Predicting Document Coverage for Relation Extraction (2022.tacl-1)
Copied to clipboard
| Challenge: | Existing methods for predicting document coverage for relation extraction (RE) are limited in their predictive power. |
| Approach: | They propose a task of predicting the coverage of a text document for relation extraction . they analyze a dataset of 31,366 diverse documents for 520 entities . |
| Outcome: | The proposed model achieves an F1 score of up to 46% on two use cases. |
Generative Models for Product Attribute Extraction (2023.emnlp-industry)
Copied to clipboard
| Challenge: | generative models are used for product attribute extraction, a new field in information extraction and e-commerce. |
| Approach: | They analyze generative models for product attribute extraction and demonstrate their utility . they perform experiments on Amazon and MAVE product attribute datasets . |
| Outcome: | The proposed model can generate implicit attribute values, which state-of-the-art models are unable to extract. |
CLEEK: A Chinese Long-text Corpus for Entity Linking (2020.lrec-1)
Copied to clipboard
| Challenge: | Entity linking is a fundamental task in natural language processing, says nigel kilgstrom . existing corpora for entity linking in china are lacking and deficient, he says . kilsmstrom: a new method for entity disambiguation can be developed for Chinese . |
| Approach: | They build a Chinese corpus of multi-domain long text for entity linking . they evaluate the difficulty of documents with respect to entity linking using a measure . |
| Outcome: | The proposed corpus is based on 100 documents from diverse domains and is publicly accessible. |
Building an Ellipsis-aware Chinese Dependency Treebank for Web Text (L18-1)
Copied to clipboard
| Challenge: | ellipsis is a common linguistic phenomenon that some words are left out as they are understood from the context, especially in oral utterance. |
| Approach: | They propose to use a Chinese dependency treebank to facilitate the parsing of web text . they propose to restore omissions and reserve contexts in the web text to improve dependency parsers . |
| Outcome: | The proposed framework enables the parsing of web text from online microblogs. |
Open Information Extraction on Scientific Text: An Evaluation (C18-1)
Copied to clipboard
| Challenge: | Open Information Extraction (OIE) is the unsupervised creation of structured information from text. |
| Approach: | They propose to use two state-of-the-art OIE systems to evaluate the performance of OIE on scientific texts originating from 10 different disciplines. |
| Outcome: | The proposed methods perform significantly worse on scientific text than encyclopedic text. |
Multilingual Knowledge Graph Completion via Ensemble Knowledge Transfer (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods for learning missing facts in knowledge graphs are limited by insufficiency of alignment information and inconsistency of described facts. |
| Approach: | They propose a framework for embedding learning and ensemble knowledge transfer across KGs. |
| Outcome: | The proposed framework improves state-of-the-art methods on language-specific KGs. |
How to Talk to Language Models: Serialization Strategies for Structured Entity Matching (2025.findings-naacl)
Copied to clipboard
| Challenge: | Entity matching (EM) identifies whether two data records refer to the same entity . however, its performance heavily depends on how structured entities are “talked” through serialized text. |
| Approach: | They propose a novel serialization scheme for entities with complex relations in knowledge graphs based on random walks and use open-source LLMs to encode sampled semantic walks for matching. |
| Outcome: | The proposed scheme achieves leading performance on EM in canonical and heterogeneous KGs. |
Regularized Attentive Capsule Network for Overlapped Relation Extraction (2020.coling-main)
Copied to clipboard
| Challenge: | Existing methods to extract relations from distant supervision contain low-quality instances with noisy words and overlapped relations. |
| Approach: | They propose a Regularized Attentive Capsule Network to better identify overlapped relations in informal sentences . they embed multi-head attention into the capsule network as the low-level capsules . |
| Outcome: | Extensive experiments show that the proposed model improves relation extraction. |
Dual Supervision Framework for Relation Extraction with Distant Supervision and Human Annotation (2020.coling-main)
Copied to clipboard
| Challenge: | Existing studies on relation extraction (RE) use labeled training data for relation extraction models but it is expensive and time-consuming. |
| Approach: | They propose a dual supervision framework which utilizes both types of data to train relation extraction models. |
| Outcome: | The proposed framework can predict labels by human annotation and distant supervision without labeling bias since it is expensive and time-consuming. |
