Hi everyone, my (Weiwen's) paper can be found here: https://www.dropbox.com/s/vf3l5aaaxtoif98/EmotionalCues.pdf?dl=0
Hi all,
In addition to Weiwen, Zhicong Lu will also deliver a practice talk on his
paper that he is going to present at CSCW. The paper is one of his works on
live streaming. Please join us and give him feedback on his presentation.
Below are the details of his presentation.
*Title*: StreamWiki: Enabling Viewers of Knowledge Sharing Live Streams to
Collaboratively Generate Archival Documentation for Effective In-Stream and
Post Hoc Learning
*Abstract*:
Knowledge-sharing live streams are distinct from traditional educational
videos, at least because of the large concurrently-viewing audience and the
real-time discussions between viewers and the streamer. Though this creates
unique opportunities for interactive learning, it also brings a challenge
for creating a useful archive for post hoc learning. This paper presents
the results of interviews with knowledge sharing streamers, their
moderators, and viewers to understand current experiences and needs for
sharing and learning knowledge through live streaming. Based on those
findings, we built StreamWiki, a tool which leverages the viewers during
live streams to produce useful archives of the interactive learning
experience. On StreamWiki, moderators initiate tasks that viewers complete
by conducting microtasks, such as writing a summary, commenting, and voting
for informative comments. As a result, a summary document is built in real
time. Through the tests of our prototype with streamers and viewers, we
found that StreamWiki could help in understanding the content and the
context of the stream, during the stream and for post hoc learning.

Hi All,
We have our HCI group meeting tomorrow at 12:30 PM at DGP Seminar
room.
Weiwen Leung is going to give a practice talk on his paper that he
going to
present in CSCW next month. The paper is about the impact of NFL
games to
the Wikipedia editors that identify themselves as fans of NFL
teams
(abstract is below). Please drop by and help Weiwen to prepare for
the
talk, while at the same time give feedback on this awesome work.
Lunch will
be provided during the meeting.
Thanks,

Exploiting evidence that sporting results affect fans’ mood, we
analyze
whether National Football League game outcomes can affect the
contributions
of Wikipedia editors who identify as fans of a specific team. We find
that
the day after a team loses, their fans decrease their contributions
towards
football-related pages (relative to after a win). Relative decreases
are
bigger if losses are unexpected, or if losing margins are big. In
contrast,
unexpected wins do not cause more contributions relative to wins that
were
not unexpected. Neither do big wins result in more contributions
relative
to small wins. Additionally, contributions to non-football-related
pages
are not affected by NFL game results. Our findings add to the
literatures
on (i) the determinants of individual contributions to peer
production
communities, (ii) how community dynamics affect user contributions,
(iii)
the importance of emotions, (iv) the effect of offline events on
online
behavior, and (v) the applicability of behavioral economics concepts
to the
HCI literature.
