Guest lecture: Semantic Network Analysis in Social Science Research

Today I’ll be giving a guest lecture in the course on Semantic Network Analysis in the VU course on social capital and networks. I will briefly talk about big data and social science research and the central role of text analysis in “social science 2.0″. I will introduce semantic network analysis as an important form of text analysis and give two examples from my own research: (1) differences in newspaper coverage of the 2009 Gaza war between US and Chinese press, and (2) the dynamics of news diffusion in the Dutch media landscape. You can download the slides here.

Talk of Europe: Clause analysis of the Gaza War

Today I will be giving a talk at the Talk of Europe Creative Camp #3 symposium held in the Royal Library (KB). I will be presenting the use of syntactic clause analysis to analyse newspaper coverage, which often contains multiple quoted or paraphrased sources using multiple and competing frames, making it difficult to analyse with frequency based approaches.

Who killed whom in the Gaza war? Using syntactic information for relational corpus analysis
Wouter van Atteveldt & Kasper Welbers

This paper shows how syntactic information can be used to automatically extract clauses from text, consisting of a subject, predicate, and optional source. Since the output of this analysis can be seen as an enriched token list or bag of words, normal frequency based or corpus linguistic analyses can be used on this output. Taking the 2008–2009 Gaza war as an example, we show how corpus comparison, topic modelling, and semantic network analysis can be used to explore the differences between US and Chinese coverage of this war.

Connecting data for research

I’m giving a talk at the Connecting Data for Research symposium held today at the VU University.

In my presentation Dutch journalism since 1945: collecting and analysing large textual data sets with commercial owners I will be presenting some preliminary results from my study of Media Logic in Dutch newspapers since 1945, and focus on the technical and copyright-related problems with gathering, processing, and sharing large textual data sets.

Network Theory and Methods: Syntactic Clauses for Semantic Networks

I will be presenting an updated version of the “Syntactic Clauses for Social and Semantic Network Analysis” today at the ‘Network Theory and Methods’ conference organized by the Network Institute. Abstract is repeated below, you can download the full paper and the presentation slides.

Clause analysis: using syntactic information to enrich frequency-based automatic content analysis

This paper shows how syntactic information can be used to automatically
extract clauses from text, consisting of a subject, predicate, and optional
source. Since the output of this analysis can be seen as an enriched token
list or bag of words, normal frequency based or corpus linguistic analyses
can be used on this output. Taking the 2008–2009 Gaza war as an example,
we show how corpus comparison, topic modelling, and semantic network
analysis can be used to explore the differences between US and Chinese
coverage of this war.

Automated Content Analysis in Zurich: Clauses

I’m attending the Symposium on the New Frontiers of Automated Content Analysis in the Social Sciences at the University of Zurich – July 1-3, 2015.  I will be presenting a paper on using syntactic analysis for analysing clauses. Abstract is copied below, you can download the full paper and the presentation slides.

Course: Programming and Analyzing in R

Next week (22-26 June) I will give a course on programming and analyzing in R as part of the VU FSW Graduate School.

Time: Monday – Thursday, 9:00 – 13:00, with open lab until 15:30.
Location: HG 10-A41
Course Material:  github repository (subject to minor changes)
Slides: [Monday][Tuesday]

Preparation: Please bring your own laptop (contact me if you don’t have a laptop) and make sure to have the newest version of R and RStudio installed on your computer. Also please install the devtools and RTextTools packages and use devtools to install the amcat/amcat-r and kasperwelbers/corpustools packages by running the following code in RStudio:

install.packages("RTextTools")
install.packages("devtools")
library(devtools)
install_github("amcat/amcat-r")
install_github("kasperwelbers/corpus-tools")
install_github("kasperwelbers/semnet")

Note: on Windows, devtools might give a warning message, you can just ignore the message. Please contact me if you have any difficulty installing the above!

Detailed schedule:

Monday Tuesday Wednesday Thursday
Lecure + Hands-on 1 9:00 – 11:00 Getting Started Combining and Transforming Data Advanced statistics and language features Analysing text with AmCAT and R

Good books on R:

  • “Discovering Statistics using R”, by Field, Miles, and Field (Sage 2012).
  • “R for SPSS users” (Robert A. Muenchen, Springer 2009)
  • “the R book” (Michael J. Crawley, Wiley 2012).

The course is open to all Ph.D. students and colleagues (from the VU or other Universities) but a fee may apply, please contact me if you wish to attend or audit.

See you Monday!
