Problems solved by technology

Also for multi-attribute requirements, such as a computer with specific parameter value requirements for both the CPU and the graphics card, for this type of service / product matching, it is too simple and strict if the Boolean method is used

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] The present invention is a method for calculating the matching degree of service sortable precise attributes in the form of one-way chains, such as figure 1 As shown, it mainly includes four parts: the establishment of sortable attributes, the construction of sorting rules for attributes, the construction of formulas for calculating attribute matching degrees, and the calculation of comprehensive matching degrees.

[0035] (1) The sortable attribute is established

[0036] Which properties are eligible to use this method is established by the following three main rules:

[0037] ① As far as requirements are concerned, this type of attribute does not need to be absolutely strict. That is, users can accept services / products that cannot be strictly matched by this attribute;

[0038] ② The parameter value of the attribute is precise. The precision here...

Abstract

The invention relates to a method for calculating the matching degree of sortable precise attributes of services in the form of a one-way chain. In traditional production, manufacturing and e-commerce platforms, the parameters of some attributes of services / products are accurate. Requirements and attributes require absolute unity or compatibility of the parameters of the two. Some products or services that can also meet user needs are eliminated from the candidate sample set. According to the values ​​of the parameters of these attributes, the present invention sorts the attributes of the candidate services / products to form a one-way sequence, and provides a formula for calculating the similarity between each node on the chain and the target node. According to the similarity calculation formula, the matching degree between each attribute of the requirement and each attribute of the service / product can be calculated, and then the overall matching degree of the requirement and the service / product can be obtained by using a weighted method. This method is highly flexible and more in line with the essential needs of users, and is an efficient, fast, and demand-oriented matching calculation method.

Description

technical field [0001] The present invention designs a method for calculating the matching degree of sortable precise attributes of services in the form of a one-way chain. The method is oriented to calculating the matching degree of some attributes whose parameter values ​​are accurate and can be sorted. Therefore, in the matching process of services and products with such attributes, the matching method is too strict and the sample set size is excessively reduced, which belongs to the manufacturing field. Background technique [0002] In today's society, the form of network services centered on cloud thinking is becoming more and more mature. Various cloud computing, manufacturing, and e-commerce platforms affect our lives all the time. These platforms mainly operate and sell various services / products. The description of these services / products is very important, and a reasonable description method will greatly affect the operation plan of other modules of the platform, ...
