class RelationExtractionModel extends GenericClassifierModel with ParamsAndFeaturesWritable with HandleExceptionParams with HasSafeAnnotate[GenericClassifierModel]

Extracts and classifies instances of relations between named entities. For this, relation pairs need to be defined with setRelationPairs, to specify between which entities the extraction should be done.

For pretrained models please see the Models Hub for available models.

Example

Relation Extraction between body parts

Define pipeline stages to extract entities

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

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

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

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

val pos_tagger = PerceptronModel.pretrained("pos_clinical", "en", "clinical/models")
  .setInputCols("sentences", "tokens")
  .setOutputCol("pos_tags")

val dependency_parser = DependencyParserModel.pretrained("dependency_conllu", "en")
  .setInputCols("sentences", "pos_tags", "tokens")
  .setOutputCol("dependencies")

val clinical_ner_tagger = MedicalNerModel.pretrained("jsl_ner_wip_greedy_clinical","en","clinical/models")
  .setInputCols("sentences", "tokens", "embeddings")
  .setOutputCol("ner_tags")

val ner_chunker = new NerConverter()
  .setInputCols("sentences", "tokens", "ner_tags")
  .setOutputCol("ner_chunks")

Define the relations that are to be extracted

val relationPairs = Array("direction-external_body_part_or_region",
                      "external_body_part_or_region-direction",
                      "direction-internal_organ_or_component",
                      "internal_organ_or_component-direction")

val re_model = RelationExtractionModel.pretrained("re_bodypart_directions", "en", "clinical/models")
  .setInputCols("embeddings", "pos_tags", "ner_chunks", "dependencies")
  .setOutputCol("relations")
  .setRelationPairs(relationPairs)
  .setMaxSyntacticDistance(4)
  .setPredictionThreshold(0.9f)

val pipeline = new Pipeline().setStages(Array(
  documenter,
  sentencer,
  tokenizer,
  words_embedder,
  pos_tagger,
  clinical_ner_tagger,
  ner_chunker,
  dependency_parser,
  re_model
))

val data = Seq("MRI demonstrated infarction in the upper brain stem , left cerebellum and  right basil ganglia").toDF("text")
val result = pipeline.fit(data).transform(data)

Show results

result.selectExpr("explode(relations) as relations")
 .select(
   "relations.metadata.chunk1",
   "relations.metadata.entity1",
   "relations.metadata.chunk2",
   "relations.metadata.entity2",
   "relations.result"
 )
 .where("result != 0")
 .show(truncate=false)
+------+---------+-------------+---------------------------+------+
|chunk1|entity1  |chunk2       |entity2                    |result|
+------+---------+-------------+---------------------------+------+
