Speaker: Marijn ten Thij, Vrije Universiteit Amsterdam
Talk Title: Beyond tracking: modelling human behavior through social media
Abstract: In this talk, I present my ongoing work in modeling human behavior
using data from online platforms. I will discuss three of my projects
that focus on two online platforms Wikipedia and Twitter. First, I
will illustrate how I model the effect of promoting content on the
page view activity on Wikipedia by using the page view logs provided
by WikiMedia. I will then discuss the random graph model I designed
based on data from Twitter, which may be used to mimic the progression
of a trend through the network of Twitter. Finally, I will talk about
my current project, where we aim to capture business value from a
social feed for the Horticulture Industry.
Biography: Marijn ten Thij is a PhD student in Mathematics at Vrije Universiteit
Amsterdam, who graduated in Applied Mathematics at the Stochastic
Operations Research group at the University of Twente. His research
interest lies in the fields of Complex Science, Network Science and
Big Data. In 2014, Marijn was a member of the Dutch National
ThinkTank, where he worked on the question Can Big Data be used to
make the Netherlands more mobile, more social, and more healthy?
Marijn lives in Amsterdam and enjoys playing American pool billiards
in his spare time.

NL Seminar - ConversAtion level Syntax SImilarity Metric CASSIM)

Speaker: Reihane Boghrati , (USC)
Talk Title: ConversAtion level Syntax SImilarity Metric CASSIM
Series: Natural Language Seminar
Abstract: Abstract: The syntax and semantics of human language can illuminate many individual psychological differences and important dimensions of social interaction. Thus, analysis of language provides important insights into the underlying psychological properties of individuals and groups. Accordingly, psychological and psycholinguistic research has begun incorporating sophisticated representations of semantic content to better understand the connection between word choice and psychological processes. While the majority of language analysis work in psychology has focused on semantics, psychological information is encoded not just in what people say, but how they say it. We introduce ConversAtion level Syntax SImilarity Metric (CASSIM), a novel method for calculating conversation-level syntax similarity. CASSIM estimates the syntax similarity between conversations by automatically generating syntactical representations of the sentences in conversations, estimating the structural differences between them, and calculating an optimized estimate of the conversation-level syntax similarity. Also, we conduct a series of analyses with CASSIM to investigate syntax accommodation in social media discourse. Further, building off of CASSIM, we propose ConversAtion level Syntax SImilarity Metric-Group Representations CASSIM GR. This extension builds generalized representations of syntactic structures of documents, thus allowing researchers to distinguish between people and groups based on syntactic differences.
Biography: Reihane is a forth year Ph.D student at USC, working with Morteza Dehghani in Computational Social Science Laboratory. She is interested in introducing new methods and computational models to psychology, and more broadly to social sciences. Her work spans the boundary between natural language processing and psychology, as does her intellectual curiosity.
