Learn a straightforward method to count overlapping interactions without double-counting errors.", "---", "### Introduction", "In linguistics, computer science, and formal logic, adjacency pairs—such as question-answer, hello-biere, or question-answer—represent structured paired behaviors that mutually depend on one another. Tracking or counting occurrences of these pairs accurately is essential for natural language processing, dialogue systems, and conversation analysis. However, when adjacency patterns overlap or overlap with other categorizations, counting becomes error-prone due to double-counting.", "This is where the principle of inclusion-exclusion becomes a powerful tool.", "---", "### What is Inclusion-Exclusion?", "The principle of inclusion-exclusion (PIE) provides a formula to calculate the size of a union of multiple sets without overcounting elements that belong to more than one set.
