Summary:
Probabilistic topic models provide a suite of tools for analyzing large document collections. Topic modeling algorithms discover the latent themes that underlie the documents and identify how each document exhibits those themes. Topic modeling can be used to help explore, summarize, and form predictions about documents. Topic modeling ideas have been adapted to many domains, including images, music, networks, genomics, and neuroscience. Traditional topic modeling algorithms analyze a document collection and estimate its latent thematic structure. However, many collections contain an additional type of data: how people use the documents. For example, readers click on articles in a newspaper website, scientists place articles in their personal libraries, and lawmakers vote on a collection of bills. Behavior data is essential both for making predictions about users (such as for a recommendation system) and for understanding how a collection and its users are organized. In this talk, I will review the basics of topic modeling and describe our recent research on collaborative topic models, models that simultaneously analyze a collection of texts and its corresponding user behavior. We studied collaborative topic models on 80,000 scientists' libraries from Mendeley and 100,000 users' click data from the arXiv. Collaborative topic models enable interpretable recommendation systems, capturing scientists' preferences and pointing them to articles of interest. Further, these models can organize the articles according to the discovered patterns of readership. For example, we can identify articles that are important within a field and articles that transcend disciplinary boundaries. More broadly, topic modeling is a case study in the large field of applied probabilistic modeling. Finally, I will survey some recent advances in this field. I will show how modern probabilistic modeling gives data scientists a rich language for expressing statistical assumptions and scalable algorithms for uncovering hidden patterns in massive data.

Summary:
Thanks to Mauri Williamson, the Pioneer Village has become one of the most popular and beloved activities of the Indiana State Fair. The Village celebrates Indiana’s agricultural heritage through displaying antique tractors and farm implements, as well as by hosting old-time craft and farm-life demonstrations. The roots of the Village date to 1961 when Mauri, then the Purdue Agricultural Alumni Association secretary, brought a collection of farming artifacts from the university to create an educational display at the Indiana State Fair. In 1968, the Village began to grow when the Fair built a barn dedicated to housing its unique collection. From fiddling and quilting to threshing and storytelling, today the Pioneer Village features dozens of musicians, artisans, and demonstrators who share their talents with fairgoers. More than just the founder of the Pioneer Village, for over 54 years Mauri Williamson has worked to make the Village a memorable experience for countless Hoosiers. The Indiana State Fair Master Award was established to recognize long-time fair participants, who share their knowledge and talents at the Fair. Indiana University's Traditional Arts Indiana and Indiana State Fair are Honored to name Mauri Williamson the 2015 Indiana State Fair Master.

Angotti, Joseph
Summary:
Joseph Angotti’s career took him from student news director of Indiana University’s WFIU newscast to senior vice president for news at NBC and the chairmanship of the broadcast program at Northwestern University. Born a bakery manager’s son in Gary, Indiana, Angotti received his undergraduate degree in education from IU in 1961. He had taken a few journalism courses as an undergraduate, and he cultivated his interest in journalism further by earning his master’s degree in telecommunications at IU. In 1962, Angotti landed his first job in television at WHAS-TV in Louisville. From that point on, his rise in the industry was rapid. In 1966, he moved to WMAQ-TV, Chicago’s NBC-owned affiliate, where he was both producer and on-air reporter for its Gary bureau. In 1968, he became an NBC network producer, covering the Democratic National Convention in Chicago, where he was tear-gassed during the street protests. In 1972, Angotti was promoted to a producer slot in New York City with NBC Nightly News. He soon became executive producer of the weekend newscast with anchor Tom Brokaw. Angotti was awarded a national Emmy in 1975 for co-producing a series about world hunger and was chief political producer for the network’s election coverage in 1976. Working with John Chancellor, anchor of the weeknight NBC Nightly News, Angotti was the newscast’s executive producer from 1977 to 1980. Angotti later was named the senior vice president for news at NBC, overseeing coverage of presidential conventions and debates, space shuttle launches and landings, and the fall of the Berlin Wall. In June 1989, Angotti was in Bloomington for IU professor Richard Yoakam’s retirement party, but had to rush off to return to New York to oversee NBC’s coverage of the massacre in Tiananmen Square. He was an early protégé of Yoakam, who had developed and launched IU’s broadcast journalism program. In 1992, Angotti left NBC and formed his own company, which produced coverage of events such as the 25th Anniversary Gala of the Metropolitan Opera. He also wrote, filmed and edited a series of programs in Eastern Europe, From Marx to Markets, which were filmed, edited and broadcast in Eastern Europe. Next, Angotti took his knowledge to the classroom. From 1993 to1998, he was the chair of communication studies for the University of Miami’s School of Communication and was founding director of its Center for Advancement of Modern Media. In 1999, Angotti was named chair of the broadcast program at Northwestern’s Medill School of Journalism and taught there for the following six years. He also founded the Northwestern News Network, which produced weekly newscasts for Chicago area TV stations. He continues to teach journalism at Monmouth College in Illinois. In 2006, he was inducted into the Indiana Journalism Hall of Fame.

40. Tom Olin - ADA Legacy Bus Tour (18:24)

Summary:
“The shot that was heard around the world for people with disabilities,” is how one of Tom Olin’s photographic images has been described. As part of the ADA at 25 Legacy Tour, the Monroe County History Center in Bloomington, Indiana hosted an exhibit of Tom Olin’s work. On June 19, 2015, Tom gave a public talk in association with the exhibition. He was also present as the driver of the touring ADA Legacy bus. It made Indiana stops in Bloomington, Monticello, and Indianapolis during a national tour celebrating the 25th anniversary of the Americans with Disabilities Act. Tom has become widely known for the powerful advocacy of his photography focusing on the disability rights movement. In this videotaped talk, he discusses how he became involved in documenting the struggle for the rights of people with disabilities, and provides information about photographs in the exhibit. Some of the iconic photographs he discusses include images of the event now referred to as the Capitol Crawl. Depicting the landmark protest where people got out of their wheelchairs to ascend the steps of the U.S. Capitol building, it became “the shot that was heard around the world.” The action on March 12, 1990 was initiated by the activist organization ADAPT (Americans Disabled for Accessible Public Transit ). Tom identifies disability leaders at the protest and points out that his eight-year-old niece, Jennifer Keelan, is among those shown crawling up the steps. Tom explains that even though the “Crawl” took place just a few months before the ADA was passed into law, there were numerous attempts being made to weaken its provisions. “In Congress, you had the Senate and the House conferring on the bill that was to be. And they had all these different ways of how they thought the bill should look like.” Tom also describes photographs in the exhibit documenting other ADAPT actions in Memphis and at the federal building in Atlanta. It’s up to us, he says, to make sure the work of grassroots activists continues. “I see things happening. You know, I'm really impressed with a lot of young people.”
