Sometimes users make searches on expedia web pages by first visiting search engines such as google or bing, typing a query (e.g. &quot;cheap hotels new york&quot;), and then clicking on the expedia (sponsored or not) link. srch_query_affinity_score is a (log) probability of clicking on a hotel given a search query. These probabilities were estimated from historical click-stream data. The actual search queries are not part of the released dataset. The reason that a given hotel has different scores is because if was presented in the context of different search queries. </p>\n<p>&nbsp;</p>\n<p>Cheers,</p>\n<p>Adam</p>\n<p>&nbsp;</p>",
