class Resolution2Chunk extends AnnotatorModel[Resolution2Chunk] with HasSimpleAnnotate[Resolution2Chunk]

This annotator converts 'Resolution' type annotations into 'CHUNK' type to create new chunk-type column, compatible with annotators that use chunk type as input.

Example

Define dataset

val testDS = Seq(
"Has a past history of gastroenteritis and stomach pain, however patient shows no stomach pain now. " +
"We don't care about gastroenteritis here, but we do care about heart failure. " +
"Test for asma, no asma.").toDF("text")

Define a pipeline

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

val sbert_embedder =  BertSentenceEmbeddings
 .pretrained("sbiobert_base_cased_mli","en","clinical/models" )
 .setInputCols(Array("ner_chunk"))
 .setOutputCol("sentence_embeddings")
 .setCaseSensitive(false)

val resolver = SentenceEntityResolverModel
 .pretrained("sbiobertresolve_rxnorm_augmented", "en", "clinical/models")
 .setInputCols(Array("sentence_embeddings"))
 .setOutputCol("resolve")

val resolver2chunk = new Resolution2Chunk()
 .setInputCols(Array("resolve"))
 .setOutputCol("chunk")
val pipeline = new Pipeline().setStages(Array(documentAssembler, sbert_embedder, resolver, resolver2chunk)).fit(testDS)

val result = pipeline.transform(testDS).selectExpr("chunk.result","chunk.annotatorType").show(false)
