Embodiment Construction

[0046] The implementation of the present invention will be described in detail below in conjunction with the examples and drawings, so as to fully understand and implement the implementation process of how the present invention uses technical means to solve technical problems and achieve technical effects.

[0047] In the establishment of a personalized feature model, it is necessary to further set personalized interest weights for information points belonging to the same type. For example: for "gourmet food", its subordinate attributes are taste, price and sanitation. For individuals, the weight factors are determined according to their own subjective judgments. In order to accurately describe the personality model, the AHP is used to calculate the feature matrix and feature vector for description. figure 1 It is a flow chart of an embodiment of the feature model-based personalized information recommendation method of the present invention. refer to figure 1 As shown, the f...

Abstract

The invention discloses a personalized information recommendation method based on a feature model. The method comprises the following steps: optimization construction of a user personality characteristic model: constructing a user personality characteristic pairing comparison matrix based on an analytic hierarchy process; comparing the constructed comparison matrix of the user personality characteristics in pairs with only a first attribute and other attributes, and optimizing other values by adopting an automatic reasoning calculation method; establishing a feature information base of the target object; obtaining positioning information of a user terminal, calculating a target distance, and retrieving an established feature information base of a target object based on a constructed user personality feature model to complete retrieval and recommendation of position-related personality information. According to the technical scheme, the personalized demand characteristics of the user and the distance between the user and the target information point are integrated, personalized recommendation information can be provided for the user timely and accurately, and personalized information requirements of different types of users are met.

Description

technical field [0001] The invention belongs to the field of data analysis multi-target decision-making / information recommendation, and in particular relates to a feature model-based personalized information recommendation method. Background technique [0002] Usually in the information recommendation, for the information push of real-time location, it is generally used to pre-establish the information point information database related to the surrounding location, and then through the real-time location acquisition, the content information and the location are associated and searched to complete the method of location-related information recommendation. Afterwards, with the rapid development of mobile Internet and LBS applications, demands and applications gradually tended to diversify along with the progress of technology. From the simple association of information content and geographical location in the past, it gradually began to develop in the direction of precision and...
