Feature Description

"Delete Entity" is used to remove unwanted entity types from the graph database. Two deletion methods are provided here. The [Delete Entity] GPA tool is recommended for batch deletion or conditional deletion:

Method 1: After connecting to the graph database, select the entity type to be deleted in the Graph Manager entity list, right-click and choose the "Delete" option.

Method 2: Toolbox->Knowledge Graph->Delete Entity. Double-click directly or drag the tool to the Model Builder window, then double-click the function icon.

Steps

1. Set graph database connection information including database type, address, username, and password. After completing the fields, click the "Join" button. The successful connection message will prompt: "Entity types retrieved, please add and select";
2. Click the "+" button to add entity types to be deleted;
3. When conditions are empty, all data under the target entity type will be deleted by default. To delete partial data under the entity type, add conditional statements in the format: attributeName:'attributeValue' (e.g., ENTITYNAME:'Transportation'). For multiple attribute values, separate them with commas.
4. Click the "Execute" button. After execution completes, the Graph Manager will automatically remove the entity type.
