class BertForAssertionClassification extends AnnotatorModel[BertForAssertionClassification] with HasSimpleAnnotate[BertForAssertionClassification] with WhiteAndBlackListParams with HasEngine with WriteTensorflowModel with WriteOnnxModel with HasFeatures with CheckLicense

BertForAssertionClassification extracts the assertion status from text by analyzing both the extracted entities and their surrounding context.

This classifier leverages pre-trained BERT models fine-tuned on biomedical text (e.g., BioBERT) and applies a sequence classification/regression head (a linear layer on the pooled output) to support multi-class document classification.

Key features:

  • Accepts DOCUMENT and CHUNK type inputs and produces ASSERTION type annotations.
  • Emphasizes entity context by marking target entities with special tokens (e.g., [entity]), allowing the model to better focus on them.
  • Utilizes a transformer-based architecture (BERT for Sequence Classification) to achieve accurate assertion status prediction.

Input Example: 

This annotator preprocesses the input text to emphasize the target entities as follows:
   [CLS] Patient with [entity] severe fever [entity].

Pretrained models can be loaded with pretrained of the companion object:

val assertion = BertForAssertionClassification.pretrained()
  .setInputCols("sentence", "chunk")
  .setOutputCol("assertion")

Models from the HuggingFace 🤗 Transformers library are also compatible with Spark NLP 🚀. The Spark NLP Workshop example shows how to import them https://github.com/JohnSnowLabs/spark-nlp/discussions/5669.

Example

val documentAssembler = new DocumentAssembler()
  .setInputCol("text")
  .setOutputCol("document")

val sentenceDetector = new SentenceDetector()
  .setInputCols("document")
  .setOutputCol("sentence")

val tokenizer = new Tokenizer()
  .setInputCols("sentence")
  .setOutputCol("token")

val wordEmbeddings = WordEmbeddingsModel.pretrained("embeddings_clinical", "en", "clinical/models")
  .setInputCols(Array("sentence", "token"))
  .setOutputCol("embeddings")

val clinicalNer = MedicalNerModel.pretrained("ner_clinical", "en", "clinical/models")
  .setInputCols(Array("sentence", "token", "embeddings"))
  .setOutputCol("ner")

val nerConverter = new NerConverterInternal()
  .setInputCols(Array("sentence", "token", "ner"))
  .setOutputCol("ner_chunk")

val assertion = BertForAssertionClassification.pretrained()
  .setInputCols("sentence", "ner_chunk")
  .setOutputCol("assertion")

val pipeline = new Pipeline().setStages(Array(
  documentAssembler, sentenceDetector, tokenizer, wordEmbeddings, clinicalNer, nerConverter, assertion
))
val text ="""Patient with severe fever and sore throat. He shows no stomach pain and he maintained on an epidural
|and PCA for pain control. He also became short of breath with climbing a flight of stairs. After CT, lung tumor
|located at the right lower lobe. Father with Alzheimer.""".stripMargin

val data = Seq(text).toDF("text")
val result = pipeline.fit(data).transform(data)
result.selectExpr("explode(assertion) as assertion").show(false)
