Challenge: a lack of suitable training and evaluation data limits the evaluation of language learning tasks to language proficiency only.
Approach: They develop a marking rubric that covers task adherence with respect to form and content.
Outcome: The proposed model can predict the adherence of learners to written tasks using picture stories.

Analyzing Text Representations by Measuring Task Alignment (2023.acl-short)

Copied to clipboard

Challenge: Recent advances in text classification have shown that pre-trained representations are key for text classification.

Image Description Dataset for Language Learners (2022.lrec-1)

Challenge: Language learners are limited by the number of texts or speech they are asked to answer . automatic assessment of image descriptions requires a system that depends on both the learner's native language and the target language.
Approach: They propose a dataset that consists of images, their descriptions, and assessment annotations . they propose 'automatic error correction' task that encodes multimodal information from a learner sentence with an image and accurately decodes a corrected sentence.
Outcome: The proposed model can revise errors that cannot be revised without an image.

Instruction Induction: From Few Examples to Natural Language Task Descriptions (2023.acl-long)

Copied to clipboard

Challenge: Large language models can perform unseen tasks by conditioning on a few input-output demonstrations, but task inference is implicit and the ability of models to explicitly reason about it remains unexplored.
Approach: They propose an instruction induction challenge in which a model is asked to generate a natural language instruction that fits a set of labeled examples.
Outcome: The proposed model achieves 65.7% of human performance while the original model only reaches 9.8% of human performances.
Automatically Identifying Words That Can Serve as Labels for Few-Shot Text Classification (2020.coling-main)

Copied to clipboard

Challenge: Existing approaches to few-shot text classification require domain expertise and an understanding of the language model's abilities to define the mapping between words and labels.
Approach: They propose a method that converts textual inputs to cloze questions that contain some form of task description and processes them with a pretrained language model to map the predicted words to labels.
Outcome: The proposed approach performs almost as well as hand-crafted label-to-word mappings for a number of tasks with small amounts of training data.

Challenge: Existing research on text classification models with prompts is limited in scale and lacks understanding of how these methods compare to more established methods.
Approach: They compare the performance of large and smaller language models with prompts to achieve state-of-the-art performance in many NLP tasks.
Outcome: The proposed models outperform the more standard approaches in binary, multiclass, and multilabel tasks in a large scale evaluation of 16 text classification datasets.
PiC: A Phrase-in-Context Dataset for Phrase Understanding and Semantic Search (2023.eacl-main)

Copied to clipboard

Challenge: Existing benchmarks for phrase-similarity compare phrases alone (without context) and phrases with context (with or without context).
Approach: They propose to use a dataset of 28K noun phrases accompanied by their contextual Wikipedia pages to train machine phrase embeddings.
Outcome: The proposed dataset improves ranking-models’ accuracy and pushes span selection models near human accuracy, which is 95% Exact Match (EM) on semantic search given a query phrase and a passage.
