Problems solved by technology

Whether a theme map is valid or not needs to be verified. At present, the verification method of theme maps is mainly based on manual verification. Although the current method of manual verification can directly judge the accuracy of theme maps, the current method requires The relationship between the documents in the map is verified one by one. For a large number of documents, this is a huge workload and requires a lot of manpower

Embodiment 1

[0110] refer to figure 1 , in order to solve the problem that traditional thematic map evaluation methods need to consume a lot of manpower and material resources, the present invention proposes an evaluation method for thematic maps, which mainly includes the following steps:

[0111] S1. Use the small-world feature to verify the document classification of thematic maps;

[0112] S2. Verify important documents of thematic maps with scale-free features;

[0113] S3. Perform expert verification on the correlation between topics in the topic map.

[0114] refer to figure 2 , taking the evaluation of the topic map constructed from blog data as an example, to describe steps S1-S3 in detail.

[0115] Said step S1 comprises:

[0116] S11. Judging whether the theme map conforms to the small-world characteristic by the average aggregation coefficient and the average shortest path of the theme map, so as to verify the validity of the theme map document classification, if the avera...

Abstract

The invention discloses an evaluation method, system and device of a theme map. The method of the invention includes the following steps: verifying the document classification of the theme map by using the small-world characteristic; verifying the important documents of the theme map by using the scale-free characteristic ; Carry out expert verification on the correlation between topics in the topic map; the system includes a document classification verification module, an important document verification module and a correlation verification module; the device includes a processor and a memory. The method of the present invention utilizes the small-world characteristic to verify the classification of documents and the scale-free characteristic to verify the important documents of the theme map, so that manual participation is not required when performing document classification verification and important document verification of the theme map, saving manpower overhead. The invention can be widely used in the field of data mining.

Description

technical field [0001] The invention relates to the field of data mining, in particular to a method, system and device for evaluating a theme map. Background technique [0002] Glossary: [0003] Topic map: It is a knowledge representation mode of semantic network. A topic map contains a series of topics, each topic represents a class of concepts, associations are used between topics to represent associations, and associations between topics and resources use occurrences express. [0004] Small-world characteristics: Compared with random networks of the same size, networks that conform to small-world characteristics have higher clustering coefficients and shorter shortest path lengths. [0005] Scale-free feature: the scale-free network has strong heterogeneity, the degree of each node in the network, that is, the distribution of connection status is seriously uneven: a small number of nodes in the network have a very large degree (that is, they have There are a lot of co...
