Gap Detection: Mitigating Homogenization through Demand and Defensibility

We introduce Gap Detection, a framework that searches for relevant but unoccupied directions in a shared text embedding space.

Key points

  • Language models often produce semantically similar answers to open-ended questions, even when many plausible alternatives exist.
  • Its objective, GapScore, combines query relevance (Demand) with dissimilarity to the nearest existing item (Defensibility).
  • We also instantiate the framework for generative engine optimization over four product markets and for iterative synthetic-data augmentation.
  • These results support explicit gap search as a practical mechanism for diversifying content, with task validity checked separately from geometric novelty.
