Welcome to IEPY’s documentation!¶
IEPY is an open source tool for Information Extraction focused on Relation Extraction.
To give an example of Relation Extraction, if we are trying to find a birth date in:
“John von Neumann (December 28, 1903 – February 8, 1957) was a Hungarian and American pure and applied mathematician, physicist, inventor and polymath.”
then IEPY’s task is to identify “
John von Neumann” and
December 28, 1903” as the subject and object entities of the “
was born in”
- It’s aimed at:
An active learning relation extraction tool pre-configured with convenient defaults.
A rule based relation extraction tool for cases where the documents are semi-structured or high precision is required.
- A web-based user interface that:
- Allows layman users to control some aspects of IEPY.
- Allows decentralization of human input.
A shallow entity ontology with coreference resolution via Stanford CoreNLP
An easily hack-able active learning core, ideal for scientist wanting to experiment with new algorithms.
