Training Data for Text Embedding Models

This repository contains training files to train text embedding models, e.g. using sentence-transformers.

Data Format

All files are in a jsonl.gz format: Each line contains a JSON-object that represent one training example.

The JSON objects can come in different formats:

  • Pairs: ["text1", "text2"] - This is a positive pair that should be close in vector space.
  • Triplets: ["anchor", "positive", "negative"] - This is a triplet: The positive text should be close to the anchor, while the negative text should be distant to the anchor.
  • Sets: {"set": ["text1", "text2", ...]} A set of texts describing the same thing, e.g. different paraphrases of the same question, different captions for the same image. Any combination of the elements is considered as a positive pair.
  • Query-Pairs: {"query": "text", "pos": ["text1", "text2", ...]} A query together with a set of positive texts. Can be formed to a pair ["query", "positive"] by randomly selecting a text from pos.
  • Query-Triplets: {"query": "text", "pos": ["text1", "text2", ...], "neg": ["text1", "text2", ...]} A query together with a set of positive texts and negative texts. Can be formed to a triplet ["query", "positive", "negative"] by randomly selecting a text from pos and neg.

Available Datasets

Note: I'm currently in the process to upload the files. Please check again next week to get the full list of datasets

We measure the performance for each training dataset by training the nreimers/MiniLM-L6-H384-uncased model on it with MultipleNegativesRankingLoss, a batch size of 256, for 2000 training steps. The performance is then averaged across 14 sentence embedding benchmark datasets from diverse domains (Reddit, Twitter, News, Publications, E-Mails, ...).
