The bert-base-NER model is a fine-tuned BERT model that achieves state-of-the-art performance on the CoNLL-2003 Named Entity Recognition task. It was trained on the English version of the standard CoNLL-2003 dataset and recognizes four types of entities: location, organization, person, and miscellaneous. The model occasionally tags subword tokens as entities and post-processing of results may be necessary to handle these cases.

You can use cURL or any other http client to run inferences:

```bash
curl -X POST \
    -d '{"input": "My name is John Doe and I live in San Francisco."}'  \
    -H "Authorization: bearer $(deepctl auth token)"  \
    -H 'Content-Type: application/json'  \
    'https://api.deepinfra.com/v1/inference/dslim/bert-base-NER'
```

which will give you back something similar to:

```json
{
  "results": [
    {
      "entity_group": "B-PER",
      "score": 0.9997528195381165,
      "word": "John",
      "start": 11,

    },

You can use our command-line tool [deepctl](/docs/getting-started) to run
inferences:

```bash
deepctl infer \
    -m 'dslim/bert-base-NER'  \
    -i 'input=My name is John Doe and I live in San Francisco.'
```

which will give you back something similar to:

```json
{
  "results": [
    {
      "entity_group": "B-PER",
      "score": 0.9997528195381165,
      "word": "John",
      "start": 11,
      "end": 15
    },
    {
      "entity_group": "I-PER",
      "score": 0.9995835423469543,
      "word": "Doe",
      "start": 16,
      "end": 19
    },
    {
      "entity_group": "B-LOC",
      "score": 0.9997485280036926,
      "word": "San",
      "start": 34,

    },
    {
      "entity_group": "I-LOC",
      "score": 0.9994599223136902,
      "word": "Francisco",
      "start": 38,

  }
}
