Relation Extraction with Word Graphs from N-grams

no code implementations EMNLP 2021 Han Qin, Yuanhe Tian, Yan Song

Most recent studies for relation extraction (RE) leverage the dependency tree of the input sentence to incorporate syntax-driven contextual information to improve model performance, with little attention paid to the limitation where high-quality dependency parsers in most cases unavailable, especially for in-domain scenarios.

Reinforced Cross-modal Alignment for Radiology Report Generation

1 code implementation Findings (ACL) 2022 Han Qin, Yan Song

In detail, a shared memory is used to record the mappings between visual and textual information, and the proposed reinforced algorithm is performed to learn the signal from the reports to guide the cross-modal alignment even though such reports are not directly related to how images and texts are mapped.

Enhancing Relation Extraction via Adversarial Multi-task Learning

1 code implementation LREC 2022 Han Qin, Yuanhe Tian, Yan Song

Relation extraction (RE) is a sub-field of information extraction, which aims to extract the relation between two given named entities (NEs) in a sentence and thus requires a good understanding of contextual information, especially the entities and their surrounding texts.

Complementary Learning of Aspect Terms for Aspect-based Sentiment Analysis

1 code implementation LREC 2022 Han Qin, Yuanhe Tian, Fei Xia, Yan Song

Aspect-based sentiment analysis (ABSA) aims to predict the sentiment polarity towards a given aspect term in a sentence on the fine-grained level, which usually requires a good understanding of contextual information, especially appropriately distinguishing of a given aspect and its contexts, to achieve good performance.
