Multiplicative Fusion
A multi-factor scoring fusion strategy in information retrieval that combines multiple relevance factors multiplicatively, preventing entries with low base relevance from being excessively promoted even when assigned high saliency weights, thereby improving recall while maintaining retrieval precision.
Timeline (last 90 days)
The salience boost is blended into the embedding retrieval score multiplicatively rather than additively, to ensure relevance still dominates and to prevent irrelevant content from being forcibly surfaced.
Additive fusion can cause entries to be forcibly pushed to the top of results and generate false positives even when they are completely irrelevant to the query at trigger activation time, whereas multiplicative fusion requires a non-zero base relevance score before amplification can occur.
