Care.com is considered the go-to site for caregivers in the US, but it just faced a serious shakeup. The company has confirmed that it took down 46,594 daycare center listings (45 percent of the listings in its database) after a Wall Street Journal report found that hundreds of listings weren't actually state licensed as claimed.

The company already warned that it didn't verify listings, but that only appeared at the bottom of pages until after the article. The same report also noted that Care.com offered only limited vetting of caregivers.
Airbnb's marketplace contains millions of diverse listings which potential guests explore through search results generated from a sophisticated Machine Learning model that uses more than hundred signals to decide how to rank a particular listing on the search page. Once a guest views a home they can continue their search by either returning to the results or by browsing the Similar Listing Carousel, where listing recommendations related to the current listing are shown. In this blog post we describe a Listing Embedding technique we developed and deployed at Airbnb for the purpose of improving Similar Listing Recommendations and Real-Time Personalization in Search Ranking. The embeddings are vector representations of Airbnb homes learned from search sessions that allow us to measure similarities between listings. They effectively encode many listing features, such as location, price, listing type, architecture and listing style, all using only 32 float numbers.
