Discourse Analysis via Questions and Answers: Parsing Dependency Structures of Questions Under Discussion

ACL 2023findings

Automatic discourse processing is bottlenecked by data: current discourse formalisms pose highly demanding annotation tasks involving large taxonomies of discourse relations, making them inaccessible to lay annotators. This work instead adopts the linguistic framework of Questions Under Discussion (…

Discourse Comprehension: A Question Answering Framework to Represent Sentence Connections

EMNLP 2022main

While there has been substantial progress in text comprehension through simple factoid question answering, more holistic comprehension of a discourse still presents a major challenge (Dunietz et al., 2020). Someone critically reflecting on a text as they read it will pose curiosity-driven, often ope…

Adapting High-resource NMT Models to Translate Low-resource Related Languages without Parallel Data

ACL 2021long

The scarcity of parallel data is a major obstacle for training high-quality machine translation systems for low-resource languages. Fortunately, some low-resource languages are linguistically related or similar to high-resource languages; these related languages may share many lexical or syntactic s…

Enhanced canonical correlation analysis with local density for cross-domain visual classification

ICASSP 2017accepted

Real-world visual classification tasks typically need to deal with data observed from different domains. Inspired by canonical correlation analysis (CCA), we propose an enhanced CCA with local density for associating and recognizing cross-domain data. In addition to maximizing the correlation of the…

Recurrent Neural Network based language modeling with controllable external Memory

ICASSP 2017accepted

It is crucial for language models to model long-term dependency in word sequences, which can be achieved to some good extent by recurrent neural network (RNN) based language models with long short-term memory (LSTM) units. To accurately model the sophisticated long-term information in human language…
