Chinese Financial Sentiment Analysis Model (Crypto Focus)
中文金融情感分析模型(加密货币领域)
模型描述 | Model Description
本模型基于 yiyanghkust/finbert-tone-chinese 经过多轮迭代微调,专门用于分析中文加密货币相关新闻和社交媒体内容的情感倾向。模型可以识别三种情感类别:正面(Positive)、中性(Neutral)和负面(Negative)。
训练数据经过 Claude AI 逐条人工审阅、纠正标注错误,确保数据质量。
This model is iteratively fine-tuned from yiyanghkust/finbert-tone-chinese, specifically designed for sentiment analysis of Chinese cryptocurrency-related news and social media content. It classifies text into three sentiment categories: Positive, Neutral, and Negative.
Training data is manually reviewed and corrected entry-by-entry by Claude AI to ensure annotation quality.

使用方法 | Usage
快速开始 | Quick Start
from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch
# 加载模型和分词器 | Load model and tokenizer
model_name = "LocalOptimum/chinese-crypto-sentiment"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)
# 分析文本 | Analyze text
text = "比特币突破10万美元创历史新高"
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=128)
# 预测 | Predict
with torch.no_grad():
outputs = model(**inputs)
predictions = torch.nn.functional.softmax(outputs.logits, dim=-1)
predicted_class = torch.argmax(predictions, dim=-1).item()
# 结果映射 | Result mapping
labels = ['positive', 'neutral', 'negative']
sentiment = labels[predicted_class]
confidence = predictions[0][predicted_class].item()
print(f"情感: {sentiment}")
print(f"置信度: {confidence:.4f}")
批量处理 | Batch Processing
texts = [
"币安获得阿布扎比监管授权",
"以太坊完成Fusaka升级",
"某交易所遭攻击损失100万美元"
]
inputs = tokenizer(texts, return_tensors="pt", truncation=True,
max_length=128, padding=True)
with torch.no_grad():
outputs = model(**inputs)
predictions = torch.nn.functional.softmax(outputs.logits, dim=-1)
predicted_classes = torch.argmax(predictions, dim=-1)
labels = ['positive', 'neutral', 'negative']
for text, pred in zip(texts, predicted_classes):
print(f"{text} -> {labels[pred]}")

适用场景 | Use Cases
- ✅ 加密货币新闻情感分析
- ✅ 社交媒体舆情监控
- ✅ 金融市场情绪指标
- ✅ 实时新闻情感跟踪
- ✅ 投资决策辅助参考
核心标注原则 | Annotation Principles
- 加密货币是风险资产(类似美股),不是避险资产(类似黄金)
- 战争、地缘冲突、关税 → negative(利空风险资产)
- 平台上线新币种/功能 → neutral(常规运营,非利好)
- 个人观点/分析师预测 → neutral(主观意见)
- 明确利好(ETF通过、大额买入、政策支持)→ positive
- 明确利空(清算、暴跌、诈骗、监管打压)→ negative
局限性 | Limitations
- ⚠️ 主要针对加密货币领域的金融新闻,其他金融领域可能表现不佳
- ⚠️ 短文本(少于10字)的分析准确率可能下降
- ⚠️ 仅支持简体中文
- ⚠️ 模型不能替代人工判断,仅供参考
