Enthymeme, which is arguments with missing premises or conclusions, is common in natural language text. Enthymeme reconstruction, the art of reformulating arguments with missing propositions, has not been effective in argument classification and consequently, rhetorical Algorithms have yielded poor result. They cannot discover features, text orientation, intent and sentiments in enthymematic arguments. This has led to poor performance of enthymematic Natural language toolkits. Hence, generating new context of enthymematic data reconstruction will provide better and useable insight. The aim of this research is to build a manual annotation framework for enthymemes to enable appropriate tagging and effective classification in argumentation. Manual Annotation technique is used in this experiment to manually separate statements that contain an aspect (enthymemes) from ArguAna corpus of hotel reviews from TripAdvisor.com to know the opinion from the statements. A total of 1201 reviews gave 5575 opinions which were then annotated with defined conclusions. The linear Support Vector Machine (SVM) and fastText classifier were used to train and test data while Valence Aware Dictionary for sEntiment Reasoning (VADER) was used to assign scores for each word based on sentiments. MATLAB and Python programming language were used for model implementation. The supervised learning approach showed the best performance results on the test set with a macro averaged F1-scores of 0.72 and 0.94 for explicit and implicit stances respectively. The identified implicit stances are explicit premises of either complete arguments or enthymemes. (If they are premises of complete arguments, there are other, additional premises.) The identified explicit stances can represent common knowledge information for the implicit premises, thus becoming explicit premises to fill in the gap present in the respective enthymemes. The experimental framework shows that manual annotation of enthymeme data can provide better and useable insight in machine based annotation.
