Overview
jina-colbert-reranker-v1-en is an open-source English ColBERT-based reranking model.
ColBERT (Contextualized Late Interaction over BERT) leverages the deep language understanding of BERT while introducing a novel interaction mechanism. This mechanism, known as late interaction, allows for efficient and precise retrieval by processing queries and documents separately until the final stages of the retrieval process.
Use-cases: Vector search, retrieval augmented generation.
Highlights
- Jina-colbert-reranker-v1-en's main advancement is its backbone, jina-bert-v2-base-en, which enables processing of significantly longer contexts (up to 8192 tokens) compared to the original ColBERT that uses bert-base-uncased. This capability is crucial for handling query and documents with extensive content, providing more detailed and contextual search results.
- Use-cases: Fine-grained vector search, retrieval augmented generation.
