A Socio-Semantic Network Analysis of Discourse Using the Network Lifetime and the Moving Stanza Window Method

Abstract

This study proposes a new temporal Socio-Semantic Network Analysis (SSNA) of discourse by using the network lifetime and the moving stanza window method to analyze idea improvement in learning as knowledge-creation. The procedure of our proposed method has four steps. The first step entails making a discourse analysis unit. One discourse analysis unit is composed of discourses depending on the set numbers at a size of the moving stanza window method. The second step is calculating the total value of degree centrality for each discourse analysis unit with periods of the network lifetime by using SSNA. The third step involves calculating the difference value between discourse analysis units to define the candidates for the pivotal points. The last step is tracing the discourse back from the candidates for the pivotal points to identify segments for in-depth dialogical discourse analysis. To evaluate the proposed method, we analyzed discourse data in collaborative learning using different methods with and without the network lifetime and moving stanza window. As a result, new pivotal points were detected by implementing both the network lifetime and the moving stanza window method. An in-depth dialogical discourse analysis of a new pivotal discourse segment confirmed the appropriateness of the detection. Based on the results, it is concluded that our proposed method is better in detecting pivotal points of learning as knowledge-creation compared to the previous approach.
