FormLM: Recommending Creation Ideas for Online Forms by Modelling Semantic and Structural Information

no code implementations10 Nov 2022 Yijia Shao, Mengyu Zhou, Yifan Zhong, Tao Wu, Hongwei Han, Shi Han, Gideon Huang, Dongmei Zhang

To assist form designers, in this work we present FormLM to model online forms (by enhancing pre-trained language model with form structural information) and recommend form creation ideas (including question / options recommendations and block type suggestion).

MRCLens: an MRC Dataset Bias Detection Toolkit

no code implementations18 Jul 2022 Yifan Zhong, Haohan Wang, Eric P. Xing

Many recent neural models have shown remarkable empirical results in Machine Reading Comprehension, but evidence suggests sometimes the models take advantage of dataset biases to predict and fail to generalize on out-of-sample data.

Automatically Identifying Language Family from Acoustic Examples in Low Resource Scenarios

1 code implementation1 Dec 2020 Peter Wu, Yifan Zhong, Alan W Black

Existing multilingual speech NLP works focus on a relatively small subset of languages, and thus current linguistic understanding of languages predominantly stems from classical approaches.
