Data Augmentation for Code Translation with Comparable Corpora and Multiple References

1 code implementation1 Nov 2023 Yiqing Xie, Atharva Naik, Daniel Fried, Carolyn Rose

One major challenge of translating code between programming languages is that parallel training data is often limited.

Unsupervised Dense Retrieval Training with Web Anchors

1 code implementation10 May 2023 Yiqing Xie, Xiao Liu, Chenyan Xiong

Based on their commonalities, we train an unsupervised dense retriever, Anchor-DR, with a contrastive learning task that matches the anchor text and the linked document.

Open-Vocabulary Argument Role Prediction for Event Extraction

1 code implementation3 Nov 2022 Yizhu Jiao, Sha Li, Yiqing Xie, Ming Zhong, Heng Ji, Jiawei Han

Specifically, we formulate the role prediction problem as an in-filling task and construct prompts for a pre-trained language model to generate candidate roles.

Eider: Empowering Document-level Relation Extraction with Efficient Evidence Extraction and Inference-stage Fusion

1 code implementation Findings (ACL) 2022 Yiqing Xie, Jiaming Shen, Sha Li, Yuning Mao, Jiawei Han

Typical DocRE methods blindly take the full document as input, while a subset of the sentences in the document, noted as the evidence, are often sufficient for humans to predict the relation of an entity pair.

CoRel: Seed-Guided Topical Taxonomy Construction by Concept Learning and Relation Transferring

1 code implementation13 Oct 2020 Jiaxin Huang, Yiqing Xie, Yu Meng, Yunyi Zhang, Jiawei Han

Taxonomy is not only a fundamental form of knowledge representation, but also crucial to vast knowledge-rich applications, such as question answering and web search.

Guiding Corpus-based Set Expansion by Auxiliary Sets Generation and Co-Expansion

1 code implementation27 Jan 2020 Jiaxin Huang, Yiqing Xie, Yu Meng, Jiaming Shen, Yunyi Zhang, Jiawei Han

Given a small set of seed entities (e. g., ``USA'', ``Russia''), corpus-based set expansion is to induce an extensive set of entities which share the same semantic class (Country in this example) from a given corpus.
