Visual Distant Supervision for Scene Graph Generation [PDF]

open access: yes2021 IEEE/CVF International Conference on Computer Vision (ICCV), 2021
Scene graph generation aims to identify objects and their relations in images, providing structured image representations that can facilitate numerous applications in computer vision. However, scene graph models usually require supervised learning on large quantities of labeled data with intensive human annotation.

Distant Supervision Relation Extraction Based on Focal Loss and Residual Network [PDF]

open access: yesJisuanji gongcheng, 2019
Distant supervision relation extraction based on Convolutional Neural Network(CNN) can extract only single feature,and the standard cross-entropy loss function is not sufficient in balancing the ratio of positive samples and negative samples in datasets ...

Biomedical Relation Extraction Using Distant Supervision [PDF]

open access: yesScientific Programming, 2020
With the accelerating growth of big data, especially in the healthcare area, information extraction is more needed currently than ever, for it can convey unstructured information into an easily interpretable structured data. Relation extraction is the second of the two important tasks of relation extraction.

Improving Distantly-Supervised Relation Extraction Through BERT-Based Label and Instance Embeddings

open access: yesIEEE Access, 2021
Distantly-supervised relation extraction (RE) is an effective method to scale RE to large corpora but suffers from noisy labels. Existing approaches try to alleviate noise through multi-instance learning and by providing additional information but manage

Distant supervision for medical concept normalization

open access: yesJournal of Biomedical Informatics, 2020
We consider the task of Medical Concept Normalization (MCN) which aims to map informal medical phrases such as "loosing weight" to formal medical concepts, such as "Weight loss". Deep learning models have shown high performance across various MCN datasets containing small number of target concepts along with adequate number of training examples per ...

EANT: Distant Supervision for Relation Extraction with Entity Attributes via Negative Training

open access: yesApplied Sciences, 2022
Distant supervision for relation extraction (DSRE) automatically acquires large-scale annotated data by aligning the corpus with the knowledge base, which dramatically reduces the cost of manual annotation.

Bridging social media via distant supervision [PDF]

open access: yesSocial Network Analysis and Mining, 2015
Microblog classification has received a lot of attention in recent years. Different classification tasks have been investigated, most of them focusing on classifying microblogs into a small number of classes (five or less) using a training set of manually annotated tweets.

Distant Supervision for Entity Linking

open access: yesCoRR, 2015
Entity linking is an indispensable operation of populating knowledge repositories for information extraction. It studies on aligning a textual entity mention to its corresponding disambiguated entry in a knowledge repository. In this paper, we propose a new paradigm named distantly supervised entity linking (DSEL), in the sense that the disambiguated ...

Distant Supervision Relation Extraction Combining Attention Mechanism and Ontology

open access: yesJisuanji kexue yu tansuo, 2020
Relational extraction extracts relationships from unstructured text and outputs them in a structured form. In order to improve the extraction accuracy and reduce the dependence on manual annotation, this paper proposes a distant supervision relationship ...

Distant Supervision for Sentiment Attitude Extraction

open access: yesProceedings - Natural Language Processing in a Deep Learning World, 2019
© 2019 Association for Computational Linguistics (ACL). All rights reserved. News articles often convey attitudes between the mentioned subjects, which is essential for understanding the described situation. In this paper, we describe a new approach to distant supervision for extracting sentiment attitudes between named entities mentioned in texts. Two
