Embodiment 1

[0077] figure 1 It is a schematic flowchart of a portrait modeling method based on multidimensional data in an embodiment of the present invention. Such as figure 1 Shown, a kind of portrait modeling method based on multidimensional data, described method comprises:

[0078] Step 110: Obtain user history data;

[0079] Specifically, to obtain the user's historical consumption data, for example, through a crawler program, crawl data about restaurants, including name, per capita consumption, total number of comments, cuisine, location; user review records, including user id, comment Store name, rating, comment text content.

[0080] Step 120: cleaning the historical data, and dividing the historical data into behavior data and text data;

[0081] Specifically, the obtained historical data is cleaned, including: table data association, related data quantification, and removal of duplicate and invalid data. The historical data is divided into behavior data and text data.

Abstract

The invention provides a portrait modeling method and device based on multi-dimensional data. The method comprises the steps of obtaining the user historical data; cleaning the historical data, and dividing the historical data into the behavior data and the text data; carrying out weighted mean shift algorithm clustering on the behavior data to obtain a first result; performing the word segmentation processing and feature weighting processing on the text data; training a classifier, classifying the text data obtained after the word segmentation processing and feature weighting processing through the classifier, and obtaining a second result; generating a label value according to the first result and the second result; and updating or outputting the portrait data according to the tag value,so that the technical problem that in the prior art, the portrait modeling is affected when dimensions of the historical data is more is solved, and the technical effects that the corresponding quantitative labels are formed by preprocessing and mining that multi-dimensional historical consumption data of the user, and the portrait of the user is obtained through the further mathematical analysisof the multi-dimensional label data, are achieved.

Description

technical field [0001] The present invention relates to the technical field of portrait modeling, in particular to a multidimensional data-based portrait modeling method and device. Background technique [0002] User portrait, portrait modeling generally includes two modeling types, Profile and Persona, and this application refers specifically to Profile type portrait modeling. Profile-type portrait modeling is more used by operations and data analysts. It is a collection of variables that describe user data. The technical research on user portrait modeling at home and abroad mainly focuses on the combination of statistical analysis and machine learning technology in a certain business field. This application proposes a modeling based on multidimensional data such as user historical consumption data and evaluation data. method. Contents of the invention [0003] Embodiments of the present invention provide a method and device for modeling portraits based on multi-dimensi...
