class ZeroShotRelationExtractionModel extends MedicalBertForSequenceClassification with RelationEncoding with HasEngine

ZeroShotRelationExtractionModel implements zero shot binary relations extraction by utilizing BERT transformer models trained on the NLI (Natural Language Inference) task. The model inputs consists of documents/sentences and paired NER chunks, usually obtained by RENerChunksFilter. The definitions of relations which are extracted is given by a dictionary structures, specifying a set of statements regarding the relationship of named entities. These statements are automatically appended to each document in the dataset and the NLI model is used to determine whether a particular relationship between entities.

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

val zeroShotRE = ZeroShotRelationExtractionModel.pretrained()
  .setInputCols("token", "document")
  .setOutputCol("label")

For available pretrained models please see the Models Hub.

Example

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

val tokenizer = new Tokenizer()
  .setInputCols(Array("document"))
  .setOutputCol("tokens")

val sentencer = new SentenceDetector()
  .setInputCols(Array("document"))
  .setOutputCol("sentences")

val embeddings = WordEmbeddingsModel

val nerTagger = MedicalNerModel
  .pretrained("ner_clinical", "en", "clinical/models")
  .setInputCols(Array("sentences", "tokens", "embeddings"))
  .setOutputCol("nerTags")

val nerConverter = new NerConverter()
  .setInputCols(Array("sentences", "tokens", "nerTags"))
  .setOutputCol("nerChunks")

val dependencyParser = DependencyParserModel
  .pretrained("dependency_conllu", "en")
  .setInputCols(Array("document", "posTags", "tokens"))

  .setMaxSyntacticDistance(4)
  .setDocLevelRelations(false)
  .setInputCols(Array("nerChunks", "dependencies"))
  .setOutputCol("RENerChunks")

      "IMPROVE" -> Array("{TREATMENT} improves {PROBLEM}.", "{TREATMENT} cures {PROBLEM}."),
      "REVEAL" -> Array("{TEST} reveals {PROBLEM}.")
      ))
  .setPredictionThreshold(0.9f)
  .setMultiLabel(false)
  .setInputCols(Array("sentences", "RENerChunks"))
  .setOutputCol("relations)

val pipeline = new Pipeline()
  .setStages(Array(

    tokenizer,
    embeddings,
    posTagger,
    nerTagger,

val model = pipeline.fit(Seq("").toDS.toDF("text"))
val results = model.transform(
  Seq("Paracetamol can alleviate headache or sickness. An MRI test can be used to find cancer.").toDS.toDF("text"))

    Instead of 1 class per sentence (if inputCols is sentence) output 1 class per document by averaging probabilities in all sentences. Due to max sequence length limit in almost all transformer models such as BERT (512 tokens), this parameter helps feeding all the sentences into the model and averaging all the probabilities for the entire document instead of probabilities per sentence.
