Area sampling frame - An area sampling frame is an organized representation of geographical sampling units from which a survey sample can be selected.
Area under the PR curve - Area under the PR curve summarizes a model's precision-recall tradeoff as its decision threshold changes.
Argument mining - Argument mining is the automatic identification of claims, reasons and argumentative relationships in natural-language material.
Argumentation framework - An argumentation framework is a formal representation of arguments and relationships between them, used to analyze which arguments can be accepted together.
Argumentation mining - Argumentation mining is the computational analysis of how people present claims, give reasons, and connect those reasons through support or opposition in text.
