Embodiment 1

[0048] figure 1 It is a flow chart of a method for determining an entity-relationship graph provided by Embodiment 1 of the present invention. This embodiment can be applied to the situation of determining an entity-relationship graph based on entities and entity relationships, and the method can be executed by a device for determining an entity-relationship graph , the device is integrated in the server, refer to figure 1 , the method includes the following steps:

[0049] S110. Determine at least one entity in the target data, and extract entity relationships between entities.

[0050] Target data can be data obtained based on set rules, or specific types of data selected according to actual needs, where set rules can be data cleaning, data integration, and data normalization rules to convert unstructured data into structured Structured data to meet the needs of users. Among them, structured data is also called row data, which is logically expressed and realized by a two-d...

Embodiment 2

[0072] figure 2 The flow chart of a method for determining an entity-relationship diagram provided in Embodiment 2 of the present invention is optimized on the basis of the above-mentioned embodiments. Specifically, the method includes the following steps:

[0073] S210. Capture raw data, and analyze and extract data features of the raw data.

[0074] Raw data can be unstructured log data, which can be captured by email or the Internet through script crawlers or data aggregation. Among them, crawlers are a way to automatically capture Internet information. For example, Python crawlers can be used to crawl log data. Or extract data in mail. Data characteristics are the characteristics or characteristics of data, which can reflect the information represented by the data, such as mobile phone number, ID card or WeChat ID. Optionally, after obtaining the original data, preprocess the original data. Preprocessing includes but is not limited to data cleaning and data transformati...

Embodiment 3

[0098] Figure 4 Embodiment 3 of the present invention provides a structural diagram of a device for determining an entity-relationship graph. The device can execute the method for determining an entity-relationship graph described in the above embodiment. Specifically, the device includes:

[0099] The first determination module 410 is configured to determine at least one entity in the target data, and extract entity relationships between entities;

[0100] The second determination module 420 is configured to determine the reliability of each entity relationship;

[0101] The third determination module 430 is configured to determine the target entity relationship and the corresponding target entity pair according to the ranking of the reliability;

[0102] A composition module 440, configured to connect each of the target entity pairs based on each of the target entity relationships, form and store an entity relationship graph.

[0103] Embodiment 3 of the present invention...

Abstract

The invention discloses a method for determining an entity relation diagram, device, server and storage medium, The method comprises: determining at least one entity in the target data, and extracts entity relationships between entities, determining the reliability of each of the entity relationships, according to the ranking of the reliability, A target entity relationship and correspond target entity pairs are determine, As that object entity relation is connected with the object entity pairs, the entity relation diagram is for and stored. The technical proposal solves the problems of storage overhead and tedious process caused by the storage of the existing entity and the relationship data, simplifies the determination process of the entity relation diagram, improves efficiency and saves storage space.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a method, device, server, and storage medium for determining an entity-relationship graph. Background technique [0002] Facing the ever-increasing mass of information, it is particularly important to quickly select the information that is really needed, and classify, extract and reconstruct the information. [0003] In this context, information extraction technology emerges as the times require. In a broad sense, the object of information extraction processing can be text, image, voice or video and other media. In practical applications, text information is usually extracted. Text information extraction is a technology for extracting specified types of entities and relationships from natural language texts. It mainly includes three aspects: processing unstructured natural language texts, selectively extracting specified information in texts, and ...
