The invention discloses a path search method and system based on a user preference, a storage medium and a processor. The method comprises the steps that a search condition is input for path screening; an offline POI dataset is called in the path screening process, and a set initial search radius is used to perform search and judge whether candidate paths matched with search information exist; allPOI data is stored, and a candidate path set is generated; the search radius is changed, and search is repeated till the candidate paths matched with the search information exist; the offline POI dataset and a user preference dataset are called to score and order all the candidate paths in the candidate path set; an ordering result formed by all the candidate paths after ordering is displayed fora user to make a choice; and the path selected by the user is recorded, and the user preference dataset is synchronously updated. Through the path search method and system, the storage medium and theprocessor, the problem that in the prior art, path search and personalized recommendation are not combined in the path search process is solved, and search efficiency is improved.
