SentenceTransformer

This is a sentence-transformers model trained. 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.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("Jrinky/jina3")
# Run inference
sentences = [
    'What challenges does Mayor Hundred face in leading New York as depicted in March to War',
    'His heroics convinced the citizens of New York to elect him mayor, and March to War opens with Mayor Hundred dealing with unrest in the city. Political cartoons display him as a caped superhero unable to handle the daily needs of the city, and a protest against the war in Iraq has it divided.',
    "Bring your sewing machine - scissors - material - pattern (if you already have one that you want to work on) - have a project that you need assistance with - just want to spend the day with your fellow Caerthen's in a day of sewing and socializing? Come on out!",
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]

The previous instalment can be viewed here.`

`What significant role did the character Raven portray in early cinema`	He played cynical tough guys in modern films, but then branched into westerns where for the most part he was the gallant hero. In fact the ultimate gallant white knight hero in Shane. His part as Raven is a difficult one, yet he pulls it off. He's a cold blooded contract killer, one of the earliest ever portrayed as a film protagonist. Yet he's human and you see flashes of it, his concern for cats. As a cat lover, I can sure identify with that. Raven is also one of the earliest characters in cinema who talks about child abuse making him what he is. Groundbreaking when you think about it. Next to Ladd, the biggest kudos have to go to Laird Cregar, borrowed from 20th Century Fox to play Willard Gates. Gates is a top company executive with Marshall's firm which is a defense contractor which is why the Senate is interested in him. He's basically a jerk who thinks he's so clever. Veronica Lake gets to him real easy because of his weakness for the nightclub scene.
`What are the key features and characteristics of the Majestic Pure Dead Sea Mud Mask`	At the same time, it can be used all over your body, not just face. This way, you can clear any part of your skin from its impurities. An additional feature that caught our eyes immediately was the beautifully designed packaging that makes this affordable product look high-end. The combination of grey, black, and blue colors will easily make it stand out in any beauty shop. - Good for sensitive and dry skin - Affordable price - Treats many different skin conditions - Not good for oily skin - Can feel a bit oily Majestic Pure Dead Sea Mud Mask Review Majestic Pure is a well-known brand among the beauty and skincare community. They make affordable, natural products and are oftentimes among the celebrity favorites.
`What benefits does this product provide for the skin`	`This will provide you with softer skin that glows. At the same time, it will help you deal with your clogged pores and provide you the necessary daily acne treatment.`
