architxt 0.1.1

ArchiTXT is a tool for structuring textual data into a valid database model. It is guided by a meta-grammar and uses an iterative process of tree rewriting.

ArchiTXT: Text-to-Database Structuring Tool

ArchiTXT is a robust tool designed to convert unstructured textual data into structured formats that are ready for database storage. It automates the generation of database schemas and creates corresponding data instances, simplifying the integration of text-based information into database systems.

Working with unstructured text can be challenging when you need to store and query it in a structured database. ArchiTXT bridges this gap by transforming raw text into organized, query-friendly structures. By automating both schema generation and data instance creation, it streamlines the entire process of managing textual information in databases.

Installation

To install ArchiTXT, make sure you have Python 3.10+ and pip installed. Then, run:

pip install architxt

For the development version, you can install it directly through GIT using

pip install git+https://github.com/Neplex/ArchiTXT.git

Usage

ArchiTXT is built to work seamlessly with BRAT-annotated corpora that includes pre-labeled named entities. It also requires access to a CoreNLP server, which you can set up using the Docker configuration available in the source repository.

$ architxt --help

To deploy the CoreNLP server using the source repository, you can use Docker Compose with the following command:

docker compose up -d

Development

Setting Up the Development Environment with Poetry

To set up the development environment using Poetry, ensure that you have Poetry installed. You can install it by following the official installation instructions. Once installed, you can set up the development environment by running the following command:

poetry install

Enabling Pre-Commit Hook

This project uses pre-commit for managing Git hooks. It should already be installed by poetry as a dev dependency. To enable the pre-commit hooks locally, run the following command:

poetry run pre-commit install

Once set up, the pre-commit hooks will automatically run every time you make a commit, ensuring code standards are followed.

Meta-Grammar

In ArchiTXT, ANTLR (Another Tool for Language Recognition) is used to generate a parser/lexer for the meta-grammar that verify the database schema's validity. It ensures that the database schema conforms to the expected structure and semantics.

You can view the meta-grammar definition in the metagrammar.g4 file.

To regenerate the parser/lexer for the meta-grammar, run the following command:

$ poetry run antlr4 -Dlanguage=Python3 metagrammar.g4 -o architxt/grammar
