Example Embodiment

[0048] Example 1

[0049] figure 1 This is a flowchart of a method for constructing a knowledge graph of data provided in Embodiment 1 of the present invention. This embodiment can be applied to the case of classifying data. The method can be executed by an apparatus for constructing a knowledge graph of data. The apparatus can use It is implemented in software and / or hardware and can be integrated in local equipment. Specifically, refer to figure 1 , the method includes the following steps:

[0050] S110. Obtain sample data.

[0051] The sample data can be structured data covering multiple industries, involving finance, real estate, medical care, education, etc., or unstructured data. Structure to logically express and implement data, unstructured data is irregular or incomplete data structure, no predefined data model, data that is inconvenient to be represented by two-dimensional database tables, such as office documents, text, images and XML documents, etc. Optionall...

[0060] Embodiment 2

[0061] The second embodiment of the present invention describes the construction process and result of a knowledge graph of data on the basis of the above embodiments, and the form of the knowledge graph takes the form of a tree structure as an example.

[0062] (1) The construction process and results of the knowledge map of ground objects

[0063] According to the definition of the ground object 2, the ground object 2 is divided into the real ground 21 and the virtual ground 22. The position information of the real ground 21 is the position information of the three-dimensional space where we live in our lives, and the judgment of the real ground 21 is relatively easy in practical applications. , when it is determined that the keyword represents the real world, the word meaning of the keyword can be further analyzed with the help of subject knowledge of geography, geographic information system, etc., and the analysis shows that the meaning represented by...

[0077] Embodiment 3

[0078] Figure 7 A flowchart of a method for constructing a knowledge graph of data provided in Embodiment 3 of the present invention, on the basis of the above embodiment, after the knowledge graph corresponding to the sample data is constructed, the knowledge graph is checked and adjusted to obtain A more complete knowledge graph is obtained to provide a more reliable basis for data processing. Specifically, the method includes:

[0079] S341. Acquire actual data.

[0080] The actual data can be different from the sample data, or it can include multiple industries and fields. It is understandable that the more fields and the larger the scale of the actual data, the verification of the knowledge graph corresponding to the sample data. As a result, the higher the reliability, the acquisition method of the actual data is similar to that of the sample data, which will not be repeated here.

[0081] S342. Perform word meaning analysis on the keywords in t...

Abstract

The invention discloses a knowledge map construction method of data, device, apparatus and storage medium, The method comprises: Obtain sample data, performing word meaning analysis on keywords in thesample data, obtaining a first attribute category and a first attribute sub-category corresponding to each of the keywords, determining an association relationship between the first attribute sub-categories according to a preset rule, according to an association relationship between a first attribute class and a first attribute sub-class corresponding to each of the keywords and the first attribute sub-class, constructing a knowledge map corresponding to the sample data, The technical scheme obtains different first attribute categories and first attribute sub-categories corresponding to different keywords through the word meaning analysis of the sample data, solves the problem of singularity of the first attribute categories in the prior art, constructs a knowledge map with more comprehensive information, and realizes more complete classification of the data.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of big data mining, and in particular, to a method, device, device, and storage medium for constructing a data knowledge map. Background technique [0002] With the rapid development of informatization, the world of data explosion has entered the era of big data. How to extract valuable information from big data and transform it into practically available resources to support various complex The business is an important proposition faced by the field of information technology. [0003] Over the past few years, technologies related to big data have continued to develop, and emerging technologies such as cloud computing, machine learning, and natural language processing have been integrated into the field of big data processing, which has played a significant role in promoting the development of big data. However, not all problems can be solved by technical means. The processing of data ...
