This is a sentence-transformers model finetuned from intfloat/multilingual-e5-large. It maps sentences & paragraphs to a 1024-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    'query: iRobot 【美國機器人】Roomba 105 Combo 掃拖機器人 送 Roomba Combo Essentail 掃拖機器人',
    'passage: 【iRobot】特談 Roomba Combo Essential 掃拖機器人(18倍吸力/超薄8公分/3段吸力水量/電力110分)',
    'passage: 【CHANEL 香奈兒】ALLURE男性運動淡香水(50ml-國際航空版)',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.4818, 0.0740],
#         [0.4818, 1.0000, 0.1612],
#         [0.0740, 0.1612, 1.0000]])
