Discourse Visualization Strategies for a Comprehensive Medial Analysis of Cultural Science Communities

Year 2004

Knowledge creation in the cultural sciences is very often of discursive nature. The individuals participating in these discussions can be regarded as a part of a community. In our collaborative research center on ''Media and Cultural Communication'' we are analyzing the impact of "Networked multimedia Information Systems in Cultural Science Communities" on organization and creation of knowledge. In this aspect, we are researching on discourse visualization strategies for a comprehensive medial analysis of cultural science communities. Subject of the present investigation are discourses in about 40 discussion forums with an amount of more than 25.000 emails from more than 2500 individuals collected so far. Research aspects focus on the detection of emergent phenomena by the concatenation of discussion maps originated in the area of data mining and classifying meta data for the documents analyzed. Interesting phenomena in cultural science discourses are the sudden emergence and disappearance of terms (burstiness) in a particular forum as well as their spanning among various forums. The correlation of these burstiness phenomena and individuals is also an indicator for roles and hierarchies of individuals within debates. Another phenomenon is the drifting of terms within a community or among them what often can be ascribed to members being active in several communities and "infecting" them by spreading new terms. Fraunhofer FIT's web based tool SWAP-it has been equipped with a community specific terminology on the basis of web services allowing a comprehensive study on the previously described phenomena also by self-supervision.
