Please refer to fig. 3, which is a flowchart illustrating a method for displaying a knowledge graph according to an embodiment of the present invention. It should be noted that the method for displaying a knowledge graph according to the embodiment of the present invention is not limited by fig. 3 and the following specific sequence, and it should be understood that, in other embodiments, the sequence of some steps in the method for displaying a knowledge graph according to the embodiment of the present invention may be interchanged according to actual needs, or some steps in the method may be omitted or deleted. The knowledge graph display method can be applied to the user terminal 100 shown in fig. 1, and the specific process shown in fig. 3 will be described in detail below.

Step S101, a plurality of entities and entity information and relationship information of each entity are obtained.

In the present embodiment, the plurality of entities and the entity information and relationship information of each entity are provided by the backend server 200.

Wherein, the entity can be an object with special meaning or strong reference, such as a name of a person, a name of a place, a name of an organization and so on; the entity information comprises entity types and identity information, and the entity types are used for representing the categories of the entities, such as cities, middle-aged people, young people and the like; the Identity information can be identified by an ID (Identity document) number; the relationship information comprises a relationship identifier, a relationship identifier code, identity information of the entity and identity information of the target entity; the relationship identification is used for representing the relationship between one type of entity and another type of entity, and the relationship can be colleagues, classmates, friends and the like; the relationship identification code is used for distinguishing the same type of entity with the same relationship identification.

Step S102, grouping a plurality of entities according to the entity information and the relationship information of each entity to obtain a plurality of entity groups; wherein, the entities with the same kind of entity information and the relation information are in the same group.

In this embodiment, the user terminal 100 divides the plurality of entities into a plurality of entity groups according to the entity information and the relationship information of each entity provided by the backend server 200, and the entity information and the relationship information of the entities in each group of entity groups are similar.

Specifically, referring to fig. 4, a flow chart of the substeps of step S102 is shown, and step S102 includes the following substeps:

step S1021, a plurality of entities are classified according to entity types, and a plurality of initial entity groups with different types are obtained.

Step S1022, the entities with the same relationship identifier in the initial entity group are grouped into one group, so as to obtain a plurality of entity groups.

In this embodiment, the user end 100 may first divide entities of the same entity type into one group to obtain a plurality of initial entity groups; and then according to the relationship identification, dividing the entities with the same relationship identification into a group from the plurality of entity groups to obtain a plurality of entity groups. It is understood that entities of the same entity type are not grouped in the same entity group if the relationship identifications are different. Only entities with the same entity type and relationship identity are assigned to the same entity group (i.e., entities with homogeneous entity information and relationship information).

As shown in fig. 5, a schematic display diagram of a knowledge graph provided in an embodiment of the present invention illustrates three types of entities, where an entity with a circular shape is a first type of entity, it can be understood that the entity type of the first type of entity is human, an entity with a square shape is a second type of entity, it can be understood that the entity type of the second type of entity is cat, an entity with a rectangular shape is a third type of entity, and it can be understood that the entity type of the third type of entity is dog. The user end 100 can divide people, cats and dogs into three initial entity groups according to entity types, that is, circular entities are all allocated to the same group, square entities are all allocated to the same group, and rectangular entities are all allocated to the same group.

The relationship among humans, cats, and dogs shown in the schematic diagram of fig. 5 is also classified into three relationships, the first relationship is that humans only feed cats, the second relationship is that humans only feed dogs, and the third relationship is that humans both feed cats and dogs. Namely, the relationship information of the entity person comprises a first relationship identifier (namely, a first relationship) of the person and the cat and a second relationship identifier (namely, a second relationship) of the person and the dog, the relationship information of the entity dog comprises a second relationship identifier of the person and the dog, and the relationship information of the entity cat comprises a first relationship identifier of the person and the cat. The user end 100 further groups the good initial entity groups according to the relationship identifier of each entity, that is, the user end 100 divides the initial entity group of the entity type person into entity groups again according to the first relationship identifier and the second relationship identifier of the person, because the relationship information of a part of the entities in the initial entity group of the entity type person only includes the first relationship identifier, the relationship information of another part of the entities only includes the first relationship identifier, and the relationship information of another part of the entities includes the first relationship identifier and the second relationship identifier, the part of the entities only having the first relationship identifier can be divided into one entity group, the part of the entities only having the second relationship identifier can be divided into another entity group, and the part of the entities having the first relationship identifier and the second relationship identifier can be divided into another entity group. Because the initial entity groups with the entity types of cat and dog have only one relationship identifier, the initial entity group with the entity type of cat is also the final entity group, and the initial entity group with the entity type of dog is also the final entity group, so that the initial entity group and the final entity group are divided into five entity groups in total.

In this embodiment, the entities having the same relationship identifier in the initial entity group are grouped into one group, and it can be understood that the same relationship identifier may be a plurality of relationship identifiers, that is, if a plurality of relationship identifiers of one of the entities in the initial entity group are the same as a plurality of relationship identifiers of another entity, the two entities may be grouped into one group. If the relationship identifications of one entity in the initial entity group are only partially identical to the relationship identifications of another entity, the two entities are not grouped into one group.

In this embodiment, in order to facilitate the user to identify different types of entities, each initial entity group may be displayed in different colors. For example, entities with entity type of person are all displayed in green, entities with entity type of cat are all displayed in blue, and entities with entity type of dog are all displayed in red.

Step S103, generating a knowledge graph according to the relation information of a plurality of entity groups and each entity.

In this embodiment, after the user end 100 divides the plurality of entities into a plurality of entity groups, the plurality of entity groups are sequentially arranged at different vertical coordinate positions according to the relationship information of each entity, and finally a knowledge graph is generated.

Referring to fig. 6, a schematic view of a sub-process flow that can be implemented in step S103 is shown, where step S103 includes the following sub-processes:

step S1031, randomly selecting an initial entity group from the plurality of entity groups to arrange at an initial position.

Step S1032 selects a first entity group having the same relationship identifier and a different entity type from the initial entity group from the remaining entity groups, and arranges the first entity group close to the initial position.

Step S1033, selecting a second entity group having the same relationship identifier and a different entity type as the first entity group from the unselected entity groups, and arranging the second entity group close to the position where the first entity group is arranged; and repeating the operation until all entity groups are arranged.

In this embodiment, after obtaining the plurality of entity groups, the user end 100 randomly selects an initial entity group from the plurality of entity groups to be placed at an initial position. Here, the initial position may be understood as a position having an ordinate of 0. And the multiple entities in the initial entity group are also randomly arranged in a row, namely the vertical coordinates of the multiple entities are all 0, and the horizontal coordinates are different. The distance between the plurality of entities in the initial entity group may be set to 100. After all the entities in the initial entity group are arranged at the initial position, the user terminal 100 selects a first entity group having the same relationship identifier and different entity types as the initial entity group from the remaining entity groups, and arranges the first entity group close to the initial position. The first entity group may be one group or multiple groups, and the position difference between the first entity group and the initial entity group is that the ordinate of the first entity group is different from the ordinate of the initial entity group, and the first entity group may be arranged at a position where the ordinate is 500 steps away from the initial position. And the placing positions of each entity in the first entity group are correspondingly arranged according to the entities in the initial entity group. After each entity in the first entity group is arranged, a second entity group with the same relationship identification and different entity types as the first entity group is selected from the unselected entity groups, and the second entity group is arranged close to the first entity group. The second entity group may be one group or multiple groups, and may be arranged at a position of 500 step lengths from the arrangement position of the first entity group on the ordinate, and the arrangement position of each entity in the second entity group is arranged corresponding to the entity in the first entity group. If there are any unselected entity groups, the user end 100 repeats the operation of step S1033 until all entity groups are arranged.

It can be understood that, as shown in fig. 5, entities of which the entity types are human, the relationship identification is human and cat, and the relationship identification is human and dog are divided into an entity group a, entities of which the entity types are cat, the relationship identification is human and cat are divided into an entity group B, entities of which the entity types are dog, entities of which the relationship identification is human and dog are divided into an entity group C, entities of which the entity types are human, the relationship identification is human and cat are divided into an entity group D, and entities of which the entity types are human, the relationship identification is human and dog are divided into an entity group E.

The user end 100 may first arrange the entity group a at an initial position (i.e., a position with a vertical coordinate of 0), where the entity group a includes an entity a, an entity B, and an entity C, the entity a may be arranged at a position with a coordinate of (0, 0), the entity B may be arranged at a position with a coordinate of (100, 0), and the entity C may be arranged at a position with a coordinate of (200, 0). The entity group A and the entity group B have the same relationship identification of people and cats, and the entity types of the entity group A and the entity group B are different, so that the entity group B is a first entity group; since the entity group a and the entity group C have the same person-dog relationship identification, and the entity types of the entity group a and the entity group C are different, all the entity group C is also the first entity group. The user terminal 100 may arrange the entity group a at a position with an ordinate of 500 (i.e., a position close to the initial position), and arrange the entity group B at a position with an ordinate of-500 (i.e., a position close to the initial position). The entity group B comprises an entity 1, an entity 2 and an entity 3, and if the entity 1 and the entity A have the same first relationship identification code, the entity 1 and the entity A have a direct corresponding relationship; if the entity 2 and the entity B have the same second relationship identification code, the entity 2 and the entity B have a direct corresponding relationship; if the entity 3 and the entity C have the same second relationship identification code, the entity 3 and the entity C have a direct corresponding relationship; then, entity 1 may correspond to the position arrangement of entity a, entity 1 may be arranged at the position with the coordinates (0, 500), entity 2 may be arranged at the position with the coordinates (100, 500), and entity 3 may be arranged at the position with the coordinates (200, 500). Similarly, the entity group C includes an entity 4, an entity 5 and an entity 6, the entity 4 corresponds to the entity a, the entity 5 corresponds to the entity B, and the entity 6 corresponds to the entity C, the entity 4 may be arranged at a position with coordinates (0, -500), the entity 5 may be arranged at a position with coordinates (100, -500), and the entity 6 may be arranged at a position with coordinates (200, -500). Since the entity group D and the entity group B have the same relationship identifier between a person and a cat, and the entity types of the entity group B and the entity group D are different, the entity group D is the second entity group, the user terminal 100 can arrange the entity group D at a position (i.e., a position close to the entity group B) with a vertical coordinate of 1000, and the arrangement position principle of each entity in the entity group D can refer to the arrangement principle of the entities in the entity group B and the entity group C, which is not described herein in detail. Since the entity group E and the entity group C have the same relationship identifier between people and dogs, and the entity types of the entity group C and the entity group E are different, the entity group E is the third entity group, the user end 100 can arrange the entity group E at a position (i.e., a position close to the entity group C) with a vertical coordinate of-1000, and the arrangement position principle of each entity in the entity group E can refer to the arrangement principle of the entities in the entity group B and the entity group C, which will not be described herein in detail.

It can be understood that the relationship information of the entity 1 includes the first relationship identifier, the first relationship identifier code, the identity information of the entity 1 and the identity information of the entity a, and the relationship information of the entity a also includes the first relationship identifier, the first relationship identifier code, the identity information of the entity 1 and the identity information of the entity a; the relationship information of the entity 2 comprises a first relationship identifier, a second relationship identifier code, the identity information of the entity 2 and the identity information of the entity B, and the relationship information of the entity B also comprises the first relationship identifier, the second relationship identifier code, the identity information of the entity 2 and the identity information of the entity B; similarly, the relationship information of the entity 3, the entity 4, the entity 5, the entity 6 and the entity C can be obtained, and will not be described in a repeated manner.

And step S104, displaying the knowledge graph.

In this embodiment, the generated knowledge graph is displayed on the display interface 140 of the user, so that the user can conveniently view the knowledge graph.

Referring to fig. 7, which is another schematic flow chart of a knowledge graph displaying method according to an embodiment of the present invention, the knowledge graph displaying method shown in fig. 7 further includes the following steps based on the knowledge graph displaying method shown in fig. 3:

and step S105, responding to the operation of the user on the target relation identification item to obtain the target relation identification.

In this embodiment, the display interface 140 of the user end 100 is provided with a relationship identifier list, where the relationship identifier list includes a plurality of relationship identifier items, and each relationship identifier item corresponds to one relationship identifier. The user can click the target relationship identification item to be known through the mouse, and the processor 120 of the user terminal 100 responds to the click operation to obtain the target relationship identification corresponding to the target relationship identification item.

And step S106, marking and displaying the entity with the target relation identifier.

In this embodiment, after obtaining the target relationship identifier, the user obtains all entities with the target relationship identifier, and highlights all the entities with the target relationship identifier, so that the user can see the entity corresponding to the target relationship identifier from the knowledge graph conveniently.

And step S107, responding to the click operation of the user on the target entity in the displayed knowledge graph, and acquiring the identity information of the target entity.

In this embodiment, the user may also directly click the target entity in the knowledge graph displayed on the display interface 140 through a mouse, and the processor 120 of the user terminal 100 may respond to the click operation to obtain the identity information of the target entity.

And step S108, marking and displaying the target entity and the entity with the same relation identification with the target entity.

In this embodiment, since the relationship information of the entities with the same relationship identifier includes the identity information of the same entity, the processor 120 highlights the entity with the identity information of the target entity in the relationship information after obtaining the identity information of the target entity, so as to facilitate the user to view.
