Description

technical field [0001] The present application relates to a map query method and device, in particular to a technology for map query based on user requirements contained in query sentences. Background technique [0002] Various electronic map service systems currently on the market can not only provide users with searching for various points of interest through the Internet, but also provide users with navigation functions such as route and road condition query. However, these map service systems require the user to input clear location information in order to provide relevant feedback results. When the location information entered by the user is not clear or the input information is too general, the feedback result is often empty. Sometimes even if the user has many Changing the search content entered for a second time can not get the result that meets the user's needs. For example, when the user enters "Dating with his girlfriend at Shangdi Hualian at 7 o'clock tonight" in...
