[Talk] The Visual Language of Comics - 8/14

By andresmh1 month ago - permalink

Tags: talks

Drawings and sequential images are an integral part of human expression dating back at least as far as cave paintings, and in contemporary society appear most prominently in comics. Just how is it that our brains understand this deeply rooted expressive system? Neil will present a provocative theory: that the structure and cognition of drawings and sequential images is similar to language.

[Talk] Tracing the Constellation of Actors in the Peer Economy - 4/16 @ 12pm

By andresmh5 months ago - permalink

Tags: talks peer economy sharing economy future of work

Tomorrow (4/16) we’ll have a Denise Cheng from MIT presenting her research on the peer economy. This is what she has to say about it: 

Americans’ normative understanding of work is imploding. Throughout most of the twentieth century Americans equated landing a job to a lifetime of smooth sailing. In recent decades, faith in gainful employment has collapsed, and other models are emerging to fill the void. The peer economy is one such model.

Whether by radio, by newspaper or by screen, you cannot miss it. Stories abound about hobbyists who sell crafts on Etsy. Dwellers use Airbnb to rent out parts of their living space to travelers. Ordinary people who use their cars as private drivers for a few hours a day. This is the peer economy. At its base are online, peer-to-peer marketplaces that enable people to monetize skills and assets they already have. Peer economy platforms equip suppliers or providers with tools that empower them to transact with strangers and, in turn, depend on these transactions for ongoing income.
I lay out the expanse of the peer economy and why it is so exciting. The flexibility of working in the peer economy brings in many people who are defined out of the traditional workplace—homecarers, the elderly, the mentally disabled, alongside the underemployed college graduate. Powering this momentum on a macro level are investors, companies, corporations, scholars, policymakers, and more. On the micro-level, however, there are very real risks, and I will detail known problems in the space, including tax remittance, regulatory skirmishes, liability, and operational costs. 
Finally, the peer economy’s expanse is also why it is so confusing. Peer economy, sharing economy, collaborative economy, crowdsourcing… liberal use of these terms have led to widespread misunderstandings. I suggest that inaccurate terminology leaves the peer economy vulnerable to criticism and peer economy users in limbo as policy begins to take shape.

[Talk] Snappers and hunters in action: Mobile crowdsourcing of hyperlocal news—Tue 1/28

By andresmh8 months ago - permalink

Tags: talks research crowdsourcing locativecrowdsourcing journalism civicmedia

UPDATE: Check out the video of this talk.
Next Tuesday, we have Heli Väätäjä from Tampere University of Technology visiting our lab to present her work on cooperative news making through mobile crowdsourcing. Below is the description of her talk:
The importance of reader’s content (images, video clips, stories) is rapidly increasing in journalism as the source of news and as news content. Our research focuses on cooperative news making with the readers. The activity is facilitated by a news organization, currently Metro in the metropolitan Helsinki area in Finland.  In 2012, the studied newsroom received 35 000 reader’s photos sent by 30 000 individuals. Majority of the 4000 stories published in 2012 were based on reader’s photos that were used as tip-offs for news in the newsroom. Since 2010 we have studied both reader initiated contributions and carried out field studies with mobile task-based cooperation in which newsroom creates the tasks. We have addressed the following themes: 1) What motivates readers to participate? 2) What influences their participation when using mobile tasks? 3) How to manage the content quality with social feedback? I will address in this talk the main findings from our studies.

UPDATE: Video recording of the talk is now available.

This coming Thursday, Ryan Acton, a computational sociology professor at UMass Amherst, is coming to give a talk on his work investigating “digital traces” online. Ryan has been studying network dynamics on websites such as epinions.com, and last.fm. For example, he’s been analyzing group formation around concerts advertised in last.fm and built an R package called scrapeR to collect data directly from R.

Talk Announcement: Microblogging During Small Scale Incidents—Tue 8/27

By andresmh1 year ago - permalink

Tags: crisisinformatics civicmedia talks

UPDATE: Video of this presentation is now available online.

Next week we have Alex Schulz from the Technical University of Darmstadt who will giving a talk about his work on using social media data along with machine learning, and semantic dictionaries (i.e., WordNet), to automatically detect small scale incidents, such as car crashes, shootings, and fires.

I saw Alex present a paper co-authored with Petar Ristoski at ICWSM during a really interesting workshop titled When the City Meets the Citizen. In that paper they analyzed Twitter data from Seattle and Memphis. One of their findings was that average citizens (labeled I and blue in the figure below) were often the first to report shootings (53% of the time), much earlier than other people that one would expect such as Emergency Management Organzations (EMO), journalists/bloggers devoted to emergencies (EMJ), general journalists/bloggers, or other types of governmental and non-governmental organizations (ORG).

Talk Announcement — Narrating with Networks: Making Sense of Event Log Data with Socio-Technical Trajectories — Fri 8/16

UPDATE: Check out the video recording of this research talk.
Brian Keegan is visiting us from Northeastern University to talk about his work studying a wide range of networks: from Wikipedia, to Twitter, to MMGO’s. One of his areas of research that I find most fascinating is the use of network science to understand how people react to breaking news events such as natural disasters, accidents, and crimes. For example, in one of his recent studies, he and his colleagues found that most of the Wikipedia articles about breaking news had a cohesive group of editors that “coalesced” in less than 24 hrs (compared to a year for other types articles!), and these articles attracted journalist-like Wikipedians who specialize in reporting breaking news events. Here is a plot where they showed this: 

Breaking news events are in red, articles about recent but non-breaking news events are in blue, and articles about historical events are in green. The x-axis is time and the y-axis is the number of articles in the giant component.

UPDATE: Check out the video recording of this talk.
Next week, we have Luis Blackaller visiting us from USC and WemoLab. He will be talking about a couple three different awesome projects he has worked on at the intersection of art and social computing: 
  • The Tiny Icon Factory is a tool and gallery for the anonymous creation of black and white low resolution icons. With over 200,000 anonymous and uncensored contributions in under two years, The Tiny Icon Factory is an ongoing exploration of creative expression.
  • PictureXS was an anonymous picture aggregator. It featured an embedded tracing tool, a self-regulated censorship system, and tags. Before it was turned off in January 2011, PictureXS had collected over 30,000 pictures, 1000 drawings and 500,000 tags, reporting activity from across the world. 
  • OpenStudio (2005 to 2008) was a pioneering experiment in creativity, collaboration & commerce. Participants created and sold artwork in an online marketplace using an embedded drawing tool and virtual currency.
