Cohesion describes the logical and grammatical connections within a text, ensuring ideas flow seamlessly and parts are interlinked via linguistic devices like pronouns and conjunctions. The Cohesion Metric quantifies these aspects, assessing the relatedness of elements in texts or the unity within software classes, where a high score indicates a focused, single-function class or a text where ideas are closely interconnected. This metric is essential for evaluating textual clarity and the structural quality of software, aiming to enhance understandability and maintainability by ensuring components contribute meaningfully to the overall objective.
