Using Linguistic Features to Predict the Response Process Complexity Associated with Answering Clinical MCQs

no code implementations EACL (BEA) 2021 Victoria Yaneva, Daniel Jurich, Le An Ha, Peter Baldwin

This study examines the relationship between the linguistic characteristics of a test item and the complexity of the response process required to answer it correctly.

Automated Prediction of Examinee Proficiency from Short-Answer Questions

no code implementations COLING 2020 Le An Ha, Victoria Yaneva, Polina Harik, Ravi Pandian, Amy Morales, Brian Clauser

This paper brings together approaches from the fields of NLP and psychometric measurement to address the problem of predicting examinee proficiency from responses to short-answer questions (SAQs).

Classifying Referential and Non-referential It Using Gaze

1 code implementation EMNLP 2018 Victoria Yaneva, Le An Ha, Richard Evans, Ruslan Mitkov

When processing a text, humans and machines must disambiguate between different uses of the pronoun it, including non-referential, nominal anaphoric or clause anaphoric ones.

A First Dataset for Film Age Appropriateness Investigation

no code implementations LREC 2020 Emad Mohamed, Le An Ha

Film age appropriateness classification is an important problem with a significant societal impact that has so far been out of the interest of Natural Language Processing and Machine Learning researchers.

Predicting Item Survival for Multiple Choice Questions in a High-Stakes Medical Exam

no code implementations LREC 2020 Victoria Yaneva, Le An Ha, Peter Baldwin, Janet Mee

One of the most resource-intensive problems in the educational testing industry relates to ensuring that newly-developed exam questions can adequately distinguish between students of high and low ability.

Automatic Question Answering for Medical MCQs: Can It go Further than Information Retrieval?

no code implementations RANLP 2019 Le An Ha, Victoria Yaneva

We present a novel approach to automatic question answering that does not depend on the performance of an information retrieval (IR) system and does not require that the training data come from the same source as the questions.

A Survey of the Perceived Text Adaptation Needs of Adults with Autism

no code implementations RANLP 2019 Victoria Yaneva, Constantin Orasan, Le An Ha, Natalia Ponomareva

NLP approaches to automatic text adaptation often rely on user-need guidelines which are generic and do not account for the differences between various types of target groups.

Predicting the Difficulty of Multiple Choice Questions in a High-stakes Medical Exam

no code implementations WS 2019 Le An Ha, Victoria Yaneva, Peter Baldwin, Janet Mee

To accomplish this, we extract a large number of linguistic features and embedding types, as well as features quantifying the difficulty of the items for an automatic question-answering system.

Cross-lingual Transfer Learning and Multitask Learning for Capturing Multiword Expressions

no code implementations WS 2019 Shiva Taslimipoor, Omid Rohanian, Le An Ha

Recent developments in deep learning have prompted a surge of interest in the application of multitask and transfer learning to NLP problems.

Bridging the Gap: Attending to Discontinuity in Identification of Multiword Expressions

2 code implementations NAACL 2019 Omid Rohanian, Shiva Taslimipoor, Samaneh Kouchaki, Le An Ha, Ruslan Mitkov

We introduce a new method to tag Multiword Expressions (MWEs) using a linguistically interpretable language-independent deep learning architecture.

Automatic Distractor Suggestion for Multiple-Choice Tests Using Concept Embeddings and Information Retrieval

no code implementations WS 2018 Le An Ha, Victoria Yaneva

We frame the evaluation as a prediction task where we aim to {``}predict{''} the human-produced distractors used in large sets of medical questions, i. e. if a distractor generated by our system is good enough it is likely to feature among the list of distractors produced by the human item-writers.

Using Gaze Data to Predict Multiword Expressions

no code implementations RANLP 2017 Omid Rohanian, Shiva Taslimipoor, Victoria Yaneva, Le An Ha

In recent years gaze data has been increasingly used to improve and evaluate NLP models due to the fact that it carries information about the cognitive processing of linguistic phenomena.
