Embodiment Construction

[0065] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0066] In one embodiment, such as figure 1 As shown, a method for building a chemical accident knowledge map is provided, including the following steps:

[0067] S110. Construct an ontology structure according to logical associations between metadata.

[0068] Wherein, the metadata includes words representing at least two of the name of the hazardous chemical, the category of the hazardous chemical, the hazard characteristic and the inducement of the hazard characteristic.

[0069] Further, the ontology structure is used to represent the logical relationship between the ...

Abstract

The invention relates to a spectrum construction method and device, an accident classification method and device, computer equipment and a medium. The spectrum construction method comprises the following steps: constructing an ontology structure according to a logic association relationship between metadata, wherein the metadata comprises words representing at least two of dangerous chemical names, dangerous chemical categories, dangerous characteristics and dangerous characteristic inducements; clustering the corpus data of the chemical accident to obtain at least one cluster; wherein each clustering cluster comprises a plurality of words with a feature association relationship, and the feature association relationship comprises at least one of a similar association relationship, an opposite association relationship and a causal association relationship; and associating the clustering cluster with metadata in the ontology structure according to the feature association relationship toobtain the chemical accident knowledge graph. By adopting the method, the accuracy of the constructed chemical accident knowledge graph can be improved, and huge manpower and time costs for constructing the chemical accident knowledge graph are avoided.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a map construction method, accident classification method, device, computer equipment and media. Background technique [0002] In recent years, with the development of the Internet, a large amount of data information about hazardous chemical accidents has been collected on the Internet. However, the above information is mainly unstructured data composed of text, which has the characteristics of difficult expansion of data volume and high similarity of keywords. characteristics, it is difficult to train a classifier to classify based on the word features in the text. Therefore, the accurate classification of the text information of hazardous chemical accidents needs to be based on the understanding of the text information, and the understanding of the text information requires a lot of common sense knowledge and domain knowledge, and the representation of the abo...
