Code Review
This pull request introduces a new test suite for rule-based relation extraction, covering scenarios with no entities, single entities, and affiliation relations. However, the test case for affiliation is expected to fail because the underlying implementation in muninn/extraction/rules.py currently lacks support for the 'affiliation' predicate and the associated text patterns. It is recommended to either update the core extraction logic or modify the test to use supported relation types like 'prefers' or 'depends_on'.
| def test_extract_relations_rule_based_affiliation(): | ||
| # Test affiliation relation extraction according to the snippet logic. | ||
| # The snippet says: | ||
| # "If an organization and person appear close to each other, assume affiliation" | ||
| org = Entity(name="Acme Corp", entity_type="organization") | ||
| person = Entity(name="John Doe", entity_type="person") | ||
|
|
||
| # Text where they appear close | ||
| text = "John Doe works at Acme Corp." | ||
| result = extract_relations_rule_based(text, [org, person]) | ||
|
|
||
| # As per snippet logic, an affiliation relation is assumed between them. | ||
| # We assert that a relation is returned and its subject and object match the entities, | ||
| # and the predicate indicates some affiliation/connection. | ||
| assert len(result) == 1 | ||
| # Check that both entities are involved in the relation | ||
| assert result[0].subject in ["John Doe", "Acme Corp"] | ||
| assert result[0].object in ["John Doe", "Acme Corp"] | ||
| assert result[0].subject != result[0].object | ||
| # According to the evaluator feedback: | ||
| # "testing 'affiliation' between a 'person' and an 'organization'" | ||
| assert result[0].predicate == "affiliation" |

The test case test_extract_relations_rule_based_affiliation asserts functionality that is not currently implemented in muninn/extraction/rules.py. The extract_relations_rule_based function only processes PREFERENCE_PATTERNS and DEPENDENCY_PATTERNS, neither of which include the "affiliation" predicate or patterns matching "works at". Consequently, this test will fail as result will be an empty list. To align with the current implementation, consider testing a supported relation type like prefers or depends_on, or update the core extraction logic in muninn/extraction/rules.py to support affiliation.

This assertion introduces a consistently failing test because extract_relations_rule_based currently only emits relations for preference/dependency regex matches, and the input sentence "John Doe works at Acme Corp." does not match any implemented pattern. In this commit, the new test therefore fails in the default suite (len(result) is 0), which blocks CI until the test is rewritten to match existing behavior or the extractor is extended to support affiliation.
