PrimeQA: The Prime Repository for State-of-the-Art Multilingual Question Answering Research and Development

1 code implementation23 Jan 2023 Avirup Sil, Jaydeep Sen, Bhavani Iyer, Martin Franz, Kshitij Fadnis, Mihaela Bornea, Sara Rosenthal, Scott McCarley, Rong Zhang, Vishwajeet Kumar, Yulong Li, Md Arafat Sultan, Riyaz Bhat, Radu Florian, Salim Roukos

The field of Question Answering (QA) has made remarkable progress in recent years, thanks to the advent of large pre-trained language models, newer realistic benchmark datasets with leaderboards, and novel algorithms for key components such as retrievers and readers.

GAAMA 2.0: An Integrated System that Answers Boolean and Extractive Questions

no code implementations16 Jun 2022 Scott McCarley, Mihaela Bornea, Sara Rosenthal, Anthony Ferritto, Md Arafat Sultan, Avirup Sil, Radu Florian

Recent machine reading comprehension datasets include extractive and boolean questions but current approaches do not offer integrated support for answering both question types.

Learning to Transpile AMR into SPARQL

no code implementations15 Dec 2021 Mihaela Bornea, Ramon Fernandez Astudillo, Tahira Naseem, Nandana Mihindukulasooriya, Ibrahim Abdelaziz, Pavan Kapanipathi, Radu Florian, Salim Roukos

We propose a transition-based system to transpile Abstract Meaning Representation (AMR) into SPARQL for Knowledge Base Question Answering (KBQA).

Do Answers to Boolean Questions Need Explanations? Yes

no code implementations14 Dec 2021 Sara Rosenthal, Mihaela Bornea, Avirup Sil, Radu Florian, Scott McCarley

Existing datasets that contain boolean questions, such as BoolQ and TYDI QA , provide the user with a YES/NO response to the question.

Are Multilingual BERT models robust? A Case Study on Adversarial Attacks for Multilingual Question Answering

no code implementations15 Apr 2021 Sara Rosenthal, Mihaela Bornea, Avirup Sil

Recent approaches have exploited weaknesses in monolingual question answering (QA) models by adding adversarial statements to the passage.

Multilingual Transfer Learning for QA Using Translation as Data Augmentation

no code implementations10 Dec 2020 Mihaela Bornea, Lin Pan, Sara Rosenthal, Radu Florian, Avirup Sil

Prior work on multilingual question answering has mostly focused on using large multilingual pre-trained language models (LM) to perform zero-shot language-wise learning: train a QA model on English and test on other languages.

Combining Unsupervised Pre-training and Annotator Rationales to Improve Low-shot Text Classification

no code implementations IJCNLP 2019 Oren Melamud, Mihaela Bornea, Ken Barker

In this work, we combine these two approaches to improve low-shot text classification with two novel methods: a simple bag-of-words embedding approach; and a more complex context-aware method, based on the BERT model.

Stacking With Auxiliary Features for Entity Linking in the Medical Domain

no code implementations WS 2017 Nazneen Fatema Rajani, Mihaela Bornea, Ken Barker

In the medical domain, it is common to link text spans to medical concepts in large, curated knowledge repositories such as the Unified Medical Language System.

Scoring Disease-Medication Associations using Advanced NLP, Machine Learning, and Multiple Content Sources

no code implementations WS 2016 D, Bharath ala, Murthy Devarakonda, Mihaela Bornea, Christopher Nielson

In predicting positive associations, the stacked combination significantly outperformed the baseline (a distant semi-supervised method on large medical text), achieving F scores of 0. 75 versus 0. 55 on the pairs seen in the patient records, and F scores of 0. 69 and 0. 35 on unique pairs.
