    slots:
      - target
      - rel_type

    multivalued: true

    required: true

for below input

"""
Tesla is a company that manufactures electric vehicles. Elon Musk is the CEO of Tesla.
The Model S is a premium electric car. It uses lithium-ion batteries and has autopilot features.
"""

output

{
  "input_id": null,
  "input_title": null,
  "input_text": "\nTesla is a company that manufactures electric vehicles. Elon Musk is the CEO of Tesla.\nThe Model S is a premium electric car. It uses lithium-ion batteries and has autopilot features.\n",
  "raw_completion_output": "entities: [\"Tesla\", \"electric vehicles\", \"Elon Musk\", \"CEO\", \"Model S\", \"premium electric car\", \"lithium-ion batteries\", \"autopilot features\"]",
  "prompt": "From the text below, extract the following entities in the following format:\n\nname: <The name or label of the entity>\ndescription: <A detailed description of the entity>\ntype: <Category or type of entity (e.g., Company, Person, Product)>\nattributes: <List of key-value attribute pairs describing the entity>\nrelationships: <Relationships from this entity to other entities in describe what they are related to>\n\n\nText:\n[Tesla, electric vehicles, Elon Musk, CEO, Model S, premium electric car, lithium-ion batteries, autopilot features]\n\n===\n\n",
  "extracted_object": {
    "entities": [
      {
        "name": "Autopilot features",
        "description": "Advanced driver-assistance technologies integrated into Tesla vehicles like the Model S for semi-autonomous driving.",
        "type": "Technology/Feature",
        "attributes": null,
        "relationships": null
      }
    ]
  },
  "named_entities": []
}

I am unable to understand why am I not getting 8 extracted_object in entities. also why attributes and relationships is null, How can I fix? Anyone help would be very helpful for me.

Hi @shivshankarkeshari - here are some tips:

• OntoGPT expects multivalued entities to be semicolon-delimited, so you'll need to include that detail in a class description whenever you're extracting something multivalued. See below for an example.
• The ExtractionResult class is already imported through the core schema you've included in the imports, so it doesn't need to be defined here. In fact, most of the slots here don't need to be redefined.
• The more specific you can be in the template about what you're trying to extract, the better.

Something like the following should work:

classes:
  EntitySet:
    tree_root: true
    attributes:
      entities:
        range: Entity
        multivalued: true
        description: >-
          A semicolon-separated list of entities in the input text.
          For each, please include a description of the entity and its type (from Company, Person, or Product)

  Entity:
    description: An entity.

That's a very simplified version - please see the other templates in the templates directory here in the repo for many other examples.
