@WalmartLabs has acquired Adchemy, the slightly mysterious Foster City, Calif., adtech company that specializes in "semantic search," or trying to develop meaningful, implied search results that go beyond the mere keywords punched into Google. Semantic search could be a huge business, but only if it turns out that software is better at predicting what humans want than the keywords they type in.
