UniNER-7B-definition

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

Comparison with UniNER-7B-type

The UniNER-7B-type model, trained on Pile-NER-type, excels in recognizing common and short NER tags (e.g., person, location) and performs better on NER datasets. On the other hand, UniNER-7B-definition demonstrates superior capabilities in understanding short-sentence definitions of entity types. Additionally, it exhibits enhanced robustness against variations in type paraphrasing.

Inference

The template for inference instances is as follows:

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