EntityAnonymization-3B-V0.9

EntityAnonymization identifies entities in texts and replaces them with randomised versions.

In a first pass, the entities are recognised and a dictionary with similar but randomised variants is created.

In a second run, the original text and the dictionary are provided and the paraphrased variant is generated.

The two-step approach allows the dictionary to be cached and converted back to an anonymised text that has been further processed.

Usage and Specific Capabilities

Text Length Limitation

The model is optimized to analyze texts containing up to 2048 tokens. If your text exceeds this limit, we recommend splitting it into smaller chunks, each containing no more than 2048 tokens. Each chunk can then be processed separately.

Supported Languages

Bulgarian, Chinese, Czech, Dutch, English, Estonian, Finnish, French, German, Greek, Indonesian, Italian, Japanese, Korean, Lithuanian, Norwegian, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, Swedish, Turkish

Use Cases

Entity Resampling and Anonymization

Introducing a cutting-edge model tailored to the task of extracting entities from sensitive text and anonymizing it. This model specializes in identifying and safeguarding confidential information, ensuring organizations' compliance with stringent data privacy regulations and minimizing the potential for inadvertent disclosure of classified data and trade secrets.

Example Usage

!pip install sentencepiece
!pip install transformers

import torch
import json
import re
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("metricspace/EntityAnonymization-3B-V0.9")
model = AutoModelForCausalLM.from_pretrained("metricspace/EntityAnonymization-3B-V0.9", torch_dtype=torch.bfloat16)
model.to("cuda:0")

def extract_last_assistant_response(input_text):
    # Find the occurrence of "ASSISTANT:" in the input text
    match = re.search(r'ASSISTANT:', input_text)

    # Get the index where the last "ASSISTANT:" ends
    start_index = match.end()
    response = input_text[start_index:].strip()
    return response

Subject: Official Warning – Substance Misuse Policy Violation

Dear Mr. Edward Martin,

We hope this letter finds you well. This letter serves as an official warning in regards to an incident that occurred on October 25, 2023, in which signs of drug misuse were reported. This alleged conduct is highly alarming and contrary to our company’s policies and guidelines.

The incident detailed allegations of unusual behavior indicative of possible substance abuse. Colleagues reported that you appeared disoriented and were found in the restroom for an extended period. Additionally, unidentified pills were discovered near your workspace.

Our company is committed to providing a safe and non-detrimental work environment for all its workforce. This commitment is compromised when any type of drug misuse occurs. We draw your attention to our Employee Handbook, specifically 'Section 5: Substance Misuse', that states any illegal drug use, substance misuse or distribution thereof is strictly prohibited and could be subject to severe disciplinary action, including termination.

This is an official warning that such behavior misaligns with our workplace norms and cannot be tolerated. Another incident like this or similar breach of company guidelines may lead to further disciplinary action, up to and including termination of employment.

Please note that this is not an assumption of your guilt but an assertion to remain vigilant against any practices that could harm you or the workplace environment. We encourage you to utilize our Personal Assistance Program (PAP) as a tool for counseling and support, if needed.

We believe in your potential to rectify this situation and to maintain the high standards we are all accustomed to in our organization.

Should you need assistance or if you wish to discuss this matter further, please feel free to reach out to me. We appreciate your immediate attention to this important issue.

Yours sincerely,

Mrs. Charlotte Johnson
