New Clinical NER Models

We have three new clinical NER models.

ner_deid_subentity_augmented_i2b2 : This model annotates text to find protected health information(PHI) that may need to be removed. It is trained with 2014 i2b2 dataset (no augmentation applied) and can detect MEDICALRECORD, ORGANIZATION, DOCTOR, USERNAME, PROFESSION, HEALTHPLAN, URL, CITY, DATE, LOCATION-OTHER, STATE, PATIENT, DEVICE, COUNTRY, ZIP, PHONE, HOSPITAL, EMAIL, IDNUM, SREET, BIOID, FAX, AGE entities.

Example :

...
deid_ner = MedicalNerModel.pretrained("ner_deid_subentity_augmented_i2b2", "en", "clinical/models") \
      .setInputCols(["sentence", "token", "embeddings"]) \
      .setOutputCol("ner")
...

results = ner_model.transform(spark.createDataFrame([["A. Record date : 2093-01-13, David Hale, M.D., Name : Hendrickson, Ora MR. # 7194334 Date : 01/13/93 PCP : Oliveira, 25 years old, Record date : 1-11-2000.

New Relation Extraction Model

We are releasing new redl_nihss_biobert relation extraction model that can relate scale items and their measurements according to NIHSS guidelines.

    .setPredictionThreshold(0.5)\
    .setInputCols(["re_ner_chunks", "sentences"]) \

sbiobertresolve_ndc : This model maps clinical entities and concepts (like drugs/ingredients) to National Drug Codes using sbiobert_base_cased_mli Sentence Bert Embeddings. Also, if a drug has more than one NDC code, it returns all available codes in the all_k_aux_label column separated by | symbol.

     .setInputCols(["sentence_embeddings"]) \
     .setOutputCol("loinc_code")\

Updated RxNorm Sentence Entity Resolver Model

We have updated sbiobertresolve_rxnorm_augmented model training on an augmented version of the dataset used in previous versions of the model.

New Shift Days Feature in StructuredDeid Deidentification Module

Now we can shift n days in the structured deidentification when the column is a Date.

Example :

 df = spark.createDataFrame([
            ["Juan García", "13/02/1977", "711 Nulla St.", "140", "673 431234"],
            ["Will Smith", "23/02/1977", "1 Green Avenue.", "140", "+23 (673) 431234"],
            ["Pedro Ximénez", "11/04/1900", "Calle del Libertador, 7", "100", "912 345623"]
        ]).toDF("NAME", "DOB", "ADDRESS", "SBP", "TEL")

 obfuscator = StructuredDeidentification(spark=spark, columns={"NAME": "ID", "DOB": "DATE"},
                                                      columnsSeed={"NAME": 23, "DOB": 23},

New Multiple Chunks Merge Ability in ChunkMergeApproach

Updated ChunkMergeApproach to admit N input cols (.setInputCols("ner_chunk","ner_chunk_1","ner_chunk_2")). The input columns must be chunk columns.

Example :

...
deid_ner = MedicalNerModel.pretrained("ner_deid_large", "en", "clinical/models") \
            .setInputCols(["sentence", "token", "embeddings"]) \
            .setOutputCol("ner")

ner_converter = NerConverter() \
            .setInputCols(["sentence", "token", "ner"]) \
            .setOutputCol("ner_chunk") \
            .setWhiteList(['DATE', 'AGE', 'NAME', 'PROFESSION', 'ID'])

medical_ner = MedicalNerModel.pretrained("ner_events_clinical", "en", "clinical/models") \
            .setInputCols(["sentence", "token", "embeddings"]) \
            .setOutputCol("ner2")

ner_converter_2 = NerConverter() \
            .setInputCols(["sentence", "token", "ner2"]) \
            .setOutputCol("ner_chunk_2")

ssn_parser = ContextualParserApproach() \
            .setInputCols(["sentence", "token"]) \
            .setOutputCol("entity_ssn") \
            .setJsonPath("../../src/test/resources/ssn.json") \
            .setCaseSensitive(False) \
            .setContextMatch(False)

chunk_merge = ChunkMergeApproach() \
            .setInputCols("entity_ssn","ner_chunk","ner_chunk_2") \
            .setOutputCol("deid_merged_chunk") \
            .setChunkPrecedence("field")      
...

New setBlackList Feature in ChunkMergeApproach

Now we can filter out the entities in the ChunkMergeApproach using a black list .setBlackList(["NAME","ID"]). The entities specified in the blackList will be excluded from the final entity list.

Example :

chunk_merge = ChunkMergeApproach() \
            .setInputCols("entity_ssn","ner_chunk") \
            .setOutputCol("deid_merged_chunk") \
            .setBlackList(["NAME","ID"])

New setBlackList Feature in NerConverterInternal

Now we can filter out the entities in the NerConverterInternal using a black list .setBlackList(["Drug","Treatment"]). The entities specified in the blackList will be excluded from the final entity list.

Example :

ner = MedicalNerModel.pretrained("ner_jsl_slim", "en", "clinical/models")\
        .setInputCols("sentence", "token","embeddings")\
        .setOutputCol("ner")

converter = NerConverterInternal()\
        .setInputCols("sentence","token","ner")\
        .setOutputCol("entities")\
        .setBlackList(["Drug","Treatment"])

New setLabelCasing Feature in MedicalNerModel

Now we can decide if we want to return the tags in upper or lower case with setLabelCasing(). That method convert the I-tags and B-tags in lower or upper case during the inference. The values will be ‘lower’ for lower case and ‘upper’ for upper case.

Example :

...
ner_tagger = MedicalNerModel() \
            .pretrained("ner_clinical", "en", "clinical/models") \
            .setInputCols(["sentences", "tokens", "embeddings"]) \
            .setOutputCol("ner_tags") \
            .setLabelCasing("lower")
...

results = LightPipeline(pipelineModel).annotate("A 28-year-old female with a history of gestational diabetes mellitus diagnosed eight years prior to presentation and subsequent type two diabetes mellitus ")
results["ner_tags"]

Results :

['O', 'O', 'O', 'O', 'O', 'O', 'O', 'B-problem', 'I-problem', 'I-problem', 'O', 'O', 'O', 'O', 'O', 'O', 'O', 'B-problem', 'I-problem', 'I-problem', 'I-problem', 'I-problem']

New Update Models Functionality

We developed a new utility function called UpdateModels that allows you to refresh your cache_pretrained folder without running any annotator or manually checking. It has two methods;

UpdateModels.updateCacheModels() : This method lets you update all the models existing in the cache_pretrained folder. It downloads the latest version of all the models existing in the cache_pretrained.

Example :

# Models in /cache_pretrained
ls ~/cache_pretrained
>> ner_clinical_large_en_3.0.0_2.3_1617206114650/

# Update models in /cache_pretrained
from sparknlp_jsl.updateModels import UpdateModels
UpdateModels.updateCacheModels()

Results :

# Updated models in /cache_pretrained
ls ~/cache_pretrained
>> ner_clinical_large_en_3.0.0_2.3_1617206114650/
   ner_clinical_large_en_3.0.0_3.0_1617206114650/

UpdateModels.updateModels("11/24/2021") : This method lets you download all the new models uploaded to the Models Hub starting from a cut-off date (i.e. the last sync update).

Example :

# Models in /cache_pretrained
ls ~/cache_pretrained
>> ner_clinical_large_en_3.0.0_2.3_1617206114650/
   ner_clinical_large_en_3.0.0_3.0_1617206114650/

# Update models in /cache_pretrained according to date
from sparknlp_jsl.updateModels import UpdateModels
UpdateModels.updateModels("11/24/2021")

Results :

# Updated models in /cache_pretrained
ls ~/cache_pretrained
>>ner_clinical_large_en_3.0.0_2.3_1617206114650/
  ner_clinical_large_en_3.0.0_3.0_1617206114650/
  ner_model_finder_en_3.3.2_2.4_1637761259895/
  sbertresolve_ner_model_finder_en_3.3.2_2.4_1637764208798/

New and Updated Notebooks

We have a new Connect to Annotation Lab via API Notebook you can find how to;
- upload pre-annotations to ALAB
- import a project form ALAB and convert to CoNLL file
- upload tasks without pre-annotations
We have updated Clinical Relation Extraction Notebook by adding a Relation Extraction Model-NER Model-Relation Pairs table that can be used to get the most optimal results when using these models.
