A legal text is something very different from ordinary speech. Text classification, or text categorization, is the activity of labeling natural language texts with relevant categories from a predefined set. This is especially true of authoritative legal texts: those that create, modify, or terminate the rights and obligations of individuals or institutions. The goal is to classify documents into a fixed number of predefined categories, given a variable length of text bodies. So precision, recall and F1 are better measures. As such, encoding meaning and context can be difficult. Types used for Text classification.
