FORMALIZATION: CONCEPTUAL BLENDING Image source: according-to 3
EXAMPLE BLEND 4
EXAMPLE OUTPUT 5
ALGORITHM Input: Two simple directed acyclic graphs (DAGs) 1.Counterpart mapping a.Find all paths, accounting for temporal ordering 2.Counterpart-collection via rules a.Exact-match b.Predicate-match c.Ordered-entity-match 3.Mapping-selection a.Iconicity preference b.Default heuristic: Maximize # of pair matches 4.Modify-target a.Exact-match: no change b.Predicate-match: change one entity c.Ordered-entity-match: change predicate Output: One "blend" DAG 6
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 7
