ALGORITHM

Input: Two simple directed acyclic graphs (DAGs)

1. Counterpart mappinga. Find all paths, accounting for temporal ordering

2. Counterpart-collection via rulesa. Exact-matchb. Predicate-matchc. Ordered-entity-match

3. Mapping-selectiona. Iconicity preferenceb. Default heuristic: Maximize # of pair matches

4. Modify-targeta. Exact-match: no changeb. Predicate-match: change one entityc. Ordered-entity-match: change predicate

Output: One "blend" DAG

NUGGETS AND COAL

• Need to conduct evaluation

• Produces zero or one blends

• Causality is a tricky problem

• Performance• Optimal blends• Context??

• Simple knowledge representation

• Satisfying temporality constraints

• Creative blends!• Human-like blends

by using iconicity
