Spaceflight resource searching method and system considering user preferences

Abstract

The invention provides a spaceflight resource searching method and system considering user preference, which collects, analyzes and sorts retrieval sample data of a user, and comprises the following steps of: based on the interest and preference characteristics of the user, accurately positioning the content of an interested part of the user by utilizing search, extracting and resorting the data information interested by the user, obtaining user retrieval sample data; carrying out the step of spatial information user modeling, wherein the step comprises that an interval mathematical mode is adopted for representation of a user model, core metadata is described through a range, and the core metadata comprises a spatial range and a wave spectrum range; carrying out the step of spaceflight resource active search based on the user model, which comprises the following steps: after reading the user model, establishing a user interest ideal solution, reading to-be-searched spatial data, calculating the correlation degree between the to-be-searched spatial data and the user interest, calculating the utility degree of each piece of to-be-searched spatial data, and returning the spatial data with the highest utility degree to the user; collecting feedback information from retrieval sample data of the user, and updating and adjusting the user model in time.

Description

technical field [0001] The invention relates to a novel space resource network search method and system, belonging to the technical field of computer networks. Background technique [0002] In the context of today's big data era, more and more people communicate and communicate through the Internet, and the Internet has become an important way for human beings to obtain information resources. However, the rapid development of network technology has also brought about many problems, one of which is information overload. Faced with a large amount of information provided by the network, people have been unable to accurately obtain useful resources to meet their own needs, and the information utilization rate has gradually declined with the increase in the amount of data. The emergence of search systems provides a very effective method to solve this major problem. Different from traditional search engines, it can not only meet the general search requests of users, but also mee...
