+_DESCRIPTION = """
+Returns the rate at which the input predicted strings exactly match their references, ignoring any strings input as part of the regexes_to_ignore list.
+"""
+
+_KWARGS_DESCRIPTION = """
+Args:
+    predictions: List of predicted texts.
+    references: List of reference texts.
+    regexes_to_ignore: List, defaults to None. Regex expressions of characters to
+        ignore when calculating the exact matches. Note: these regexes are removed
+        from the input data before the changes based on the options below (e.g. ignore_case,
+        ignore_punctuation, ignore_numbers) are applied.
+    ignore_case: Boolean, defaults to False. If true, turns everything
+        to lowercase so that capitalization differences are ignored.
+    ignore_punctuation: Boolean, defaults to False. If true, removes all punctuation before
+        comparing predictions and references.
+    ignore_numbers: Boolean, defaults to False. If true, removes all punctuation before
+        comparing predictions and references.
+Returns:
+    exact_match: Dictionary containing exact_match rate. Possible values are between 0.0 and 1.0, inclusive.
+Examples:
+    >>> exact_match = evaluate.load("exact_match")
+    >>> refs = ["the cat", "theater", "YELLING", "agent007"]
+    >>> preds = ["cat?", "theater", "yelling", "agent"]
+    >>> results = exact_match.compute(references=refs, predictions=preds)

+    0.25
