Introductory Workshop to Network Analysis of Texts

Announcement



Date: 2nd to 5th February 2004
Place: Lisbon, Portugal in ISEG (Institute of Economics and Business Administration- Technical University of Lisbon)
Organization: SOCIUS (Research Centre on Economic Sociology and the Sociology of Organisations)
Professor: Vladimir Batagelj (University of Ljubliana, Slovenia) – http://vlado.fmf.uni-lj.si/

Objective: Familiarise the participants with the main concepts, methods and applications of network analysis of text and to teach the basic tools to conduct such an analysis.

Description: Different ways to derive networks from textual data and an overview of applications of network analysis to the analysis of text will be presented. Examples of analyses of different text networks will be given as illustrations: bibliographic networks (for instance authors collaboration networks and citation networks), dictionary networks (Foldoc, Odlis, EAT, Wordnet, etc.) text analysis networks, which through natural language processing and network analysis techniques produces abstract representations of texts (ex: analysis of news concerning terrorist attacks, KEDS). The course will also have a strong focus on visualisation of these networks.

Program: Monday to Thursday – theory: 9.30 - 13h ; practice: 14.30-17h


Content of the course:

Day 1.  Introduction to graphs, networks and Pajek.
               Obtaining networks from textual data.
Day 2.  Structure of networks (statistical characteristics,
               components, cores, islands, ...)
Day 3.  Important elements in networks (indices and weights).
               Acyclic networks.
Day 4. Clustering and blockmodeling. Patterns searching.

In the afternoon the concepts from the morning lectures will be applied in the analysis of real-life networks obtained from textual data. The software utilised will be PAJEK, a program for large network analysis and visualisation (freely available at http://vlado.fmf.uni-lj.si/pub/networks/pajek )
