How Yahoo enhances search retargeting using Amazon Bedrock
Yahoo replaced Word2Vec with Amazon Bedrock LLMs for DSP search keyword expansion
Yahoo's DSP team swapped a Word2Vec + locality-sensitive hashing pipeline for Amazon Bedrock LLMs to generate semantically richer keyword expansions for Search Retargeting campaigns. The old approach suffered from outdated vocabulary, syntactic-only similarity, and occasional zero-expansion failures. This is a solid applied-AI case study but a vendor co-marketing post rather than a novel research or strategic signal.
