UniNER-7B-type

Description: A UniNER-7B model trained from LLama-7B using the Pile-NER-type data without human-labeled data. The data was collected by prompting gpt-3.5-turbo-0301 to label entities from passages and provide entity tags. The data collection prompt is as follows:

Instruction:
Given a passage, your task is to extract all entities and identify their entity types. The output should be in a list of tuples of the following format: [("entity 1", "type of entity 1"), ... ].

Check our paper for more information. Check our repo about how to use the model.

Comparison with UniNER-7B-definition

The UniNER-7B-type model excels when handling entity tags. It performs better on the Universal NER benchmark, which consists of 43 academic datasets across 9 domains. In contrast, UniNER-7B-definition performs better at processing entity types defined in short sentences and is more robust to type paraphrasing.

Inference

The template for inference instances is as follows:

Prompting template:
A virtual assistant answers questions from a user based on the provided text.
USER: Text: {Fill the input text here}
ASSISTANT: I’ve read this text.
USER: What describes {Fill the entity type here} in the text?
ASSISTANT: (model's predictions in JSON format)

Note: Inferences are based on one entity type at a time. For multiple entity types, create separate instances for each type.
