+# codeswitch-spaeng-ner-lince
+This is a pretrained model for **Name Entity Recognition** of `spanish-english` code-mixed data used from [LinCE](https://ritual.uh.edu/lince/home)
+
+This model is trained for this below repository. 
+
+[https://github.com/sagorbrur/codeswitch](https://github.com/sagorbrur/codeswitch)
+
+To install codeswitch:
+
+```
+pip install codeswitch
+```
+
+## Name Entity Recognition of Spanish-English Mixed Data
+
+* **Method-1**
+
+```py
+
+from transformers import AutoTokenizer, AutoModelForTokenClassification, pipeline
+
+tokenizer = AutoTokenizer.from_pretrained("sagorsarker/codeswitch-spaeng-ner-lince")
+
+model = AutoModelForTokenClassification.from_pretrained("sagorsarker/codeswitch-spaeng-ner-lince")
+
+ner_model = pipeline('ner', model=model, tokenizer=tokenizer)
+
+ner_model("put any spanish english code-mixed sentence")
+
+```
+
+* **Method-2**
+
+```py
+from codeswitch.codeswitch import NER
+ner = NER('spa-eng')
+text = "" # your mixed sentence 
+result = ner.tag(text)
+print(result)
+```
