In argument mining, determining claims, premises, reasons, and evidence involves a multi-step process that typically includes natural language processing (NLP) techniques and machine learning models. First, text segmentation and tokenization are used to divide text into manageable units, such as sentences or phrases. These segments are then categorized to identify possible claims, which are statements or conclusions that the author attempts to prove. Then the premises and reasons that support the claims are identified by analyzing the logical and rhetorical structure of the text. This often involves dependency analysis to understand the syntactic relationships between words. Finally, evidence, consisting of data, examples, or authoritative quotes that support the premises, is extracted by looking for specific indicators of factual support or empirical data within the text. Machine learning models, trained on annotated data sets, can automate and improve this process by recognizing patterns and characteristics associated with each argumentative component.
