Abstract: 【Purpose/significance】An argumentation model is constructed to characterize the argumentation process of open innovation community interaction information, which provides a theoretical reference for the in-depth development and utilization of open innova⁃ tion community interaction information【. Method/process】Based on the classical argumentation model combined with the characteris⁃ tics of open innovation community interaction information to construct a three-level argumentation model containing argumentation el⁃ ements, argumentation relations and argumentation configurations, and based on the argumentation model to design an annotation scheme to capture the semantic roles of the interaction information of the open innovation community; the semantic annotation is ap⁃ plied to 11133 comment messages of 160 interactive information units in Xiaomi community to explore the argumentation features of interactive information at three levels of argumentation elements, argumentation relations and argumentation constructions.【Result/ conclusion】The annotation results show that the interactive information argumentation model contains 6 argumentation elements, namely fact, testimony, value, policy, reference, and rhetoric statements, and different argumentation elements present different fea⁃ tures in terms of number and position; the distribution and pattern of argumentation elements under the 2 argumentation relations of support and attack present different features, and different combinations of argumentation elements form a variety of argumentation configurations, and there are some differences in the features of argumentation elements, argumentation relations, and argumentation configurations among different dialog targets´ interaction information【. Innovation/limitation】The argumentation structure and features of interaction information in open innovation communities is revealed. However, only the Xiaomi community is considered in this re⁃ search, and subsequent studies can further compare whether there are differences between different open innovation communities.
