Matching method for spatial information services based on context awareness and user preferences

Abstract

The invention discloses a matching method for spatial information services based on context awareness and user preferences. The method includes: considering context-aware user preferences on the basis of functional and non-functional matching of user service requests and candidate spatial information services, calculating matching degree of the user service requests and each candidate spatial information service in smart space, and recommending the candidate spatial information service to a user according to the matching degree. The user may have fixed or repeated preferences, but the preferences may not be relevant at any time. The matching method for spatial information services based on the context awareness and the user preferences is capable of simplifying the user preferences and eliminating irrelevant user preferences. In the mean time, by calculating the matching degree from the functional and non-functional matching, accuracy in spatial information service matching is enhanced, and the spatial information service which mostly meets actual needs of the user is provided.

Description

technical field [0001] The invention belongs to the technical field of spatial information services, and more specifically relates to a spatial information service matching method based on context perception and user preference. Background technique [0002] With the continuous innovation of IT technology, the concept of traditional information service recommendation system has undergone tremendous changes, and ubiquitous computing will occupy an important position in the future information service recommendation system. Since Marc Weiser first proposed the concept of ubiquitous computing, a large number of researchers have devoted themselves to the research of context awareness. [0003] In the user-centered information service recommendation system, the most basic element is context awareness, where context refers to all information that can be used to describe the user's situation. The interaction between the user and the information service recommendation system is usua...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a spatial information service matching method based on context awareness and user preference, so as to solve the problem that the existing spatial information service matching method does not take into account the user's mobility and thus As a result, the variability and distortion of user needs make it impossible to discover the real needs of users, making the accuracy of service matching low.
