Usage examples of nlp.load()
The following examples demonstrate how to use nlu’s load api accompanied by the outputs generated by it.
It enables loading any model or pipeline in one line You need to pass one NLU reference to the load method.
You can also pass multiple whitespace separated references.
You can find all NLU references here
Medical Named Entity Recognition (NER)
NLU provided a separate and highly tuned medical NER models for various Healthcare domains.
These medical NER models are trained to extract various medical named entities

Zero-Shot NER
Zero-Shot NER Tutorial Notebook
Based on John Snow Labs Enterprise-NLP ZeroShotNerModel
Zero shot models excel at generalization, meaning that the model can accurately predict entities in very different data sets without the need to fine tune the model or train from scratch for each different domain.
Even though a model trained to solve a specific problem can achieve better accuracy than a zero-shot model in this specific task,
it probably won’t be useful in a different task.
That is where zero-shot models shows its usefulness by being able to achieve good results in various domains.
Usage:
We just need to load the zero-shot NER model and configure a set of entity definitions.
# load zero-shot ner model
enterprise_zero_shot_ner = nlp.load('en.zero_shot.ner_roberta')
# Configure entity definitions
enterprise_zero_shot_ner['zero_shot_ner'].setEntityDefinitions(
{
"PROBLEM": [
"What is the disease?",
"What is his symptom?",
"What is her disease?",
"What is his disease?",
"What is the problem?",
"What does a patient suffer",
"What was the reason that the patient is admitted to the clinic?",
],
"DRUG": [
"Which drug?",
"Which is the drug?",
"What is the drug?",
"Which drug does he use?",
"Which drug does she use?",
"Which drug do I use?",
"Which drug is prescribed for a symptom?",
],
"ADMISSION_DATE": ["When did patient admitted to a clinic?"],
"PATIENT_AGE": [
"How old is the patient?",
"What is the gae of the patient?",
],
}
)
Then we can already use this pipeline to predict labels
# Predict entities
df = enterprise_zero_shot_ner.predict(

"The doctor pescribed Majezik for my severe headache.",

Entity Resolution (for sentences)
Entity Resolution tutorial notebook
Classify each sentence
extracted by a sentence detector
into one of C
resolvable classes.
These classes usually are international disease
, medicine
, or procedure
codes based on ICD standards.

Relation Extraction
Relation Extraction tutorial notebook
Classify for pairs of entities what kind of relation
exists between them.
It classifies for every named entity
, which type of relationship
exists to the other entities
.
More precisely, internally the relation extractor classifies every pair of entities
into one out of C
potential relation classes.
There could be no relation between a pair of entities
or there could a relation, which is specified by ` the predicted relation label` .
You can specify predict(data,output_level='relation
to have one row per classified relation in your resulting dataframe.
Depending on what models are loaded in your pipe, NLU infers output_level=relation
automatically and configures to that, unless specified otherwise.

Drug Normalizer
Drug Normalizer tutorial notebook
Normalize raw text from clinical documents, e.g. scraped web pages or xml document. Removes all dirty characters from text following one or more input regex patterns. Can apply non wanted character removal which a specific policy. Can apply lower case normalization.
Parameters are
- lowercase: whether to convert strings to lowercase. Default is False.
policy
: rule to remove patterns from text. Valid policy values are:all
abbreviations
,dosages
Defaults isall
.abbreviation
policy used to expend common drugs abbreviations,dosages
policy used to convert drugs dosages and values to the standard form (see examples bellow).

Rule based NER with Context Matcher
Rule based NER with context matching tutorial notebook
Define a rule based NER algorithm by providing Regex Patterns and resolution mappings.
The confidence value is computed using a heuristic approach based on how many matches it has.
A dictionary can be provided with setDictionary to map extracted entities to a unified representation. The first column of the dictionary file should be the representation with following columns the possible matches.

Two weeks prior to presentation , she was treated with a five-day course of amoxicillin for a respiratory tract infection . She was on metformin , glipizide , and dapagliflozin for T2DM and atorvastatin and gemfibrozil for HTG . She had been on dapagliflozin for six months at the time of presentation . Physical examination on presentation was significant for dry oral mucosa ; significantly , her abdominal examination was benign with no tenderness , guarding , or rigidity . Pertinent laboratory findings on admission were : serum glucose 111 mg/dl , bicarbonate 18 mmol/l , anion gap 20 , creatinine 0.4 mg/dL , triglycerides 508 mg/dL , total cholesterol 122 mg/dL , glycated hemoglobin ( HbA1c ) 10% , and venous pH 7.27 . Serum lipase was normal at 43 U/L . Serum acetone levels could not be assessed as blood samples kept hemolyzing due to significant lipemia . The patient was initially admitted for starvation ketosis , as she reported poor oral intake for three days prior to admission . However , serum chemistry obtained six hours after presentation revealed her glucose was 186 mg/dL , the anion gap was still elevated at 21 , serum bicarbonate was 16 mmol/L , triglyceride level peaked at 2050 mg/dL , and lipase was 52 U/L . β-hydroxybutyrate level was obtained and found to be elevated at 5.29 mmol/L - the original sample was centrifuged and the chylomicron layer removed prior to analysis due to interference from turbidity caused by lipemia again . The patient was treated with an insulin drip for euDKA and HTG with a reduction in the anion gap to 13 and triglycerides to 1400 mg/dL , within 24 hours . Twenty days ago. Her euDKA was thought to be precipitated by her respiratory tract infection in the setting of SGLT2 inhibitor use . At birth the typical boy is growing slightly faster than the typical girl, but the velocities become equal at about seven months, and then the girl grows faster until four years. From then until adolescence no differences in velocity can be detected. 21-02-2020 21/04/2020 """

Automatically Authorize Google Colab via JSON file
By default, nlu checks /content/spark_nlp_for_healthcare.json
on google colabe enviroments for a spark_nlp_for_healthcare.json
file that you recieve via E-mail from us.
If you upload the spark_nlp_for_healthcare.json
file to the standard colab directory, nlp.load()
will automatically find it and authorize your enviroment.
Authorize anywhere via providing via JSON file
You can specify the location of your spark_nlp_for_healthcare.json
like this :
path = '/path/to/spark_nlp_for_healthcare.json'
nlp.auth(path).load('licensed_model').predict(data)
