Distant Supervision for Chinese Temporal Tagging
2018Temporal tagging plays an important role in many tasks such as event extraction and reasoning. Extracting Chinese temporal expressions is challenging because of the diversity of time phrases in Chinese. Usually researchers use rule-based methods or learning-based methods to extract temporal expressions. Rule-based methods can often achieve good results

Distant Supervision Learning of DBPedia Relations
2013This paper presents DBPediaExtender, an information extraction system that aims at extending an existing ontology of geographical entities by extracting information from text. The system uses distant supervision learning – the training data is constructed on the basis of matches between values from infoboxes (taken from the Polish DBPedia) and ...

A survey of noise reduction methods for distant supervision
Proceedings of the 2013 workshop on Automated knowledge base construction, 2013We survey recent approaches to noise reduction in distant supervision learning for relation extraction. We group them according to the principles they are based on: at-least-one constraints, topic-based models, or pattern correlations. Besides describing them, we illustrate the fundamental differences and attempt to give an outlook to potentially ...

Distant Supervision for Relation Extraction with Matrix Completion
Proceedings of the 52nd Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers), 2014The essence of distantly supervised relation extraction is that it is an incomplete multi-label classification problem with sparse and noisy features. To tackle the sparsity and noise challenges, we propose solving the classification problem using matrix completion on factorized matrix of minimized rank.

Combining Distant and Partial Supervision for Relation Extraction
Proceedings of the 2014 Conference on Empirical Methods in Natural Language Processing (EMNLP), 2014Broad-coverage relation extraction either requires expensive supervised training data, or suffers from drawbacks inherent to distant supervision. We present an approach for providing partial supervision to a distantly supervised relation extractor using a small number of carefully selected examples.

Similarity-based Distant Supervision for Definition Retrieval
Proceedings of the 2017 ACM on Conference on Information and Knowledge Management, 2017Recognizing definition sentences from free text corpora often requires hand-crafted patterns or explicitly labeled training instances. We present a distant supervision approach addressing this challenge without using explicitly labeled data. We use plausibly good but imperfect definition sentences from Wikipedia as references to annotate sentences in a
