Discourse Analysis of Public Debates Using Corpus Linguistic Methodologies

The aim of this study is to develop a computational method of discourse analysis based on corpus semantics. The objective is to achieve an accurate understanding of the debate content and structure through hypotheses generation. As for verifying the hypotheses, the topic extraction and semantic similarity evaluation from the public debate minute corpus is examined by using a multimethod which includes TFIDF, T-VSM, and MDS. The main issue of public debate and the inconsistency level between participants’ utterance could be described by using the method. The methodology presented in this study is applied to a case example. Finally, the applicability of the proposed methodology to practical debates is discussed.

Disaster Anxiety Measurement and Corpus-Based Content Analysis of Crisis Communication

The aim of this study is to develop a methodology for evaluating public anxiety arising from disaster events and to clarify the nature of crisis communication between the government and citizens. Preparing for catastrophes that may happen in the future is an important issue in risk management. In the Great East Japan Earthquake, Twitter was used widely as a means of sharing information about the disaster. This paper proposes a methodology for measuring anxiety by determining semantic orientations of risk assessments and clarifying the contents and structures of crisis communication systems by referencing the corpus of government announcements and Twitter during the week after the Great East Japan Earthquake. Objectivity of this paper has been ensured by applying natural language processing and text mining techniques based on corpus linguistics.

An Ontology-Based Computational Framework for Analyzing Public Opinion Framing in News Media

The aim of this study is to develop a computational framework for analyzing the framing of news coverage for controversial public issues by comparing the coverage from ideologically distant news media sources. Because news media sources play a key role in the formation of public opinion, their coverage also plays a major role in the dynamics of the public debates. It can be hypothesized that the public interactions of political players may be treated differently in the media based on the editorial perspective of the media sources in question and the positions that the political players occupy in the political arena. However, the question arises, how can these differences be measured? Using corpus extraction techniques, SPARQL queries, and ontology engineering, this study compares the positions that key political players occupy in discourse spaces that are modeled by two ideologically distant news media sources based on the same controversial public issue.

Regional learning and trust formation

The contributions in this volume extend our understanding about the different ways distance impacts the knowledge conversion process. Knowledge itself is a raw input into the innovation process which can then transform it into an economically useful output such as prototypes, patents, licences and new companies. New knowledge is often tacit and thus tends to be highly localized, as indeed is the conversion process. Consequently, as the book demonstrates, space or distance matter significantly in the transformation of raw knowledge into beneficial knowledge.

Facet Decomposition and Discouse Analysis: Visualization of Conflict Structure

Public debate has become an important process in the planning of public projects where stakeholders including citizens, experts, enterprises, and administrators meet face-to-face to discuss the desirability of a public project in its early planning stages. The roles of public debate are: to clarify the pros and cons of a project, that is, evaluate available information and proposed approaches; to promote mutual understanding of the stakeholders’ different perspectives; and to find resolutions that are mutually beneficial for all stakeholders.
