DataFog Instructor SDK

DataFog Instructor is a Python SDK for named entity recognition (NER) using Ollama as the LLM backend. It provides an easy-to-use interface for detecting and classifying entities in text.

Installation

To install the DataFog Instructor SDK, you can use pip:

pip install datafog-instructor

For development purposes, including testing and documentation tools:

pip install datafog-instructor[dev,docs]

Quick Start

Here's a simple example to get you started with DataFog Instructor:

from datafog_instructor import DataFog

# Initialize DataFog with default settings
datafog = DataFog()

# Detect entities in text
text = "Cisco acquires Hess for $20 billion"
result = datafog.detect_entities(text)

# Print results
for entity in result.entities:
    print(f"Text: {entity.text}, Type: {entity.type.value}")

Configuration

You can customize the DataFog instance using environment variables:

• DATAFOG_LLM_BACKEND: Currently only supports "ollama"
• DATAFOG_LLM_ENDPOINT: The host URL for the Ollama service (default: "http://localhost:11434")
• DATAFOG_LLM_MODEL: The model to use for entity detection (default: "phi3")

Example with custom settings:

import os
os.environ['DATAFOG_LLM_ENDPOINT'] = 'http://custom-ollama-host:11434'
os.environ['DATAFOG_LLM_MODEL'] = 'custom-model'

from datafog_instructor import DataFog

datafog = DataFog()

Features

Detect Entities

Use the detect_entities method to identify and classify named entities in a given text:

text = "Apple Inc. reported $100 billion in revenue for Q4 2023"
result = datafog.detect_entities(text)

for entity in result.entities:
    print(f"Text: {entity.text}, Type: {entity.type.value}")

Manage Entity Types

You can add or remove entity types dynamically:

# Add a new entity type
datafog.add_entity_type("CUSTOM", "Custom Entity")

# Remove an entity type
datafog.remove_entity_type("CUSTOM")

# Get all entity types
entity_types = datafog.get_entity_types()
print(entity_types)

Default Entity Types

The SDK comes with an expanded list of predefined entity types, including:

• Organization Information: ORG, PERSON, TRANSACTION_TYPE, DEAL_STRUCTURE, FINANCIAL_INFO, PRODUCT, LOCATION, DATE, INDUSTRY, ROLE, REGULATORY, SENSITIVE_INFO, CONTACT, ID, STRATEGY, COMPANY, MONEY
• Personal Information: EMAIL, PHONE, SSN, CREDIT_CARD, IP_ADDRESS, URL, AGE, NATIONALITY, JOB_TITLE, EDUCATION
• Location Information: ADDRESS, CITY, STATE, ZIP, COUNTRY, REGION

Error Handling

The SDK includes error handling for various scenarios. If there's an issue with processing the response or an unexpected response format, it will raise a ValueError with details about the error.

Development and Testing

For development purposes, you can install additional dependencies:

pip install datafog-instructor[dev]

This includes tools like pytest, black, flake8, and mypy for testing and code quality.

Documentation

To build the documentation locally:

pip install datafog-instructor[docs]
cd docs
make html

The documentation will be available in the docs/_build/html directory.
