Abstract
A method and device for extracting a keyword on the basis of a geographic location. The method achieves various keyword extraction techniques. The method comprises: acquiring geographic location information of a target user, and determining a user type of the target user according to the geographic location information (S102), wherein the user type comprises a first type of user located at a specified geographic location and / or a second type of user located at a non-specified geographic location; acquiring a first behavior feature word of the first user type on the basis of the specified geographic location, and / or acquiring a second behavior feature word of the second user type on the basis of the non-specified geographic location (S104); and determining a keyword related to the specified geographic location according to the first behavior feature word and / or the second behavior feature word (S106).
Description
technical field [0001] This specification relates to the technical field of information mining, in particular to a method and device for extracting keywords based on geographic location. Background technique [0002] Keyword extraction has important applications in fields such as information retrieval and natural languageprocessing. Keyword extraction, as a way to quickly obtain document topics, has brought a lot of convenience to users' life and work. For example, it can quickly understand the user's intention according to the user's search keywords, so as to recommend some useful documents to the user according to the user's intention. information. However, at present, in many aspects, keyword extraction mostly adopts the method of mining keywords from document content, which is relatively simple, so there is a lot of room for improvement. Contents of the invention [0003] The purpose of one or more embodiments of this specification is to provide a method and device ...
