Radical-Enhanced Chinese Character Embedding

, 2014
We present a method to leverage radical for learning Chinese character embedding. Radical is a semantic and phonetic component of Chinese character. It plays an important role as characters with the same radical usually have similar semantic meaning and ...

Adversarial Multi-Criteria Learning for Chinese Word Segmentation

, 2017
Different linguistic perspectives causes many diverse segmentation criteria for Chinese word segmentation (CWS). Most existing methods focus on improve the performance for each single criterion.

Chinese word segmentation at Peking University [PDF]

Proceedings of the second SIGHAN workshop on Chinese language processing -, 2003
Word segmentation is the first step in Chinese information processing, and the performance of the segmenter, therefore, has a direct and great influence on the processing steps that follow. Different segmenters will give different results when handling issues like word boundary.

Neural Chinese Word Segmentation with Lexicon and Unlabeled Data via Posterior Regularization

, 2019
Existing methods for CWS usually rely on a large number of labeled sentences to train word segmentation models, which are expensive and time-consuming to annotate.

Neural Word Segmentation Learning for Chinese [PDF]

Proceedings of the 54th Annual Meeting of the Association for Computational Linguistics (Volume 1: Long Papers), 2016
Most previous approaches to Chinese word segmentation formalize this problem as a character-based sequence labeling task where only contextual information within fixed sized local windows and simple interactions between adjacent tags can be captured. In this paper, we propose a novel neural framework which thoroughly eliminates context windows and can ...

A Levenshtein distance-based method for word segmentation in corpus augmentation of geoscience texts

Annals of GIS, 2023
For geoscience text, rich domain corpora have become the basis of improving the model performance in word segmentation. However, the lack of domain-specific corpus with annotation labelled has become a major obstacle to professional information mining in

Mostly-Unsupervised Statistical Segmentation of Japanese Kanji Sequences

, 2002
Given the lack of word delimiters in written Japanese, word segmentation is generally considered a crucial first step in processing Japanese texts.

Normal‐Appearing White Matter Injury Mediates Chronic Deep Venous Hypoxia and Disease Progression in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To explore how cerebral hypoxia and Normal‐Appearing White Matter (NAWM) integrity affect MS lesion burden and clinical course. Methods Seventy‐nine MS patients, including 13 clinically isolated syndrome (CIS) patients and 66 relapsing–remitting multiple sclerosis (RRMS) patients, and 44 healthy controls (HCs) were recruited from ...

High‐Resolution MRI Revealed Different Etiology‐Specific Associations With Cerebral Infarction in Adult Moyamoya Vasculopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐resolution MRI enables detailed assessment of intracranial vessel wall pathology in moyamoya vasculopathy. We aimed to classify adult moyamoya vasculopathy etiologies using high‐resolution MRI and to examine subtype‐specific associations between high‐resolution MRI features and ischemic infarction.
