Model Card for task-llm

This model supports abstractive QA tasks. Given a set of passages and a question, it tries to generate a comprehensive answer by reading the passages. In other words, the model does the generation part of retrieval augmented generation (RAG).

Model Details

This model was intended to be a T5 style multi task model trained with Bart to leverage the larger context length and better performance. At the moment, the only task supported by this model is abstractive qa

Uses

This model supports abstractive QA tasks. Given a set of passages and a question, it tries to generate a comprehensive answer by reading the passages.

Bias, Risks, and Limitations

This model is trained with a very simple dataset and will need further fine tuning for your use cases.

Recommendations

Fine tune the model with your own data.

How to Get Started with the Model

Use the following prompt: prompt = f"###Task: abstractive_qa \n###Question: {question} \n###Passages:{passage}"

where question is your query and passage is a concatenated set of passages that needs to be considered for answering a question.

Use the code below to get started with the model:

To run this code with nlm-model-service, use the following code:

pip install nlm-utils

qa_sum_client_bart = ClassificationClient(
    model="bart",
    task="qa_sum",
    url=v100Url,
    retry=1,
)
# nlm-model-service suppports batch invocation and you can send multiple question/passage pairs at a time.
questions = ["what are the adverse reactions of Dimethylsulfoxide"]
sentences = ["Dimethylsulfoxide Adverse reactions Garlic taste in mouth, dry skin, erythema and pruritis (2), urine discoloration, halitosis, agitation, hypotension, sedation and dizziness (13) have been reported following use of DMSO. Dimethylsulfoxide Adverse reactions: malaria and loose motion."]
qa_sum_client_bart(questions, sentences)
