Abstract

In this paper the authors present a system that combines the cognitive and socio-cultural paradigms in the field of discourse analysis in order to analyze both texts written by only one author for example narrations and those written collaboratively chat conversations, blogs, wikis, forums. The novelty of their approach is that the majority of the existing applications are oriented on analyzing only one of these two types, an adaptation being necessary for the analysis of the other type. Another advantage of the presented system is that since it is centered on a dialogistic polyphonic model considering topics as inter-animated voices, it could show the difference between coarse-and fine-grained coherence in discourse, therefore allowing the analysis of a text from two different viewpoints: a its intrinsic structure and cohesion and b how well this text fits in a stream of texts whether it is or not cohesive with the texts before and after it. The dialogistic polyphonic model was used as a starting point for a method for analyzing collaboration and social construction of knowledge in groups and communities using textual interactions, and for several implemented systems for providing computerized support to the analysis method through visualizations and feedback generation.
