time with interactive
Web resources. He spearheaded the publication of many new maps and Web resources,
ranging from decorative wall maps and supplement maps for National Geographic
magazine to special projects featuring biodiversity, conservation, and indigenous
cultures. He is a former member of the National Geospatial Advisory Committee.
Lev Manovich is the author of Software Takes Command (Bloomsbury Academic, 2013), Soft Cinema: Navigating the Database (The MIT Press, 2005), and The Language of New Media (The MIT Press, 2001) which was described as “the most suggestive and broad ranging media history since Marshall McLuhan.” Manovich is a Professor at The Graduate Center, CUNY, and a Director of the Software Studies Initiative that works on the analysis and visualization of big cultural data. In 2013 he appeared on the List of 25 People Shaping the Future of Design.
His website is manovich.net.
