Embodiment 1
[0056] This embodiment provides an analysis method for evaluation data, such as figure 1 As shown, this embodiment includes:
[0057]Step 101: Obtain user evaluation data, the evaluation data includes product evaluation elements and the user's first evaluation score for the evaluation elements;
[0058] Preferably, the evaluation data may include evaluation elements of all products and first evaluation scores of users on the evaluation elements.
[0059] Step 102: clustering the evaluation elements;
[0060] Step 103: Use the first evaluation score to perform parameter estimation on the evaluation elements of each cluster, and obtain the second evaluation score of each evaluation element cluster, and the second evaluation score is based on each cluster The weighted average obtained by the first evaluation score of the evaluation element and the user's rating weight.
[0061] In this embodiment, the user's rating weight is used to reflect the bias of user ratings, and the fi...
Embodiment 2
[0088] This embodiment also provides an analysis device for evaluating data, such as figure 2 As shown, this embodiment includes:
[0089] An acquisition module 21, configured to acquire user evaluation data, the evaluation data including product evaluation elements and the user's first evaluation score for the evaluation elements;
[0090] A clustering module 22, configured to cluster the evaluation elements;
[0091] The calculation module 23 is used to estimate the parameters of the evaluation elements of each cluster by using the first evaluation score to obtain the second evaluation score of each evaluation element cluster, and the second evaluation score is based on each A weighted average obtained from the first evaluation score of a clustered evaluation element and the user's evaluation weight.
[0092] In this embodiment, the user's rating weight is used to reflect the bias of user ratings, and the first evaluation score is used to estimate the parameters of each c...
Embodiment 3
[0104] This embodiment also provides an analysis system 50 for evaluating data, such as Figure 5 As shown, this embodiment includes:
[0105] Network interface 51 , processor 52 , input device 53 , memory 54 , hard disk 55 , and display device 56 . The above-mentioned various interfaces and devices may be interconnected through a bus architecture. The bus architecture can be buses and bridges that can include any number of interconnections. Various circuits, specifically one or more central processing units (CPUs), represented by processor 52, and one or more memories, represented by memory 54 are connected together. The bus architecture can also connect together various other circuits such as peripherals, voltage regulators, and power management circuits. It can be understood that a bus architecture is used to implement connection communication between these components. In addition to the data bus, the bus architecture also includes a power bus, a control bus and a statu...
