Formatclassifier NoURL

🚀 WebOrganizer/FormatClassifier-NoURL

The FormatClassifier-NoURL is a model that organizes web content into 24 categories based on web - page text, without relying on URL information.

[Paper] [Website] [GitHub]

The FormatClassifier-NoURL organizes web content into 24 categories based on the text contents of web pages (without using URL information). The model is a gte-base-en-v1.5 with 140M parameters fine - tuned on the following training data:

1. WebOrganizer/FormatAnnotations-Llama-3.1-8B: 1M documents annotated by Llama-3.1-8B (first - stage training)
2. WebOrganizer/FormatAnnotations-Llama-3.1-405B-FP8: 100K documents annotated by Llama-3.1-405B-FP8 (second - stage training)

💻 Usage Examples

Basic Usage

from transformers import AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("WebOrganizer/FormatClassifier-NoURL")
model = AutoModelForSequenceClassification.from_pretrained(
    "WebOrganizer/FormatClassifier-NoURL",
    trust_remote_code=True,
    use_memory_efficient_attention=False)

web_page = """How to make a good sandwich? [Click here to read article]"""

inputs = tokenizer([web_page], return_tensors="pt")
outputs = model(**inputs)

probs = outputs.logits.softmax(dim=-1)
print(probs.argmax(dim=-1))
# -> 6 ("Truncated" format, which covers incomplete content)

Advanced Usage

You can convert the logits of the model with a softmax to obtain a probability distribution over the following 24 categories (in order of labels, also see id2label and label2id in the model config):

Efficient Inference

⚠️ Important Note

Using the efficient gte - base - en - v1.5 implementation requires installing xformers (see more here).
