ReasonBERT: Pre-trained to Reason with Distant Supervision [PDF]
Proceedings of the 2021 Conference on Empirical Methods in Natural Language Processing, 2021 We present ReasonBert, a pre-training method that augments language models with the ability to reason over long-range relations and multiple, possibly hybrid contexts. Unlike existing pre-training methods that only harvest learning signals from local contexts of naturally occurring texts, we propose a generalized notion of distant supervision to ...

Modeling Missing Data in Distant Supervision for Information Extraction [PDF]
Transactions of the Association for Computational Linguistics, 2021 Distant supervision algorithms learn information extraction models given only large readily available databases and text collections. Most previous work has used heuristics for generating labeled data, for example assuming that facts not contained in the database are not mentioned in the text, and facts in the database must be mentioned at least once.

Visual Distant Supervision for Scene Graph Generation [PDF]
2021 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.

Biomedical Relation Extraction Using Distant Supervision [PDF]
Scientific 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.

Distant Supervision for Extractive Question Summarization [PDF]
, 2020 Questions are often lengthy and difficult to understand because they tend to contain peripheral information. Previous work relies on costly human-annotated data or question-title pairs. In this work, we propose a distant supervision framework that can train a question summarizer without annotation costs or question-title pairs, where sentences are ...

Distant Supervision for Entity Linking
CoRR, 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
Jisuanji 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
Proceedings - 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

Distant supervision for medical concept normalization
Journal 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 ...

Bridging social media via distant supervision [PDF]
Social 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.
