textual-haystack 0.1.0

Haystack integration for Tonic Textual PII detection, transformation, and entity extraction

textual-haystack

PII detection, transformation, and entity extraction components for Haystack, powered by Tonic Textual.

Detect sensitive data in documents, extract the raw entities for auditing or custom logic, or synthesize and tokenize PII before ingestion. Drop these components into any Haystack pipeline.

Installation

pip install textual-haystack

Components

Component	Purpose
TonicTextualEntityExtractor	Extract PII entities with type, value, location, and confidence score
TonicTextualDocumentCleaner	Synthesize or tokenize PII in document content

Quick start

export TONIC_TEXTUAL_API_KEY="your-api-key"

Entity extraction

from haystack.dataclasses import Document
from haystack_integrations.components.tonic_textual import (
    TonicTextualEntityExtractor,
)

extractor = TonicTextualEntityExtractor()
result = extractor.run(
    documents=[Document(content="My name is John Smith and my email is [e-mail]")]
)

for entity in TonicTextualEntityExtractor.get_stored_annotations(result["documents"][0]):
    print(f"{entity.entity}: {entity.text} (confidence: {entity.score:.2f})")
# NAME_GIVEN: John (confidence: 0.90)
# NAME_FAMILY: Smith (confidence: 0.90)
# EMAIL_ADDRESS: [e-mail] (confidence: 0.95)

Document cleaning

from haystack.dataclasses import Document
from haystack_integrations.components.tonic_textual import (
    TonicTextualDocumentCleaner,
)

# Synthesize PII with realistic fakes
cleaner = TonicTextualDocumentCleaner(generator_default="Synthesis")
result = cleaner.run(
    documents=[Document(content="Contact John Smith at [e-mail]")]
)
print(result["documents"][0].content)
# "Contact Maria Chen at [e-mail]"

Per-entity control — mix synthesis and tokenization per PII type:

cleaner = TonicTextualDocumentCleaner(
    generator_default="Off",
    generator_config={
        "NAME_GIVEN": "Synthesis",
        "NAME_FAMILY": "Synthesis",
        "EMAIL_ADDRESS": "Redaction",
    },
)

In a pipeline

from haystack import Pipeline
from haystack.dataclasses import Document
from haystack_integrations.components.tonic_textual import (
    TonicTextualDocumentCleaner,
    TonicTextualEntityExtractor,
)

pipeline = Pipeline()
pipeline.add_component("cleaner", TonicTextualDocumentCleaner(generator_default="Synthesis"))
pipeline.add_component("extractor", TonicTextualEntityExtractor())
pipeline.connect("cleaner", "extractor")

result = pipeline.run({
    "cleaner": {
        "documents": [
            Document(content="Contact Jane Doe at [e-mail]"),
        ]
    }
})

Configuration

Self-hosted deployment:

extractor = TonicTextualEntityExtractor(
    base_url="https://textual.your-company.com"
)

Explicit API key:

from haystack.utils.auth import Secret

extractor = TonicTextualEntityExtractor(
    api_key=Secret.from_token("your-api-key")
)
