delphin.mrs.compare¶

delphin.mrs.compare.compare_bags(testbag, goldbag, count_only=True)[source]¶

Compare two bags of Xmrs objects, returning a triple of (unique in test, shared, unique in gold).

Parameters:	testbag – An iterable of Xmrs objects to test. goldbag – An iterable of Xmrs objects to compare against. count_only – If True, the returned triple will only have the counts of each; if False, a list of Xmrs objects will be returned for each (using the ones from testbag for the shared set)
Returns:	A triple of (unique in test, shared, unique in gold), where each of the three items is an integer count if the count_only parameter is True, or a list of Xmrs objects otherwise.

delphin.mrs.compare.isomorphic(q, g, check_varprops=True)[source]¶

Return True if Xmrs objects q and g are isomorphic.

Isomorphicity compares the predicates of an Xmrs, the variable properties of their predications (if check_varprops=True), constant arguments, and the argument structure between predications. Node IDs and Lnk values are ignored.

Parameters:	q – the left Xmrs to compare g – the right Xmrs to compare check_varprops – if `True`, make sure variable properties are equal for mapped predications
