Abstract

The invention discloses a knowledge graph element organization method oriented to a time sequence tangent plane. The method comprises the steps of defining a maximum effective time range of a system;organizing entities and relationships, and constructing a time sequence map; obtaining a key point set; and obtaining the tangent plane of the time sequence map, and determining the entity, the relationship and all change processes of the attributes of the entity and the relationship in the effective time range, or the attribute values and states of the entity and the relationship in the key points. The method can reflect the storage time ranges of the vertexes and the edges, the attributes of the vertexes and the edges in different time ranges and the change conditions of the vertexes and theedges, and unified version division is not needed; the state of the atlas at any moment within the effective time range of the atlas can be obtained, all states of a certain graph element are directly obtained, and compared with an incremental graph method, calculation steps are greatly reduced.

Description

technical field

[0001] The invention relates to database technology, in particular to a method for organizing knowledge map elements oriented to time series sections. Background technique

[0002] The knowledge graph is a semantic network that includes entities and relationships. The knowledge graph technology can be used to model entities, relationships and their attributes. The usual knowledge graph is static, and only maintains information about a certain state of entities and relationships, that is, it only reflects the status and attributes of entities and their related relationships at a point in time. However, the real world is in a process of constant movement and development. If a static knowledge map is used to express the evolution process of the attributes, states, and relationships of things over time, there will be the following shortcomings: the attributes of things are changing In the process, for example, a person may change their nationality, and the stati...
