IBM MNLP IE at CASE 2021 Task 2: NLI Reranking for Zero-Shot Text Classification

no code implementations ACL (CASE) 2021 Ken Barker, Parul Awasthy, Jian Ni, Radu Florian

The NLI reranker uses a textual representation of target types that allows it to score the strength with which a type is implied by a text, without requiring training data for the types.

Distilling Event Sequence Knowledge From Large Language Models

no code implementations14 Jan 2024 Somin Wadhwa, Oktie Hassanzadeh, Debarun Bhattacharjya, Ken Barker, Jian Ni

In this work, we explore the use of Large Language Models (LLMs) to generate event sequences that can effectively be used for probabilistic event model construction.

An Evaluation Framework for Mapping News Headlines to Event Classes in a Knowledge Graph

1 code implementation4 Dec 2023 Steve Fonin Mbouadeu, Martin Lorenzo, Ken Barker, Oktie Hassanzadeh

In this paper, we present a methodology for creating a benchmark dataset of news headlines mapped to event classes in Wikidata, and resources for the evaluation of methods that perform the mapping.

Leveraging Medical Literature for Section Prediction in Electronic Health Records

no code implementations IJCNLP 2019 Sara Rosenthal, Ken Barker, Zhicheng Liang

We propose using sections from medical literature (e. g., textbooks, journals, web content) that contain content similar to that found in EHR sections.

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.
