class ContextualAssertion extends AnnotatorModel[ContextualAssertion] with HasSimpleAnnotate[ContextualAssertion] with HandleExceptionParams with HasSafeAnnotate[ContextualAssertion] with CheckLicense

An annotator model for contextual assertion analysis.

This model identifies contextual cues within text data, such as negation, uncertainty, and assertion. It is used clinical assertion detection, etc. It annotates text chunks with assertions based on configurable rules, prefix and suffix patterns, and exception patterns.

Example

Define pipeline stages to extract entities

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

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

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

val embedder = WordEmbeddingsModel
  .pretrained("embeddings_clinical", "en", "clinical/models")
  .setInputCols(Array("sentences", "tokens"))
  .setOutputCol("embeddings")

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

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

Define Contextual Assertion rules that are to be searched for in the text

   val contextualAssertion = new ContextualAssertion()
    .setInputCols(Array("sentences", "tokens","nerChunks"))
    .setOutputCol("assertion")
    .setScopeWindow(2,2)
    .setPrefixRegexPatterns(Array("\\b(no|without|denies|never|none|free of|negative for|not include)\\b"))
    .setSuffixRegexPatterns(Array("\\b(free of|negative for|absence of|absence|not|neither|rule out)\\b"))
    .setPrefixPatterns(Array("not","never"))
    .setSuffixPatterns(Array("no","never"))
    .setCaseSensitive(false)
    .setAssertion("absent")

val flattener = new Flattener()
  .setInputCols("assertion")
  .setExplodeSelectedFields(Map("assertion" -> Array("result",
                                                     "metadata.ner_chunk as ner_chunk ",
                                                     "metadata.ner_label as ner_label")))

                   tokenizer,
                   embedder,
                   nerTagger,
                   nerConverter,
                   contextualAssertion,
                   flattener
              )).fit(testDataSet)
