SWAHILI QUESTION - ANSWER MODEL
This is the bert-base-multilingual-cased model, fine-tuned using the KenyaCorpus dataset. It's been trained on question-answer pairs, including unanswerable questions, for the task of Question Answering in Swahili Language.
Question answering (QA) is a computer science discipline within the fields of information retrieval and NLP that help in the development of systems in such a way that, given a question in natural language, can extract relevant information from provided data and present it in the form of natural language answers.
Overview
Language model used: bert-base-multilingual-cased
Language: Kiswahili
Downstream-task: Extractive Swahili QA
Training data: KenyaCorpus
Eval data: KenyaCorpus
Code: See an example QA pipeline on Haystack
Infrastructure: AWS NVIDIA A100 Tensor Core GPU

Usage
In Haystack
Haystack is an NLP framework by deepset. You can use this model in a Haystack pipeline to do question answering at scale (over many documents). To load the model in Haystack:
reader = FARMReader(model_name_or_path="innocent-charles/Swahili-question-answer-latest-cased")
# or
reader = TransformersReader(model_name_or_path="innocent-charles/Swahili-question-answer-latest-cased",tokenizer="innocent-charles/Swahili-question-answer-latest-cased")
For a complete example of Swahili-question-answer-latest-cased being used for Swahili Question Answering, check out the Tutorials in Haystack Documentation
In Transformers
from transformers import AutoModelForQuestionAnswering, AutoTokenizer, pipeline
model_name = "innocent-charles/Swahili-question-answer-latest-cased"
# a) Get predictions
nlp = pipeline('question-answering', model=model_name, tokenizer=model_name)
QA_input = {
'question': 'Asubuhi ilitupata pambajioi pa hospitali gani?',
'context': 'Asubuhi hiyo ilitupata pambajioni pa hospitali ya Uguzwa.'
}
res = nlp(QA_input)
# b) Load model & tokenizer
model = AutoModelForQuestionAnswering.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
