Overview

Overview#

pyJedAI is a python framework, aiming to offer experts and novice users, robust and fast solutions for multiple types of Entity Resolution problems. It is builded using state-of-the-art python frameworks. pyJedAI constitutes the sole open-source Link Discovery tool that is capable of exploiting the latest breakthroughs in Deep Learning and NLP techniques, which are publicly available through the Python data science ecosystem. This applies to both blocking and matching, thus ensuring high time efficiency, high scalability as well as high effectiveness, without requiring any labelled instances from the user.

Key-Features#

  • Input data-type independent. Both structured and semi-structured data can be processed.

  • Various implemented algorithms.

  • Easy-to-use.

  • Utilizes some of the famous and cutting-edge machine learning packages.

  • Offers supervised and un-supervised ML techniques.

Install#

Warning

We are currently experiencing issues with pypi installation due to a problem with the py-stringmatching dependency. We are actively working on resolving it! A temporary solution is to first install: pip install 'numpy>=1.7.0,<2.0' and then pip install pyjedai.

pyJedAI has been tested in Windows and Linux OS.

Basic requirements

  • Python version greater or equal to 3.8.

  • For Windows, Microsoft Visual C++ 14.0 is required. Download it from Microsoft Official site.

PyPI

Install the latest version of pyjedai:

pip install pyjedai

Java - Web Application#

pyJedAI

For Java users checkout the initial JedAI. There you can find Java based code and a Web Application for interactive creation of ER workflows.

JedAI constitutes an open source, high scalability toolkit that offers out-of-the-box solutions for any data integration task, e.g., Record Linkage, Entity Resolution and Link Discovery. At its core lies a set of domain-independent, state-of-the-art techniques that apply to both RDF and relational data.
