Path search method and system based on user preference, storage medium and processor

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a path search method, system, storage medium and processor based on user preference. Background technique [0002] With the advent of the 21st century, the information industry is developing rapidly. Information sharing through the network has developed an unprecedented prosperous era since web2.0. The network has gathered data resources contributed by a large number of users, forming the current situation of information explosion. In the current network environment, every user is the creator of information, but also the disseminator and user of information. The sharp increase in information on the Internet has enhanced the diversification and diversification of information, making it easier for users to obtain all kinds of online resources they need. At the same time, the pace of informatization has also driven traditional offline operations to be realized o...

Problems solved by technology

[0004] However, there are almost no services that provide route search services that appear in the public eye, and route search services based on user preferences are even more difficult to see in the market.

Although there are many studies in this field, most researchers either only provide an efficient path search algorithm, or only provide a personalized recommendation algorithm, and there is no technology that combines path search and personalized recommendation.
