The GeoEmbedding model is a geoscience-specific text embedding model built upon a high-performance large language model and fine-tuned on both general-purpose and in-domain geoscientific datasets. It produces accurate, context-aware vector representations of geoscientific texts, forming the backbone of vector-based retrieval in the RAG pipeline.

Quickstart

To load the GeoEmbedding model with Transformer, use the following snippet:

python

import numpy as np
from sentence_transformers import SentenceTransformer

task_description = 'Given a web search query, retrieve relevant passages that answer the query'
def get_detailed_instruct(task_description: str, query: str) -> str:
    return f'Instruct: {task_description}\nQuery: {query}'

model_name_or_path = 'GeoGPT/GeoEmbedding'

model = SentenceTransformer(model_name_or_path, device="cuda", trust_remote_code=True)

queries = [
    "What is the main cause of earthquakes?",
    "How do sedimentary rocks form?",
]

passages = [
    "Earthquakes occur due to the sudden release of energy in the Earth's crust, often caused by tectonic plate movements along fault lines.",
    "Sedimentary rocks form through the deposition and compaction of mineral and organic particles over time, typically in water bodies.",
]

queries = [get_detailed_instruct(task_description, query) for query in queries]

q_vecs = model.encode(queries, normalize_embeddings=True)
p_vecs = model.encode(passages, normalize_embeddings=True)

print(np.dot(q_vecs, p_vecs.T)) 
#[[0.6369  0.2092 ]
# [0.2499  0.8411 ]]
