TNER 24

Hello,

I am developing a library for PII detection and anonymization and am evaluating
tner/roberta-large-ontonotes5 as an optional local NER model.

The checkpoint revision evaluated is:

0bce50f7884d5bb040469c907c897d4b061ccbb4

The library will not bundle or redistribute the model. Before deciding whether
this model can be recommended for production use, I need to understand its
licensing accurately.

The model card does not currently declare a license. I found that:

• the T-NER software repository is MIT licensed;
• the roberta-large base model is marked MIT;
• this checkpoint was fine-tuned using tner/ontonotes5;
• OntoNotes 5.0 is distributed under an LDC agreement.

Could you please clarify:

1. What license covers the model checkpoint weights?
2. What license covers the tokenizer and configuration files?
3. Is commercial inference with this checkpoint permitted?
4. May downstream users redistribute or mirror the checkpoint?
5. Do OntoNotes/LDC restrictions apply to users who only use the checkpoint
   and never access or redistribute the OntoNotes dataset?
6. Are attribution or notice requirements applicable?
7. Did the training organization have permission to publish the checkpoint for
   these uses?

If the checkpoint is intended to be MIT licensed, would you be willing to add
an SPDX license: mit field and a model-specific license or notice file to
this repository?

Thank you.
