1. A method, performed by a computing system, for generating trending action statistics that match a query, comprising: receiving a query identifying one or more of: a search action or a search action target; selecting a set of posts relevant to the query, the set of posts comprising one or more action posts that contain at least one sentence that specifies a post action and a post action target; for one or more selected action posts of the one or more action posts: dividing the selected action post into one or more sentences; creating, for at least one action sentence of the one or more sentences, a dependency structure correlating an action of the action sentence with an action target of the action sentence; determining, based on the dependency structure, that the selected action post matches the query by: determining that the search action specified in the query matches the action identified in the dependency structure; or determining that the search action target specified in the query matches the action target identified in the dependency structure; in response to determining that the selected action post matches the query, updating a count of matching actions or a count of matching action targets corresponding to the action or action target identified in the dependency structure; generating a response to the query by computing statistics based on the count of matching actions or the count of matching action targets; and providing the response to the query.
