Embodiment Construction

[0038] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0039] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0040] As an important topic, object similarity is widely used in many practical problems such as fraud detection and identification of potential risks.

[0041] However, the existing method for determining the similarity between objects may have problems such as low efficiency, poor timeliness (eg, poor timeliness due to post-processing and other reasons), an...

Abstract

The embodiment of the invention provides a method and device for determining similarity between objects, and the method comprises the steps: obtaining statistical data of a current object, and enabling the statistical data of the current object to comprise a plurality of primary features related to the behaviors of a target object and the occurrence frequency of each primary feature in the plurality of primary features; calculating a feature value corresponding to each primary feature by utilizing the occurrence frequency of each primary feature; adding the eigenvalues corresponding to all theprimary features in the plurality of primary features to obtain a total eigenvalue corresponding to the current object; calculating a similarity index of the current object and the target object by utilizing the feature number of the plurality of primary features and the total feature value corresponding to the current object; and determining the similarity between the current object and the target object according to the similarity index. By means of the technical scheme, the time consumed for determining the similarity between the current object and the target object can be shortened, and then the similarity determining efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular, to a method and device for determining similarity between objects. Background technique [0002] As an important topic, the similarity between objects is necessary for many practical problems such as link prediction, fraud detection, and collaborative filtering. [0003] At present, the similarity between existing objects is generally determined through a large amount of manpower and material resources. For example, the data of the current object and the data of the target object can be manually compared, and the similarity between the current object and the target object can be determined based on the comparison result. [0004] During the process of implementing the present invention, the inventors found that the following problems exist in the prior art: the existing method for determining the similarity between objects at least has the problem of relatively l...
