ChunkeyBERT
Overview
ChunkeyBert is a minimal and easy-to-use keyword extraction technique that leverages BERT embeddings for unsupervised
keyphrase extraction from text documents. ChunkeyBert is a modification of the
KeyBERT method to handle documents with
arbitrary length with better results. ChunkeyBERT works by chunking the documents and uses KeyBERT to extract candidate
keywords/keyphrases from all chunks followed by a similarity based selection stage to produce the final keywords for the
entire document. ChunkeyBert can use any document chunking method as long as it can be wrapped in a simple function,
however it can also work without a chunker and process the entire document as a single chunk. ChunkeyBert works with any
configuration of KeyBERT and can handle batches of documents.
Installation
Install from PyPI using pip (preferred method):
pip install chunkey-bert
Experimental results
Very limited experimental results and demonstration of the library on a small number of documents is available at
https://nbviewer.org/github/yaniv-shulman/chunkey-bert/tree/main/src/experiments/.
