Overview

This project enables the efficient extraction of structured data from unstructured text using large language models (LLMs). It provides a flexible configuration system and supports a variety of tasks.

Tool Workflow

---

Setup Environment

To set up the environment, run the following commands:

conda create --name=llm_extractinator python=3.12
conda activate llm_extractinator

pip install -e .

Setting Up Task Configuration

Create a JSON file in the tasks folder for each task, following the naming convention:

TaskXXX_taskname.json

Where XXX is a 3-digit number, and taskname is a brief descriptor of the task.

The JSON file should always include the following fields:

• Task: The name of the task.
• Type: The type of task.
• Description: A detailed description of the task.
• Data_Path: The filename of the data file in the data folder.
• Input_Field: The column name containing the text data.
• Parser_Format: The JSON format you want the output to be in. See Task999_example.json for an example.

The following fields are only mandatory if you want to have the model automatically generate examples:

• Example_Path: The path to data used for creating examples (only required if num_examples > 0 when running the model).
• Label_Field: The column name containing the ground truth labels (only required if num_examples > 0).

Input Flags for extractinate

The following input flags can be used to configure the behavior of the extractinate script:

Flag	Type	Default Value	Description
--task_id	int	Required	Task ID to generate examples for.
--model_name	str	"mistral-nemo"	Name of the model to use for prediction tasks. See https://ollama.com/search for the options.
--num_examples	int	0	Number of examples to generate for each task.
--n_runs	int	5	Number of runs to perform.
--temperature	float	0.3	Temperature for text generation.
--max_context_len	int	8192	Maximum context length for input text.
--num_predict	int	1024	Maximum number of tokens to predict.
--run_name	Path	"run"	Name of the run for logging purposes.
--output_dir	Path	<project_root>/output	Path to the directory for output files.
--task_dir	Path	<project_root>/tasks	Path to the directory containing task configuration files.
--log_dir	Path	<project_root>/output	Path to the directory for log files.
--data_dir	Path	<project_root>/data	Path to the directory containing input data.
--chunk_size	int	None	Number of examples to generate in a single chunk. When None, use dataset size as chunksize.
--translate	bool	False	Translate the generated examples to English.

Example Task.json

Below is an example configuration file for a task:

{
    "Task": "Text Summarization",
    "Type": "Summarization",
    "Description": "Generate summaries for long-form text documents.",
    "Data_Path": "data/documents.csv",
    "Example_Path": "data/summaries_examples.csv",
    "Input_Field": "text",
    "Label_Field": "summary",
    "Parser_Format": {
        "summary": "string"
    }
}

Running the Extractor

To run the data extraction process, use the following command:

extractinate --task_id 001 --model_name "mistral-nemo" --num_examples 0 --max_context_len 8192 --num_predict 8192 --translate

Customize the flags based on your task requirements.

---

Output

The output will be saved in the specified --output_dir. Ensure that the directory structure and paths specified in the Task.json file match your project's organization.

For further details, check the logs in the directory specified by --log_dir.
